Heat Pumps

There are two different type of Heat Pump: Air Source and Ground Source. The heat pump works in the same way as the fridge you have in your home. It uses refrigerant to transport heat energy from the food inside the cabinet and that heat energy is transferred to the kitchen via the condenser (the warm tubes on the back). With an Air Source Heat Pump it takes heat from the air and the heat given off by the condenser is enough to supply hot water for heating and showers or baths. Similarly, a Ground Source Heat Pump takes its heat from the earth.

Like the fridge at home, heat pumps are very reliable and cost little to run especially when compared to oil, LPG or electric. Air source heat pumps use air as the source of ambient heat energy. They do not rely on a collection system and simply extract the heat from the source at the point of use. Air source heat pumps can be fitted outside a house or in the roof space and generally perform better at slightly warmer air temperatures.

What are the key benefits of heat pumps?

Heat pumps are already well established across Europe and are becoming more popular in the UK. As well as low running costs and reduced carbon dioxide emissions, heat pumps have other benefits:

Heat pumps can be incorporated into many UK homes. They are more suited to newer highly insulated properties and are not always suitable for flats. Once installed and connected to the heating and hot water circuits they are fully automatic. Heat pumps are also easily integrated with solar hot water systems to provide a comprehensive heating and hot water system.

Water source heat pumps need a source of water such as a lake, river or stream and air source heat pumps simply need the outside air.

Fit & Forget
Very little maintenance is required if a well designed heat pump system is installed properly. Equipment should operate automatically with very little noise.

Heat pump components have long life expectancies and high reliability. Life expectancy for the pump is around 20 years.

Heat pumps give out more energy (heat) than they use (electricity), sometimes much more. If a heat pump has a 'coefficient of performance' (CoP) of four that means at a given point in time it is generating 4 units of its own heat for every unit of electrical energy used. However, the average system efficiency of the whole system over the year, including any top-up electricity for water heating will be less than the quoted CoP.

Heat pumps can be used to provide all the heating and hot water needs for your home, or they can be installed to provide only some of your home's heating and hot water to work alongside an additional heat source for example a boiler, electric immersion heater or wood stove for the coldest days.
