Air Source Heat Pumps (ASHP)
What is an Air Source Heat Pump?

Air source heat pumps (ASHPs) absorb heat from the outside air. They look the same but do the reverse of an air conditioning unit you would see abroad. There are two types of ASHP:

1. Air to Air Heat Pump – absorbs heat energy from the outside air and then transfers it directly into your home through a cassette fan (the same as an air conditioning unit). This type of pump is ideal to heat a room or small indoor space but not a home. With this type of system, you CANNOT apply for Renewable Heat Incentive payments.

2. Air to Water Heat Pump – absorbs heat energy from the outside air and then transfers it via a traditional central heating system with radiators and hot water cylinder to provide both heating hot water for your home. Greener Energy Group supply Air to Water heat pumps and you CAN claim the Renewable heat incentive with this system as it is heating all your home.

How does an Air Source Heat Pump work?

Heat energy is delivered from the air to the refrigerant which has a very low boiling point. This happens in the evaporator. The refrigerant changes from a liquid to gas and passes in the compressor where it is pressurised. The increase in pressure increases the temperature. Heat is then delivered to water at the condenser ready to be distributed to your hot water tank, radiators or underfloor heating. The refrigerant passes through an expansion valve where it drops in temperature. It becomes liquid once more ready to start the process again.

How efficient is an air source heat pump?

One of the many great benefits of your air source heat pump is that it is an incredibly efficient form of heating. They can exceed 350% in terms of efficiency simply because they transfer heat rather than work to generate it. By having larger radiators and underfloor heating, you can maintain this level of efficiency as your heat pump doesn’t have to work to such high temperatures. The lower the temperature water flows through your radiators, the greater the efficiency.

With an Air Source Heat Pump, for every unit of electricity you put in, heat pumps have the potential to produce 4 units of heat. By comparison to other forms of heating, electric heaters work at around 100% efficiency, meaning that one unit of electricity produces one unit of heat. A brand-new oil or gas boiler will only work at just over 90% efficiency.

In a simple comparison:

With an Air Source Heat Pump, for every £1 spent with an Air Source Heat Pump you will get up to £4 worth of heat.

With a brand-new boiler, for every £1 spent you will only get around 90p worth of heat.

How is the heat pump efficiency measured?

The efficiency of your air source heat pumps is measured by the Coefficient of Performance (COP). This is the ratio of output compared to the required input. For example, a CoP of 3 means your heat pump produces 3 units of heat energy for every 1 unit of electricity it consumes. CoP only measures the efficiency of the heat pump and not the system in full over the year. Seasonal Performance Factor (SPF) takes into consideration the design of the heating system and performance over the year.

How noisy is a heat pump?

Older models were slightly louder, but the latest models are very quiet and range from between 50 and 70 decibels. What does 50 decibels sound like? To give an example of everyday noises in decibels: Breathing = 10, Whispering or Rustling Leaves = 20, A Rural Area Background Noise = 30, A Library or Bird Calls = 40, Conversation at Home = 50, Conversation in an Office = 60, Vacuum Cleaner = 70, Dishwasher = 80

How long does the installation take?

The average installation takes between 3 and 4 days depending on how many radiators are being installed or swapped. On the first day of the installation a new hot water cylinder is installed so that you don’t go without hot water. We also supply potable heaters to make sure you also don’t go without heat. As with any new central heating system there is slight disruption, however the comments we receive back from our customers (that can be viewed on trustpilot.com) is that after the installation “they wouldn’t have known we were there”.

Do I pay VAT?

Yes, the current vat rate on heat pumps is a reduced 5%, however the Government has plans to increase this to 20%. If your system is fully fitted before any changes take effect, then you will still benefit from the reduced rate and save 15% on the full installation costs.

What is the Renewable Heat Incentive (RHI) and is it Means Tested?

The Domestic Renewable Heat Incentive (Domestic RHI) is a Government financial incentive to promote the use of renewable heat. Switching to heating systems that use eligible energy sources can help the UK reduce its carbon emissions and meet its renewable energy targets.

This is not a means tested incentive and is open to all homeowners.

Once your system is installed and fully commissioned, we will provide you with the required paperwork for your claim and you will then receive payments every quarter for a seven-year period.

How much income will I receive with the RHI?

The income is based on the heat and hot water demand from an Energy Performance Certificate (EPC). As part of our service we will arrange an EPC. At present the maximum income is around £1,600 per annum and this income is also linked to inflation and will rise year on year.

Will the RHI income decrease over time?

For new future applicants is inevitable that the Government will reduce and eventually stop this scheme the same as they did with the Solar Feed in Tariff. It would be prudent for all homeowners to take advantage of the high pay outs currently on offer before they change, bearing in mind that once you are in the scheme you are “locked in” for seven years and your payments will increase with inflation.
