Mitsubishi Ecodan Air Source Heat Pump

Air Source Heat Pumps (ASHP)

While there is a great deal of domestic and commercial heating options, one of the most traditional is an Air Source Heat Pump, that simply extracts thermal energy from the air outside, and delivers it into your property. 

This energy can be used for providing warm water within a building. Below we have outlined all the details regarding ASHP’s and how Wise Energy can help you if you’re thinking of installing one in your home or place of business.

How do Air Source Heat Pumps work?

down-arrow  Based on the same technology, heat pumps extract thermal energy from the air outside the property

down-arrow  A working fluid passes through the first heat exchanger, which contains an evaporator. This takes heat from the air and turns it into a gas

down-arrow  The gas is then compressed to force a raise in temperature

down-arrow  A second heat exchanger is used to feed through the compressed gas, which heats a working fluid. This now hot fluid supplies a traditional heating system if required

down-arrow  Finally, the gas is fed through an expansion valve which releases the heat, reducing pressure and temperature. The hot gas is condensed and turned back into a cool liquid. The cycle can then be repeated

Are Air Source Heat Pumps Efficient?

An ASHP is known for being super-efficient, given that it is 5 times more efficient than a traditional heating system that uses electricity or fossil fuels. The environmental impact is also hugely reduced given that it is simply extracting heat from the air.
