Why heat pumps are gaining ground
Heat pumps move heat instead of generating it by combustion, which typically delivers several units of heat for each unit of electricity used. This makes them a central technology in the electrification of building heating.
In commercial buildings they can cover space heating, cooling and domestic hot water, often replacing oil or gas boilers.
Typical applications
Hotels use heat pumps for domestic hot water and pool heating, where demand is steady over the year. Offices and retail use reversible units for both heating and cooling through fan coils or air handling units.
In refurbishments, existing radiator systems may need higher water temperatures, so unit selection and emitter checks are important.
Key points in the specification
Define design temperatures, the required flow temperature, the hot water profile and the space available for outdoor units, including noise limits.
Check refrigerant type, controls integration with the building management system and the availability of local technical support.
Combining with photovoltaics
Because heat pumps run on electricity, pairing them with a rooftop photovoltaic system can reduce grid consumption during daytime operation. Sizing both together gives a clearer picture of the project economics.
