A well-designed heat pump system transfers significantly more energy into a property as heat than is uses to extract it from the ground or air. As a result, heat pumps have the potential to lower fuel bills, particularly in properties without access to mains gas, and reduce environmental impact.

How heat pumps work

Heat pumps work by extracting solar energy stored naturally in the ground or air. They are able to utilise this energy for domestic heating and hot water.

In a well-insulated property, every kilowatt hour (kWh) of electricity used to power the heat pump can provide around three kWh of ‘free’ thermal energy. This means that a heat pump’s efficiency can reach around 400% – far more than boilers that tend to run at around 92%.

Is a heat pump suitable for your project?

Heat pumps are a good renewable alternative for a range of properties.

Efficiency and maintaining low running costs are key. With this in mind, there are a few important considerations that will help you to identify whether a heat pump is right for your project:

  1. Is the property very well insulated?
    Insulation should be up to current Building Regulation standards to ensure the heat pump both effectively and efficiently heats the property. This is why most heat pumps are installed as part of a new build project.
  2. Is there access to mains gas?
    If the answer is no, then a heat pump could be a particularly cost-effective choice. This is because for every unit of electricity the heat pump uses, it typically outputs three times the amount in heat energy. You can expect a heat pump to be more efficient and cheaper to run than an electric-only heating system or an LPG boiler.
  3. How much land is available?
    Ground source heat pumps need a good amount of land for the installation of ground loops – at least three times the total floor area of the property (ground and upper floors). Air source heat pumps require very little space, so are a good option for urban properties.

Heat pumps and underfloor heating

Underfloor heating (UFH) is the most popular heat emitter to pair with a heat pump system. This is because UFH works at much lower flow temperatures than a traditional radiator system, making it ideal for heat pumps which are at their most efficient when operating at low temperatures.
