Eco energies based in Letchworth Garden City Covering Hitchin, Baldock, Stevenage, St Ippolyts and North London There have been major improvements in green eco energy technologies in recent years making them viable for domestic and commercial use. The current leading eco technologies relevant to use in the UK domestic market are solar thermal, solar panels, ground source heat pumps and air source heat pumps.These renewable or green technologies are designed to generate energy (in the form of electricity and heating primarily), without using up fossil fuel (oil and gas) or releasing the greenhouse gas CO2 into the atmosphere therefore making them clean energy technologies. We are strong supporters of renewable energy solutions and our heating engineers are certified installers of these renewable energy solutions. These eco technologies are tried and tested both in the UK. Please note that finance options are available for new renewables. Please get in touch to find out more!Solar thermalSolar collectors on your roof or wall use the sun’s radiation to heat water and then the water is stored in a highly insulated storage tank which allows for domestic or commercial usage. Solar water heating is one of the oldest types of renewable energy technologies. Solar water heating systems can achieve savings on your energy bills. Solar panelsPhotovoltaic cells convert the sunlight into electricity, which can be used to run household appliances and lighting or sell back to the grid. These PV cells don’t need direct sunlight to work, they can still generate some electricity on a cloudy day. Ground source heat pumpsPipes are buried in the garden to extract heat from the ground. The temperature underground stays relatively constant around the year and Ground Source Heat Pumps take advantage of this stable source of energy. This heat can then be used to heat radiators, underfloor or warm air heating systems and hot water in your home. Due to their low temperature output and efficiency range, ground force heat pumps are better matched to underfloor heating than to radiators in the home. Air source heat pumpsAir source heat pumps absorb heat from the outside air. An ASHP extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as -15° C. An Air Source Heat Pump is easier to install than a Ground Source Heat Pump.
