Heating your home & hot water just got easier, cheaper and more eco friendly
Air Source Heat Pumps
Energy efficient
Air source heat pumps can generate less CO2 than conventional heating systems.
Easy to install
They are easier to install than ground source heat pumps, particularly for retrofit.
RHI approved
A financial incentive that pays you for generating your own heat through renewable technology.
RHI is the UK Government financial incentive to promote the use of renewable heat
You are issued payments which are meant to help offset the cost of installing and running the system
The UK’s target to reach 12% of renewable heat sources by 2020 is incentivised by the RHI
First payment will be made three months after the date you applied and at the tariff rate applicable at that date
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 systems:
Air-to-water
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. This makes them more suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time.
Air-to-air
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?
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 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.
- 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 well insulated and draught-proofed for the heating system to be most efficient.
- 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 may not be the best option for homes using mains gas.
- What type of heating system will you use? Air source heat pumps can perform better with underfloor heating systems or warm air heating than with 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.
Savings
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:
- Your heat distribution system. If you have the opportunity, underfloor heating can be more efficient than radiators because the water doesn’t need to be so hot. If underfloor heating isn’t possible, use the largest radiators you can.
- 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.
- 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.
- 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.
- Using 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. Our installer will explain to you how to control the system so you can use it most effectively.
