Heat Pumps
How does a Heat Pump work?
Heat Pumps are effective solutions to heating applications for all types of dwellings. This 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 increasingly add to the effects of climate change. 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?
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. As the vapour releases its heat it reverts the vapour as it releases its heat reverts back to a fluid and the proceed continues.
Using a Mitsubishi Ecodan unit Dyson’s can use FREE energy from the outside air, to provide space heating and hot water a low carbon alternative to a traditional gas or oil that will dramatically reduce your home’s running costs and it’s co2 emissions.
The Ecodan uses heat pump technology which takes the warmth out of the outside air and raise’s it up to 55 degrees it then transfers it to inside your home to heat your heat emitters, (either radiators, under floor heating or a mixture of both) and to provide hot water.
This provides constant levels of comfort and plentiful hot water for much less money
Traditional boilers and radiator systems work by producing on-off bursts of heat to maintain the desired room temperature. Ecodan is different as it supplies water to the radiators at a lower, yet more constant temperature.
You still set your thermostat to the same temperature but the beauty of Ecodan means that you’ll enjoy a constant, more controlled level of warmth and hot water throughout the day and night for a lot less money.
The Ecodan system is designed to operate at the optimum efficiency level at any time of the year, even at temperatures as low as -20 C.
The technology automatically regulates the system to ensure that you never use more energy than you need at any given time making it one of the most energy efficient ways of heating your home.
