One of the major obstacles to the widespread adoption of air source heat pumps in the UK is their elevated total cost. While Mitsubishi's heat pump prices are not the most expensive, with ground source heat pumps and some other brands being pricier, typical air source heat pump installation costs range from £8,000 to £16,000, including materials and the heating system.
However, installing an air source heat pump can lead to significant energy savings that can reduce your heating bills considerably, with potential annual savings of up to £290 (Energy Savings Trust) when replacing an old G-rated boiler with a Mitsubishi ASHP, for instance.
To support the adoption of renewable energy heating solutions, the UK government offers multiple heat pump grants nationwide, such as the Boiler Upgrade Scheme (BUS), which provides funding of up to £7,500 towards the installation of air source heat pumps.
Mitsubishi heat pump review: Pros & cons
Every system has its own pros and cons, and Mitsubishi air source heat pumps are no exception. Let’s review the advantages and disadvantages of air source heat pumps offered by Mitsubishi to see if they meet your requirements.
- Lower carbon output: A Mitsubishi air source heat pump produces 60% fewer CO2 emissions than a domestic gas boiler.
- Cooling and heating: Heat pumps have reverse valves that allow the user to reverse the flow of the refrigerant. This creates a reverse flux when transferring heat, which means you can heat up or cool down your room with a single heat pump.
- Efficiency: Heat pumps are 300%—400% efficient. So, they produce four times more heat for every kilowatt of electricity they use.
- Lower running costs: Although natural gas and oil are usually cheaper than electricity, the high efficiency of heat pumps makes them cheaper to run in the long term, allowing homeowners to save up to £290 (Energy Savings Trust) annually by replacing an old G-rated boiler with a Mitsubishi heat pump.
- Warranty: Mitsubishi offers a 3 to 7-year warranty for its ECODAN air source heat pumps, which is relatively good compared to other brands.
- Constant indoor temperatures: Mitsubishi heat pumps are equipped with inverter technology that can adjust their compressor speed to match heating or cooling on demand, providing consistent indoor temperatures despite outdoor temperature fluctuations. However, extreme temperatures may still influence the heat pump’s overall capacity.
- Low noise: Some of Mitsubishi’s heat pumps are ultra-quiet, ensuring operation at levels as low as 18dB.
- Government grants: The UK government offers various heat pump grants, such as the Boiler Upgrade Scheme (BUS), with grants of up to £7,500 to encourage homeowners to use electric heating systems instead of gas/oil boilers.
- Working temperature: Some of Mitsubishi’s models can not work when the outside temperature drops to less than -20°C. In such situations, you need a backup heating system.
- High initial cost: The upfront prices of Mitsubishi heat pumps can be substantial, often exceeding those of traditional heating systems.
- Compatibility with existing systems: Integrating a heat pump with existing heating infrastructure may require modifications, such as upgrading radiators or installing underfloor heating, to achieve optimal efficiency. These adjustments can add to the overall installation cost and complexity.
Mitsubishi heat pumps per house size
Mitsubishi’s air source heat pump sizes typically range from 4kW to 16kW, with a 5kW unit generally sufficient for an average well-insulated 3-bedroom home. It’s important to note that size refers to the heat pump’s output capacity rather than its actual physical dimensions.
Below, we’ve compiled our recommended Mitsubishi heat pumps in the UK according to your household’s size and energy needs:
| Household size | Estimated required air source heat pump size | Model series | Power output range |
|---|---|---|---|
| 1 bedroom | 3-4kW | Ecodan R32 Compact PUZ Monobloc | 5kW |
| 2-3 bedrooms | 5-8kW | Ecodan R32 Ultra Quiet PUZ Monobloc | 6kW, 8.5kW, 11kW |
| 4 bedrooms | 9-12kW | Ecodan R32 Zubadan PUZ Monobloc | 14kW |
| 5+ bedrooms | 13-16kW | Ecodan R32 Zubadan PUZ Monobloc | 14kW |
Selecting the correct size for your Mitsubishi heat pump is vital for efficiency. An oversized pump wastes resources, while an undersized one may lead to inadequate heating or cooling, resulting in higher energy consumption.
The table above provides a helpful overview of which Mitsubishi air source heat pump models are best suited to your household's characteristics, though it should be noted that this is merely an estimation. For a more accurate assessment of the various Mitsubishi models and the ideal size for your home, we strongly recommend consulting with a heat pump specialist.
