Hitachi Heat Pump Product Ranges
Best Efficiency: Yutaki M
Offering a cost effective heating solution for your home that will still provide a reliable performance level, the Yutaki M series is our best pick for the most efficient heat pump available from Hitachi. Carrying a Microgeneration Certification Scheme (MCS) certificate for quality assurance, the Yutaki M provides you with a highly customisable system that will keep running costs low.
Sadly, the Yutaki M series can only be installed outside your home, while the other two models mentioned in this article can be installed both inside and outside. This could be a major drawback if you do not have the required amount of installation space outside your home.
- Efficiency Rating: A++ to A+++.
- Minimum Heating Temperature: -20°C to -25°C.

Best In Operating Conditions: Yutaki S80
If you are looking to save space by installing a smaller heat pump, then look no further than the Yutaki S80. Not only is this model the smallest out of the three mentioned in this article, but it also offers the highest hot water temperature at 80°C.
The smaller operating conditions required by the Yutaki S80 make it a popular option in the air source heat pump market as it is more accessible than larger models. However, it is also one of the highest quality products available by Hitachi and comes with a premium price tag.
Additionally, you should also take into consideration that this heat pump will take longer to install due to the complex nature of its design.

Best For The Environment: Yutaki S Combi
One of the key benefits of the Yutaki S Combi is that the system features an integrated hot water cylinder, which can help you save a significant amount of space when installing the system in your home. Additionally, this Hitachi model is the only system manufactured by the Japanese company that offers a back-up heating element. This ensures that your house will still receive hot water, even during an emergency.
However, these additional benefits come at a cost. While the S Combi more than makes up for the price increase with its special features, there are cheaper models available on the heat pump market.
- Efficiency Rating: A++ to A+++.
- Minimum Heating Temperature: -20°C to -25°C (depending on the model).

Why Should I Install A Hitachi Heat Pump?
Renewable energy sources are becoming increasingly more popular and necessary as people look to reduce their cost and be more environmentally-friendly. Heat pumps are very much taking the place of combi boiler and traditional central heating systems and offer many advantages but also a few drawbacks.
| Advantages Of Heat Pumps | Disadvantages Of Heat Pumps |
| More Environmentally Friendly: Air source heat pumps work by extracting the heat from outside your home and bringing it inside. This makes this renewable energy source vastly more environmentally friendly compared to the traditional boiler systems (such as heat pumps vs gas boilers) that rely upon the burning of fossil fuels. | Can Be Expensive: In order to run a heat pump on your property, the system will require electricity which is known for being more expensive compared to traditional gas boilers. However, the significantly higher efficiency level that comes with heat pumps (which typically stands at 300% or more) means that you will only see a marginal increase when it comes to air source heat pump running costs – and it may even be less if you’re switching from an old, poorly rated gas central heating system to a much more efficient heat pump. |
| Provide Heating And Cooling: Not only will your air source heat pump work by maintaining a high temperature inside your home during the winter months, but it can also extract cold air during the summer. No matter the time of the year, a heat pump will make your house an even more comfortable place to live. | May Not Be Suitable For Your Property: Heat pumps require a lot of space, often both indoors and outdoors. Not only might you need outdoor space to install your heat pump, but indoor room for a hot water cylinder. Additionally, you must also ensure that your property has sufficient insulation to help maintain the heat that heat pumps generate for your home. Planning permission may also be an issue for some properties. |
| Low Maintenance: Another key benefit of air source heat pumps is that they are extremely low maintenance. All you need to do in order to keep your heat pump working effectively is to ensure it remains clean and that nothing obstructs or damages the system. | You May Need To Purchase New Radiators And Underfloor Heating: If your property does not feature large radiators or underfloor heating, you may not receive the required heating benefits in order to keep your home at a comfortable temperature during the winter. |
Hitachi Heat Pumps FAQs
Q: Is My House Suitable For A Hitachi Air Source Heat Pump?
A: In the UK, most residential property types will be suitable for the installation of an Hitachi air source heat pump. However, you must ensure that you have:
- An adequate amount of radiators that are well sized.
- A home that meets the required insulation levels needed to ensure that a heat pump will be able to heat your home effectively.
- Enough space both inside and outside your home for the required equipment to run your heat pump.
If you are unsure as to whether your home fulfils the requirements for an Hitachi air source heat pump, why not get in contact with us. At Heat Pumps UK, we can help you find the perfect installers for your project.
Q: Are Hitachi Heat Pumps Loud?
A: There is a common misconception that air source heat pumps are quite loud when they are running, but just how noisy are air source heat pumps? Well, whilst you may occasionally notice a background hum while your heat pump is working to heat your home and water, typically Hitachi heat pumps are considered quiet. Some indoor units operate as low as 19 decibels of noise. while outdoor units typically have noise levels between 39 dB and 67 dB.
Q: Can I Get A Free Air Source Heat Pump?
A: Through the Boiler Upgrade Scheme (BUS), you are able to apply for up to £7,500 to help pay for the cost and installation of either an air source heat pump or a ground source heat pump. However, to be eligible for the scheme:
- You must live in either England or Wales.
- Your home must have a valid Energy Performance Certificate (EPC) rating, while also having up to date insulation.
However, if you live in Scotland, then the Home Energy Scotland scheme may be able to help you.
