What is a Heat Pump?

A heat pump is a device that transfers heat from one place to another, typically from a colder area to a warmer one, using a small amount of energy. 

It works on the principle of moving heat rather than generating it directly. 

In essence, it can provide both heating and cooling functions, depending on the mode it operates in.

operates in.

There are two main types of heat pumps:

  • Air-source heat pumps: These extract heat from the outdoor air and transfer it indoors during the heating season. In the cooling season, they extract heat from indoor air and transfer it outdoors. They are commonly used for residential heating and cooling.
  • Ground-source (geothermal) heat pumps: These use the relatively stable temperature of the ground or groundwater as a heat source in the heating season and as a heat sink in the cooling season. They are often more energy-efficient than air-source heat pumps but may require more upfront investment for installation.

The Boiler Upgrade Scheme

Under the scheme, eligible homeowners will be able to receive  a government grant for the purchase of a heat pump, which are more environmentally-friendly than natural gas boilers.

The Government is providing grants towards the cost of buying an air source heat pump, and eligible homeowners can get up to £7,500 (depending on eligibility) towards the cost of the heat pump and it’s installation.

We work alongside an MSC Government Accredited Umbrella Company who can help you to access the Boiler Upgrade Scheme grant.
