R F Blount are accredited heat pump installers.
Heat Pumps extract heat from natural sources such as the ground, air or water. They are efficient forms of heating options because they consume less energy than they generate. Heat pumps are now becoming very popular in newly built properties as the insulations in newbuilds are of a high specification. Depending on what is most readily available to the homeowner either the ground, water or air will be accessed with a heat source pump. Regardless of the building all properties will be suitable to have a one of the heat source pump installed. The longevity of the heat pumps are excellent as the components have a long shelf life. One of the main benefits is that the energy is from natural sources so it is a completely renewable energy source.
Ground Source heat pumps
R F Blount can make your home more energy efficient by abstracting heat from the ground, using a ground source heat pump or vertical borehole. Using the ground source heat pump method normally coils of pipes are buried into trenches about two metres deep. A mixture of anti freeze and water circulated around in the coiled pipe and the fluid absorbs the heat from the ground. The fluid is then put through a compressor and heat exchanger where it is then pumped into the house where it heats the water circuits. The fluid is then pumped back out creating a continuous process.
If you have limited space in your garden then you may like to consider vertical bore hole or an air heat exchange pump.
Air Source Heat Pumps
An air exchange unit will absorb energy from the air around you. It works in a similar way to a fridge but in reverse. The fridge extracts heat and keeps its contents cool where an air exchange unit extracts heat from the air and is used for example to warm air convectors, heat radiators, underfloor heating or heat water in the home. You may have concerns that Britain isn’t warm enough to accomodate an air exchange unit but heat can be obtained with temperatures as low as 14 degrees Celsius making it very efficient and appropriate for our UK customers.
Vertical Bore Holes
Vertical hole bores are normally installed into area’s where horizontal coiled loops can not be fitted. The area must be able to facilitate a digging rig where a 20cm diameter hole is bored out of the ground. The holes are typically spaced 5 meters apart and the depth of the hole will depend on the ground composition.
An example drill for a 12KW heat pump will require 150 meters of hole bored from the ground to heat the unit:
12 Kilowatt heat pump
150 meters of hole bore
3 x 50 meter hole bore
