Hitachi heat pump model range
Hitachi has a range of air source heat pumps in the UK, built for different heating and cooling needs. Here’s a quick look at their main models:
| Model | Type | Heating Capacity (kW) | Cooling Capacity (kW) | Energy Efficiency | Key Features |
|---|---|---|---|---|---|
| Yutaki S | Split, air to water | 1.85–32.00 | 3.80–20.60 | A+++ | Compact size, efficient for heating, hot water, and cooling |
| Yutaki S Combi | Split, air to water | 1.85–17.80 | 3.80–13.70 | A+++ | Integrated hot water tank, space-saving design |
| Yutaki S80 | Split, air to water | 4.30–17.80 | - | A++ | High-temperature output up to 80°C, ideal for older radiator systems |
| Yutaki M | Monobloc, air to water | 2.10–17.80 | 6.00–13.70 | A+++ | Easy installation, no refrigerant connections required |
The best Hitachi heat pump model for you depends on what you need—whether it’s heating, hot water, cooling, or all three. To keep it short:
- Go for the Yutaki S if you want solid heating, hot water, and cooling—it’s the all-rounder and works for most homes.
- The Yutaki S Combi is basically the same but with a built-in hot water tank, so it’s a space-saver.
- If your house has old-school radiators, the Yutaki S80 is probably the best pick since it can hit 80°C without needing a backup heater.
- The Yutaki M is the easiest to install because it’s a monobloc system—no messing around with refrigerant connections.
Hitachi heat pump costs
Hitachi heat pump with installation costs from £6,500 to £14,220 based on the model, system size, and installation complexity.
If you're thinking about getting a Hitachi air source heat pump, it's good to know what it'll cost—not just for the unit itself, but also for installation and upkeep. Here are estimated Hitachi heat pump costs for different models, including the cost of installing a heat pump:
| Model | Typical Price (inc. VAT) | Installation Cost | Total Cost |
|---|---|---|---|
| Yutaki S | £3,000–£6,200 | £3,500–£6,000 | £6,500–£12,200 |
| Yutaki S Combi | £4,620–£7,400 | £3,500–£6,000 | £8,120–£13,400 |
| Yutaki S80 | £7,000–£8,220 | £3,500–£6,000 | £10,500–£14,220 |
| Yutaki M | £2,600–£4,600 | £3,500–£6,000 | £6,100–£10,600 |
Getting a Hitachi heat pump isn’t just about the upfront cost—you’ve got installation and maintenance to think about, too. The table above gives you a rough idea of what you’ll pay, but the final Hitachi heat pump price depends on a few key things:
- The unit itself: Bigger systems with more power cost more. If you need high water temperatures (like with the Yutaki S80) or an all-in-one setup (like the Yutaki S Combi), expect to pay extra.
- Installation: If your home is already well-insulated and has a compatible heating system—such as underfloor heating or large radiators—you’ll keep costs down. But if your system needs upgrades, like new radiators or pipework adjustments, expect the price to climb.
- Maintenance: A yearly check-up keeps everything running efficiently, and skipping it could cost more in the long run. Expect to budget £150–£300 per year for servicing, which covers refrigerant checks, filter cleaning, and general upkeep.
Worried about the cost of an air source heat pump? There’s help available. Check if you qualify for an air source heat pump grant in the UK. The Boiler Upgrade Scheme (BUS) offers a £7,500 grant to help homeowners switch to a more energy-efficient heating system.
If you get the £7,500 grant, an air source heat pump could pay for itself in about 7–12 years based on the energy savings you’ll see each year. Without the grant, it takes longer—more like 10–15 years or even more. So, if you're thinking about making the switch, the grant definitely helps make it a quicker return on investment.
Keep in mind that the total cost of a heat pump will be affected by potential extras and installation costs, which vary by installer. That’s why it’s best to compare several installers in your area to ensure you explore all the best air source heat pumps in the UK.

Hitachi heat pump reviews
Hitachi heat pumps get mixed feedback from UK homeowners. Some users praise their efficiency (A+++ rating) and say they work well, even in colder weather.
The Yutaki S Combi is a popular choice for its space-saving design, and a few homeowners mention noticeable reductions in their energy bills after switching from gas or oil heating.
One Reddit user shared a positive long-term experience, saying: “Have Daikin, Hitachi, and Samsung—best life was with Hitachi. My current one is 8 years old and still runs like a charm. The earlier one lasted 7 years.”
But not everyone’s happy. Some units don’t last as long as expected, with reports of breakdowns after just a few years or struggling to keep up in freezing weather.
A Reddit user shared their experience with a Hitachi heat pump in a new build, stating, “Problem is it doesn’t seem to work in the cold weather! House has been getting colder all week despite the heating being 'on'.”
They reported that the unit froze up and stopped working, leaving them frustrated due to the lack of clear information or solutions online.
Installation can be tricky too, especially for models that need specific setups—not every home is a perfect fit. It’s no surprise that Hitachi holds a low 1.2 out of 5 rating on Trustpilot, reflecting these ongoing frustrations.
While a lot of people are frustrated with Hitachi heat pumps, a low rating doesn’t always mean the technology itself is bad.
In many cases, the installer makes all the difference. Heat pumps aren’t plug-and-play—they need the right setup, proper insulation, and a system that’s sized correctly for your home. If any of that is off, even the best heat pump can struggle.
That’s why picking a good installer is just as important as choosing the right heat pump. A skilled professional will make sure it’s set up properly, runs efficiently, and won’t leave you freezing in winter.
Hitachi air source heat pump pros and cons
- Serious energy savings: With an A+++ rating, these heat pumps can slash heating bills over time. Many users notice a real difference compared to gas or oil boilers.
- Not afraid of the cold (most of the time): Hitachi models are designed to handle winter conditions, with some users reporting strong performance in freezing temperatures—a key advantage over certain other brands.
- Built to last: While reviews are mixed, some users have had Hitachi heat pumps running perfectly for 10+ years, proving they can go the distance when installed properly.
- More affordable than premium brands: While not the cheapest, Hitachi heat pumps tend to be more budget-friendly than some high-end competitors.
- Perfect for tight spaces: The Yutaki S Combi’s built-in hot water cylinder means you don’t need extra room for a separate tank. Handy if space is limited.
- Plenty of options: Need something compact? Got old-school radiators? Want high-temperature output? There’s a model for that.
- Reliability isn’t guaranteed: Some units keep going strong for years, others give up too soon, according to reviews.
- Cold weather can still be an issue: While some users praise their winter performance, others struggle with units freezing over when temperatures drop too low.
- Defrost system isn’t perfect: Several users report problems with the automatic defrost function, meaning they have to manually intervene to keep the unit running.
- Customer service may be a problem: Some people get quick, helpful support. Others? A frustrating wait and warranty claim headaches.
- Limited online support: Unlike some other brands, there isn’t much troubleshooting info available online, which can make DIY fixes tricky.
- Noise levels vary: Install it in the wrong spot, and you might regret it. Some models are louder than expected.
- Control system quirks: A few users struggle with timers and settings not working correctly, which can be frustrating when trying to fine-tune heating schedules.
Hitachi heat pumps per house size
The perfect model for your home depends on your house size and heating needs. A small flat won’t need the same power as a large, older home with multiple radiators.
Below is a quick guide to help you match the right heat pump to your home size:
| House Size | Recommended Model | Why This Model |
|---|---|---|
| Small (1–2 bedrooms) | Yutaki M | Compact and easy to install. Ideal for smaller heating loads. |
| Medium (3–4 bedrooms) | Yutaki S / Yutaki S Combi | Balances efficiency and power, with an option for an integrated hot water tank. |
| Large (5+ bedrooms) | Yutaki S80 | Provides high-temperature heating (up to 80°C). Suitable for larger spaces and older homes with radiators. |
How do Hitachi air source heat pumps compare to other heat pump brands?
Let’s compare Hitachi with other leading heat pump manufacturers in the UK. Below is a breakdown of how these brands compare in key areas:
| Brand | Hitachi | Daikin | Vaillant | Panasonic | Mitsubishi | Samsung | LG |
|---|---|---|---|---|---|---|---|
| Price | £2,600–£8,220 | £3,900–£11,800 | £3,100–£8,700 | £2,870–£7,300 | £1,100–£8,600 | £1,700–£3,200 | £3,300–£6,400 |
| Types | Air to water | Air to air, air to water, ground source | Air to water, ground to water | Air to air, air to water | Air to air, air to water | Air to water | Air to air, air to water |
| Efficiency (COP) | Up to 4.9 | Up to 5.2 | Up to 5.2 | Up to 5.28 | Up to 4.9 | Up to 5.0 | Up to 5.19 |
| Average Reviews Score | 1.3 | 4.2 | 3.9 | 1.3 | 4.3 | 1.3 | 1.2 |
| Warranty | 5 years | 12 years | 7 years | 3–7 years | 12 years | 3-5 years | 5-7 years |
The cost of an air source heat pump from Hitachi falls into the mid-range price category, making them more affordable than Daikin or Vaillant but not as budget-friendly as Mitsubishi or Samsung.
However, Hitachi takes a different approach from some of its competitors, focusing solely on air to water systems—so if you’re looking for air to air or ground source options, you won’t find them here.
Efficiency-wise, it holds up well (COP up to 4.9), but Panasonic and Daikin push the numbers slightly higher, which could mean bigger energy savings in the long run.
Then there’s the warranty—5 years sounds reasonable, but when brands like Mitsubishi and Daikin back their heat pumps for up to 12 years, it raises the question: why isn’t Hitachi offering the same confidence in longevity?
To sum up, here’s why different homeowners in the UK choose specific heat pump brands:
- Hitachi air source heat pumps are chosen for their mid-range pricing, decent efficiency, and compact air to water design.
- Daikin heat pumps come equipped with advanced inverter technology, ensuring consistent temperatures and strong efficiency, even in colder conditions.
- Nibe heat pumps are built with long-term efficiency in mind, particularly in areas that experience harsh winters. With high seasonal performance ratings, they provide steady heating all year round.
- LG heat pump models focus on energy efficiency, quiet operation, and flexible installation. Their Therma V series integrates smart control features and is designed to suit various types of homes.
- Mitsubishi heat pumps, especially the Ecodan range, are built specifically for UK households, offering reliable heating, low noise levels, and straightforward installation.
- Panasonic heat pumps, like those in the Aquarea series, are well-known for their high efficiency and compatibility with existing radiator systems.
- Samsung air source heat pumps are known for their compact design and super quiet operation, making them a great choice if noise is a concern. The EHS Monobloc is one of the quietest heat pumps you can get.
- Viessmann heat air source pumps get a lot of love for their high efficiency and smart home features.
- Calorex heat pumps serve a more specific purpose, specialising in swimming pool heating and commercial applications.
- Worcester air source heat pumps, part of the Bosch family, focus on efficient home heating with seamless integration into existing systems. Known for their durability and reliability.
Is a Hitachi heat pump the right choice for my home?

However, it’s important to consider potential reliability concerns and customer service feedback before making a decision.
This is where expert advice makes all the difference. Every home is different. Every heating system has its own quirks. A professional installer can look at your setup, compare models, and recommend what will actually save you money in the long run.
Maybe it’s Hitachi. Maybe it’s another brand that better suits your needs. The only way to know? Get multiple quotes and compare your options.
