Heat pumps are a very effective renewable energy solution for use in residential or commercial energy plans. Heat pumps have 2 differing types, air source or ground source; operating on the same principle of taking heat from the air or the ground and transforming this to run your heating or hot water systems in place of a conventional boiler.
Heat pumps are virtually maintenance free and typically have a life span of more than 20 years, which means a heat pump can often outlast two conventional boilers!
Heat pumps work on the same principle as your refrigerator, by transferring heat energy from one place to another. They can take heat energy from the outside air at temperatures as low as -20°C and supply that same energy they’ve absorbed at a higher usable temperature for your heating and hot water.
A heat pump supplies your home in the same way as a conventional gas or oil boiler, utilizing a mains pressure indirect cylinder for all your hot water, it can then use either radiators or under floor heating to maintain your property to your preferred temperature.
As heat pumps take solar heat from the outside air or the ground, they are highly efficient. Heat pumps require an electrical power supply to operate, but absorb on average 3.5 times more energy from the air than what you put in; an efficiency of 350%. By comparison the most efficient gas boilers available are at most 97% and oil boilers at 80%. The solar heat which they absorb is free and readily available.
As you will appreciate much like led lighting, heat pumps are becoming a “must have” as a key part of a renewable energy plan as they can offer significant financial and carbon reducing benefits.
An Air Source Heat Pump fits into your home in the same way as a conventional boiler except it is installed externally rather than taking up room in your kitchen or garage.
Heat pumps are can extract heat from air as low as -20ºC and will operate at the optimum efficiency level throughout the year. The technology it incorporates will automatically regulate the system so that it never uses more energy than it needs at any given point, making it one of the most energy efficient ways to heat a home and provide hot water.
Air Source Heat Pumps are a suitable for the majority of existing houses, as well as new build developments. It is advisable that the property has a good level of thermal insulation in order to achieve the highest levels of efficiency.
Ground Source pumps take heat from the ground and use it to provide a total heating solution throughout the year for both homes and commercial premises.
Just a meter below ground level the temperature is typically between 7 and 12°C.By installing a ground loop, as a set of pipes, at this depth, this heat can be extracted and used for all types of heating and hot water provision.
Ground source heat pumps offer the following benefits:-
