Space and domestic hot water heating with air to water heat pumps Air to water heat pumps work on the “refrigerator principle”. Whereas a refrigerator draws heat out from its interior and pushes it outside, a heat pump draws heat from outside and pushes it inside the house as heat energy. The ambient air is used as a primary regenerative energy source for space heating and domestic hot water.
A heat pump extracts heat energy from the atmosphere. It requires only 1 kW of electricity to generate 3 to 5 kW of thermal energy.
Low Running Costs
Low running costs can help to reduce household energy bills.
No Need for Fuel Storage
A Heat pump removes the need for fuel to be delivered and stored at home; a common problem for homes that are in off-gas areas and rely on alternative fuels, such as oil.
Heat pumps operate using electricity (including from alternative sources such as solar power) and produce no emissions, making them much more environmentally-friendly than traditional heating systems.
Efficient Regardless of Temperature
Heat pumps can operate at high efficiency levels even in cold temperatures. Just 25% of the energy used by a heat pump is provided by electricity, with the remaining 75% being generated by the environment through the ground, water or air (depending on your type of heat pump system).
The utilization of natural energy sources such as air, ground, and water mean the approach to heating and hot water production is particularly sustainable.
Heat pumps are incredibly quiet and can therefore be positioned anywhere without causing any noise disruption.
Heat pumps work well with both underfloor heating and radiators with low surface temperatures.
Heat pumps can be used as part of a climate-controlled system within the home and integrates easily with a range of controls, including smart home accessories.
Long Service Life
Modern heat pump units have life expectancies which are on average double that of a typical domestic boiler, with boilers typically expected to last around 10-12 years, and heat pumps having an average lifespan of 20-25 years.
Heat pumps have a robust design and very few moving parts meaning that they require very little maintenance (yearly checks are advised but not required), especially in comparison to the annual maintenance required of a traditional boiler.
