Heat Pumps Pembrokeshire Green Energy Specialists Ground Source Heat Pumps The system works by having a collector buried and then energy is extracted from the ground and raises the temperature of the liquid circulating in the collector by several degrees. The pump increases the temperature and delivers it into your home.
The system can meet your total heating requirements and in most cases there is no need for a boiler. You can choose a heating only System heat pump or a heating and hot water Combination unit, with an output to suit your needs and size of property.
Ideally, for maximum benefit and efficiency, they are best used with under floor heating, but radiators are also a practical option.
Air Source Heat Pumps Air Source Heat Pumps use basic thermodynamic principles to convert latent/sensible heat (contained within the ambient air) into heat energy that can be used to provide heating and hot water. In this respect the device can be classified as a renewable energy source because the heat in the ambient air is replenished by the sun.
There are two types - 'air to air' and 'air to water. Air to air heat pumps release the captured energy through an air heat exchanger, which is then forced (by fan) around the dwelling by trunking, or directly into the room. Most commercial buildings use this type of heating medium. Air to water heat pumps release the energy into a water circuit which is then used in a wet heating system.
