An air source heat pump is usually placed outdoors at the side or back of a property. It takes heat from the air and boosts it to a higher temperature using a heat pump. The pump then compresses the gas, which increases its temperature, and pumps it into your central heating system, where it transfers its heat to your radiators or underfloor heating (and hot water tank, if you have one). The pump needs electricity to run, but it uses less electrical energy than the heat it produces.

LG THERMA V R32 Monobloc provides reliable and powerful heating for the indoor environment. It can operate even at extremely cold weather like -25°C. Moreover, it can offer leaving water temperature of 65°C at maximum.
An air source heating system can reduce your energy bills considerably if you currently have an old or inefficient boiler.
It costs around £750 per year to run a pump for a 3-bedroom semi-detached house, and £975 per year for a 4-bedroom detached house. The Energy Saving Trust estimates these annual savings from an air source heat pump for a 4-bedroom detached house in England, Scotland and Wales:
The EST also estimates annual Renewable Heat Incentive (RHI) payments between £875 to £1,030 a year.
Here we see another installation of an ASHP (Air source heat pump) buffer vessel, and H/W high efficiency cylinder. These works are being undertaken to a high-end refurbishment project on behalf of the builder and clients. UFH (16mm barrier pipe supplied by The solar and heat store.com) on the ground floor, and stainless steel spreader plates on the 1st floor. 2 x manifolds, and a WiFi smart control room thermostat system. We also have 4.5kw of Solar PV on the roof, providing some 4380 kWh of useable electricity, almost completely offsetting the average daytime requirement of the heating system.
