Air Source Heat Pump

Heat your home with energy absorbed from the air around you.
Air source heat pumps absorb heat from the outside air. This heat can then be used to heat radiators, under floor heating systems, or warm air convectors and hot water in your home.

An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as -20° C. Heat pumps have some impact on the environment as they need electricity to run, but the heat they extract from the ground, air, or water is constantly being renewed naturally.



The benefits of air source heat pumps

  • Proven Technology

    Heat pumps have been around for years. They have been used for years in countries such as, Sweden, Switzerland, Germany, Northern America and many more. Providing hot water, heating and air conditioning all year round. With many different manufacturers providing different Heat pump systems, we're sure we can find the right system for your needs and requirements, from bungalows to large houses alike.
    • Fits Your Current Heating System

      Some heat pumps can achieve flow temperatures of 80 degrees and therefore connect straight to your existing heating system/ radiator set up, Heat pumps are most efficient when running at lower flow temperatures so work best when linked to wet under floor heating or low temperature radiators, we can advise and install under floor heating.


    • Great Savings On Your Existing Bills


 Heat pumps produce great savings on existing heating and hot water bills, especially for those off the mains gas grid. The exact percentage depends on a range of variables, type of heat pump, previous fuel source, size of premises and insulation levels. Air source heat pumps run on electricity and therefore will depend on the price of electricity as to the amount you will save. ASHP's  work very well together with P.V. (Photovoltaic solar panels), making savings even greater.



    • 25 Year Life span, Low Maintenance

      Heat pumps have a 25 year life span whilst maintaining their efficiency if installed to an accredited standard, they require very little maintenance to keep the efficiency up.
    • Extremely Efficient

      With a high efficiency condensing gas boiler, for every kWh of energy you put in, you can expect to get 0.9kWh to 0.98kWh of heating out. With heat pumps, for every kWh of energy you put in, you get 1.82kWh to 3kWh of heat in return, so they’re up to 300% efficient and provide heating and hot water more energy efficiently.
    • Reduces Carbon Emissions

      Depending on your choice of heat pump, you will reduce your carbon emissions by between 40% and 75%. Heat pumps which are powered by electricity from a green, zero-carbon supplier, will deliver all your home and hot water heating without emitting any carbon whatsoever.
    • Generous Grants Available

      For home-owners using government (MCS) accredited designers and installers to install heat pumps, substantial grants are available, and for businesses, schools, community and not-for profit organisations, a large range of grants, loans and incentives are now coming on stream.

How do air source heat pumps work?

Heat from the air is absorbed at low temperature into a fluid. This fluid then passes through a compressor where its temperature is increased, and transfers its higher temperature heat to the heating and hot water circuits of the house. There are two main types of air source heat pump system:

  • An air-to-water system distributes heat via your wet central heating system. Heat pumps work much more efficiently at a lower temperature than a standard boiler system would. So they are more suitable for under floor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time.
  • An air-to-air system produces warm air which is circulated by fans to heat your home. They are unlikely to provide you with hot water as well.

Is an air source heat pump suitable for me?

  1. Do you have somewhere to put it?
    You'll need a place outside your home where a unit can be fitted to a wall or placed on the ground. It will need plenty of space around it to get a good flow of air. A sunny wall is ideal.
  2. Is your home well insulated?
    Since air source heat pumps work best when producing heat at a lower temperature than traditional boilers, it's essential that your home is insulated and draft-proofed well for the heating system to be effective.
  3. What fuel will you be replacing?
    The system will pay for itself much more quickly if it's replacing an electricity or coal or oil heating system. Heat pumps may not be the best option for homes using mains gas.Is the system intended for a new development?Combining the installation with other building work can reduce the cost of installing the system.


Costs, savings and earnings


Installing a typical system costs around £6,000 to £10,000. Running costs will vary depending on a number of factors - including the size of your home, and how well insulated it is, and what room temperatures you are aiming to achieve.


How much you can save will depend on what system you use now, as well as what you are replacing it with. Your savings will be affected by:

  1. Your heat distribution system
    If you have the opportunity, under floor heating can be more efficient than radiators because the water doesn’t need to be so hot. If under floor heating isn’t possible, use the largest radiators you can. Your installer should be able to advise on this.
  2. Your fuel costs
    You will still have to pay fuel bills with a heat pump because it is powered by electricity, but you will save on the fuel you are replacing. If the fuel you are replacing is expensive you are more likely to make a saving.
  3. Your old heating system
    If your old heating system was inefficient, you are more likely to see lower running costs with a new heat pump.
  4. Water heating
    If the heat pump is providing hot water then this could limit the overall efficiency. You might want to consider solar water heating to provide hot water in the summer and help keep your heat pump efficiency up.
  5. Using the controls
    Learn how to control the system so you can get the most out of it. You will probably need to set the heating to come on for longer hours, but you might be able to set the thermostat lower and still feel comfortable. Your installer will explain to you how to control the system so you can use it most effectively.



You may be able to receive payments for the heat you generate using a heat pump through the government’s Renewable Heat Incentive (RHI). This scheme should be launched in Spring 2014. For systems installed since 15th July 2009 you may be able to get help with the installation costs of a new air source heat pump through the Renewable Heat Premium Payment scheme. Air to water heat pumps satisfy all your heating and domestic hot water requirements right through the year even on the coldest of days.

RHI tariff proposals announced.

Key Proposals within the consultation are:

Ø  Indicative tariff ranges for air source heat pumps 7.2p/KWh  that are MCS certified and meet relevant required standards

Ø  Payments for householders over seven years for each KWh of heat produced for the expected lifetime of the renewable technology and based on deemed heat usage

Ø  Tariff levels set to provide a better return for householders living off the gas grid

Ø  Budget management system similar to the one introduced for the Feed-in tariffs scheme

What is the RHI?

The Renewable Heat Incentive (RHI), is a financial incentive scheme for renewable heat generation that will help the UK reduce carbon emissions, and hit EU renewable energy targets. The Department of Energy and Climate Change (DECC) is responsible for the policy and regulations underpinning the scheme.


The Renewable Energy Consumer Code (RECC) sets out standards members must meet, as a way of ensuring that companies provide high standards of service to customers

The benefits of Air Source Heat Pumps

Ø  Lower Fuel Bills – Air Source Heat Pumps run on electricity, so there is no need to pay for gas, oil or solid fuels for heat (or to be located on the gas grid).

Ø  Less Electricity Use – Heating with an Air Source Heat Pump is much more efficient than using electric radiators.

Ø  They Save Space – An Air Source Heat Pump system is compact, and requires no storage for fuel.

Ø  ASHPs Become More Renewable As The Grid Decarbonises – If the pump is run by renewable electricity, ASHPs can be entirely renewable sources of energy, if operated by renewable electricity.
