Renewable Energy - Heat Pumps

Where Heat Pumps are used for heating, they are capable of highly cost-efficient energy applications because they tap into a limitless supply of clean, pollution-free heat – either the surrounding air or heat captured in the ground – all you pay for is the energy to transport that heat, and in some applications, most of this energy can be reclaimed, too.

In the same way that a fridge uses refrigerant to extract heat from the inside, keeping your food cool, heat pumps extracts heat from the outside air or ground, and uses it to heat your home and hot water.

Air source heat pumps

Air Source Heat Pumps are covered under the Microgeneration Certification Scheme as an MCS approved technology. This means DHR as an MCS Accredited installer are able to install MCS Accredited Air Source Heat Pumps and offer consumers The Renewable Heat Incentive.

Air source heat pumps (ASHP) absorb heat from the outside air. This is usually used to heat radiators, underfloor heating systems and hot water in your home. It is even possible for air source heat pumps to extract useful heat from air at temperatures as low as minus 20°C.

For every unit of electricity used to power the pump, 3-4 units of heat are produced, making it an efficient way of heating a building.

An air source heat pump should cover the heating requirements of a well insulated property. Due to the lower temperature compared with traditional boilers, it is essential that your home is insulated and draught proofed. These measures will lower your heat demand and make the system more effective.

Ground Source Heat Pumps

Ground source heat pumps use pipes buried in the garden to extract heat from the ground. This is usually used to heat radiators or underfloor heating systems and hot water.

Beneath the surface, the ground stays at a fairly constant temperature, so a ground source heat pump can be used throughout the year – even in the middle of winter.
