Heat Pump News Clean technology for care homes from ICS


BARCHESTER Healthcare has switched to new heat pump technology in one of its properties. It has already proved a 50% reduction in carbon emissions and is now rolling out the successful strategy across the rest of its non-mains gas homes. ICS Cool Energy supplied the heat pumps to the healthcare industry system designer and installer, Renewable Heat Services (RHS), to install AWHT0202 high temperature heat pumps at Barchester’s Westergate House Care Home in West Sussex. The Grade II listed building had two separate boiler rooms – one for each of the buildings. Five ageing oil boilers which were inefficient and expensive to maintain were being used.


Renewable Heat Services closed one of the existing boiler rooms and created a new centralised energy production centre, installing two 100kW state-of-the-art high output temperature air source heat pumps from ICS Cool Energy. This provided a renewable energy solution to help reduce carbon emissions and running costs. The high temperature units extract heat from the surrounding air and produce output water temperatures as high as 65°C in ambient air temperatures as low as -12°C. The heat pumps continue to operate efficiently in ambient air temperatures as low as -20°C. These high efficiency heat pumps deliver much greater


energy-efficiency, averaging around 300%, while ageing conventional oil or gas boilers have efficiencies of around 65%. The heat pumps are a cost- effective and simple option and offer high levels of reliability and low maintenance costs. The RHS design claims to extend the life of the key components from 15 years to over 20 years.


Thanks to two independent circuits per machine, the units provide a high level of redundancy – essential when keeping vulnerable residents warm 24/7, 365 days a year. Martin Palmer, owner of Renewable Heat Services said: “Since early 2009, we have evolved a design specification that meets the challenging


legal requirements for ensuring constant and reliable internal minimum temperature levels for care homes, and we have combined this with very large reductions in carbon emissions and costs.


“The availability of the technology-leading air source heat pumps from ICS Cool Energy has enabled us to evolve this successful system design. So far we have installed these heat pumps on some 30 sites.” Director of property services at Barchester Healthcare, Bill Wilson, said: “The solution offered by RHS with ICS Cool Energy fitted exactly our need to move away from fossil fuels to reliable, clean modern technology.”


Next generation wall-mounted air conditioner


DAIKIN EUROPE is set to launch the new Daikin Emura wall- mounted air conditioning range in spring this year. The company says that the range was designed in Europe to satisfy a uniquely European architectural aesthetic. Available in silver and anthracite or pure matt white, Emura is aerodynamically designed to create an incredibly thin profile, making a modern design statement on any wall. The unit can be controlled remotely through Wi-Fi, even away from the home. An intelligent eye sensor and 3D air flow save energy when the room is empty and direct air flow to avoid cold draughts, reducing power consumption dramatically, compared with typical air conditioning units. Innovative compressor technology maximises efficiency, especially in part load operation, optimising the year-round performance, further enhanced by delivering much lower losses in standby mode. As a result, Emura reaches a high SEER of up to A+++ and SCOP up to A++.


Optimal energy efficiency is combined with minimal sound levels as low as 19dBA. With its full range of 2kW, 2.5kW, 3.5kW and 5kW models, the suitable size of unit can be selected for any application.


The unit can be programmed on a weekly basis, with different settings defined for each day of the week, so occupants can tailor performance to their own requirements. For greater flexibility, Emura can be controlled from a distance using an app available for both Apple and android platforms. This ‘plug and play’ extra Wi-Fi device has an intuitive interface, making it even easier to control the unit both inside and outside the home.
