Heat pumps are a key part of the government's promise to reach net zero in the UK by 2050, meaning no more greenhouse gas would be added to the atmosphere. Home heating currently accounts for 14% of the UK's carbon emissions.
Heat pumps work by pumping or moving heat from one place to another by using a compressor and a circulating structure of liquid or gas refrigerant, through which heat is extracted from outside sources (such as the heat of the soil in the garden or the outdoor air) and transferred to your house.
