What are the different types of heat pumps?

When it comes to eco-friendly central heating systems homeowners have several choices including solar, biomass and heat pumps. Heat pumps are one of the most popular methods of providing renewable and sustainable energy because they are easy to install and offer low running costs.

Heat pumps work by repurposing energy stored in the air or ground and distributing it around the home. But there are two main types of heat pumps available. The right choice for your home will depend on its size and location and your available budget. Here is an overview of the two types we install which should help you choose the right system.

Ground source heat pumps

Ground source heat pumps extract heat from the ground surrounding your home which is then used to heat radiators and provide hot water. The heat from the ground is absorbed into special fluid running through pipes buried in your garden. The fluid is then passed through a heat exchanger into the heat pump to provide hot water in your home.

They are typically used to heat water in domestic homes which can be used by the central heating system or to provide hot water. They are more efficient than air-source heat pumps but are more expensive to install and require land to install the ground loop.

Pros:

  • Highly efficient
  • Heats your home and water
  • Easy to maintain

Cons:

  • Can be expensive to install
  • Requires land to install the ground loop

Air source heat pumps

Air source heat pumps absorb heat from the air surrounding your home. They are essentially a refrigeration unit working in reverse. The heat from the air outside is absorbed into a fluid which is then passed through a compressor. The warm compressed air is then used to heat your home.

There are two types of air-source heat pump:

Air-to-water – Use warm air to heat water which can be passed through conventional radiators or underfloor heating pipes.

Air-to-air – Use fans to distribute warm air throughout the home. Air-to-water systems are not used much in domestic environments because they do not provide hot water. They can be installed as part of a hybrid system, however.

Pros:

  • Easier to install than ground source heat pumps
  • Works well with underfloor heating systems
  • Minimal maintenance required

Cons:

  • Not as efficient as ground source heat pumps
  • Requires space outside for the compressor
  • Can be a bit noisier

Heat pumps are tried and tested technologies that offer many benefits compared to conventional gas or electric heating systems. They release fewer C02 emissions, are cheaper to run and distribute heat more evenly throughout your home. The latest developments in heat pump technology also mean they can be installed in almost any home.
