Long before they became the now very desirable eco-friendly alternative to boilers for heating, we started working on air to water heat pumps that were used to keep swimming pools pleasantly consistently warm.
Now, nearly 30 years later, we are highly experienced at heat pump technology, and are the “go to” local engineers for domestic heat pump owners who call us in for ongoing maintenance, servicing and repairs for their air source home heating systems.
A heat pump system captures air from outside, extracts heat energy and transfers it to the water that circulates in your radiators and underfloor heating, or feeds it into your hot water tank.
We can work on any brand of air source heat pump, but work closely with Daikin – one of the big names in UK heat pumps. Daikin recommends an annual service by qualified technicians, such as ourselves, and a maintenance contract to validate their warranty.
With good maintenance and regular servicing repairs are rarely needed, but if something goes wrong with your air source heat pump – such as a refrigerant leak, compressor issue, damage to coils or faulty sensors – we’ll have it fixed in no time.
Your Air Source Heat Pump provides you with a “green” alternative to the traditional gas boiler, saving you money on energy bills over the long term and reducing your carbon footprint. Like any appliance, however, it needs to be serviced and maintained to perform efficiently and ensure a long lifespan (up to 20 years is the norm for a well-maintained system).
There are things you can do yourself, like ensure nothing blocks the airflow around the outdoor unit (such as leaves and vegetation), and keeping filters clean. You should call us in if you notice any unusual behaviour, such as odd noises, a drop in heating output or error codes.
At least once a year our engineers should inspect the refrigerant circuit, electrical connections, inspect and clean internal components, check performance and heat output, and check the pressure settings of the heating circuit.
Many people still have doubts about whether an air source heat pump can really heat your home efficiently, especially during the coldest days of the year, when you need it the most.
These sustainable appliances work like a reverse fridge. Even when its cold outside the air still contains heat energy. The heat pump fan pulls in the outside air, passes it over a refrigerant which absorbs the heat. The warmed refrigerant is then squeezed by a compressor to increase the temperature. The hot refrigerant then passes through a heat exchanger where the heat is transferred to water, which is then circulated to your heating system and/or hot water cylinder.l
The refrigerant cools down again, expands, and is sent back to collect more heat from the outside air, repeating the cycle over and over again.
Most modern air source heat pumps are designed to work reliably down to at least –15 °C, so our west country winters are no problem for them, especially if they are safeguarded with a maintenance contract.
