Eco Technologies

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:

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.

Solar Thermal (Solar Water Heating)

solar trade association uk mapSolar 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.

 Based on the results of recent field trial, typical savings from a well-installed and properly used system are £55 per year when replacing gas heating and £80 per year when replacing electric immersion heating.  Source Energy Savings Trust.

Solar Panels (PV) (Solar Photovoltaic Cells)

Solar PV Panels - Solar Photovoltaic CellsPhotovoltaic 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.

A 3 kWp system can generate over 2,500 kilowatt hours of electricity a year – that’s around three quarters of a typical household’s electricity needs. Source Energy Savings Trust.

Ground Source Heat Pumps (GSHP)

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.

A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe – called a ground loop – which is buried in your garden. Heat from the ground is absorbed into the fluid and then passes through a heat exchanger into the heat pump. As the underground  temperature stays fairly constant throughout the year a GSHP can be used effectively all year round.

The length of the ground loop depends on the size of your home and the amount of heat you need. If garden space is limited, a vertical borehole can be drilled instead.

A quality system can save £130 compared to a gas heating system and rather more compared to electric, oil or solid fuel. Source Energy Savings Trust.

Air Source Heat Pumps (ASHP)

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.

Air source heat pumps can perform better with underfloor heating systems or warm air heating than with radiator-based systems because of the lower water temperatures required but can be used to heat radiators and hot water in your home.

Exhaust Air Heat Pumps

Exhaust air heat pump uses otherwise wasted heat in the warm air areas of your home (bathrooms, kitchen) and transfers that heat to hot water.

They use the same heat transfer principles as air source and ground source heat pumps. The combination of the exhaust air heat pump and underfloor heating gives a system that provides a high degree of comfort but will also be economical to run.
