Electricity powered heat pumps can be used to convert low grade heat from the environment to heat homes very efficiently and the UK government want us all to switch over to using them. The environmental case is strong, and, it seems, so too is the economic case. Air-source heat pumps are ‘by far the most cost-effective, low carbon means of heating European homes’, with household energy bills likely to cost around half that of running hydrogen boilers, according to research by the International Council on Clean Transportation. It compares the cost of several low-greenhouse gas (GHG) or GHG-neutral residential heating technologies in the year 2050 including hydrogen boilers, hydrogen fuel cells with an auxiliary hydrogen boiler for cold spells, air-source heat pumps using renewable electricity, and heat pumps with an auxiliary hydrogen boiler for cold spells.
