HEATING, VENTILATION & SERVICES
Pump up the volume
Donna-Marie Evans of LG Electronics explains why heat pumps are the right choice for UK housebuilders and homeowners to comply with the Future Homes Standard, and tackles some myths
W
ith recent announcements from the Government about the decarbonisation of heating in
the UK, the arrival of the Future Homes Standard and the decision by the Government that after 2025 no new build homes can have fossil fuel heating systems, the spotlight has been trained on proven renewable technologies to provide our heating and hot water here in the UK. Heat pumps have seen a huge take up in northern Europe, Scandinavia and Canada – all of which experience far worse winters and lower temperatures than we do in the UK – and now it seems inevitable they will at last grow in importance here too. Air to water (AWHP) systems (‘monoblocs’ or ‘splits’) present a variety of energy-saving options for a home’s heating and hot water. By replacing a traditional gas, oil, or solid fuel system, or specified as the means of providing heating and hot water in a new property,

an AWHP can significantly reduce carbon emissions and energy usage. These devices’ absorption of natural energy from external air makes them consume less energy than conventional heating systems. They can operate successfully at low temperatures – as low as -7°C – and it’s very rare for temperatures in most of the UK to drop that low. We’re looking at between three and four times the energy efficiency you can obtain from the most efficient condensing gas boiler. The terms ‘split’ and ‘monobloc’ refer to how the system is required to be set up in a home. A Monobloc is a bit like a combi boiler and is literally a ‘single block’ system, where the heat pump has all of its components – apart from the hot water cylinder which is installed inside the property – located inside a heat pump unit situated outside the home. Because a monobloc does not require someone with F Gas qualifications to get involved in the use of refrigerants, they are an excellent
