Mitsubishi Electric Ecodan air source heat pump FAQ
How much is a Mitsubishi Electric Ecodan air source heat pump installed in the UK (2026)?
A Mitsubishi Electric Ecodan air source heat pump costs £9,000 - £14,000 fully installed in the UK before any support (indicative, June 2026, with 0% VAT already applied). After the £7,500 Boiler Upgrade Scheme grant in England and Wales, that is illustratively £1,500 - £6,500 out of pocket. The smallest model (Ecodan R290 8.5kW) starts around £9,000 pre-grant; the largest (Ecodan R290 10kW) tops out around £14,000. Combi-to-cylinder conversions and radiator upgrades add to these figures, so always confirm with a written quote.
Is a Mitsubishi Electric Ecodan heat pump eligible for the £7,500 grant?
Yes. Every air-to-water unit on this page qualifies for the Boiler Upgrade Scheme in England and Wales when it is fitted by an MCS-certified installer, who applies for the grant on your behalf so it comes straight off the quote. Off-gas homes replacing oil or LPG heating can claim £9,000 instead, until 31 March 2027. Scotland uses the Home Energy Scotland grant and loan instead; Northern Ireland currently has no equivalent scheme. Grant details accurate as at October 2026.
Is Mitsubishi Electric Ecodan a good air source heat pump brand?
Mitsubishi Electric builds its Ecodan heat pumps in Livingston, Scotland. The current R290 range runs from 5 to 12 kW, reaches flow temperatures up to 75°C for homes keeping their radiators, and the 8.5, 10 and 12 kW sizes all come in single phase. Mitsubishi Electric Ecodan is best suited to homes keeping their existing radiators, from a uk-built range.
What is the warranty on a Mitsubishi Electric Ecodan heat pump?
3 years as standard; 5 years through an Accredited Ecodan Installer and 7 through a Heating Business Solutions Partner. Register within 30 days of commissioning or cover drops to 12 months. Cylinders get 3 years at every tier. Workmanship cover for the installation itself comes separately from your installer. Most extended terms depend on registering the product and annual servicing, so keep your installation paperwork and MCS certificate.
How efficient is a Mitsubishi Electric Ecodan air source heat pump?
The Ecodan R290 8.5kW has an MCS-certified SCOP (seasonal coefficient of performance) of 4.47 at 35°C flow and 3.51 at 55°C, so over a heating season each 1 kWh of electricity delivers about 3.51 to 4.47 kWh of heat, depending on how hot your system runs. At a 45°C design flow and the Ofgem cap rate (26.32p/kWh), 10,000 kWh of heat costs an estimated £660 a year, against roughly £890 for a 90%-efficient gas boiler at the current cap gas rate (7.97p/kWh from 1 October 2026). Estimates, not quotes; heat pump time-of-use tariffs can do better.
How long does a Mitsubishi Electric Ecodan heat pump last?
With an annual service, heat pumps are generally expected to run well beyond their warranty period (Mitsubishi Electric Ecodan: 3 years, up to 7 with conditions). Longevity depends on correct sizing (the MCS heat-loss survey), sensible siting and regular servicing. Confirm design life and extended-warranty options for your specific model with your MCS-certified installer.
