What is an Air Source Heat Pump?

A Heat Pump is a unit that will be located outside of the property. It takes air in through the pump and boosts it to a higher temperature. The Heat pump does use electricity to power the unit but will use less electricity to power the Heat Pump than the heat it will provide for your property. On average every unit of electricity the Heat pump uses for power it will generate 2-3 units of heat.


*They will require an annual service to be accepted by the manufacturers warranty.

What is the RHI (Renewable Heat Incentive)?

The RHI (Renewable Heat Incentive) is the scheme put in place to financially reward customers who are benefiting from renewable energy sources to heat their properties. There is a separate RHI for domestic and non domestic customers. The RHI is a seven year scheme where you will receive payments every quarter.

Air Source Heat Pumps FAQ

You have already been using a heat pump for decades without realising it.

Your refrigerator using the same basic heat pump technology to remove the heat from the food inside the ‘box’, ejecting it to the outside and keeping the food cold.

A heat pump reverses this process and extracts heat energy from the outside air, ground or water and moves that heat into your home (hence ground source or air source heat pumps).

Using the same ‘vapour compression cycle’ as your fridge to produce heat, the heat pump can take a few degrees of outside heat and upgrade it to provide all the heating and hot water you need.

An air source heat pump, is essentially a ‘box’ that sits outside your home and uses a fan to draw air through the refrigerant piping, where the heat energy is harvested and upgraded.

The heat pump runs on electricity and will ‘convert’ each kilowatt of electrical energy into 2, 3, 4 or more kilowatts of heat energy. This ‘free’ energy taken from the air is replaced each day by the sun and is therefore renewable energy.

There are a number of factors affecting the cost of installation such as the age and size of your property, the levels of insulation and thermal efficiency, the number of rooms and radiators, etc, so it is difficult to give even an average idea of cost, please ask us for more details.

However, installations are eligible for 7 years of payments under the Renewable Heat Incentive, which significantly reduces the payback period. You should also make savings on your energy bill so will notice a difference almost immediately.

And, if you install an ASHP system, this can come with a Metering and Monitoring Package (MMSP) which qualifies for an additional payment amounting to £1,610.

This depends on what system of heating you currently use but even with a gas boiler, you are likely to make significant savings.  For Oil, LPG or direct electric heating the savings could be even greater.

Again, there are a number of factors that will affect this but for a new-build home, the ASHP air source heat pump can be installed in a couple of days.

For a refurbishment, it depends whether your radiators also need replacing, whether your water cylinder needs re-siting, where the outside box will be fitted, etc.

It will also depend on whether you are completely replacing the existing heating system or simply adding an ASHP to work alongside the current heating in a hybrid solution – which more people are doing now. This provides a fairly straightforward way of adding renewable heating (which can still qualify for the Renewable Heat Incentive) whilst minimising the work needed.

ASHP has been manufactured in the UK for more than a decade now and we have invested heavily in R&D to make sure that it is designed specifically for UK conditions.

The system will continue working to maximum efficiency down to -10C and will carry on working to -20C or more, so you can rely on a warm and cosy home even when there is snow on the ground.

The outdoor part of the system does have a fan which draws the air across the internal components and this will make a whirring noise in operation.  The amount of noise depends on the quality of the product and this is where the ASHP ranges we specify excel.

Under Permitted Development regulations, an air source heat pump noise level must not exceed 42dB(A) 1m away from a neighbour’s nearest room.

With our selection of quiet air source heat pumps, these can be located much closer to the your neighbour’s property and pass any planning if required.

Some of the latest models offer superb style, market-leading energy efficiency and sound levels and are 3 times quieter than previous models virtually eliminating planning restrictions.

Should you have a very large property that requires more than one heat pump, planning will be required.

ASHP already comes with sophisticated smart controls that allow you to monitor and control your heating from anywhere, and allows you to see and change settings from your sofa, your office, or the poolside.

In addition to this, you are able to see how much energy you are using, allowing you to spot trends and vary your heating to match your needs with maximum efficiency and minimum cost.

These advanced controls also mean that we can access your system remotely to check your system is running as efficiently as possible and troubleshooting if ever necessary.

Contact us and we can arrange for this. In the meantime, please have a look at the various links on our website.
