Ground source heat pumps draw the heat from the Earth to heat your home.
Air source heat pumps are versatile systems that heat and cool your home efficiently.
Water source heat pumps extract heat from water and convert it into energy to heat your home.
A full range of air conditioning, boiler, radiator, underfloor heating and fan coil services available.
A heat pump is a device that is designed to use a refrigeration cycle to effectively transform low-temperature energy into higher-temperature energy. Ground source heating system heat pumps are up to four times more energy efficient than the most efficient oil and gas boilers. These devices move heat that already exists rather than producing emissions that contribute to global warming through producing emissions caused by burning a fuel.
Ground source heating systems are electrically powered and work by tapping the natural heat that is stored in the earth to heat your home. In addition to heating your home, a heat pump can also cool your home during the summer months, as well as heating your swimming pool and your domestic hot water.
The system extracts this heat from the earth using, for example, a ground loop. This is a continuous closed loop made of a special kind of piping that is buried in the ground, in your garden. As water circulates through these underground pipes, it absorbs the heat from the earth surrounding the pipe. A heat pump inside your home is connected to this ground loop; and as the water reaches your home, the ground source pump transfers the heat from the water into your heating circuit for renewable heat.
There are two options for installing the ground loops: Installing them in bore holes of up to 90m deep; or burying them in trenches measuring up to 2m deep. The method that will be used for your ground loop will depend on the amount of space available in your garden, but both methods are equally efficient.
You will be able to use radiators and under-floor heating to distribute heat throughout your home. While the best option for optimal efficiency and benefit for a heat pump would be under-floor heating, you could also use extra or oversized radiators.
There are a few points to check before you begin looking at ground source heat pumps in detail, in order to make sure your house is suitable for this option of heating. For example, do you have enough space just outside your home for a bore or trench to be dug? You will also need to make sure that the ground is suitable for digging.
An air source heat pump is a device that is able to absorb heat from the outside air, and then deliver this heat within the interior of buildings. There are actually a couple of types of air source heating system technology available today. First of all, there are air to air systems which are able to provide warm air, that which is circulated to heat an entire building, and air to water systems which also accomplish a similar task, heating water which can provide both heating and hot water for buildings via radiators, or and underfloor system in the building itself.
If you have an electrically heated home in the UK, if these units are installed, based upon figures that were obtained from the Energy Saving Trust, these air source heat pumps could actually help save £870 every single year on heating bills as well as prevent the release of 6 tonnes of carbon dioxide throughout the year. This savings will of course vary depending upon what type of fuel is actually being replaced.
An air source heat pump is a device that has three primary parts:
There is the evaporator coil which is able to absorb heat from the outside air. The compressor pumps a type of refrigerant through the heat pump, then compresses the gaseous refrigerant to the proper temperature for heat distribution.
The heat exchanger will then transfer the heat made available through the refrigerant to either air or water.
The air-to-water system will then make it possible for the heat to be used to heat water which can preheat water within a storage tank, or it can circulate through the underfloor of a building or can simply be redirected to radiators.
Heat pumps will produce very hot water which will actually be at a lower temperature (typically 35-45o C) than what is typical of standard boiler systems, which then will make the underfloor heating very effective. Additionally, the air-to-air system can be used to produce warm air which is circulated by fans that are part of the system that can heat an entire building.
Here are a few conditions to consider before using an air source heat pump in this capacity:
First of all, you will need on an external wall for an installer to place the evaporator coil. You also need to think about the fuel but is being replaced.
