PV solar panels, wind turbines, air or ground source pumps - all of them provide great value and can deliver free energy to power up your new home.
On the top of free energy you will benefit from feed in tariffs which can generate tax free income guaranteed to be paid for another 20 years.
Solar electricity is produced when photovoltaic panels turn energy into the electricity. You can use this energy in your property, and the electricity you don't use is exported back to the grid.
SOLAR HOT WATER
Solar thermal panels absorb heat from the sun to heat up fluid inside the collector. When the fluid is hot enough it is then pumped to the hot water cylinder in your home where the heat is transferred to heat your water. On average solar thermal systems provide 40-60% of your annual hot water needs.
AIR SOURCE HEAT PUMPS
These pumps extract heat from the air, compress it, and use it to heat your house. This absorbs heat from the air into a liquid refrigerant. This fluid then passes through a compressor where the temperature is increased.
GROUND SOURCE HEAT PUMPS
These pumps extract heat from the ground and feed it into your heating system. Looped pipework is placed underground and used to extract heat from the ground by circulating a mixture of water and anti-freeze. This fluid absorbs low level heat from the ground and carries it to the heat pump where it enters a heat exchanger and compressor.
The fluid is then transferred to the heating components of the house, i.e. water filled radiators and underfloor heating. The rest is stored in a hot water cylinder which can be used for showers, baths and taps.
There are two main designs - horizontal axis wind turbines (HAWT) and vertical axis wind turbines (VAWT). Most are installed on free-standing masts but building mounted turbines are also available for small domestic scale use.
Small wind turbines suit individual households or small farms and typically range in power up to 50kW. They reach a maximum height of 35 metres. In the right location, a 20 metre tall small wind turbine can produce the vast majority of the power your building uses.
