Heat Pump Installation

Heat your home with energy absorbed from the air around you.

Air source heat pumps absorb heat from the outside air This is usually used to heat radiators, underfloor heating systems, or warm air convectors and hot water in your home.

The benefits of air source heat pumps

Can lower fuel bills, especially if you are using conventional electric heating.
Can reduce your carbon footprint: heat pumps can lower your home's carbon emissions, depending on which fuel you are replacing.
No fuel deliveries required.
Can provide space heating and hot water
It's often classed as a 'fit and forget' technology because it needs little maintenance.
Can be easier to install than a ground source heat pump, but efficiencies can be lower.

Is an air source heat pump suitable for my home?

To tell if an air source heat pump is right for you, there are a few key questions to consider:

Do you have somewhere to put it? You'll need a place outside your house 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.
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 draught proofed well for the heating system to be effective.
What fuel will you be replacing? The system will pay for itself much more quickly if it's replacing an electricity or coal heating system. Heat pumps are not recommended for homes on the gas network.
What type of heating system will you use? Air source heat pumps can perform better with underfloor heating systems or warm air heating than radiator-based systems because of the lower water temperatures required.
Is the system intended for a new development? Combining the installation with other building work can reduce the cost of installing the system.

Costs and savings

Costs for installing a typical system suitable for a detached home range from about £6,000 to £10,000 including installation. Running costs will vary depending on a number of factors - including the size of your home and how well insulated it is.

Savings - will vary depending on many factors, some are outlined below. It is important that the system is controlled appropriately for your needs. Actual savings figures will depend on your exact fuel prices

The heat distribution system: If you have the opportunity, underfloor heating can provide greater efficiencies than radiators because the water doesn't need to be heated to such a high temperature. If underfloor heating isn't possible, then use the largest radiators you can. Your installer should be able to advise on this.
Fuel costs: you will still have to pay fuel bills with a heat pump because they are powered by electricity. The saving you achieve can be affected by the price of the fuel you are replacing and the price of the electricity for the heat pump.
Efficiency of old and new system: the efficiency of the old heating system will affect how much you spent on heating bills previously. If the old heating system was inefficient heating bills could have been high and the difference between the new running costs and the old running costs will be greater, therefore providing a greater saving.
Hot water: if the system is providing hot water as well as space heating: the provision of hot water can lower system efficiencies, therefore making running costs higher.
Temperature setting: if you heat your home to much higher temperatures with a new heat pump system than you did with an old heating system then your home will be warmer, but heating bills could be higher than if you continued with the same heating pattern. It's a good idea to set thermostats to around 18 to 21 degrees centigrade.
Using the controls: learn how to control the system so you can get the most out of it. Your installer should explain to you how to control the system so you can use it most effectively.

To reduce your home's CO2 emissions further, consider using PV solar panels
