Air Source Heat Pump

What are Air Source Heat Pumps and how much can they save your business?

What is an Air Source Heat Pump ?


  • One of the most commonly used and simplest of heat pumps to install
  • It uses the outside air to heat your water to high temperatures, either for hot water use or space heating, through a radiator or underfloor heating system
  • Can work at temperatures as low as -25°C¹

Why Install an Air Source Heat Pump?

  • Save up to 50% on your energy bills
  • Improve your heating efficiency – With an Air Source Heat Pump 1kW of electricity will produce up to 4kW of heat energy, reducing your carbon footprint and saving you money
  • Reduce your carbon emissions and help in the fight against climate change
  • Earn through the government Renewable Heat Incentive

How Does it Work?

  • By efficiently supplying hot water to the radiators at a constant temperature Air Source Heat Pump’s provide a controlled level of warmth year-round and all the hot water you need.
  • An Air Source Heat Pump is based on one simple principle, heat transfer – using a small amount of energy to transfer low-grade heat from the air to high-grade heat, heating water to high temperatures. Essentially transferring heat from a ‘free heat source’ like the air to a ‘heat sink’ like your home.


The Vapour Compression Cycle

  1. The outside air is pumped across refrigerant filled coils, causing the liquid refrigerant to increase in temperature and produce hot gas.
  2. This hot refrigerant gas then enters the compressor where its temperature increases further as a result of the compression process – much like a bicycle pump heats up during its use.
  3. The hot refrigerant gas is then condensed turning back into a liquid. This, now high-temperature water, is distributed via the buildings heating circuit to provide you with hot water and heat your home.
  4. This process is repeated to provide a constant temperature to the property.

Frequently Asked Questions

Air Source Heat Pumps can reduce your annual heating and hot water bills by up to 50% against fossil fuel alternatives and it often pays for itself within the grant period set out within the Renewable Heat Incentive (20 years of payments for a non-domestic property).

However, each and every property is different so upfront cost, bill reduction and your ROI is never going to be a one answer fits all. The best way to find out how much an Air Source Heat Pump can reduce your heating and hot water bills is to speak to us directly for a free no obligation quote.

What is the Renewable Heat Incentive?
The RHI is a Government backed scheme which pays the owner of a renewable technology, such as a heat pump, for generating renewable energy on site. To qualify for these quarterly payments, which last 20 years, you will need to use an MCS accredited company – such as Ecovision – and ensure your MCS accredited product is installed to MCS standards.

The MCS (Microgeneration Certification Scheme) is there to ensure the system is safely installed by professionally qualified installers and performs to the standards required by the Government.

How Long do Air Source Heat Pumps Take to Install?
On average Ecovision can fully install an Air Source Heat Pump in less than 4 days and, if required, we can partially replace or install a complete radiator or underfloor heating system when required.
Do I Need to Coordinate Other Trades on Site?
No, Ecovision can undertake the entire installation, providing the complete design, supply, installation and commissioning of the system, without any need for third parties or subcontractors.

During Ecovision’s many years of business, we have found the biggest issue for customers is ensuring that everyone knows what and when their responsibility starts and ends. We have found that by managing the installation from start to finish we ensure that we remain in control of the whole process as well as being entirely responsible for the successful completion of the installation with our in-house installers reporting directly to Ecovision.

Do Air Source Heat Pumps Require Alot of Maintenance?

Generally, Air Source Heat Pumps require very little maintenance, as they are a sealed unit, much like your fridge. Though it is recommended that you inspect and clean your Air Source Heat Pump annually, clearing any build-up of leaves or debris from behind the unit.

Ecovision can complete this task as part of an annual service, leaving you with absolutely no maintenance requirements.
