Ground Source Heat Pumps
You may not realise, but your garden soil is a good source of heat energy throughout the year as it maintains a constant temperature of around 11-12ºC.
By using ground source heat pumps, you can extract some of this energy and transfer it to your home or business.
These systems are eco-friendly and extremely efficient, generating heat up to five times the electrical energy used to power the pump.
How Ground Source Heat Pumps work
An outdoor network of pipes that are filled with water and antifreeze are laid out and buried within the ground. At one end of this system is a pump which drives the solution around the pipes.
As this liquid is passed through the pipe, its temperature is raised by heat within the soil. Pressure is built up as the liquid is continually pumped through the piping, which causes the temperature to increase further, so that by the time it completes a circuit, the solution within the pipes has gained sufficient heat that it can be transferred to an internal heating system.
Benefits of Ground Source Heat Pumps
Ground source heat pumps are designed to provide all the necessary heating and hot water requirements for your home/business.
The main advantage of this type of system is that it is ecologically sound and delivers a real cost-saving benefit.
It is ideal for people who are trying to lower their emissions and is perfect for homes and businesses in remote locations, that are not connected to mains gas pipelines and are dependent on fuel deliveries.
In addition to those benefits, these installations are relatively low maintenance.
It is estimated that heating accounts for around 35% of the UK's annual C02 emissions. Switching to ground source heat pumps will help to reduce your emissions and lower costs; the average electrically-heated home could see savings of around £840 and 6 tonnes of C02 per year.
Homes heated using lpg, oil or Calor gas could see far greater savings as well as being more convenient.
Traditional methods of heating typically use non-renewable energy such as gas and oil, or take their power from non-renewable electricity supplies. In most cases, these are extremely inefficient as well as being heavy polluters.
In comparison, heat pumps are a much more efficient technology, having a COP (coefficient performance) rating of at least three; this means for every unit of electricity used to power the heat pump, the user benefits from three units of heat energy.
In actual fact, depending on the type of pump and installation you have, this figure is quite conservative as many organisations report a COP of between 5-6 and beyond for this technology.
