MESSAGE FROM THE CEO

WORKING TOWARDS A WORLD-CLASS PLUMBING AND HEATING WORKFORCE This year will undoubtedly bring new challenges and opportunities and I hope it is a very successful year for you all. However, it would be remiss of me not to look back briefly on 2017 and thank all existing and new members for their support.

Kevin Wellman, CIPHE CEO kevinw@ciphe.org.uk

F

ollowing approval by voting members and the Privy Council, CIPHE adopted its new Bye-Laws.

The changes which were summarised in a previous editorial have enabled the Board to implement a number of activities within the Strategic Plan, aimed at growing membership and enhancing CIPHE’s technical provision. I am especially delighted to report that 2017 ended with an overall increase in membership, which is the first such increase for many years.

The addition of new membership services, the launch of the techtalk series and our Chartered Engineer license have resulted in extremely positive feedback from members and stakeholders. We are not resting on our laurels and to ensure we are maximising our membership offering, we have commenced a Member Engagement Programme in which we will be seeking your response to questionnaires, surveys and other communications. In addition, we will be providing guidance on the new General Data Protection Regulations which will be effective from 25th May, if you have your own contact database you will need to ensure you are compliant.

APPRENTICES

SPRINKLER SYSTEMS

Later this year we will see the introduction of the long awaited Trailblazer Apprenticeship and there is no doubt that the need for ‘Fit for Purpose’ training is more important than ever before.

The Plumbing and Domestic Heating Technician Apprenticeship Board announced last November that the Apprenticeship Assessment Plan for England had been agreed and published by the Institute for Apprenticeships (IfA). The Assessment Plan was initially submitted and approved by the IfA in March 2017, with conditions, which the Board worked through until early November. The Assessment Plan can be accessed at http://tinyurl.com/o5jho5w. The Apprenticeship Board was assembled and administered by APHC and CIPHE, which are recognised as being the two leading membership organisations within the plumbing and heating industry. We uniquely joined forces to create an industry partnership set on achieving the ultimate goal of producing a world-class plumbing and heating workforce.

With ongoing dialogue regarding Brexit and Government’s Migration Advisory Committee, concerns regarding the skills shortage, training should be high on the agenda.

The shortage of qualified and experienced installers amongst the sprinkler industry has also been raised in recent months. A number of local authorities reacted quickly after last year’s tragic Grenfell Tower fire and have arranged for sprinkler systems to be installed.

It would be premature to comment on anything specific to Grenfell as the Public Inquiry has the responsibility for proposing recommendations emanating from the disaster. However, if following a review of a fire safety plan it is agreed that sprinklers should be installed, it is imperative that they are designed and installed by competent individuals. I have spoken to a number of members who have expressed interest in attending training on sprinkler systems and if this is of interest to you it is important to ensure that the training is accredited by the Institution of Fire Engineers, see the following link: http://www.ife.org.uk/.

If you would like your voice to be heard or you would like to help influence CIPHE’s decision-making, please do get involved with our work and activities.

There is still time to submit nominations to the Board of Trustees and for Vice President, if you would like further details on these responsibilities please contact me.

ALL THAT’S HAPPENING IN THE PLUMBING & HEATING WORLD

BAXI BACKS CHANGES TO BUILDING REGS

CIBSE CERTIFIES ALTECNIC’S CPD PRESENTATION

Boiler manufacturer, Baxi, has welcomed revisions to legislation that promote energy efficiency by updating minimum requirements for boiler installations in existing buildings.

Changes to technical standards under Building Regulations Approved Document L1b (also known as Boiler Plus) are due to come into effect in April 2018 and will apply to England only.

The measures include a minimum 92 percent ErP space heating energy efficiency rating for all gas boilers together with mandatory time and temperature control for all boiler types. Combi boiler installations must include one of the following options: weather compensation, load compensation, flue gas heat recovery or smart control with automation and optimisation functions.

Jeff House, Regulatory Marketing Manager at Baxi said: “Given that 20 percent of the UK’s carbon emissions comes from domestic heating, these new standards will result in huge savings and reduce carbon emissions by two MtCO2e (metric tons of carbon dioxide equivalent) in the fourth Carbon Budget and 3.2 MtCO2e in the fifth Carbon Budget.

The Chartered Institution of Building Services Engineers (CIBSE) has certified another CPD presentation for sealed heating systems, from CIPHE Industrial Associate, Altecnic.

Altecnic’s Robokit sealed system solutions make life easier for installers by eliminating the feed and expansion tank and associated pipework, which also reduces any risk of corrosion and noise in the system. Altecnic’s CPD certification is valid until May 2019 and its presentation covers sealed primary central heating systems, which are the most commonly used form of heating system throughout Europe.

Gary Perry, Altecnic’s OEM Sales & Technical Director, said: “This underlines the standards that we operate to when developing and supplying sealed heating systems.”

“This is good news for the environment and also the industry, when considered as part of the Government’s Clean Growth Strategy, which is in part designed to drive economic growth.

“But the consumer will be the biggest winner here. Statistics show that less than half of domestic heating systems currently operating in the UK are fitted with a full set of recommended controls, resulting in an energy wastage issue. The new minimum requirements will improve the efficiency of new boiler installations thereby saving consumers money on their energy bills.”

APPRENTICESHIP GRADUATION 2017

Steve Willis Training Centres 2017 apprenticeship graduation evening

The apprentices received their certificates to mark the completion of their gas, plumbing and electrical apprenticeships and several special recognition awards were also presented including Apprentice of the Year in each trade. The awards were sponsored by companies including Worcester Bosch, Intergas and Danfoss, who all sent representatives to present the trophies.

Speakers at the events included CIPHE President, Geoff Westall, who congratulated the apprentices and emphasised the importance of ongoing training to ensure engineers keep up-to-date with their trades.

Geoff presented the Plumbing Apprentice of the Year award winner, Theo Hines, with a year’s membership of CIPHE and a selection of books.

BUILDING ACCESS TO SAFE SANITATION As most of us know, mobile phones have now become an integral part of our lives.

What you may not know, however, is that you are more likely to have a smartphone in your pocket than you are to have access to a clean, functioning toilet. One in nine people worldwide lack access to safe drinking water and around half of hospital beds worldwide are currently occupied by people suffering from water-based diseases.

To start making a difference to lives around the world, Xylem has launched Waterdrop, a scheme designed to involve customers in the work being carried out to support people in need around the world.

As a member of the Waterdrop scheme, customers collect points, or 'drops', by learning about, selecting or specifying Xylem’s products or services for commercial building services applications.

For every drop collected, Xylem donates 1USD towards the construction of water towers for communities. Each drop also enters customers into a draw to become part of the volunteer team that builds and installs these towers at locations around the world.

Since Waterdrop was launched, the business has collected enough 'drops' to fund 28,190,000 litres of clean water.

For more information about the scheme visit www.xylemwaterdrop.com

NOT ENOUGH FUNDING SUPPORT FOR ELECTRICALLY HEATED HOUSEHOLDS Upgrading outdated static electric storage heaters in half a million electrically heated homes could help to close a combined fuel poverty gap of £160million every year, but according to a new report by Glen Dimplex Heating & Ventilation, they are being excluded from energy efficiency improvement programmes.

More than 3.2million households in England and Scotland are fuel poor according to official statistics. Around 15 percent of these – almost 500,000 households − use electricity to heat their homes and are paying over the odds for their heating because of a legacy of ageing electric storage heaters and incorrect specification.

Despite this, Government incentive schemes are failing to offer the funding needed to support heating system upgrades in electrically heated homes with modern, smart appliances that can slash heating bills.

The average annual fuel poverty gap in England – the difference between a household’s typical energy bill and the value that their bill would need to be in order for that household to come out of fuel poverty – is £353.

The report highlights the potential of modern, smart electric heating appliances including direct-acting electric panel heaters and high heat retention heaters, which draw energy during off-peak periods to deliver heat at any time of the day or night. Both can include intelligent controls which react to changes in climatic conditions and occupant behaviour for enhanced efficiency.

Smart electric heating appliances draw energy during off-peak periods

KOHLER MIRA WINS QUEEN'S AWARD

Liz Hazeldene, Managing Director, of Kohler Mira, received the Queen’s Award for Enterprise: Innovation award on behalf of the company and its workforce recently, at Mira’s production facility in Hull.

The award is for the Mira Flight Safe range of anti-slip shower trays, which was developed in response to market demands for bathroom products that deliver multigenerational bathroom installations.

The Queen’s Awards for Enterprise are the UK’s most prestigious business awards and are designed to celebrate and encourage business excellence in the UK. Key to the award for Mira Flight Safe, was the company’s ability to demonstrate a high degree of product innovation and high levels of Corporate Social Responsibility.

FUTURE OF OFF-GRID HEATING

Following the publication of the Government’s Clean Growth Strategy in the autumn, Paul Rose, CEO of OFTEC, the trade association for the UK oil heating industry, said: “Consumers need practical, affordable measures to improve energy efficiency and reduce carbon emissions from UK homes.

“We believe our two-stage solution is the most cost-effective way to deliver significant carbon reduction and energy efficiency gains for the UK’s 1.5 million oil heated homes. Our approach would see a boiler replacement programme in the short term (2018-2022), followed by the introduction of a low carbon liquid fuel as a direct replacement for kerosene.

“We would like to see the important role that low carbon liquid fuels could play in the future of domestic heat recognised, alongside bio gas (bio methane), in forthcoming revisions to the Renewable Heat Incentive (RHI).

“It is vital that off-gas grid homes do not continue to be marginalised by heat policy and are offered a range of competitive and cost-effective options, similar to those on the gas grid.

“Doing nothing is not an option and all realistic, cost-effective measures to achieve this must now be considered.”

n early November, I was pleased to visit EAS Mechanical Ltd to present a plaque to the Managing Director, Eamon Wilson, in recognition of their new status as a CIPHE Approved Training Centre. The presentation was followed by a tour of the facilities when I was able to talk with the students about their training and work experience.

The centre had recently been represented at WorldSkills in Abu Dhabi by their student, Daniel Martins, who won a bronze medal in Plumbing and Heating for the United Kingdom.

The recipients were: • Edward Booth (Boston), • Jake Bishell (Grimsby) and • Danny Ralph (Lincoln).

Each student received a certificate, trophy, CIPHE Plumbing Engineering Services Design Guide book and manufacturers’ goody bags. As Edward Booth was unable to attend, his tutor, Sergio Afonso, received the award on his behalf.

The Branch President presented the President’s Trophy to the Branch Vice-Chairman, Gary Payne, and also proposed a toast to our sponsors; Graham Plumbers' Merchants, Pegler Yorkshire, Aqualisa and Chameleon Print. Also in attendance were Past Presidents, Tony Kite and Peter Ashby.

The following week I visited the PHEX exhibition at Chelsea Football Stadium to meet existing and potential new members on the CIPHE stand.

Later that day, the presentation of the 2017 CIPHE Apprentice Awards were held in the Bonetti Suite at the stadium. (See the full report on page 16 of this issue).

There were three categories, namely: Heating, Plumbing and Vulnerability and the respective winners were Daniel Martins, James Boyle and Robbie McNeil.

Introducing the event, CIPHE CEO, Kevin Wellman, said that Einstein once said that if he had his time again, he’d be a plumber. Kevin said: “With people like him, who clearly recognise the value of plumbing and heating, it bodes well for the future.

“Ours is a skilled profession, it takes a lot of hard work to become fully qualified, but it is a wonderful industry to be involved in.”

Before the apprentices received their awards, CIPHE Membership Director, Tim Sainty, highlighted the judge’s comments on why and how they won

their awards, he said: “I had the privilege of watching the judges deliberating over who the winners should be. The debates regarding all the entrants were very detailed and are testament to the achievement of each and every one of the winners.

“As a professional body dedicated to the high standards and professionalism of the plumbing and heating industry, it is fantastic to see such people embarking on their careers in it.”

Paul Massey, Chairman of the CIPHE’s Industrial Associates (IA) Development Group reminded the audience at the awards that one of the objectives of the CIPHE is to develop young people, who will be able to protect the future of the CIPHE and its professional membership. He said: “Supporting apprentices in a business comes at a cost, but it is a cost that is necessary for all of us in order to outlaw rogue traders and to protect vulnerable consumers in their homes.”

DEDICATION AND COMMITMENT Richard Soper, CIPHE Director of Development sees a great future for vocational training, thanks to the new Trailblazer Apprenticeships and the T-Level action plan, which will be as rigorous and respected as A-Levels. He said: “It is great to see these young guys winning these very important awards.

“When something goes wrong in someone’s house or business, unfortunately, not everybody gets a good plumber or heating engineer turn out to do the job. The CIPHE ethos is very much about the safety and health of the public, so we must raise standards. It is so important that the young people who have won awards today go out and shout about the awards and why they’ve won them. It shows their commitment and dedication to their trade.”

TRAINING

QUALFICATIONS ARE KEY TO A SUCCESSFUL CAREER Marie McCaffrey, CIPHE Membership Manager explains how members can gain more qualifications and further their careers.

2

017 saw a surge in transfers to different categories of membership with the CIPHE. After we contacted you, many of you advised us that yes, you had in fact gained further qualifications and were keen to take the next step on the membership ladder. We would like to encourage more of you to do this as part of your professional development.

Marie McCaffrey, Membership Manager

‘mycareerpath’ We also introduced ‘mycareerpath’ for members to use to record and plan their Continuing Professional Development (CPD). You can use this when you attend a course; just scan the certificate and add it to your record. Reading technical journals also counts towards your CPD so don’t forget to include this too. Attendance at exhibitions can also be added to your CPD record. You can use ‘mycareerpath’ to help you plan your CPD, identifying any gaps or updates required in your knowledge so that you can plan ahead for the year.

CIPHE AT EXHIBITIONS The CIPHE attended seven exhibitions across the UK over the course of 2017 and welcomed the support of some of our members as Membership Ambassadors on the stand. The exhibitions provide an ideal opportunity for the Institute to raise its profile to thousands of plumbing and heating engineers who visited throughout the year. A number of colleges and manufacturers also came on board as a result and we were pleased to see existing members introduce colleagues and friends to the Institute, taking advantage of our offer of complimentary M&S vouchers through our ‘Member get Member’ scheme.

ENGINEERING COUNCIL A number of members who are also registered with the Engineering Council have been called at random to submit details of their CPD for 2017. It is important that those of you who have been called, submit your CPD record by the end of January 2018, as the Engineering Council requires us to submit a sample to them.

Applications for registration with the Engineering Council are increasing. The CIPHE is particularly proud that 2017 brought approval from the Engineering Council for an extended licence to award Chartered Engineer status, in addition to the licences already held to award Incorporated Engineer and Engineering Technician status. We received over 200 initial enquiries following announcement of the award of the CEng licence and interest amongst members has been constant. We now have around 60 candidates who are at various stages in the application process; from waiting to submit their Professional Review report for assessment, through to those who have had their report approved and are waiting to be called for Professional Review Interview. Just to remind you, the exemplifying academic standard for Chartered Engineer registration is a BEng (Hons) degree. There is an alternative route known as the technical route for those who believe that they are able to meet the Competence and Commitment statements in the Engineering Council’s UK-SPEC, but who don’t necessarily have the academic qualifications.

Similarly, the academic route to Incorporated Engineer requires the member to have a degree but again, there is a technical route for those who can match the UK-SPEC Competence and Commitment statements.

If you have a NVQ Level 3 or Advanced Craft certificate or equivalent, you are eligible to apply for Engineering Technician registration. This means that you will be able to use the designatory letters EngTech after your name. There is also a route to EngTech if you have a NVQ Level 2 or Craft certificate.

ALTERNATIVE ROUTES TO SUCCESS Another means through which to achieve professional recognition is through the awards of the Apprentice, Journeyman or Master Plumber certificates. These prestigious awards are given by the CIPHE, the Worshipful Company of Plumbers and City & Guilds. Further information on the criteria for each award can be found on the CIPHE website at www.ciphe.org.uk under ‘Membership Services’ then ‘Awards’.

Finally, but by no means least, we have already visited around 18 Approved Training Centres and Colleges since the start of the academic year, with many more to come. We are very keen to support newcomers to the profession and to instil in them how important it is to be ‘Proud to be a Professional’.

MORE ADVICE If you would like further advice on your own professional development or guidance on transferring to a different category of membership or applying for registration, please email Marie McCaffrey, Membership Manager on mariem@ciphe.org.uk

PLUMBEXPO THE REGIONAL TRADESHOW FOR PROFESSIONAL HEATING AND PLUMBING INSTALLERS

NORFOLK BRANCH Last September, Norfolk Branch held a technical evening on heat loss and U-valves in buildings. Members appreciated the refresher on this subject and it provoked much discussion.

In November, members visited Orange Heating Supplies in Norwich.

Managing Director and CIPHE member, Richard Brown, and his team spoke to members about air and ground source heat pumps. Members were divided into two groups and were given a tour of the showroom and a demonstration to show the advantages of press fittings. A Q and A session produced a lively discussion.

A week later members met again; this time at the Forum in Norwich city centre. The Forum is an iconic building which opened in November 2001. It houses the BBC studios, the Millennium Library, the Forum Trust, two restaurants and a shop. Steve Falvey, Services and Facilities Manager, gave members a ‘behind the scenes’ tour, explaining how the sprinkler system worked, showing them the air control units and the fresh water storage tanks.

Members of the Committee are working hard to keep the Norfolk Branch running, but they want to appoint a new Branch Secretary this year. If you are interested in joining the friendly team, please let them know at lindatuttle538@btinternet.com

TRAINING MATTERS

TRAINING MATTERS ALL THAT MATTERS IN THE TRAINING WORLD

PROFESSIONALISM: LEARNED OR EARNED?

Jenni Preston

T

he CIPHE’s Apprentice Awards 2017 showcased some of the best projects and stories coming out of the training world in 2017. With categories in plumbing, heating and vulnerability, qualities such as politeness, punctuality and empathy shone through, just as much as the physical skill and mental aptitude shown by the students for their chosen profession. At the Apprentice Awards it was clear that the families, lecturers and employers were proud of their achievements and that there is no doubt that the award winners were 'Proud to be a Professional'. (See page 16 for a full report).

It got me pondering about the whole concept of professionalism − where does it come from – is it intuitive, is it learned from the start of your career or earned as you progress with knowledge and experience?

How do we make it a necessary quality, rather than a ‘nice to have’?

If you look up ‘professionalism’ in the Oxford Dictionary it is defined as: ‘The competence or skill expected of a professional.’ So what are we looking for in a professional plumbing or heating engineer?

Some of this is definitely earned − you cannot achieve it without first going through the education system and gaining practical experience − indeed it may take many years post-qualification to truly master all the skills you need.

PROFESSIONALISM Earned professional attributes include: • Qualified to industry recognised standards; • Experienced in a range of systems, products and troubleshooting situations; • Knowledgeable about regulations, products, industry issues and the bigger picture in regard to water sustainability and carbon footprint; • In command of a vast skill set, ensuring engineers are able to deal with a range of

14

journal

|

situations (both physically and mentally); • Up-to-date with industry advances, products and changes to regulations, through a commitment to lifelong learning via Continuing Professional Development (CPD); and • Values membership of competent person schemes and professional bodies.

Then you have those intuitive aspects of professionalism, which are just a part of who you are and how you approach your work.

These qualities can be possessed naturally, or learned (especially with maturity), as the student grows and develops. You can have these attributes regardless of your physical skill, knowledge or experience.

QUALITIES INCLUDE: • Politeness; • Empathy; • Integrity; • Punctuality; • Honesty; • The ability to communicate well in a range of situations; • Positive attitude; • Willingness to learn; • Tidy/organised; • Ability to push yourself; and • Pride in a job well done.

It’s clear that professionalism is a wide umbrella term for a number of key qualities.

It should be noted that the above attributes are not readily recognised by the academic emphasis of secondary education. Students who have often been maligned, will grow in confidence and really gain a passion for their chosen subject once they realise these natural abilities are vital to their new role. The argument for recognising and encouraging these professional attributes from the very start of a student’s career is strong.

So are the apprentices who shine at awards a rare breed when it comes to going

above and beyond or showing exceptional skill? The truth is, that students will display a number of the skills listed above and everyone has the potential and the choice to become a professional.

TRAILBLAZER APPRENTICESHIPS There are of course steps being taken to install professional recognition from the very start of the apprenticeship route. The new Trailblazer Apprenticeships bridge the gap between earned and learned skills, raising the bar by ensuring apprentices qualify for Engineering Technician (EngTech) status with the Engineering Council as part of their training.

While training providers, lecturers and employers bear the brunt of developing apprentices, bodies such as the CIPHE also have a role to play. The CIPHE is a strong believer in developing a culture of professionalism in the industry and has membership levels to recognise those who have fledgling professional qualities, but still have to develop the vast array of earned professional skills.

FREE TECHNICAL INFORMATION Joining the CIPHE as either a Trainee Member or newly qualified Affiliate Member associates students with professionalism from the very start of their career. With access to free technical information including p&he Journal, the CIPHE’s e-learning platform and revision package for learners, membership can really boost students’ technical knowledge and understanding (both pre-and post-qualification).

The best news is that for those studying at CIPHE Approved Training Centres, Trainee membership is currently free, courtesy of City & Guilds. For more information, contact Marie on 01708 463104 or email mariem@ciphe.org.uk

CIPHE APPRENTICE AWARDS 2017

OUTSTANDING APPRENTICES To highlight the excellent work of young people who have found their vocation in the plumbing and heating sector, the CIPHE launched its Apprentice Awards for 2017.

A

pprentices and trainers waited anxiously to hear the results of the Apprentice Awards 2017 at a special ceremony held at PHEX Chelsea, on Wednesday 15th November.

The judges; Tracey Richardson and Tony Kite, (who are both involved in vocational training) and Geoff Westall, the CIPHE National President, were impressed by the high quality of the projects submitted, especially as the apprentices regularly went way above and beyond what they needed to in their work.

With stiff competition in all three categories, the exceptional winners were: • Daniel Martins (heating category) • James Boyle (plumbing category) and • Robbie McNeil (vulnerability category).

Each of the three apprentices received £500, a trophy, a copy of the CIPHE Plumbing Engineering Services Design Guide and gift vouchers from sponsors; Ridgid Tools and Screwfix.

There was very well-deserved praise from the apprentices’ training providers and employers for their commitment and work ethic.

that Daniel shows. Pete said: “In 20 years of managing apprentices, I have never witnessed such dedication from someone so young.”

DANIEL MARTINS, HEATING APPRENTICE WINNER

JAMES BOYLE, PLUMBING APPRENTICE WINNER

Daniel Martins, the heating category winner, is no stranger to awards; having just won a bronze medal at WorldSkills 2017 in Abu Dhabi. Daniel’s trainer, Eamon Wilson, from EAS Mechanical Limited, pointed out that Daniel has always exceeded expectations, saying his politeness, coupled with his willingness to listen and learn were key qualities that helped him achieve consistently.

Daniel’s employer, Pete Curtis of Briggs & Forrester, added that Daniel is an exceptional employee and is highly respected right across the company.

Pete puts this down to the unprecedented level of commitment and determination

Plumbing category winner, James Boyle received similar praise. James goes to South Gloucestershire & Stroud College and is employed by MG Plumbing in Bristol. His lecturer, Scott Manson, commended James not only on his 100 percent attendance record, but also on his role-model status, saying he always demonstrates great skill in all his plumbing assessments. Scott said: “James is a leader who pushes himself but he also encourages his fellow learners to make sure that they understand and he helps to create a very strong learning environment during lessons.”

James’ employer, Matthew Shortman, considers him to be a model apprentice and also commended him on his attitude and commitment to work.

Winner of the Vulnerability category, Robbie McNeil is a student at Cardonald Campus and is employed by Lambert Contracts Limited in Paisley. This special category celebrates apprentices who go way above and beyond the call of duty to help vulnerable people – the elderly or ill and those with disabilities or who have little support – at a time when they are desperately in need. As members will know, this is a sector of the industry, which is fundamental to the ethos of the CIPHE. When he was very young, Robbie decided to follow in his grandfather’s footsteps and become a plumber. It seems to have been a good choice, as the judges agreed unanimously that Robbie should be given this award after learning of the efforts he had gone to in order to help a customer whose heating had broken down while they were on dialysis.

CIPHE APPRENTICE AWARDS 2017

Robbie’s employers said that he is very eager to learn, that his positivity is a key strength and that great things are expected from him because of the standards he has set. His ability to work with and learn from his tradesmen is exceptional.

Presenting the awards, CIPHE National Chairman, Geoff Westall congratulated all three winners on their hard work and encouraged them to continue. He said: “Throughout your career I hope that you will continue to learn and as you gain knowledge and experience, the CIPHE can help with your career pathway through

CAREER PROGRESSION Early in the New Year, the Trailblazer Apprenticeship Scheme will be introduced, which will encompass the required knowledge up to and including Level 3 status.

COVER STORY - SUSTAINABILITY

WATER ON WORLD STAGE IN LONDON Innovative building services systems, designed by engineering, environment and design consultancy Sweco UK Limited, have contributed to the design of Bloomberg’s new European headquarters being named as the world’s highest BREEAM-rated office building as Kris Wojcik, Project Engineer at Sweco reports.

T

he construction industry aspires to develop buildings that use less energy and make more effective use of the Kris Wojcik, Sweco UK Limited, world’s resources. kris.wojcik@sweco.co.uk Reducing our water www.sweco.co.uk consumption and better overall use of water has become increasingly important as supplies become more stressed and the water industry faces a challenge in meeting future demands.

Buildings cannot be considered sustainable if they waste large quantities of potable water just for flushing toilets.

The design brief that Sweco received from Bloomberg was to make its new European headquarters in London sustainable in all aspects, including water saving. Sweco evaluated numerous well-established technologies like water recycling systems, ultra-low flush toilets and water-saving showers. Emerging or out-of-context technologies were also explored, including water desalination, black water treatment and re-use for toilet flushing, solar-powered devices, extracting water from air and vacuum drainage. The latter came out as viable and offered distinct benefits.

BREEAM EVALUATION BREEAM is the world‘s leading sustainability assessment method and

was developed by the Building Research Establishment (BRE) in the UK. Its evaluation range includes many elements associated with building construction and use, such as energy consumption, waste and pollution generation, ecology and water use. The water consumption credits are awarded based on a calculator, which compares a benchmark building's performance against the estimated water efficiency of the proposed building design, including its specified fittings and water saving systems. The improvement is compared with the baseline and credits awarded accordingly. Some technologies provide a greater opportunity to reduce water consumption than others and therefore perform better in water audits.

COVER STORY - SUSTAINABILITY

A combination of well-established water recycling systems and innovative vacuum toilets were selected for the Bloomberg building. Harvested rainwater, together with water recycled from cooling tower bleed-off and grey water recovered from basins and showers, is recycled and treated to flush vacuum toilets.

VACUUM TOILETS Before the vacuum system was selected, many aspects of the delivery were considered including the WC pan range, which is limited when compared to those available for traditional gravity drainage.

The Norwegian manufacturer, JETS, expressed willingness to collaborate with the design team on WC pan design development and selection.

Vacuum toilets are common on trains, aeroplanes and ships etc, but in order to understand how this pioneering solution would perform in a project-specific setting, a mock-up installation with multiple toilet cubicles was set up in a London warehouse.

Collaboration with the manufacturer and its representative (Otter Vacuum) at an early stage allowed the design team to experiment with a prototype noise-reducing device. As a result, a silencer device was developed and featured in the final installation.

The mock-up installation also played a key role in spatial coordination, which resulted in an optimised arrangement and satisfactory maintenance access.

The design and 3D modelling of the vacuum drainage system involved some adjustments to accommodate different design parameters when compared to the traditional gravity approach. The limitations Bloomberg toilet mockup

of gravity drainage Bloomberg vacuum systems no longer drainage plant apply, allowing a more flexible approach to be adopted including multiple up and down routing and smaller pipe diameters. As the position of appliances is no longer dictated by the distance from the stack, the number of vertical stacks and slab penetrations can also be significantly reduced. That additional flexibility proved to have major benefits when coordinating competing services in a highly serviced environment.

Working with small diameter pipework was an added benefit and a lightweight push-fit stainless steel pipework system was selected for robustness and ease of installation.

The Bloomberg building contains more than 500 toilets and urinals, served by multiple vacuum generation stations. To increase the general system resilience, some strategically located disabled toilets are connected to a separate gravity drainage system.

Due to the nature of the vacuum system operation, odours are drawn into the drainage system which provides a supplementary air extract system while the risk of flush water atomisation is greatly reduced, providing positive health benefits.

Vacuum toilets use less than one litre of water per flush against 4.5 or six litres used for traditional toilets. The overall water conservation systems implemented in

Bloomberg’s London office will save 25 million litres of water in the first year of operation, with a net zero mains water usage for toilet flushing. This solution attracted additional BREEAM credits for innovation.

OUTSTANDING Bloomberg’s new European headquarters has been rated as Outstanding under BREEAM UK New Construction 2014: Offices (Fully Fitted). A credit score of 98.5 percent was awarded. This is the highest score achieved at design stage by any major office development globally.

Alan Yates, Technical Director of BRE Global's Sustainability Group said: "What sets the Bloomberg building apart is its relentless focus on innovation and its holistic, integrated approach to sustainable construction and design. Projects like these are really important in giving confidence to the industry to experiment."

INTERESTING FACTS • Bespoke integrated ceiling panels combine heating, cooling, lighting and acoustic functions in an innovative petal-leaf design. The system with 500,000 LED lights, uses 40 percent less energy than a typical fluorescent office lighting system.

• Rainwater from the roof, cooling tower bleed-off water and grey water from basins and showers, is captured, treated and re-used to flush vacuum toilets.

• Natural ventilation: When ambient weather conditions are temperate, the building’s bronze blades can open and close, allowing the building to operate in a ‘breathable’ natural ventilation mode, reducing mechanical ventilation and cooling equipment energy consumption.

• Smart CO2-sensing controls allow air to be distributed according to the approximate number of people occupying each zone of the building at any given time. The ability to dynamically adjust airflow in response to occupancy patterns is expected to reduce CO2 emissions by approximately 300 metric tonnes each year.

• On-site combined heat and power (CHP) generation centre supplies heat and power in a single, efficient system with reduced carbon emissions. Waste heat generated from this process is recycled for cooling and heating and is expected to save 500-750 metric tonnes of CO2 each year.

THE EFFECTS OF AN AIR TO WATER HEAT PUMP DESIGN ON RUNNING COSTS AND EMISSIONS

Kamlesh Vadukul, Sales Manager at LG Heating Solutions

Kamlesh Vadukul, Sales Manager at LG Heating Solutions, takes a detailed look at the design and successful operation of air source heat pump heating and hot water systems.

A

s renewable heating options grow in popularity, air source heat pumps (ASHP) are increasingly being seen as a mainstream heating alternative in UK homes. As standalone heating options or as part of a hybrid heating system, they offer cost effective, energy-efficient and low maintenance options – something that has seen them increasingly used in social housing developments as well as in private new build and replacement heating systems.

So why use an air source heat pump as opposed to a traditional boiler to drive the heating system? The two key reasons are the reduced running costs and a reduction in harmful emissions.

While heat pumps are seen by many simply as replacements for boilers, that’s not what they are. The technology is quite different and the design parameters are inevitably different too. Careful design can offer improved running costs and reduce CO2 emissions in comparison to boilers,

(kg per kWh) is highest from electricity because electricity is generated at low efficiency. The figures are around 0.2kg per kWh from gas, 0.23 from LPG, 0.31 from oil and 0.52 from electricity.

But electrically driven heat pumps are considerably more efficient than boilers – the COP of a heat pump will usually fall between 3 and 4.5 while a boiler will usually be between 0.75 and 0.9, but certainly below 1.0.

So when you look at the figures for the emissions per kWh of heat generated, oil will generate 0.35kg CO2/kWh, the LPG figure is 0.26, gas is 0.245 and the heat pump driven by electricity will only generate 0.17 kg CO2/kWh. These figures assume a comparison of a boiler with an efficiency of 90 percent (COP of 0.9) and an electric heat pump with a COP of 3.0.

It’s important to realise that COP is not constant. They are quoted by Eurovent Electric at 7oCwiring outdoors and 35oC water flow Electric (for detailswiring refer to wiring (for detailsinrefer to wiring diagrams the manual) temperature. diagrams in the manual) It’s clear that COP is better 1) Power supply Outdoor unit when outdoor 1) Indoor-Outdoor Power supply Outdoor unit temperatures are higher and 2) unit connection 2) Power Indoor-Outdoor unit connection 3) supply Indoor unit 3) Power supply Indoor unit worse at lower 4) Power supply Electric Tank temperatures.

Let’s take a closer look at how CO2 emissions from an ASHP compare to those from a conventional boiler. You’ll know that nominal COPs (coefficient of performance) can be 4 or higher, which sounds very attractive.

The actual COP will vary depending upon the application that you’re targeting. In the wrong application, COP can be very poor and the CO2 emissions can be worse than those associated with a gas boiler.

Much of the electricity in the UK is still generated from fossil fuels, (47 percent) − gas, coal, nuclear and oil. So around Flow line 53 percent is from renewable sources – a Return line significant rise over the past few years.

are higher when water flow temperatures are reduced and lower at increased temperatures. For example, if you take the average monthly temperatures at Heathrow Airport, sub-zero temperatures do occur on some winter days, but very rarely. Mean temperatures are 4oC and above, even in the coldest months of the year.

COPs will vary depending upon the kW rating of the heat pumps and to a degree, depending on the manufacturer of the equipment, as technology, whilst similar, will clearly vary. In the same way, COP reduces at higher water temperatures. If the water temperature is raised to 55oC and the

CPD costs = the cost of electricity per kWh over the COP. The boiler’s running costs are equal to the cost of fuel per kWh over the boiler efficiency. The COP at which the running costs would be equal for a boiler and a heat pump can be expressed as the gas boiler efficiency multiplied by the electricity cost per kWh over the boiler fuel cost per kWh.

time. Heaters used indiscriminately can considerably reduce the net COP so careful programming is required. When sizing a heat pump, it is worth remembering that a smaller heat pump will require electric heaters to kick in earlier and larger heat pumps may eliminate the need for electric heaters altogether.

SIZE OF AIR TO WATER HEAT PUMP

HEAT EMITTERS

When looking at the heat pump’s output, it makes sense that the maximum output is required when the outside temperature is lowest. The heat pump output declines as outside temperature decreases. The output at the design minimum temperature needs to be considered. Output can be considerably less than the nominal output – which you’ll recall was quoted at 7oC outside, 35oC water temperature. On the typical capacity table reproduced in this article, you can see that at an outdoor temperature of 7oC and low water temperature of 35oC, the total heating capacity required is 12kW and the power input required to achieve it is 2.67kW – a COP of just under 4.5. If the outside temperature drops to -15oC, and the low water temperature remains at 35oC, the total heating capacity required is 9.4kW and the power input required to achieve it is 4.10kW – so the COP drops to 2.29. If the outdoor temperature goes up to 18oC and we stick with a low water temperature of 35oC, the total heating capacity requirement is 14.51kW and the power input required to achieve that is just 2.65kW – the COP is now 5.48.

If you’re using radiators to share the heat around a property that uses an air source heat pump, it’s key to remember that radiators will need to be oversized to accommodate this. Radiator capacity is normally quoted at 70oC. At 40oC the output is only one third of nominal so the radiator surface area needs to be trebled compared to a system designed for a gas or oil boiler. This can be achieved by increasing the size of the radiator or using double or triple panel radiators, each panel with fins, to achieve the desired heating surface area on each radiator.

We discussed earlier the fact that ASHPs might not always be appropriate for the design. This is particularly likely if the heat pump is to replace an existing gas boiler.

Remember the radiators are usually sized to accommodate a 70oC water temperature. The heat pump in this case would most likely be operating at its maximum water temperature, so COP would be considerably less than nominal. In this case, CO2 and running costs may be worse than for a gas boiler and the heating system may not have the capacity to heat the property.

ELECTRIC BOOST

HEAT PUMPS AND HOT WATER PROVISION

Many air to water heat pumps incorporate electric heaters to restore the capacity to normal in extremely cold weather – which usually only occurs for a few days at a

COP is reduced when water is heated to a high temperature. It’s important to maintain a low water temperature consistent with the use of that water – possibly around

48oC. Remember, there is a Legionella risk if water is stored below 60oC. The risk of bacteria growth increases below that figure. It makes huge sense to increase the heat of the stored water above 60oC periodically, to kill the bacteria and reduce the dangers associated with storing hot water below that temperature.

Keeping the water temperature higher than the heat pump’s capability will risk the water always being heated by the immersion heater. When the tank cools, the immersion heater reheats the water before the temperature drops to a level where the heat pump cuts in. This needs to be avoided for obvious reasons.

In conclusion, when designing a heat pump system and looking at its heating circuit design, avoid systems that require high water temperatures. Keep the water flow temperatures as low as possible, use weather-dependent water temperature control if possible and programme electric heaters to run only in extreme weather conditions.

For the hot water circuit design – heat the water tank to the lowest temperature consistent with the property’s requirements for hot water. Programme the system to avoid the use of electric heating, apart from sterilising the tank to remove the dangers associated with the growth of Legionella bacteria. If the water temperature has to be increased beyond the capability of the heat pump, it is important to ensure that the water is always pre-heated by the ASHP before it can be boosted.

On 7th June 2017, renewable sources of energy generated more electricity than coal and gas in Great Britain for the first time. National Grid reported that on lunchtime that day, power from wind, solar, hydro and wood pellet burning supplied 50.7 percent of UK energy.

COVER STORY – CPD

What to do when customers won’t pay Peter Adkins of Emms Gilmore Liberson, stresses the importance of having a signed contract with your customer for every job you do.

• both parties’ names and addresses; • what work is to be included (and what is excluded); • the price (clearly stating whether it is inclusive/exclusive of VAT); • when payment is to be made; • when the work is to be completed by; • whether any payments are needed on account; and • who is to pay for parts.

Get the customer’s signature to the quote and this document will then form the contract between you.

Peter Adkins of Emms Gilmore Liberson Unfortunately, you may be familiar with this situation: You complete a job for a customer, the customer seems delighted so you send your invoice.

Then when you check your accounts a few weeks later, you realise that the invoice hasn’t been paid.

Your chasing is ignored, or worse still, results in complaints and outright refusals to pay. What appeared to be a simple and successful job is fast turning into a nightmare. Not only have you wasted your time, but you have probably paid out for parts and equipment as well. So what can you do to avoid this situation?

Unfortunately, whatever steps you take, there is always someone who is going to be difficult and try to avoid payment.

Contracts In this article, we look at the contract between you and your customer.

A contract can be verbal, but the saying that ‘a verbal contract isn’t worth the paper it is written on’ is often true sadly, as your recollection of events and agreements often differs wildly from the customer’s.

There is no excuse for not putting any quote in writing. Ensure you are clear on pricing and exactly what you are going to do for the customer. As a minimum this should include:

24

journal

|

It is worth having some pre-printed quote forms with your terms and conditions on them. If well written, these will prevent customers saying ‘yes, we signed that, but you later said we’d get a discount’, or ‘but you said you would include parts’ or ‘the work had to be finished by Christmas’. A little effort here can save problems later.

Apart from anything else, you will be seen to be operating a professional business.

the other should pay. So find out at the beginning who is responsible for payment and ensure they are one of the people who signs the contract.

Payments on account should be made when requested, if they are not, then a good set of terms of business will often enable you to stop work with no penalty.

Cooling off

If you are dealing with individuals (as opposed to businesses) there are some rules that apply as a result of consumer legislation.

These include quoting VAT inclusive figures and ‘cooling off ’ periods.

Very often, a job changes as it progresses.

If it does, produce an updated quote/list of extras with pricing etc and again ask the customer to sign to show their agreement before you do the work if possible. If they won’t sign then that is probably the first warning sign.

If you agree terms at the consumer’s own home (which is very often the case) then you are obliged to give a minimum 14 day cooling off period.

If you start work within that time, you may find the customer can cancel and you won’t be entitled to full (or any) payment. There are rules though which cover the situation where urgent repairs are needed e.g. burst pipes or where items are specially made. You must give details on how to cancel on your order form.

Check that whoever is signing the paperwork has the authority to do so and authorise payment. This is often the problem when dealing with companies.

Get the signatory’s full name and position.

Sometimes, landlords try and say it is a tenant’s responsibility, if so, the tenant should sign. On domestic jobs, similar problems can arise with one party saying

You are also obliged to provide customers with certain details about you/your business; your name, address, telephone number and limited company number are the bare minimum and extra information may well be needed. Your order forms can cover all of these to prevent you forgetting them.

I would also like to reflect on what has been an excellent year for the CIPHE and our members, who have enjoyed positive articles and exposure in the UK’s trade press. In 2017, over 160 CIPHE articles were published, covering subjects from water safety, to underfloor heating design, as well as interviews with our valued members who shared what makes them proud to be a professional.

We are grateful to the trade press for this continued support and look forward to sharing more knowledge and expertise with these well-read industry publications. What’s more, in 2018, we have another exciting programme of articles to come, including exclusive articles which you can read in the p&he Journal.

Continuing on the theme of the next generation of plumbing and heating professionals, I am eager to champion apprentices even more in 2018. Gathering the support of our members will be critical to achieving this objective. All of us need to be active in this aim if we are to make a difference and successfully promote how a career in our industry is one of the best and most rewarding professions any industrious and hardworking person could choose. As someone who has worked in our industry for the last 40 years and who started out on a technical apprenticeship, I can tell you how valuable this route into industry is.

EXTERNAL AFFAIRS GROUP

CLEANER, SMARTER, INSTALLER-LED HEATING Roger Webb, CIPHE Director of External Affairs says that the Government’s new 'Boiler Plus' standards gives installers flexibility when specifying a heating system for their customers.

I

n April, the Government is set to introduce new guidelines for gas boilers. In brief, the new ‘Boiler Plus’ standards are designed to give homeowners more choice regarding the way they heat their homes, resulting in greater control of their energy costs.

While boiler installation standards have been high in the UK since changes to the Building Regulations in 2005 made condensing boilers mandatory, the question of what to do with the thousands of older systems working away in domestic properties has long been debated − and quite often ignored.

For years, one of the mainstream heating industry’s frustrations was that the Government’s drive towards renewable heating technologies lacked realism. For a long time, renewables were presented as the only path to a greener future, even though these technologies weren’t feasible for most people.

IMPROVING EFFICIENCIES Having explored this route, it’s heartening to see the new regulations actually recognising that gas boilers are the 'here and now', and that improving the efficiencies of existing installations is a sensible idea. In that respect, the 'Boiler Plus' standards are somewhat of a breakthrough and I couldn’t have written the latest guidelines any better myself.

Needless to say, the CIPHE is fully supportive of this shift, especially as it’s not a 'one size fits all' approach. For example, the 'Boiler Plus' document doesn’t say that everyone has to have flue gas heat recovery or a particular type of control fitted. Instead, the document provides a range of options that can be used to improve the operating efficiency of any new or existing system.

INSTALLERS’ ROLE Crucially, plumbing and heating engineers will have a central role to play in helping select the best combination of technologies to meet the new regulations and their customer’s needs. At last, the Government appears to understand the role of the installer, with professionals being given appropriate levels of responsibility to use their discretion during the decision-making process.

After years of campaigning to reach this point, I think we’re making progress.

STAMPING OUT NON-COMPLIANT PRODUCTS For those who attended last year’s Bathroom Manufacturer’s Association (BMA) conference, the negative impact of non-compliant products was covered extensively. It is something that Yvonne Orgill, CEO at the BMA and voluntary member of the CIPHE External Affairs Group at the CIPHE, wants members never to forget.

N

on-compliant products cause many problems that can ultimately put consumers at risk. This is why failure to comply can lead to steep fines and in some instances, imprisonment.

Professionals can make right choices by doing their research and checking UK/EU law. One message to take into 2018, is to ensure that if there is a problem, you can trace the materials back through the supply chain to the manufacturer. This will protect you and your customer.

Don’t be afraid to ask questions about CE markings and to ask for documentation such as the EC Declaration of Performance. Your livelihood and the lives of others could be at risk if you don’t.

HAPPY NEW MEMBERSHIP YEAR Paul Massey, Chairman of the CIPHE’s Industrial Associates (IA) Development Group, says that although the Christmas festivities are behind us now, the Institute had much to celebrate as 2017 came to a close.

F

ollowing the launch of the ‘Proud to be a Professional’ campaign two years ago, and a period of concentrated activity to raise the CIPHE’s profile, membership is happily on the increase.

Looking back, the arrival of Paul Harmer as Technical Director and Tim Sainty as Membership Director, were both key appointments for the CIPHE. Since 2016, Paul has concentrated on developing the Institute’s technical and training activities, with the exciting introduction of a series of new 3D Virtual Reality (techtalkVR) continuing professional development (techtalkCPD) resources for 2018. He has been supported in this venture by individual members and manufacturers alike.

MEMBERSHIP SERVICES Tim’s focus on developing membership services and resources has also played a vital role in keeping the Institute relevant to the needs of those working in the plumbing and heating community today.

Beyond this, the backing that the Institute continues to receive from its Industrial Associate (IA) members is tremendously important.

Since starting to drive membership in early 2016, attendance at our quarterly IA events has increased from meeting to meeting. The fact that leading names in the plumbing, heating and bathroom industries are so willing to join together to ensure that quality installations are the order of the day is good news indeed.

OPPORTUNITIES As we embrace the opportunities that come with a brand-new year, the CIPHE’s focus remains firmly on raising standards through continued learning and the promotion of best practice, with a view to protecting consumers at all times.

My colleague,Tim Sainty, has said it before but I’ll say it again, the Institute is proud to promote professionalism and best practice at every age and every stage of a career in plumbing and heating, and this year will be no exception.

A LEAD-FREE FUTURE WITH PLASTICS Dr Simon Reddy, Master Plumber

Dr Simon Reddy discusses the health risks associated with legacy plumbing and the consequent potential lead contamination of water supplies.

I

have worked on the tools as a domestic plumber for over 30 years and, for much of this time, I have also taught plumbing and researched training in further education. As the recipient of the World Plumbing Council scholarship in 2016, I visited Hong Kong to investigate their plumbing and training system. Following the visit, I wrote a report in 2017 about my findings. To see the report please visit https://tinyurl.com/ycj7njov In this article, some aspects of that 2017 report are discussed, particularly those that highlight a risk to health in the United Kingdom, owing to lead poisoning from legacy plumbing (imperial-sized copper installed between 1950 and 1986, which is likely to be jointed with solder that contains lead).

In the Hong Kong context, independent tests showed higher levels of lead in the water supply (side) in public housing estates that had copper plumbing systems. Lead is toxic to many different organs in the human body, its toxicity can lead to neurodevelopmental effects, anaemia, high blood pressure, gastrointestinal symptoms, impaired renal function, neurological impairment, impaired fertility and adverse pregnancy outcomes.

Infants, young children, pregnant women and women who breast feed are particularly at risk from the adverse effects of lead.

The Independent Hong Kong Report (2015: 16) on the matter, revealed that solder materials seeped into the pipe. This was due to poor workmanship, for instance by overheating the pipe during welding for an extended period of time and/or applying excessive solder: This incident immediately drew my attention to the English context, where it is apparently legal to join new plumbing to older systems which may contain copper with lead solder joints. This may constitute a risk to public health.

CASE STUDY A case in 2013 investigated a recently-built luxury apartment block where tap water samples contained more than 12 times the permitted amount of lead – owing to five or six joints (containing lead) on short lengths of distribution pipe entering each apartment.

The Water Research Centre highlighted the possibility that, owing to galvanic action between copper and lead solder, “combinations of lead and copper pipework may actually lead to higher concentrations of lead in drinking water than lead pipes alone” (Potter, 1997). So, almost counterintuitively, combining metals in this way may result in more lead content in the water than using lead pipes.

Previous warnings given by WaterSafe have focused on lead piping. However, more recently, they have warned that older copper pipes may also contain harmful lead – WaterSafe also warn that children are particularly at risk.

PLASTIC PIPES INSIDE BUILDINGS CONFERENCE Brass fittings and drinking water taps may also contain lead. In the United States, the Reduction of Lead in Drinking Water Act 2014

POOR WORKMANSHIP Hong Kong only introduced regulations for lead-free solder in 2006 – the UK in 1986.

reduced the lead content allowed in water systems and plumbing products. The act changed the definition of “lead-free” from not more than eight percent lead content, to not more than a weighted average of 0.25 percent.

The problems of legacy plumbing are truly worldwide. Test results, which were published in 2017 in British Columbia, Canada, revealed that lead levels exceeded drinking water guidelines (some by wide margins) in over a quarter of the 15,000 tests on about 10,000 drinking sources in schools.

The important issues of lead in the water and legacy plumbing were discussed at the international ‘Plastic pipes inside buildings conference’, held in Cologne, Germany, in October 2017. It was suggested at the conference that plumbing qualifications in the UK had been heavily influenced by the use of steel and copper pipework – to the detriment of apprentices learning more about plastic products. Oliver Bannert (2017) of PipeLife, made a convincing case for plastics being more environmentally friendly than metals over a life cycle assessment i.e. from cradle to grave.

UK QUALIFICATIONS SHOULD INCLUDE MORE MATERIALS The environmental case for plastics is clear when you consider the high amount of energy required to produce steel pipes and

Oliver Bannert’s (2017) environmental advantages of plastics over metals for plumbing

to recycle the metal at the end of its lifecycle.

The day before the conference in Cologne, I was invited to the Aquatherm plastics factory in Attendorn, Germany. The walk around the factory and hands-on training in the technical workshops convinced me that UK qualifications need much more emphasis on a diverse range of

materials, and especially those that have worthy environmental credentials like plastics. Getting to see and work with the Aquatherm polypropylene products was a good experience, and one which helped me understand the benefits of plastics. The pipes were light-weight, clean, and easy to cut, joint and fabricate: Aquatherm states that their polypropylene products, including the brass parts, were lead-free (now standard in Germany). It became apparent that the prefabrication of large diameter manifolds and headers (up to 650mm) offered a premium product that could be made in the factory and assembled quickly on site. The state-of-the-art manufacturing, production and recycling processes resulted in little waste, and arguably, lower carbon dioxide emissions than shipping excess materials for on-site fabrication.

As carbon dioxide is considered a key cause of global warming, plastics are worth serious consideration for the future. This is especially the case if we want to move towards zero-lead plumbing systems.

The CIPHE appreciates the support provided by the Hong Kong Branch, which helped make Dr Reddy's visit so successful.
