The Latest Heat Pump Statistics (updated September 2023)

An Overview Of Heat Pumps

Heat pumps use ambient heat from natural sources, specifically the air, ground or water, to heat buildings and provide hot water. Electricity is only used as a supplement rather than the primary energy source. The main advantage is that heat pumps produce more heat than they consume electricity, making them highly energy-efficient.

Most of the energy heat pumps use to heat houses comes from the air, ground or water (depending on the system). Electricity supplements this heating to ensure consistent temperatures throughout a building, but the primary energy source is naturally occurring. As the technology improves and fossil fuel price fluctuations continue to disrupt markets, heat pumps are expected to become the cheapest, lowest carbon form of heating available.

Ground Source Heat Pump Statistics

A ground source heat pump generates most of its energy from heat underground. Ground source heat pumps are a long-lasting heating solution. The heat pump lasts for around 20 years, while the underground pipes can last for around 70-100 years.

  • A ground source heat pump could save a household up to £2500 on heating bills.
  • However, it could also add up to £205 to annual heating bills, depending on the system the pump is replacing. 
  • Ground source heat pumps can heat water from the ground to around 50ºC. Raising the temperature higher than this requires more electricity and will affect efficiency.
  • This type of heat pump can save between 2300kg-11,000kg of CO2 per year, depending on the type of heating system it replaces.
  • They can cost around £24,000 if the loop is buried in trenches and up to £49,000 if a borehole needs to be dug. 
  • Ground source heat pumps have a Coefficient of Performance (CoP) of 4.8. The CoP is the ratio of heating performance compared to the energy needed. A higher CoP equates to a higher efficiency device, with lower power consumption and, therefore, cheaper energy. For comparison, a gas boiler has a CoP of around 0.93.
  • Ground source heat pumps only account for 2.5% of installed pumps in the EU.
  • Ground source heat pumps can produce 70% less carbon dioxide emissions than a gas boiler – if the supplied electricity comes from renewable sources, there are no carbon emissions.
  • It’s estimated that every 100,000 homes with ground source heat pumps will reduce oil consumption by 2.15 million barrels per year.

How do ground source heat pumps work?

Ground source heat pumps work by transferring ambient heat from underground into a heating system. They utilise a network of buried water pipes (usually around 100m) in a loop. A mixture of water and anti-freeze is pumped through this loop, absorbing the heat that occurs naturally underground. 

Using electricity, the water is then compressed and its temperature raised. A heat exchanger then extracts this heat and transfers it to the building’s heating system. Any remaining heat is stored in a hot water cylinder, which can then be used for showers or run through taps.

Air Source Heat Pump Statistics

There are two types of air source heat pump; air-to-air and air-to-water. By mainly using naturally occurring heat, these heat pumps are more environmentally friendly than gas or oil boilers and can save people money on heating bills by using less electricity.

  • As of May 2023, air source heat pumps typically cost between £7000 and £13,000 to install.
  • A standard air source heat pump can save the average 3-bedroom household in the UK up to £1500 on heating bills, depending on the system the pump replaces, or add up to £135.
  • Air source heat pumps are the most popular type of heat pump, accounting for 60% of global sales in 2021.
  • Air source heat pumps typically have an efficiency rating of 300%.

How do air source heat pumps work?

Air source heat pumps take heat from the outside air. In air-to-water pumps this heat is absorbed into a liquid. This liquid then passes through an electronic compressor, further raising the temperature. The heat is then transferred to the building’s heating system and can generate hot water. In air-to-air heat pumps, heat is taken from outside and passes through fans to heat the building. They can also work as air-conditioning units for cooling buildings down during summer months.

Water Source Heat Pump Statistics

Water source heat pumps take the ambient heat from a body of water, increase the temperature using electricity, and transfer that heat into a building’s heating system. Groundwater is an effective heat source as, even on cold days, it maintains a temperature between 7ºC and 12ºC.

  • A water source heat pump has a CoP (see the ground source heat pumps section for more information) of around 6. For comparison, a gas boiler has a CoP of around 0.93.
  • Water source heat pumps could save households between £395-£2000, depending on home type and which system it replaces.
  • The water source heat pump market was worth $907.5 million in 2021 and is expected to grow at a Compound Annual Growth Rate of 5% between 2022-2030.
  • The global water source heat pump market is expected to be worth around $1.4 billion in 2030.

How do water source heat pumps work?

Water source heat pumps work by transferring heat from a body of water into a heating system. There are two types of water source heat pumps – open-loop and closed-loop systems. 

In closed-looped systems, a mixture of water and antifreeze is piped through coils or heat exchange panels installed in a water source, such as a lake, pond or river. The mixture absorbs heat energy from the surrounding water and transfers this to the heat pump.

Open-loop systems pump water directly from the source to the heat pump. Once the heat energy has been extracted, the water is pumped back to the source.

In both systems, the energy from the water is transferred to the heat pump’s heat exchanger, where a refrigerant absorbs it. The refrigerant heats up, turning from liquid to gas, which is compressed to increase the temperature and sent through a second heat exchanger. The heat gets sent to the radiators and water within the building, providing heating and hot water.
