ASHPs

An Air Source Heat Pump, also known as an Air to Water Heat Pump, works in precisely the same way as a GSHP, except they take the heat out of the outside air, instead of the ground. This might sound strange in the winter months, but given that the refrigerant in a heat pump boils at around -20 °C, even the coldest weather feels hot to a heat pump! Some ASHP?s in particular are designed for radiator based heating systems and can be used together with most electric boilers, oil-fired boilers or equivalent if docking is required. Some systems (usually Swedish) will work to outdoor air temperatures of minus fifteen degrees centigrade meaning that no extra heat source will be required due to the UK?s milder climate. The heat pump includes an advanced control system for optimal control. This is started by a signal from another controller, return line sensor or thermostat. Some high quality pumps can also be controlled by a specially designed controller. This connects and disconnects the additional heat source whilst also controlling switching between room heating and hot water heating.
