Yes, many air source heat pump systems can provide space heating and domestic hot water where the system is designed for both. They may connect to radiators, underfloor heating and a suitable hot water cylinder, depending on the property and system design. Suitability depends on heat loss, insulation levels, heating emitters, hot water demand, controls and installation requirements.

Air source heat pumps may be a lower-carbon heating option compared with fossil-fuel heating systems, particularly where the electricity source is lower carbon and the system is correctly designed and used. Emissions impact depends on the existing system, electricity source, property condition, installation quality and usage.

Running costs may be lower or higher depending on the heating system being replaced, heat pump design, property insulation, flow temperature, electricity tariff, controls, occupancy and usage. A well-designed heat pump can be efficient, but savings are not guaranteed.

Air source heat pumps can sometimes be combined with solar PV where the property, electrical setup, heating demand and system design are suitable. Solar PV may help offset some electricity use, but savings depend on system size, generation, export arrangements, battery storage, heating demand, energy tariffs and usage.
