Heat Pumps

GROUND SOURCE

Ground source heat pumps collect energy stored in the earth and use it to heat water in a cylinder for distribution to taps, appliances and radiators. They can also cool the house in summer. This is the most advanced technology available for home heating, hot water and cooling, because the earth itself ‘stores’ energy it is an extremely reliable and constant energy source, it creates no harmful emissions and uses a very small amount of electricity to drive the pumps themselves.

HOW DO THEY WORK

A heat pump works in the same way as a refrigerator, but in reverse. The collection system consists of a single deep borehole in the garden. Alternatively, where space permits, a looped array of pipes buried about 1.2 metres below the surface can be used. The ground source heat pump then extracts heat stored in the earth. This low temperature energy passes through a CFC-free refrigerant cycle which converts it into higher temperatures to heat the home. In summer, with an underfloor heating system connect to the heat pump the cycle is reversed, cooling the room to a comfortable temperature. If you are considering having a ground source heat pump installed you may be eligible for a grant through the Low Carbon Buildings Programme.

Ground source heat pump Vaillant Geotherm has excellent efficiency. For every 1kw of input, energy is converted into an average of 4.2kw of output energy of heat.

Therefore the heat pump has a seasonal co-efficiency of performance (COP) of 4.2.

AIR SOURCE

Air Source Heat Pump Ecodan will heat your home and supply your hot water just like a traditional boiler, but it is different from traditional boilers in a number of important ways.

First it is more energy efficient and could reduce your energy bills by at least a third. It also produces half of the Co2 of a traditional boiler, which helps to reduce your home’s impact on the environment.

Ecodan is an air source heat pump and the technology inside it is very similar to a domestic fridge. It basically  transfers heat from one place to another. The back of your fridge is warm because it is removing heat from inside the storage space to the room. A heat pump removes warmth from the air outside and transfers it inside the home, for heating and hot water.

Air Source Heat Pump Ecodan has excellent efficiency. For every 1kw of input, energy is converted in to an average of 3.6kw of output energy or heat. Therfore the heat pump has a seasonal co-efficiency of performance (COP) of 3.6.
