for this misconception is that traditionally, manufacturers supplied ‘headline’ efficiencies for their products, figures achieved in ideal laboratory conditions rather than in real life scenarios. This has, at times, contributed to an energy performance gap where the actual energy usage of a building could double the anticipated consumption. The efficiencies achievable by GAHPs – or indeed any heating technology – are dependent on a number of factors, amongst which the flow/return temperatures. For this reason, we at Remeha have compiled performance tables listing the achievable gas utilisation efficiency (GUE) of our own Fusion GAHP


Heating efficiency (GUE) @50⁰C water delivery temperature


148% 153% 155%


Heating efficiency (GUE) @65⁰C water delivery temperature


119% 127% 131%


range at different ambient temperatures and at a variety of flow/return temperatures to enable more accurate calculations of energy use and savings.


Let’s assume that the building where the


GAHP is to be installed is in Birmingham. What level of efficiencies can we realistically expect the GAHP to achieve? By cross checking the average temperature supplied by the Met office for the Midlands region with our own proven performance data, we can calculate the energy performance. As the data illustrates, even at the lower temperatures, the GAHPs continue to deliver impressively high efficiency heating. For the building operator, this means


lower fuel bills and a reduction in carbon emissions of up to 40% compared with traditional heating equipment.


Reliable and highly efficient,


GAHPs provide a financially and environmentally sustainable solution to low carbon, low NOx heating and hot water provision with rapid return on investment. This high performance technology, which is fully compliant with the Ecodesign requirements of the Energy-related Products Directive, offers a practical, affordable means to


achieving greater energy efficiency, meeting the carbon requirements of Part L of Building Regulations for new build developments and supporting the decarbonisation of heating in our existing buildings. As we look to reduce our energy use and our carbon footprint, it’s good to know that with GAHPs, the technology is already here to effect positive change.

ENERGY SAVING WATER SOURCE HEAT PUMP SYSTEM REVOLUTIONISES TATTLETON ESTATE


B


aystar Energy Efficient Systems hosted a seminar recently on the energy savings that water source heat pump systems can offer large property and estate


owners as well as businesses. Held at Tattleton Estate in Horsham, owner Chris


Stone confirmed how the installation of a water source heat pump system has already saved him £000s and reduced his reliance on fossil fuels, set to continue over the planned three to five payback period. Guest speakers at the event were Emma Griffiths, heat energy specialist from the National Trust, who gave an overview of how water source and


biomass systems are being


successfully used at a variety of Trust properties, and Robin Curtis, a Department of Energy and Climate Change (DECC) geoscientist, who talked through various energy systems and shared


his views of sustainable energy for the future. Baystar director Jonny Starmer showed exactly how the water source heat pump system project worked at Tattleton House and guests were then given a tour of the grounds showing where the installation is sited, and the pump rooms. Chris Stone said, “We built Tattleton from scratch, having bought the land, and wanted to be as sustainable in terms of energy as possible. With water heating, there is zero heat loss and no smells or emissions, and the savings show what a good investment the water source heat pump system is. I’d recommend it to anyone with land, large properties like castles, colleges or historic buildings.” The seminar will help management in industry, large property owners and businesses with a body of water on their land understand how energy innovation - and heat pumps in particular - can deliver low energy costs, greater comfort and better buildings.
