What is R290 Refrigerant?

Air source heat pumps use refrigerants to absorb heat energy from the air outside and convert it into useable energy to heat our homes and hot water. For the last few years, R32 refrigerant has been widely used in heat pumps but, as heat pump technology continues to evolve, so too has the choice of refrigerants used in heat pumps with R290 emerging as an alternative. In this blog, we take a closer look at R290 refrigerant and its role in home heating.
