Eco coil heating’s Ground and Air pumps work by passing water through the ground inside a coil which is heated by transfer of the natural heat and insulation properties of the ground. This natural heat retention is commonly known as solar gain or solar retention.
This heated water comes into the heat pump were the minimum of energy (normally electrical) is applied to boost the temperature to the required level for internal heating and hot water systems. The heat from this water is transferred to the isolated domestic supply and sealed heating system water within the heat pump. The water that was heated from the solar retention properties of the ground is pushed through the coil again to be heated and so the cycle continues. The water heated by the ground in the coil and the domestic and heating waters never mix.
These systems have a slightly higher capital cost. However they are exceptionally efficient, and recognised as an ecologically sound and desirable system. They can be used in either domestic or commercial situations. And are subject to significant UK and Scottish Government grant subsidy.
There are 3 Types of Heat Pumps (Click below for more information):
• Air Source Heat Pump
• Ground Source Heat Pump
• Bore Holes
