Air Source Heat Pumps

Air Source Heat Pumps look similar to air conditioning units and are less disruptive to install than Ground Source Heat Pumps as they do not require any digging in your garden. The main components of an ASHP are a heat exchanger, a compressor and something to transfer the heat into a water tank or heating system, such as radiators or an under floor heating system.

How it works

An ASHP works a bit like a refrigerator in reverse. The process consists of an evaporator, a compressor and a condenser. It absorbs heat from the outside air and the heat pump compressor then increases the temperature of that heat further to create useful heat.

ASHP have some impact on the environment as they need electricity to run but the heat they extract from the air or water is constantly being renewed naturally.Air Source Heat Pump

Solar Thermal Water Heating

Solar water heating systems use solar panels, called collectors, fitted to your roof. These collect heat from the sun and use it to warm water which is stored in a hot water cylinder.

Soalr Water HeatingA boiler or immersion heater can be used as a back up to heat the water further to reach the temperature set by the cylinder’s thermostat when the solar water heating system does not reach that temperature.
