HEAT PUMPS

The low carbon heating combo
Low carbon heat pumps combined with underfloor heating could be one of the solutions to energy efficient heating when gas boilers are phased out in 2025 T
he unfortunate truth is that gas boilers will be phased out and banned from use in new build homes. 2025 is earmarked as the ban start date as the government ramps up its activity to build a low carbon future that is environmentally friendly and sustainable. Among the earmarked products to replace gas boilers are low carbon heat pumps – such as ground source heat pumps (GSHPs) and air source heat pumps (ASHPs) – which are powered by electricity. As heat pumps are typically at their most efficient when heating water up to around 35-40°C, this means they won’t be suitable for use with traditional convection radiators, which need heat to be at 70-80°C to work effectively.
This leaves underfloor heating (UFH) as the most viable heating option when
gas boilers phase out. With wet UFH, the system only needs to run between 35-40°C to heat up the water in the pipework and transfer the heat into the room. Making it a compatible heating method to work with GSHP and ASHP. Not only that, UFH also helps create a comfortable and aesthetically pleasing home, because the pipework is hidden from sight, hence creating extra interior space. With UFH projects likely to gain popularity, a number of companies such as RWC offer a suite of UFH solutions to complete new build or retro-fit installations. These come with free estimation and CAD design service to assist installers with selecting the best system for their project, sourcing the right quantity of material and helping them make installation efficient.
