Heat Pumps
8.5 kW Mitsubishi Ecodan ASHP.
Heat pumps use the refrigeration cycle to transfer heat from the air, water or ground to the inside of a building to provide space heating and hot water. Heat pumps are powered by electricity, but are more efficient that conventional electrical heating systems.

Types of System

EfficiencyThe efficiency is described as the ‘coefficient of performance’ (CoP) which is the ratio of electricity input: heat output.
|
System RequirementsHeat pumps are not suitable for all properties. They work more efficiently with a low temperature heating system and are therefore suited to energy efficient, well insulated buildings and are ideally partnered with underfloor heating. However, there is scope for flexibility in the system design – heat pumps can be used with radiators and can be 'docked' with existing heating systems which can be bought in to assist the heat pump during very cold weather. In order to establish the right size of heat pump for your home, a 'heat loss' or SAP calculation is required. |
System CostsTypical 8kW system:

Running CostsCost of electricity to run the heat pump and water circulation pump. Consider running the heat pump on a special electricity tariff offered by some suppliers. Scottish Hydro E10. |
