#1 Worcester Bosch Heat Pumps (Best Heat Pumps)
Worcester Bosch is perhaps more famous for its range of award-winning gas boilers, but its heat pump range is also industry-leading and ahead of the curve. If Worcester Bosch made ice cream, we’re sure it’d be great, too.
Their ground source heat pumps not only look stylish, featuring curved edges and a contemporary digital control interface, but they have also received Quiet Mark accreditation. Quiet Mark isn’t the shy kid you used to know, but an accreditation company that ensures minimal noise.
Watch Our Air Source Heat Pump UK Case Study in the video below:
One of the most common complaints concerning heat pumps is concerns about their operation noises, so it's reassuring that the brand has received approval from the organisation that acoustically tests products to enable consumers to easily identify quieter products for the home.
The Worcester Bosch range of heat pumps includes their latest CS7001iW outdoor/indoor unit, which is available in a range of different power outputs ranging from 5kW to 17kW, ideal for homes of varying sizes.
The system can operate as low as -25 meaning it can easily operate during the cold winter months, providing homes with both heating and hot water.
Worcester currently offers a 2-year guarantee on all of their heat pumps as standard, however, if you opt into Alto Energy’s MCS umbrella scheme, the guarantee is a significant 7 years long. And trust us, umbrella schemes are much better than pyramid schemes.
Worcester Bosch also offers a hybrid heat pump called the Hybrid 7000iAW.
This offers homeowners the best of both worlds and is ideal for individuals who have poorly insulated homes, or just those who have concerns about keeping their homes adequately warm in the depths of winter.
The hybrid option is suitable for smaller to medium-sized homes and depending on the outside temperature will either choose the heat pump to operate or switch to a traditional gas boiler.
Key facts on the Worcester Bosch heat pump brand:
Guarantee period: up to 7 years
Price range (fitted): £8,000 > £15,000

#2 Viessmann Heat Pumps (Second Best)
Viessmann is a relatively new entrant to the UK market, but they have dominated the European heating and cooling market for some time.
The German brand has an excellent reputation among customers and installers alike and their products benefit from German engineering and superior exterior designs.
In terms of heat pumps, Viessmann offers a comprehensive range of all types, including air-source, ground-source, air-to-water and hybrid heat pumps, so rivals have a lot of catching up to do.
There Vitocal 100-A heat pump is designed specifically for modernising properties, so the initial install time and costs may be substantial, yet you will benefit from a heat pump designed to operate at all times of the year, from the coldest of winters to whatever tries to pass for summer next year. The Vitocal is an outdoor, space-saving model, ideal for new build properties.
More heat pump guides:
It also has an energy efficiency rating of efficiency class: A+++, the highest score the rating system awards. After the Viessman, they ran out of pluses.
Just like Worcester Bosch, Viessmann also offers a hybrid air-source heat pump, which is compatible with existing heating systems, making it ideal for older housing stock. The Vitocal 200-A is their current hybrid model.
Like all Viessmann products (and your obnoxious neighbour’s car), their heat pumps benefit from superior German-engineered components, which include their heat pump gold-plated heat exchanger.
This is particularly suited to the cold and damp UK climate, as studies have shown it is resistant to corrosion.

Guarantee period: 2 years standard warranty
Price range (fitted): £9,000 > £14,000
#3 Daikin Heat Pumps (Third Best)
Daikin has been active for almost a century and during that time has built a reputation as one of the leading brands in heating and cooling technology. In fact, according to the best experts, they rank third just behind Worcester Bosch and Viessmann.
Ben Price/Heatable
In the UK, one of the brand's most popular domestic heat pumps is the Daikin Altherma with Bluevolution Technology 3 is an air-to-water system.
This heat pump is able to operate and provide warmth at temperatures as low as -25°C when you really need it. This makes it ideal for a seasonal country like the UK.
The heat pump achieves an energy efficiency rating of A++, which is impressive, but not quite as efficient as Viessmann or Worcester, hence the slightly lower ranking.
The Daikin Altherma also comes with a very user-friendly mobile app, allowing you to control the device with convenience and it gives you something else to do on your phone in the bathroom.
This heat pump is designed to be installed indoors, which may not be ideal for homeowners looking to avoid the typical heat pump noises, although it does have a relatively quiet operation. Just don’t do your meditation right next to it.
However, it was designed with easy installation in mind and benefits from hydraulic components, that are accessible from the front.

One of the brand's most popular models is its aroTHERM air source heat pump, which is notorious for its ease of installation.
Like Worcester Bosch, the brand's heat pumps are MCS accredited and Quiet Mark approved, so this is a definite advantage over competitors with more noisy models. Unless you like having conversations with your heat pump, less noise is better.
Similar to Viessmann, Vaillant has taken extra care to protect the unit from the harsh UK climate, as a result, the model has a bluefin-coated evaporator with an anti-hydro coating.

#7 Samsung Heat Pumps (Seventh Best)

The range is offered in a range of different sizes, making it ideal for small and medium sized properties.
The heat pump has all of the features you can expect in a modern appliance designed for households including a compact and lightweight design, making it simple to install. It also has the ability to be installed on the floor or wall-mounted, offering maximum flexibility.
In terms of operating temperatures, the Samsung EHS Mono range is able to operate at high water temperatures of 55°C and can still extract heat from the air in temperatures of -25°C at which point heat is a scarce commodity.
This temperature isn't as low as some of the other heat pumps we have listed, but it is certainly still quite impressive.

Guarantee period: 2 years standard warranty
Price range (fitted): £9,500 > £15,000
#8 LG Heat Pumps (Eighth Best)
Another mulinational company from South Korea, LG's THERMA V R32 air source heat pump has recieved some very positive reviews.
The THERMA V R32 was one of the first heat pumps to adopt the refrigerant gas known as R32, an environmentally sustainable refrigerant gas which has a Global Warming Potential 72% lower than that of the former most widely used refrigerant known as R410A. Guessing where this model gets its name, doesn’t even get you points when you’re in Gryffindor.
The LG heat pump also has the highest energy efficiency rating of A+++ rating, this is all due to the Revolutionary Scroll Compressor.
The THERMA model can work with a temperature range as low as -25°C and heats water to a maximum of 65°C, ideal for colder climates, but not as wide of a range as some of the other models on our list.
The digital interface is very user-friendly and enables you to change the heating and cooling schedules based on your routine.
Interestingly, it also allows you to check your energy consumption on a daily or monthly basis and control it remotely via the G SmartThinQ™ app on your smart device e.g. your mobile phone.

Hitachi is a Japanese multinational company renowned for producing high-quality and well-engineered products.
However, unlike other heating and cooling brands, they have become known as generalists rather than specialists.
The brand's most popular heat pump is the Hitachi Yutaki-S80 operating temperatures are probably the most remarkable thing about the appliance, which is also thanks to its very innovative technology. That’s a range more impressive than Freddy Mercury’s.
The appliance can produce hot water up to 80°C and even produce heat in temperatures as low as -20°C.
Hitachi's patented technology includes the Cascade R134a Heat Pump Circuit, which replaces the standard electrical element which gives a surge of energy from 45°C to 80°C, helping it to act more quickly than competitor models.
