Heat Pumps UK

Heat pumps: a solution to the energy and climate crisis
At a time when gas and heating oil prices are skyrocketing, more and more people are looking for alternatives. The heat pump quickly becomes the ideal option.

What are the benefits of using heat pumps

Efficiency, Save Your Energy Bills
Provide Warm and Cold Air
Supply Hot Water
Dry Clothes
Reduces Harmful Emissions
Minimal Maintenance

What type of heat pump should you choose in UK?

The type of heat pump choice depends above all on your situation. If you live in a region with a colder climate, an air-to-air or air-to-water heat pump will not be able to produce heat all year round. In these geographical areas, it will probably be more interesting to consider installing a geothermal heat pump or to couple an air-air or air-water heat pump with another heat source.

The air-to-air heat pump will draw energy from the outside or inside air, heat it and inject it directly into the room to be heated. It is undoubtedly the most accessible equipment. However, the air-air heat pump does not heat the water in the sanitary facilities. Its performance will be less or zero when the temperatures are at their lowest.

By recovering the energy present in the air, an air-water heat pump heats the water in the heating circuit as well as the domestic water. Easy to install and quite accessible, this heat pump is recommended in regions where the temperatures are milder.

A geothermal heat pump draws heat from the ground to heat the water in the heating circuit and sanitary facilities. This installation is a little more complex to implement. It requires the ability to deploy a large network of heat sensors underground, horizontally, or vertically. More difficult to install and more expensive, this installation nevertheless has the advantage of offering better performance throughout the year. From a certain depth, the temperature in the ground varies very little, whatever the season.

Less widespread, the water-water heat pump works on the same principle as a geothermal heat pump. The difference lies in the fact that it will draw heat from underground water, at the groundwater level. It is also a very powerful solution.

Costs of Heat Pumps Factor

The price range for heat pumps is therefore wide! This is explained in particular by the very many criteria likely to influence the budget to be provided. 

  • The type of technology: geothermal devices require land development work and therefore have a higher cost;
  • The heat release method: the use of a refrigerant (air/water or water/water) is a more expensive process than simple heat ventilation (air/air), but also offers better performance;
  • The coefficient of performance (COP) of the heat pump: defines the relationship between the electrical consumption of the appliance and the quantity of heat supplied. A high COP is the sign of a more efficient and generally more expensive heat pump to purchase;
  • The size of the dwelling and the total area to be heated. For example, the purchase price of an air/water heat pump reaches on average £65 to £90 per square meter heated;
  • The outside temperature and the climatic zone. In the coldest regions, you will have to move towards powerful and therefore more energy-consuming models.
  • Any options offered by the device, for example, the production of domestic hot water with an integrated tank, or the heating of the swimming pool water.

Average Heat Pump Costs by Type In UK

TypeInstallation Cost
Air-to-air heat pump£9,000 – £17,000
Air-water heat pump£9,000 – £19,000
Water source heat pump£10,000 – £20,000

Cost To Running A Heat Pump

The electricity consumption of a heat pump varies according to the power of the device, the characteristics of the accommodation to be heated, or the temperature outside the accommodation. Here are some indicative examples :

  • An air/air heat pump with a COP of 4 will consume around 5,100 kWh per year in a 100 m² house, i.e. a bill of around £1418;
  • A geothermal heat pump with a COP of 5, installed in a 150 m² house, will consume 5,250 kWh per year, ie an electricity bill of £1459.;

Cost To Repair A Heat Pump

RepairAverage Cost
Electrical work£100–£600
Clear blockage£80–£150
Defroster repairs£100–£650
Compressor and condenser£1,500–£4,500

Heat Pump Grants In UK 2022

From April 2022, homeowners in England and Wales who install low-carbon heat pumps in their houses could be eligible for a one-time £5,000 subsidy from the government to help them replace inefficient gas boilers. A £3.9 billion scheme to make all heating systems low carbon by 2035 includes the program.

do I need a home heat pump?

Will a heat pump reduce my energy costs?

Energy savings

If you’ve ever heard of heat pumps, you know they run on renewable energy .
They capture calories from the earth, water or air to heat your home.
This operation therefore makes it possible to heat your home using inexhaustible and free energy .
By installing this type of equipment, you will say goodbye to fossil fuels (oil, gas, etc.)

Money savings

Well, this point follows directly from the first.
By consuming less energy, the heat pump allows you to reduce your heating bill.
Yes, a heat pump consumes 2 to 4 times less energy than a traditional heating mode (electric heating, gas boiler, etc.).
It therefore allows you to save 75% on your energy bill.
