RENEWABLE HEATING

Air Source Heat Pumps

A

 
Our top-performing Air Source Heat Pumps take energy from the air and convert this energy into heat.
 
Sunlite is a supplier of air-source heat pumps, our range of air source heat pumps are available from 5kW to 16kW. We can supply the pump only, or a complete pack and a storage cylinder containing everything required for the heat pump to work as a heat source in your project. We are merchants of Daiken and world heat cylinders.
 
Air Source Heat Pumps can be used to heat your home and water. They move existing heat energy from outside into your home. This makes them more efficient since they deliver more heat energy than the electrical energy they consume. As a result, heat-pump systems typically cost less to run than a traditional heating system.

What are ASHP’s

W

Air source heat pumps are low-carbon, renewable energy sources. Their environmentally friendly technology can heat your home using natural ambient air from outside, even in cold weather.

There are two types of air-source heat pumps, air-to-water and air-to-air. Air-to-water systems are the most common as they extract heat energy from the air outside and use it to heat water stored in a tank. In contrast, air-to-air pumps use fans to distribute warm air around your home and cannot heat water.

How do they work?

H

Air source heat pumps use the same technology as your refrigerator, in reverse. 

  • Evaporator – as the air flows over the network of tubes filled with a refrigerant, this refrigerant will gradually heat and transform from a liquid to a gas (vapour).
  • Compressor – an electrically powered compressor compresses the refrigerant vapour, increasing the temperature so that it’s high enough for use.
  • Condenser – This warm refrigerant passes into a heat exchanger, which condenses the vapour into a high-temperature liquid. This liquid will move through your chosen heating system, e.g. underfloor heating, to warm your home.
  • Expansion Valve – Once the liquid refrigerant passes through the expansion valve, its temperature & pressure will slowly decrease, and the cycle repeats.

Renewable, Green energy

R

It’s more important now than ever to look for more sustainable living methods. By installing a heat pump, you can help reduce your carbon footprint and cut down your energy bill.

✔    A little goes a long way – heat pumps only need a small amount of electricity to complete their energy absorption & distribution process. 

   Over 300% energy efficient – for every 1kWh it uses, AHSP’s produce and emit over three times that.

✔    Reduce your carbon footprint – air source heat pumps are a form of low carbon heating as they use outside air to heat your home.

    Long-Lasting – air source heat pumps take two days to install but can last for longer than 20 years.

✔   Low maintenance – requires minimal cleaning every two months and an annual service.

 
 
 
 

Is there funding for Air Source Heat Pumps?

I

Yes, there is funding available. In October 2021, the Government unveiled the Boiler Upgrade Scheme. Families will receive £5,000 per household to change their gas boiler to a heat pump. This scheme will be active from April 2022 and run for three years, ending in 2025.

With the average installation price starting from £7,000, this scheme makes ASHP’s a great, cost-effective heating solution. In addition, the eco-friendly scheme reduces the average installation fee to just £2,000, making it cheaper than a new gas boiler.

Will it save me money?

W

While initial installation costs may seem high, don’t let this discourage you. You can claim £5,000 using the government’s Boiler Upgrade Scheme. In addition, you may be able to spread the costs into manageable, interest-free monthly payments.

Also, air-source heat pumps offer cheaper running costs compared to your standard boiler, which could save you between £455 to £485 a year. 

Furthermore, by installing a heat pump, you may become eligible for the Renewable Heat Incentive Scheme. After using your air source heat pump, you will receive payments spread across seven years. This is part of an incentive for the British population to switch to more sustainable, renewable heating systems.

Find out how much you could receive using the Government’s Renewable Heat Incentive calculator. Be sure to read further details on the scheme and eligibility requirements before applying. Please note that applications for the RHI scheme close on 31st March 2022.

Can a Air Source Heat Pump replace my boiler?

C

Absolutely. In most cases, an air source heat pump can provide all the heating and hot water required for your home. As it uses 65-70% of ambient air found naturally around your home, it is a far more economical solution than the standard gas condensing boiler.

The ideal home will be well-insulated with a garden to accommodate the pump itself. Air source heat pumps work best alongside underfloor heating systems or radiators with a large surface area. You must also have adequate internal space for the hot water cylinder.

The heat is emitted at a lower temperature than gas and oil boilers, so you may need to run the heat pump for longer periods to reach your desired temperature. However, a well insulated home will reduce this time significantly.

 

What are the running costs?

W

For every 1 kWh of electricity, air-source heat pumps can produce 3 kWh of heat

F

For every 1 kWh of electricity, air-source heat pumps can produce 3 kWh of heat. The average UK heat demand (12,000 kWh) divided by three results in a requirement of 4,000 kWh of electricity. 

If this electricity is priced at £0.13 per unit, it will cost you £520 to run per year, which averages at just £43 a month. A fraction of the cost compared to the average monthly bill of 3 bedroom house, currently standing at £97.
