Air Source Heat Pumps
Air source heat pumps have become one of the most popular renewable heating options for Hertfordshire homes, offering a practical route to lower-carbon heating without the extensive groundworks associated with ground source systems.
By extracting heat from the outside air and transferring it into your home, an air source heat pump can operate efficiently even in cold weather conditions, making it a genuinely viable alternative to a conventional gas or oil boiler. At Pettifer Plumbing and Heating, our engineers are qualified to design and fit air source heat pump systems for residential properties, helping homeowners make the transition to renewable heating with confidence.
Understanding How Air Source Heat Pumps Work
An air source heat pump consists of an outdoor unit that draws in air and passes it over an evaporator coil containing refrigerant. The refrigerant absorbs the heat from the air and evaporates, and the resulting gas is then compressed, which raises its temperature further. This heat is transferred into your home’s heating circuit via a heat exchanger, warming water that circulates through your radiators or underfloor heating system and supplying your hot water cylinder.
The system can extract useful heat from the air even when outdoor temperatures drop below zero, making it effective throughout the UK’s winter months. Modern air source heat pumps are quiet in operation and compact in footprint, with the outdoor unit typically no larger than an air conditioning unit.
Getting The Most From Your Heat Pump Installation
The performance of an air source heat pump depends significantly on how well the system is designed and how compatible it is with your property. Homes with good levels of insulation benefit the most, as lower heat loss means the system does not have to work as hard to maintain a comfortable temperature. Underfloor heating is the ideal distribution method because it operates at lower flow temperatures, which is where heat pumps are most efficient.
However, with correctly sized radiators, heat pumps can also perform well in conventional radiator-based systems. Our engineers will carry out a full heat loss assessment of your property before specifying the system, ensuring the heat pump is correctly sized and that the installation will deliver the performance you expect.
Long-Term Benefits and Ongoing Maintenance
Once fitted, an air source heat pump requires minimal maintenance compared to a gas boiler, with no annual Gas Safe service requirement for the heat pump itself. That said, we strongly recommend scheduling a routine maintenance check each year to keep the system running at optimum efficiency, identify any developing issues early and maintain the manufacturer’s warranty. The outdoor unit should be kept clear of debris, and the refrigerant levels and electrical connections should be inspected periodically by a qualified engineer.
