Air Source Heat Pumps
Heat your home with energy absorbed from the air around you.
Futureplumb are always dedicated to reducing the country’s carbon footprint and helping you save money. Air source heat pumps are perfect for saving money and saving energy. Air source heat pumps absorb heat from the outside air, which can then be used to heat radiators, underfloor heating systems, warm air convectors and provide hot water in your home.
An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as -15° C, which means that you can still use it in the winter. Heat pumps have a small impact on the environment as they need electricity to run, but the heat they generate from the ground, air and water is constantly being renewed naturally.
We have listed below the benefits of an air source heat pump:
- It could lower your fuel bills, especially if you are replacing conventional electric heating
- you could be provided with an income through the government’s Renewable Heat Incentive (RHI)
- could you lower your home’s carbon emissions, depending on which fuel you are replacing
- you don’t need fuel deliveries.
- You can heat your home and provide hot water.
- Air source heat pumps need very little maintenance – they’re called ‘fit and forget technology’
- They are easier to install than a ground source heat pump, though efficiencies may be slightly lower.
An air source heat pump is suitable for most people, however before purchasing one, there are a few things you should consider. You’ll need a place outside your home where a unit can either 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. Your home will need to be well insulated in order for the heat pump to be most effective.
Costs and savings.
A typical air source heating installation costs around £7,000 to £14,000. Running costs depend in the size of the home and how well insulated it is. The below table shows how much you will save a year when replacing an existing heating system in an average four-bedroom detached home with an average ASHP installation:
|Existing system||Savings per year||RHI income per year|
|Gas older (non-condensing)||£/year||£290 to £435||£805 to £1,280|
|Carbon dioxide/year||1.4 to 2.4 tonnes|
|Electric (old storage heaters)||£/year||£550 to £1,060||£805 to £1,280|
|Carbon dioxide/year||5.8 to 10.5 tonnes|
|Oil older (non-condensing)||£/year||£545 to £880||£805 to £1,280|
|Carbon dioxide/year||2.3 to 3.6 tonnes|
|LPG older (non-condensing)||£/year||£1,160 to £1,845||£805 to £1,280|
|Carbon dioxide/year||2.1 to 3.4 tonnes|
|Coal||£/year||£475 to £835||£805 to £1,280|
|Carbon dioxide/year||6.4 to 10.6 tonnes|
