What is an air source heat pump?

Air source heat pumps (ASHPs) work in a similar way to a fridge, only in reverse. Powered by electricity, they extract naturally occurring heat from the air - even when temperatures are below 0° - and amplify it. The resulting heat is then used to heat your home.

Air-to-water and air-to-air are the two main types of ASHPs. Air-to-water heat pumps are more commonly used in UK homes. They transfer heat to water, which is distributed via a central heating system. Air-to-air heat pumps use a warm air circulation system.

2 years’ annual servicing included

When you choose ScottishPower to install your air source heat pump (ASHP), you’ll benefit from a 2-year installer warranty [5], which covers workmanship related issues – for example, issues relating to the design and/or the newly installed system. We’ll also include 2 years’ annual servicing from Domestic & General [5] as part of the installation. This helps to keep your ASHP working safely and efficiently, while validating the manufacturer’s warranty.

  • First two annual services included
  • Extended 7-year manufacturer warranty [6]

Are you eligible for a free air source heat pump?

As part of the Government’s ECO scheme, we’re working with eligible customers to help improve the energy efficiency of their homes and help lower bills too. If your home has a poor EPC energy efficiency rating (of D, E, F, G), and you receive certain benefits, we could help you install insulation and upgrade your current heating system for free.

How efficient is an air source heat pump?

Air source heat pumps (ASHPs) are one of the most efficient and sustainable heating solutions for homes. They extract ambient heat from the environment and can provide more heat than they use in electricity. While gas combi boilers typically have a 90% maximum efficiency, ASHPs can achieve an efficiency of 300% across the seasons [2].

Heating homes and buildings using gas, oil or liquified petroleum gas (LPG) is one of the biggest contributors to the UK’s carbon emissions [3]. Installing an ASHP could save more than 2 tonnes of carbon per year [4]. You can lower your emissions further with one of our 100% green electricity tariffs.

A gas boiler will produce less than 1kW of heat energy for every kW of gas consumed. A heat pump on the other hand harvests renewable energy from the outdoor air so will produce 3 or more kW of heat energy for every kW of electricity consumed. https://les.mitsubishielectric.co.uk/homeowners/our-heat-pumps.

Comparing a property heated with a modern gas boiler (17,000kWh x 92% Gas Boiler Efficiency x 0.208kgCO2e/kWh = 3.8 Tonnes CO2) vs. an air source heat pump (17,000kWh x 270% ASHP Efficiency x 0.277kgCO2e/kWh = 1.7 Tonnes CO2).

Please note, it is a requirement of the manufacturer’s warranty that an annual service be carried out to keep your heat pump working safely and efficiently. If a service is not conducted annually, the manufacturer’s warranty may become void.
