Air source heat pumps
- Like ground source heat pumps, air-to-water ASHPs work better with underfloor heating systems. If underfloor heating is not possible, large radiators will be installed. This is because the heat generated by the heat pump is not as high as that produced by a conventional boiler, so a larger surface area is needed to achieve similar temperatures in your home.
- Heat pumps can save you a lot more on your heating bills if you’re replacing an electric, oil, LPG or coal system, rather than gas.
- A well-insulated house is essential to best optimise the heat generated by your ASHP – otherwise the heat the pump is generating escapes more easily.
- Once in place, the heat pump should require little maintenance, we will look after it for you
- Air-to-water heat pumps qualify for (RHI) which means that you will get a payment for installing a greener form of energy.Air source heat pump costs and savings
- ASHPs are cheaper than ground source heat pumps. The Energy Saving Trust (EST) estimates that the cost of installing a typical ASHP system ranges between £9,000 and £11,000 but we will be able to give you an exact quote after survey as price is dependent on the size of the pump and the install.
- The payback period (the time taken to recoup the cost of the system in energy savings) depends on how efficiently your system works, the type of system you’re replacing, whether you can get money with the RHI and how you’ll be using the heat generated from the pump.
Pros of air source heat pumps
- Air source heat pumps can generate less CO2 than conventional heating systems.
- They are cheaper than ground source heat pumps and easier to install, particularly for retrofit, although their efficiency can be lower than with ground source heat pumps.
- ASHPs can provide heating and hot water.
- They require very little maintenance.
- Some can be used for air conditioning in the summer.
- ASHPs can qualify for the RHI, a financial incentive that pays you to produce heat through clean technologies.
- You need to use electricity to power the pump which circulates the liquid in the outside loop, but for every unit of electricity used by the pump, you get between three and four units of heat, roughly translated that means it could be up to 400% efficient – making this an excellent way to heat your property
