Air Source Heat Pumps from Dyson Insulation

How does a Heat Pump work?

Heat Pumps are effective solutions to heating applications for all types of dwelling. This is technology has been in used for decades providing safe and reliable heating at affordable prices.

Reserves of conventional fossil fuels are finite and emissions of carbon dioxide and other greenhouse gases increasing add to the effects of climate change. As a low carbon technology heat pumps can reduce the carbon dioxide emissions so reducing the carbon footprint.

The Basic Principle of a Heat Pump

Useful heat can be found in the air outside, in the ground and even in water, even on the coldest days there is sufficient heat available to warm our homes and it’s FREE. All we have to pay for is the cost of the unit to recover the heat and the units running cost.

How does it work?

Well at the heart of the modern heat pump is a refrigeration unit which when the refrigeration cycle is reversed it becomes an efficient provider of heat.

Heat is absorbed into the unit’s heat exchanger from, either the air around it or from the ground/ water sources. This heat exchanger is filled with a refrigerant fluid which has the ability to boil from a liquid to a vapour and then back into a liquid. Using this principle the fluid in the heat exchange passes through a sealed compressor which because of the increase in pressure on the fluid causes the fluid to boil turning it into a vapour. The vapour then passes through a evaporator heat exchanger where the heat absorbed in the vapour is released to be transferred to the heating system within the dwelling the temperature at this point could be 45 to 60 degrees depending on the design of the unit. The vapour as it releases its heat reverts back to a fluid and the proceed continues.
