Air Source Heat Pump
Air Source Heat Pumps concentrate heat from the air and use it to heat your hot water cylinder, radiators or underfloor heating.
We recommend Air Source Heat Pumps for people with well-insulated homes. They are also popular with self builders and developers building new build homes as they integrate well with underfloor heating. Designed well, an Air Source Heat Pump will provide all the hot water and heating you require 365 days a year.
The quality and reliability of Air Source Heat Pumps vary enormously. We only offer a range of Air Source Heat Pumps with proven track records and robust guarantees. Combined with our expert design and installation service this gives us full confidence in your heat pump’s performance.
How Do ASHPs Work?
Step 1- Evaporation
The energy is absorbed from the air by large fans on the unit that draw the air in, before passing over a heat exchanger that sits directly behind the fan. Through the heat exchanger flows a liquid refrigerant and as the ambient temperature stored in the air comes into contact with the heat exchanger, the liquid refrigerant heats up. This process increases the temperature of the refrigerant changing it from a liquid to a vapour.
Step 2- Compressor
The warmed-up refrigerant is then passed into a compressor where it is condensed and its temperature is raised further by an electrically driven compressor to a point where it is ready for distribution around the central heating system of a home.
Step 3- Condenser
The condenser then releases this heat energy into the water used in your heating and hot water system.
Step 4- Expansion Valve
The cooled refrigerant turns back into a liquid and the process starts again.
Benefits of an ASHP
You reduce your Carbon Footprint
ASHPs are low carbon, environmentally friendly heat source
Highly efficient, transferring around three times more energy into a home as heat than it uses to extract it from the air.
For every 1kW of electrical energy used to power the air source heat pump, 3-4kW of heat energy is returned
ASHPs Can also be used for cooling
Capable of also providing active cooling which saves time, money and space compared to installing a seperate
Little outdoor space required
This means an air source heat pump system is suitable for most urban properties
Air source heat pumps are relatively quick to install, require little maintenance and have a long lifespan of around
ASHPs are safer than fossil fuel-burning systems. An air source heat pump system is powered entirely by electricity
and is combustion-free
Is it possible that my Heat Pump will work with existing radiators?
Yes, Heat Pumps can be connected to your existing radiators, underfloor heating, water tank etc. Your systems
compatibility will be checked during our home survey.
Are ASHPs noisy?
The Air Source Heat Pump systems all fall into the permitted development category. Fortunately, this means they
are not noisy.
What is the lifetime of an ASHP?
On average the lifespan of a Heat Pump is over 20 years.
What will happen to my oil tank?
Having an Air Source Heat Pump means you will no longer require oil to heat your home.
What other benefits come from installing an ASHP?
With a heat pump, you don’t need to worry about a flue, oil tank or gas connections. Plus you won’t need to
pay in advance to store fuel.
Does an ASHP require any maintenance?
There is only a minor maintenance jobs that fortunately the owner can do themselves. It includes cleaning
the outdoor unit and keeping it free of debris. It is also important to have your system serviced once a year.
