All you need to know about air source heating, including costs of air source heating installation, equipment, labour and time frames.
An air source heat pump can offer the same benefits as a conventional gas or electric heating system by transferring heat from the outside air to a wet central heating system to heat radiators and provide hot water. An air source heat pump works much like a refrigerator in reverse, absorbing heat from the air and transferring it into your home or office. They can also function as a cooling system in hot weather and are usually placed outside where there is adequate space. There are two main types of heat pumps to choose from: air-to-air heat pumps which transfers heat directly into your home, or air-to-water heat pumps which transfer the heat into your central heating system to provide hot water and radiators.
Air source heat pumps offer a low carbon footprint and the pump can even be powered by wind or solar power. They can heat hot water for immediate use or store hot water in a cylinder for later use. Air source heat pumps can deliver heat at a lower temperature and you can potentially receive payments in the UK through the Renewable Heat Incentive. You can save on your energy bills using an air source heat pump and they have an operational lifespan of up to 20 years, plus it only typically takes a few days to install the air source heat pump and all you need to do is clean them every few months and get a technician in once a year to service them. No fuel storage is required either and you can even use them to provide cooling in the summer months!
The main disadvantages of air source heat pumps are that they supply water at a lower temperature so you will need larger radiators to keep rooms at the same temperatures. In fact, air source heat pumps perform much better with underfloor heating or warm air heating than when coupled to larger radiators. So if you are building a new home, it is better to integrate a heat pump with underfloor heating in the planning stage. In the UK right now, gas is so cheap that if you live in a home with mains gas you would not save much, if anything, by installing an air source heat pump. In addition, to reap the most benefit from an air source heat pump you need to have a highly insulated home.
Getting your money back from the cost of installing an air source heat pump will depend on the efficiency of your system and the type of heating fuel you are replacing. Annual savings you can expect in a four-bedroom detached house are around £450 per year if replacing an oil heating system, around £1,800 per year if replacing an LPG heating system and around £1,000 if replacing an electric night storage heating system. With mains gas, there are hardly any savings at all so no payback figures can be calculated. The actual installation costs will differ regionally across the UK, as well as depending on the type of system you choose to install and the size of your home.
The systems prices can vary quite a lot, from as little as £500, up to £7000 - your own cost of a system will likely be proportional to the property in question. The system itself will be the majority of the expense of the project, so the choice of system should be thought over carefully, to ensure that a suitable system is selected that meets the property needs and not paying for unneccessary/excessive additional features.
As an installation will typically take a few days to complete, the expected labour cost would be between £150-£250 per day, depending on factors such as the difficulty of the installation, time taken and where in the country that the work is being completed (as labour rates can vary regionally).
