Ground Source and Air Source Heat Pump Installers in Dorset

A heat pump is a popular and energy efficient way of heating a home.

How do heat pumps work and what are the advantages of having one installed? At Energy BY DESIGN, we can help you discover the benefits of this energy source.


MCS Certified Heat Pump Installers

Energy BY DESIGN are an MCS Accredited Company, so we ensure you can take full advantage of the Governments Boiler Upgrade Scheme. As certified heat pump installers in Dorset, we can offer bespoke installations of heat pumps across Dorset and Hampshire, and will advise you on the best options for your needs rather than a ‘one size fits all’ approach.


Heat Pumps – How Do They Work?

Heat pumps work by extracting latent heat energy from either water or air and moving it across an evaporator. Inside the evaporator is a refrigerant which boils at low temperatures. A compressor compresses the hot gases until they reach high temperatures and high pressures. Once in this state they pass over a heat exchanger (known as a condenser) and it is here which we gain our usable heat energy. We now have a lower temperature refrigerant at high pressure.  It then enters a pressure relief valve and turns back into an (almost) liquid state. This cycle is then repeated.

How Does An Air Source Heat Pump Differ From a Ground Source Heat Pump?

Air source heat pumps harvest energy from the ambient air temperature and can even function down to -20ºC. They are connected to the domestic heating system by a simple flow and return pipe, and only require an electricity supply.

Ground source heat pumps work on the same principle but obtain energy from ground coils or ground water.


Advantages Of A Heat Pump

Energy Efficient, Low Cost Heating

With conventional boilers, 1kW of input energy provides less than 1kW of output energy or heat. Heat pumps can convert up to 4kW of output energy from 1kW of input energy. Therefore, heat pumps are up to 4 times as efficient as gas or oil boilers. It is the natural choice for low cost heating and hot water.

Eligible for Boiler Upgrade Scheme

With the Governments Boiler Upgrade Scheme, heat pumps should be eligible providing certain insulation criteria are met. The customer will receive a payment of £5,000 to be taken from the total quoted amount to reduce the upfront costs. To find out more, see our Incentives page.

Perfect for Heating Properties Without Gas Supply

Heat pumps are ideal for properties having no gas supply with no flue or room ventilation requirements.
