    What are the two types of heat pumps?

    • Ground Source Heat Pumps
    • Air Source Heat Pumps

    What’s the difference?

    Air Source Heat Pumps

    The most common type of heat pump is the air source heat pump, which transfers heat between your house and the outside air.

    An air heat pump will extract heat from air outside your property in the same way a fridge extracts heat from its inside.

    Air source heat pumps become less efficient the cooler it is outside, but they can be capable of operating sufficiently in temperatures of -15 C, which is 99.99% of the year in the UK.

    They have fantastic energy efficiency ratings and although they do have some impact on the environment (because they run on electricity), they do not combust fuels directly, so in most cases they provide a fantastic way of lowering your carbon footprint.

    Ground Source Heat Pumps

    A ground source heat pump functions similarly, but it functions by taking the residual warmth from the soil or a water body outside your property and moves it to the inside of the property.

    Ground source, water source or geothermal heat pumps achieve higher efficiencies by transferring heat between your house and the ground or nearby water source. Although they are more expensive to install they generally have lower operating costs because they can rely on more constant source temperatures.

    The ground source heat pumps also have fantastic energy efficiency ratings and although they do have some impact on the environment (as they require electricity to run), they do not combust fuels directly, so in most cases they too, provide a fantastic way of lowering your carbon footprint.

    Best Air Source Heat Pumps and Prices

    What is the price for a heat pump?

    Air source heat pump installation in a typical property usually costs between £4,000 – £11,000.

    This may sound like a big price tag but when you consider that it could be efficiently heating your home for around 20 years with reduced heating bills, it will soon start paying for itself.

    Using the table below you can get a quick understanding of what each of the models has to offer before we go into more detail about each one individually.

    The prices in the table above are estimates and don’t include the cost of installation, which will vary depending on who carries out the work.

    We highly recommend getting quotes from at least 3 different installers to give you the greatest chance of finding the best deal for your home.

    While it might feel that the costs are already beginning to add up, you can begin to make these initial costs back via reduced energy bills and Renewable Heat Incentive payments during the lengthy lifetime of an air source heat pump.

    Hitachi Yutaki S80

    Details: Hitachi’s Yutaki-S80 high temperature heat pump produces hot water up to 80°C thanks to an energy-efficient, secondary Cascade R134a Heat Pump Circuit instead of an electrical element which gives a boost from 45°C to 80°C.

    It will operate all year-round even in temperatures as low as -20°C.

    The Yutaki S80 has an energy efficiency rating of A+++ so will keep energy usage to an absolute minimum.

    It will provide both heating and hot water with a hot water recovery time which is the same as a traditional boiler.

    The S80 is ideal for new builds and replacing boilers in existing homes and even older properties where higher water supply temperatures may be required to keep the house warm.

    It is not intended to work in a hybrid system alongside a back up boiler.

    Comparing air source heat pumps

    When trying to choose the best air source heat pump for your home, there are several key features to consider apart from the price.

    Types of heat pump

    There are two types to choose from: air to water or air to air.

    Air to water heat pumps are the most popular, as air to air only provides space heating and not hot water production.

    There is also a difference between monobloc or split heat pumps which refers to how the system is set up in your home. A monobloc has all of its components (apart from the hot water cylinder in your home) in one compact unit outside the home.

    A split heat pump includes an outdoor with the heat exchanger and refrigerant as well an internal unit inside.

    Most homes in the UK are ideal for a monobloc air to water heat pump, but a split system may be suitable for more complicated installations as it can be installed up to 30m away from the home offering a more flexible installation.


    Air source heat pumps are exceptionally efficient, as for every kW of energy they use, they generate three times as much usable heat.

    While some heat pumps may be labelled with better efficiency ratings than others, it is important to remember that the actual efficiency you achieve will be greatly influenced by other factors like the level of insulation, the outside temperature, and your demand for hot water.


    Air source heat pumps are available in a range of different outputs to suit different sizes of homes.

    It is important to install the right output, but a professional heat pump installer will be able to advise you on this topic.

    Is an air source heat pump right for your home?

    There are many pros and cons of installing an air source heat pump but if you like the sound of enjoying the ways an air source heat pump could be benefiting your home, such as:

    Reduced energy bills

    Air source heat pumps are highly efficient heating systems that have the potential to lower your energy bills.

    RHI payments

    Air to water heat pumps are eligible for quarterly payments over 7 years through the Renewable Heat Incentive scheme.

    Better for the environment

    Heat pumps use only a small amount of electricity to run and are capable of generating significantly less carbon than fossil fuel heating systems.

    Heat your home all year round

    Make use of your air source heat pump all year round even in the coldest UK winters.

    Easy to maintain

    Aside from annual servicing heat pumps a they require very little maintenance and can be left alone to heat your home.

    Long lifetime

    Many can last for up to 20-25 years. That’s around twice as long as a modern boiler.

    However, it is important to note that air source heat pumps are not suitable for every type of home. For an air source heat pump to be effective your home needs to have:

    • A high level of insulation
    • Outside space for the fan unit
    • Large radiators or underfloor heating for maximum heat delivery as heat pumps deliver heat at a lower temperature than boilers
    • A small amount of electricity to operate
    • A hot water cylinder

    To get the best price on an air source heat pump for your home, it is important to compare multiple quotes from different companies.

    This can take time but we can help make your research a lot easier.
