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.

An average installation is around £12,500. We will be happy to provide you with a personalised quote.

How much will I save on running costs?
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.

There are a number of factors that will affect this however on average an air source heat pump can normally be installed in two to three days.

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

The average lifespan of a heat pump is 15 to 20 years if they are constantly being monitored and preventive maintenance is performed. We can help you with an annual service plan

Yes. The heat pump dehumidifies in cooling mode and in the heating mode, such a function is not needed as the water circulating through the pipes removes the humidity.

Yes, it is provided that the house is well insulated and the system works well.

Installations generally can take up to two to three days.

Commercial installations can take longer, depending on the size of the site and the specific requirements of your business.

FIT (Feed In Tariff) is the government-backed scheme which means your electric supplier (eg EON, N-Power, EDF, Utility Warehouse etc) will pay you for every unit that your system generates, whether you use it or if it goes back in to the grid. The Feed in Tariff scheme ran from April 2010 until March 2019 and was designed to reduce the subsidy in line with the reduced installation costs. Now that Solar PV installation prices are low enough there is no continued need for a subsidy so the Government finished the scheme in March 2019.
