Mitsubishi air source heat pump review: the 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.

What are the advantages of Mitsubishi air source heat pumps?

Here is a list of Mitsubishi air-source heat pumps:

mitsubishi heatpump pros
  • No Gas or Oil Bills: As mentioned earlier, air-source heat pumps use electricity, and as a result, the running cost of heat pumps will add to your electricity bills. The good news is that you can get the power of your Mitsubishi heat pump from your rooftop solar panels.
  • Lower Carbon Footprint: Compared with a domestic gas boiler, a Mitsubishi heat pump can reduce your building’s carbon footprint by 40%.
  • Cooling and Heating: Heat pumps have reverse valves that allow the user to reverse the flow of the refrigerant. This makes a reverse flux of heat, which means you can both heat up or cool down your room with a single heat pump. Mitsubishi heat pumps have this ability and can provide you with both cooling and heating.
  • Quality and Durability: Mitsubishi offers the most advanced technologies in the heating industry. You can be sure about the durability and reliability of their products.
  • Efficiency: The efficiency of heat pumps reaches 300% – 400%. So you get 4 times more heat for every kilowatt of electricity the heat pump uses. 
  • Running Cost: Although natural gas and oil are usually cheaper than electricity, the running costs of heat pumps may be lower than gas/oil boilers. The reason is the higher efficiency of heat pumps compared with that of gas or oil boilers. Moreover, air-source heat pumps can be powered by rooftop solar panels, leading to a lower running cost.
  • Warranty: Mitsubishi offers 3 to 5 years of warranty for its air-source heat pumps, which is relatively good compared with other brands.
  • Inverter: Inverters are equipment that let the heat pump maintain the same heating load at any outside temperature. This means that your room temperature will be constant no matter if the outside temperature changes.
  • Low Noise: Some of Mitsubishi’s heat pumps are ultra-quiet.
  • Government Grants: The UK government offers several various grants such as Boiler Upgrade Scheme (BUS) to encourage homeowners to use electric heating systems instead of gas/oil boilers.

What are the disadvantages of Mitsubishi air source heat pumps?

mitsubishi heatpump cons
  • Working Temperature: Some of the models offered by Mitsubishi can not work when the outside temperature drops to less than -20°C. In such situations, you need a backup heating system.
  • Multiple Units: Mitsubishi’s heat pump models usually use a mini-split system. Therefore, you might need to use several units for a spacious home. This will increase the initial cost of your heating system compared to a gas boiler.
  • More Maintenance: heat pumps require more maintenance compared to gas boilers.

Mitsubishi air source heat pump customer reviews

mitsubishi heatpump reviews

Mitsubishi Electric UK has only earned 123 reviews on Trustpilot with a rating of 4 out of 5. Of course, this is not an absolute measure of satisfaction and we need more data to be able to analyse. Anyway, it’s good to read some of the most common comments from UK customers.

For example, a customer claims that they had a fault on their Ecodan and the independent installer couldn’t fix it. But when they called the Ecodan helpline, they sent someone the same day and the problem was fixed. There are many other similar comments that indicate good customer service and after-sale support. 

Overall, we can say that customers are satisfied with Mitsubishi’s air-source heat pumps, especially their customer service.

How do Mitsubishi heat pumps compare to other heat pump brands?
