First Choice Heat Pump Solution For New Build Housing

The new LG R32 Monobloc range has already had a massive impact on the residential heat pump market in the UK. Its new Monobloc S version of the unit which combines the indoor and outdoor features in one module is connected by only water piping, eliminating the need for refrigerant piping, making this heat pump an installer’s dream when it comes to ease of installation.

Hydronic components like the improved plate heat exchanger, the expansion tank, water pump, flow sensor, pressure sensor, air vent valve and safety valve are all built in - inside the outdoor unit – preinstalled and ready to run. And the R32 Monobloc ‘S’ provides excellent heating performance especially at low ambient temperatures whilst lowering its carbon emissions even more with the use of R32.

The original version was extremely quiet, but this new ‘S’ version is even quieter and up to 9kW units can be installed at the minimum of 4 metres away, and up to 16kW units - up to 5 metres away from neighbouring houses complying with international noise regulations.

Installers will love the new Monobloc ‘S’ – the all-inone concept and reduced weight of the unit makes for easier and quicker installations. The new version requires lower amounts of refrigerant compared to the existing model – 16.7% less in fact – reducing emissions and lessening its environmental impact still further. The new version features LG’s revolutionary R1 Compressor technology which offers advanced efficiency, reliability and operational range due in part to the enhanced tilting motion of the scroll. It offers enhanced operational range – up to 135Hz, a shaft-through structure and support at both ends of the shaft which ensures higher durability and offers bottom compression and simple structure that offers lower noise and vibration, less weight and superior reliability. The Health and Safety Executive’s HSG76 advises on a number of areas that need to be taken into account when planning the layout of a site so that ‘…pedestrians and vehicles can circulate safely. Where vehicles and pedestrians use the same traffic route, there should be adequate separation between them’.

This involves the installation of clear signage and floor markings, which are crucial to the safe and efficient movement of people, vehicles and machinery around the industrial workspace. HSG76 also recommends combining this clearly discernible signage with guardrails and pedestrian handrails used to create clear segregation and traffic routes.

Racking and storage is another area where incremental gains in safety can be achieved in a relatively straightforward and cost-effective manner. The application of clip-on protection to rack ends and any sharp edges of units will for example, protect people, vehicles and the units themselves from impact and collision damage.

Careful consideration should also be given to choosing the right products supplier. First and foremost, it is critical that they must offer products appropriate for the project. This might seem somewhat obvious, but it is not uncommon for some safety products to look good on paper only to lack the necessary performance characteristics that make them suitable for the required application.

Within the outdoor unit the new version of the LG Monobloc offers a new compressor noise shield, a new Black Fin coated heat exchanger, a new water flow sensor and a new water pressure sensor. There is an option to include a 3kW or 6kW electric back up heater. The unit comes with a Seasonal Coefficient of Performance of up to 4.67 (Average climate/Low temperature application) and a A+++ rating. The COP rises to 4.9 (Outdoor air 7°C/Leaving water temperature 35°C) and can deliver leaving water temperature of 65°C if required.

LG has launched a New Build Design Service, to assist new build developers when specifying heat pumps into new homes.

This new service is for developments of 6 or more plots and will provide full designs for plumbing and heating layouts along with equipment schedules that specify the heat pump required, radiator or underfloor manifold heating positions, pipework type and length and controls to ensure that the system which is specified will provide the necessary heating and hot water solution for any house archetype. Furthermore, LG also offers a unique service for CFD (Computational Fluid Dynamics) analysis, determining the optimal location and performance simulation of the outdoor units.

This new service comes hot on the heels of the recent launch of the latest version of the LG Therma V Monobloc air to water heat pump – the Therma V Monobloc S - which builds on the success of the original Monobloc with a number of important new features and improved performance criteria.

The new Monobloc S range further supports LG’s Split, Hydro Split and High Temperature Split Heat Pumps which all benefit from the company’s in-house revolutionary R1 Compressor technology. Homeowners can further benefit through the LG’s ThinQ platform, which the company integrates in to products ranging from TV’s to refrigerators and enables a total smart home control for the consumer with the purchase of the LG Wifi Modem and by downloading the ThinQ app.

DOMUS VENTILATION MVHR SYSTEMS PROVE IDEAL RETROFIT SOLUTION FOR LONDON RENTAL DEVELOPMENT

Domus Ventilation’s HRXE-HERA® Mechanical Ventilation with Heat Recovery (MVHR) systems have been specified for the be:here Hayes build-to-rent residential development in West London. When the building was designed, Domus Ventilation’s Silavent MVHR ceiling mounted units were installed. These are now being gradually replaced with Domus Ventilation’s latest MVHR model, HRXE-HERA®. As a retrofit solution, HRXE-HERA® has proven ideal for be:here Hayes as they readily use the existing Domus ducting.

Domus Ventilation’s HRXE-HERA® MVHR have proved an ideal solution. It filters and pre-warms fresh air drawn into the apartment using the heat from waste stale air extracted from the kitchen and bathroom using a heat exchanger. It’s advanced heat exchange proficiency enables up to 95% of waste heat to be recovered. It comes with 100% thermal (summer) bypass which automatically activates when the air temperature reaches a pre-set level, allowing in cooler, fresh, filtered air without warming it through the heat exchanger. The smart design of the HRXE means there is no reduction in airflow when operating in bypass mode. www.domusventilation.co.uk

SMOKE EXTRACTION SOLUTION

Fire safety remains a top priority for all involved in the construction industry, with many manufacturers offering many solutions. GEZE, a leading manufacturer of door and window control systems, offers one more, which they believe is a unique solution for smoke extraction systems in the market place.

The RWA K 600 retractable arm drive can be fitted to emergency exits on escape routes and in the event of a fire it can be used as a fresh air supply which when the fire alarm is sounded the door opens automatically allowing a large amount of air to flow into the building and forcing smoke out. The powerful drive with high torque opens a door to 90 in less than 60 seconds. Yet the door remains readily accessible due to the freely positioned activation of the lever by means of a pressure roller.

The RWA K 600 is perfect for use in supply air systems where large opening angles are required, it is suitable for single and double leaf smoke and heat extraction fresh air doors and can be installed on both the hinge or opposite hinge side. Said Andy Iredale, National Sales Manager for Automatic Doors and Window Control, “The RWA K 600 is a unique solution in the extraction of smoke from a building in the case of fire. It’s suitability for use in a variety of situations makes it perfect for use on escape routes.” www.geze.co.uk
