Heat your home with energy absorbed from the air around you

Air Source Heat Pumps work in exactly the same way as their Ground Source counterparts – the only difference being that the source of the heat comes from the air around the system and not from pipes deep underground. They are cost-effective and easy to fit providing a renewable, clean source of heat all year round and significant reduction in carbon emissions. These systems also work well with underfloor heating in addition to traditional radiator systems.

How does it work?

Very much in the same way to Ground Source Heat Pumps – except no boreholes are needed – therefore no digging is required. The Air Source Pump draws in air from the surrounding environment and absorbs heat from it. This heat can then be used to warm water for radiators or underfloor heating systems, or to warm the air in your home. In effect the process is very similar to the technology contained within refrigeration units. The outside air is drawn in which is then run over a series of hot pipes and an evaporator, which works like a refrigerator in reverse to heat up the air, with cool air produced as a by-product. This results in very hot air circulating within the system which is then at a perfect temperature to heat water and your home. Air Source Pumps work all year round – in fact, they are more efficient during cooler weather as the air is more dry – as there is less moisture in the air the system doesn’t need to defrost. The pump is situated on your property, somewhere with plenty of space around it to enable it to consume the correct amount of air. Usually pumps are external, attached to a wall or placed on the ground.

The efficiency of Air Source systems is measured by a Coefficient of Performance (CoP) – which relates to the amount of heat they produce compared to the amount of electricity needed to run them. A typical CoP for an air source heat pump is around 3.6 – which can be compared to a CoP of 1.2 for a traditional, less economic radiator gas system.

What are the benefits?

air-source-heat-pumpAir Source Heat Pumps offer an advantage over ground source heat pumps for domestic installation because they require less space to install. Instead of requiring the installation of buried underground coils, Air Source systems can be fitted using much less space and are therefore much more suited to an urban home or retrofit situation. Like Ground Source Heat Pumps, Air Source systems will save you money in the long term and offer a sustainable and economical alternative to propane, oil or natural gas. Air Source is also a good alternative for those without the space for boreholes or who can’t accommodate digging in or around their property.

Financially, you should see a significant reduction in your fuel bills – as highly-efficient Air Source

Heat Pumps run on electricity, so there’s no need to pay for gas, oil or solid fuels to heat your home.

You will also cut down on wasted electricity by heating your home with an economic, energy- efficient Air Source Heat Pump – as they are much more cost-effective and ‘green’ when compared with electric radiators.

Is an Air Source Heat Pump system right 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 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. If you’re unsure, we will assess this for you during our initial consultation with you and ensure your property’s suitability before work starts.

Is your home well insulated?

Since Air Source Heat Pumps produce less heat than traditional boilers, it’s essential that your home is insulated and draught proofed well for the heating system to be effective. We will complete a thorough audit of your home prior to your decision to work out the amount of energy wastage and usage and assess whether investing in better insulation might improve the efficiency of your new system.

What fuel will you be replacing?

The system will pay for itself much more quickly if it’s replacing an electricity, oil, Liquid Petroleum Gas (LPG) or coal heating system than a gas one. It’s important to consider the projected returns and weigh them up against your expectations – we specialise in producing an accurate forecast for you based on your current situation to help you make the right decision.

What type of heating system do you want?

Air Source heat pumps are much better at powering underfloor heating systems or warm air heating than radiator-based systems – so it’s well worth considering whether you should replace your old system on investing in a renewable energy source to gain the full benefit of the Air Source installation.

Is the system intended for a new development?

Combining the installation with other building work can reduce the cost of installing the system – but Air Source systems are a good option for retrofits or existing modern buildings because of their less intrusive nature and ease of fitting.

Costs, maintenance and timescales

The installation time for Air Source systems is around a week. Maintenance and upkeep costs are fairly low – in line with the manufacturer’s seven year warranty covering the pump we will carry out an annual service to ensure that the pump and system it supplies are working efficiently and check the fluid levels in the system. Our ten year insurance-backed workmanship warranty also covers any routine maintenance work.

What’s the process?

Following an initial conversation we complete a full assessment of your property, including a heat loss calculation and performance certificate to ascertain your current energy usage and efficiency.

This helps us to estimate how much energy (and money) you could save through the implementation of an Air Source system. We then send a quotation based on our findings. Once you decide to go ahead, we simply fit the pump and switch your system over from your old energy supply to the Air Source. On completion you will receive a detailed handover document which includes a checklist of completed tasks and important information should you decide to apply for an additional grant or would like to have any further installations carried out in future.
