Air source heat pumps are a highly efficient way of heating your home, providing a renewable energy alternative for homeowners. Air-to-water heat pumps can even generate enough energy for you to earn money from them through the government’s Renewable Heat Incentive (RHI) scheme. Over time, through reduced energy bills and the RHI scheme, you could be making back the upfront cost of the appliance.
With there being a growing number of companies manufacturing air source heat pumps, it can be hard to know which one you should invest in. That’s why we’ve compared some of the most popular models on the market to find out which is the best and make sure that you install the perfect air source heat pump for your home.
What are Air Source Heat Pumps?
Air source heat pumps extract heat from the air outside and use it to warm your home and some models can even do so in temperatures as low as -25°C. You can either install one to run alongside your existing heating system or to replace an old one.
To put the efficiency of an air source heat pump into context, most gas boilers have an efficiency rating of about 90%, meaning that 10% is wasted. The average air source heat pump on the other hand has an efficiency of 300%, producing 3 times more energy than it uses.
Once installed, your air source heat pump could operate for over 20 years but will require maintenance during that time.
Air Source Heat Pump Manufacturers
Now we know what air source heat pump does, it’s time to take a look at the different models available. In the table below, we’ve put the key information about some of the most popular models side-by-side to help you see what each one has to offer.

ErP Energy Efficiency Rating
Daikin has over 90 years worth of experience manufacturing air conditioning and climate control solutions, building a worldwide reputation for quality and technology.
The Daikin Altherma ERSQ AV1 is an air-to-water heat pump that may help lower the energy bills and CO2 emissions of your home. With an operation range that goes right down to -20°C, you’ll know that you can rely on this unit even in the coldest weather.
This air source heat pump comes fitted with inverter compressors that continuously adjust the compressor speed to the demand of the home, so there are fewer power-consuming stops and starts. Thanks to this, energy consumption can be decreased by as much as 30% while keeping your home at a consistent temperature.
A Daikin ERSQ AV1 is likely to be priced at around £2,000, without the added cost of installation.
What do the customer reviews say?
Daikin reviews frequently say that their main motivation for installing the Altherma ERSQ AV1 was to make their home more environmentally friendly and customers are happy with the results, seeing significant decreases in their energy bills.
Mitsubishi Electric has amassed almost 100 years of experience in providing reliable and high quality products since being founded in 1921. Now, Mitsubishi air source heat pumps are some of the most advanced on the market.
With an ErP rating of A++, you know that the Mitsubishi Ecodan Monobloc will be a highly efficient addition to your home. As a self contained unit, it only requires water and electric connections so there’s no need for gas supply, flues or ventilation. It will continue to work in the most extreme conditions, still being able to function in temperatures as low as -25°C. Thanks to the low maintenance required and quiet operation, it might be easy to forget that you have an air source heat pump working away.
A Mitsubishi heat pump from the Ecodan range could cost between £2,000 to £5,000, but this doesn’t include the cost of installation which will vary.
What do the customer reviews say?
Reviews of the Ecodan Monobloc see customers praising the appliance for its quiet operation and shortly after installation they begin to see reduced heating bills, increased efficiency and lower carbon emissions.
A Swedish company, Nibe has grown to become the leading manufacturer of domestic heating products across the Nordic countries, Poland and the Czech Republic with offices all around the world.
Their Nibe F2040 air source heat pump is a highly efficient unit that boasts an A+++ efficiency rating. All of their units have been designed to make installation as smooth as possible, with their outdoor units always coming fitted with an anti-vibration water connection.
To help you keep an eye on the status of your heat pump anytime, the NIBE Uplink app can provide you with a quick overview and current status of the heat pump and the heating. In the unlikely event that there’s an issue with your unit, then you’ll receive an alert directly to your device.
This Nibe heat pump could cost around £7,000 without installation, the price of which will vary from installer to installer.
What do customer reviews say?
The Nibe F2040 receives positive reviews largely because the installation causes very little disruption and it can be retro-fitted into existing properties. Customers see the benefits of installing a NIBE system almost straight away as it helps to lower energy bills.
Samsung EHS Monoblock
Samsung are widely recognised for their phones but they’ve also been doing years of research into what makes a great air source heat pump. This research has resulted in them manufacturing the EHS Monoblock range.
The Samsung EHS Monoblock is easy to install and thanks to being a compact, lightweight unit it can be wall mounted, rather than floor standing. The unit supplies water up to 55°C and can operate in temperatures as low as -25°C all with quiet operation.
A Samsung heat pump may potentially cost between £1,750 and £4,000 without the installation which will add to this total.
Which is the Best Air Source Heat Pump?
All of these air source heat pumps are highly efficient, which makes them particularly hard to split and select a winner. If you’re looking for an alternative to a boiler, or are simply looking for cheaper heating bills, then any of the air source heat pumps we’ve compared would be a good choice.
With the Samsung and Mitsubishi appliances able to operate in temperatures as low as -25°C they are well worth considering, so you know that you’ll have hot water no matter the weather. If the low operating temperatures of the Samsung EHS Monoblock and Mitsubishi Ecodan Monobloc appeal to you then it’s worth noting that the Samsung model just wins in terms of efficiency with an A+++ rating.
