RINNAI HOT WATER ON DEMAND - FUEL, ENERGY, ENVIRONMENT AND FINANCE EFFICIENT – AND NOW EASY TO CHOOSE

Rinnai – makers of units delivering limitless, on demand supplies of hot water – are offering end-users an easy-to-choose facility via online interface.

The end-user simply visits the www.rinnaiuk.com website for instant assistance on choosing the right products to deliver fuel, energy and environmentally efficient hot water, reliably and constantly.

Says Chris Goggin, “Whatever your industry we have innovative products and systems that give your site or sites limitless supplies of temperature-controlled hot water which are designed with the environment in mind, with low emission technology and high efficiencies, as well as a host of other great features, as well as costing you significantly less than any other mode of hot water supply.”

We recognise that every application is unique and that choosing the right product can be a little daunting so we invite end-users to visit our website www.rinnaiuk. com and find the ‘Help Me Choose’ facility and we will do everything else from there,” adds Mr Goggin.

Rinnai recently completed the installation of 2 x HDC1500i continuous flow hot water heating units at a busy laundrette serving businesses and the public in Stafford. Rinnai products were chosen on the recommendation of another laundrette owner, in Lancashire, who praised the efficiency and major cost savings because of switching to cascaded continuous flow hot water units as they guarantee almost unlimited supplies of hot water at peak demand whilst savings on fuel costs.

Word of mouth is the best possible marketing and a site survey was duly arranged and completed to confirm the best solution in controlling operational costs and efficiencies. The existing system was a heated stored water system – this meant that the site was paying to heat water it was not instantly using. It was clear from the site survey that Rinnai units configured to maximise both space and energy efficiency – and critically – the system’s reliability – would yield seriously large cost savings to the owner.

Given that the Rinnai units were being wall mounted and externally flued, this gave extra storage space to the premises as there was no need for a dedicated plant room.

Comments Ray Gallimore, proprietor of the Weston Road

Launderette, “The old storage system had become completely impractical, inefficient and needlessly expensive to run.

“For example, the washers tend to be used sporadically. During a busy weekend there could be a demand for eight to ten people battling to use the machines at once, during the week there might be one or two. That meant we had to store a decent volume of hot water ‘just in case’ in the form of a storage water heater. Needless to say, keeping the stored volume at optimum temperature 24/7 was often wasted energy, a really bad, expensive idea all round.”

Clearly the site needed to change the system to one that could cater for these fluctuations without running up huge energy bills and the solution wasn’t hard to find.

“I was made aware of Infinity water heaters installed in similar applications to mine and in general their experiences with their products and their personnel, such as the local Rinnai sales consultant, were consistently positive and professional.”

“The beauty of working with Rinnai is the service they offer. We presented the project to Rinnai’s Technical Sales team who came up with the design, configured the sizes of unit required and delivered the system complete and to a very tight timescale – this was key as the existing water heater had developed a leak and I was extremely mindful that the business had to remain operational to satisfy local demand. We are very happy with Rinnai and will be spreading the word,” adds Ray Gallimore.

Now two HDC1500i internal mounted water heaters with secondary circulation provide hot water for 12 commercial machines, plus a sink and a wash hand basin.

“The Rinnai system has resulted in an energy reduction and gas saving due to higher efficiencies and because we are no longer maintaining large amounts of stored hot water. It’s not rocket science to work that out!”

“In terms of gas usage running costs compared to the old wasteful storage system, our bills have virtually been halved since the Rinnai system went live five months ago which is absolutely tremendous,” says Gallimore.

Rinnai’s heavy-duty condensing range uses two heat exchangers to capture residual heat from flue gases to pre-heat incoming water, with the HDC1500i turning in 105% net efficiencies*. These figures add up to considerable on-going energy savings when compared with traditional gas fired stored water systems.

With a Rinnai condensing unit, temperature is regulated to within +/-1ºC via ‘smart’ internal controls without any variation of temperature at the outlet even when water is drawn off elsewhere. All models have full electronic ignition, no pilot light and operate on demand only, so there is no gas consumption when the unit is idle.

The units are easily configured in a manifold arrangement, ensuring there will never be a shortfall of instant hot water whatever the demand.

Rinnai, the UK’s leading manufacturer of the ErP A-rated Infinity range of continuous flow condensing gas-fired water heaters, supplies the best energy efficient range of low-NOx water heating units currently on the market.

Advanced condensing heat exchangers combined with innovative burner technology ensures that every cubic metre of gas is used to the maximum on HDC 1500i.

Legionella proliferation is answered by Rinnai: the company has developed additional ‘SMART’ controls for secondary return DHW systems in the form of an advanced temperature control system which allows for safe running of water at 42°C core temperature during the day and 60°C at a time when the building is closed. By the time the building reopens, core temperature is 42°C for safe use.

Another Rinnai innovation addresses an age-old industry problem with hot water delivery - lime scale build-up. The company’s integrated scale control system is an innovative solution and comes in the form of an LC (lime check) code on the display of the controller.

Almost all water-fed appliances, including plate heat exchangers, boilers and water heaters will accumulate scale deposits when used within hard water areas over time. Lime scale consists of calcium carbonate (calcite) with lesser amounts of other calcium salts such as the sulphate. Sometimes lime scale deposits contain corrosion debris and this scale build-up can affect the water heaters by reducing their efficiency and overall performance.

Ultimately, ongoing use with hard water may shorten the lifespan of conventional water heating appliances and systems. To safeguard against this Rinnai units continually self-monitor for lime scale deposits around the heat exchanger. If a lime scale build up has being identified, a message is sent to the built-in interface panel on the front of the appliance. The message is displayed as ‘LC’, which alerts the end user that it is time to call a Rinnai service agent to perform a lime scale flush to clear the potentially harmful deposits. This avoids and eliminates the adverse effects associated with lime scale build up, including lower energy efficiencies and rapid product de-generation.

Rinnai’s HDC range offers condensing technology with up to 107% gross efficiency, ultra-lowNOx of less than 20 ppm, a widely expansive modulation range of 54kW-4kW and high flow rates of 37/ltr/min. Add to these benefits are the peace of mind of an extended warranty, a top A-rating exceeding the demands of ecolabelling legislation, the flexibility of external wall mounting and delivery to site with all relevant accessories and the knowledge that the HDC range is future-proofed against future regulatory and legislative changes.

Gilberts louvres help double feed mill production capacity, safely

The safety of feed processing at the largest UK farmer-owned dairy co-operative is being protected via a patented ventilation design.

United Feeds, part of the Dale Farm co-operative, has extended its mill at Dungannon, in Northern Ireland, to double its capacity. Central to the development, built by McKelvey Construction, is a new intake building to include eight rax material bins, plus an additional loading point and weighbridge, with 10 additional finished product bins for the company’s bespoke nutritional solutions for ruminant animals.

“It was crucial the ventilation was optimised, to meet the stringent health & safety, and fire, requirements necessary in such facilities, particularly above the weighbridge area,” explained

Daniel McCrory of McKelvey

Construction. “Health & safety is paramount to United Feeds, and the new building faced essential fire safety requirements. We had to provide good ventilation because of the potential for dust, yet avoid any potential risk of water ingress as this could damage the stored feed.”

Optimum ventilation to the weighbridge and finished product bins to maintain safety inside is achieved via threesided, 33m long louvre screens on each of the two silo towers, created from Gilberts’ patented WH75 series high performance ventilation louvres.

Each louvre façade was constructed on site, with each blade having to be cut to fit precisely to suit the raking head profile that graduated from 1.5m to 2.5m, and corners mitred for a flush fit. Added Daniel McRory, “The patented design of Gilberts’ WH75 louvres gave us the ventilation and weather protection performance we needed, in a system that could be tailored to the project’s precise tolerances.”

Gilberts’ WH75 Series of ventilation louvres deliver a Class A weather rating, with low pressure loss and at least 50% free airflow area. The innovative design of the louvre blades features an integrated channel to provide optimum efficiency in removal of water from the blade face, and subsequent discharge away from any façade opening.

The WH75 louvres are just part of Gilberts’ range of louvres, grilles and diffusers that have established it as Britain’s leading independent air movement specialist, with solutions for mechanical and natural ventilation in commercial applications.

Founded over five decades ago, Gilberts Blackpool is unique in its ability to develop components- whether ‘mainstream’ or bespoke - entirely in-house, from initial design through tooling, production, testing and supply, at its 95,000 ft2 manufacturing facility. Its state of the art test centre, designed and built in-house, is one of the most technically advanced in the country.

Waterloo brings a breath of fresh air to Studley Castle

Waterloo Air Products Plc’s grilles, air valves and diffusers have been used extensively throughout the magnificently renovated Studley Castle, successfully creating the perfect environment at Warner Leisure’s new landmark hotel.

Set in 28 acres of Warwickshire countryside, this Grade II-listed, Gothic Revival style castle was originally designed by Samuel Beazley, the leading London theatre architect, as a family home.

In its 180-year history, it has been used as an agricultural college for women, the training ground for the Women’s Land Army during both world wars, and, most recently as a hotel.

Since being bought by Warner in 2016, Studley Castle has undergone a three-year, £50m restoration and development programme to restore it to its former splendour.

The original building has been sensitively refurbished for modern use, and a spa created in the former Stables.

The investment has also resulted in an entirely new hotel wing with 210 bedrooms, a cinema, two restaurants, bars, lounges and a cabaret venue. The hotel is air-conditioned throughout.

With comfort a top priority in this luxury hotel, ensuring optimum air quality was an essential requirement for Warner. But creating a unified hotel aesthetic was equally key.

Waterloo was specified as the sole supplier due to its reputation for quality product operation and design.

Working with M&E Service Contractors LJJ Ltd, Waterloo was tasked with supplying a combination of grilles, air valves and circular diffusers that would deliver the required high performance while blending seamlessly into the décor.

Stylistically, Studley Castle mixes its heritage past with an individual whimsical charm. In the foyer, there are nods to Alice in Wonderland and unicorns, while the cabaret and lounge areas each follow a unique design theme which the air terminal devices needed to complement.

Gerry McNally, project

manager at LJJ explained: “The architect and client had a very clear vision of what they wanted to achieve with this building, and it was our job to combine aesthetics with functionality to make their vision a reality.

“Waterloo took on board all the requirements and worked closely with us, attending

client meetings and paying regular site visits to review the project.”

Waterloo’s solution was a series of bespoke-designed grilles produced in six different colours. Each grille successfully achieved a ceiling layout that met all the particular aesthetic requirements of each room while operating to the highest standard for maximum comfort levels.

The maintenance aspect was another area that benefited from Waterloo’s expert technical and product support. To enable easier future maintenance of the air conditioning, Waterloo provided a dual-purpose combined air grille and access grille.

The grilles were spring loaded to enable them to be pulled down without tools, making them maintenance-friendly while maintaining the aesthetic feel of the building.

Gerry added: “This was a challenging project that required full collaboration from our suppliers. The service we received from Waterloo throughout was fantastic, as was the delivery. The end result is outstanding – and we couldn’t have done it without their support.”

The 14th property in shortbreak specialist Warner Leisure’s portfolio, Studley Castle is now the group’s flagship hotel.

Waterloo is proud to have played a part in its reinvention, fusing aesthetics and functionality to breathe fresh air into this exciting new development.

Petzl Helmets, Choosing Excellence

Essential for working at height, helmets provide efficient and effective impact protection in the event of a fall or from a falling object.

For Petzl, head protection represents more than simply wearing a helmet. We work tirelessly so that professionals have comfortable helmets that fit well and address the needs of all professionals in any situation. Our VERTEX and STRATO range of helmets are also available in vented or hi-viz versions.

When you have to wear a helmet all day long, perfect comfort and head fit are essential. This is why our professional helmets all feature the CENTERFIT headband adjustment system for perfect centering, and the FLIP&FIT system that immediately positions the headband in a low position for a secure fit. In addition, the headband folds into the shell for easy storage and transport.

Professionals who work at height or on the ground understand that head protection goes well beyond simply wearing a helmet. This is why Petzl has developed a full line of modular accessories for you to customize your helmet for the specific needs of the task at hand. Eye shields, face shields, nametag holders, neck protectors, headlamps, etc.

These accessories are now compatible with all VERTEX and STRATO helmets (VENT, HI-VIZ…) and take just a few seconds to install.

With the DUAL chinstrap feature, Petzl goes a step further: the clip has two positions for two different uses, allowing workers to modify chinstrap resistance according to the needs of each work environment: work at height (EN 12492) and on the ground (EN 397).

More information and advice on Petzl helmets can be found here.

Wellbeing in the construction industry

Mental health and wellbeing are no longer corporate buzzwords. Businesses within the construction industry have a real duty to support the wellbeing of its staff. Not only does this foster a strong workplace culture, but can have a positive impact on business too. Happy staff are more productive, and more likely to stay loyal to their company (and, in turn, its customers).

Construction site workers are three times more likely to die by suicide when compared to the average male in the UK, showing the desperate need for more support in the industry. Construction professionals are exposed to long hours, demanding workloads, working away from home, financial uncertainty and physical strain. Some professionals feel high levels of responsibility and a general lack of support, which leads to mental health problems such as anxiety and depression. The environment is also still primarily male, perhaps reinforcing unhelpful male stereotypes leading to some being unwilling or feeling unable to talk about their struggles.

According to UK Construction Week stats, over half of construction professionals have suffered from mental health problems… and they believe their employer could do more to support them.

Though stats show that absenteeism is decreasing, presenteeism and leaveism is on the rise. This means that employees are coming to work ill, or using their annual leave entitlement when they’re working instead or should be off sick. For professionals in the construction industry this could be particularly dangerous, as mistakes can easily be made if someone isn’t fit to be at work. Employers should make sure that all members of staff, suppliers and contractors are able to take the time off they need to recover.

Stats from the Office for National Statistics show that employees take over for days off due to sickness each year, with many of these days off related to mental health problems.

Employers should prioritise improving wellbeing within the workplace. Healthy and happy employees are less likely to take time off work unless they are genuinely ill, in which case they should be entitled to rest and return to work when they are ready. In the long run, implementing a wellbeing programme can produce high ROI thanks to increased productivity, less sick days and higher employee retention rate. Stats show that over a third of construction workers have taken time off work due to mental health problems. If this number can be reduced thanks to an effective wellbeing programme, this can ultimately save businesses money. We Are Wellbeing is a strategic wellbeing partner that helps businesses develop a positive company culture where its employees can thrive. Part of the Romero Group, the complementary service offers businesses assistance developing and actioning a wellbeing programme. For those in the construction industry, this can help support staff through periods of stress. Where responsibility is high, hours are long and the pressure is on it’s important to be able to manage stress effectively and a wellbeing programme can help aid this. Physical health and safety is prioritised in the industry, and it’s high time employers now put the focus on mental health too. Nurturing an open-minded culture where team members are able to open up and talk about their struggles is just the start of building better wellbeing within the industry.
