Ground Source Heating Systems

How does a ground source heat pump work?
A ground heat source pump uses a low pressure refrigeration gas to absorb heat from the ground, then compresses the gas to release the heat into water. The gas again goes round the system under low pressure and aborbs heat from the ground, then compresses the gas to release the heat into water. This process is ongoing whilst the heat unit is switched on.

Ground source heat pumps run at a low temperature so it is ideal for under floor heating systems. The downside to ground source heat pumps is that you will have to boost your hot water more than you would with the air source heat pump. Also if you have an already established garden then it will be quite an upheaval to install.

There are three types of ground source heat pumps: Boreholes, Cassettes and Slinky ground loop. To get around 2kw of heat a trench 1m wide and 1m deep and 30m long. With ground source heat pumps it is reliant on a warm summer to rejenerate the heat in the ground. Borehole systems are deep enough to overcome this problem.

Gas Escape

Turn off the gas emergency control valve  at the meter.

Eliminate all sources of ignition i.e. smoking, blowlamps etc.

Do not turn on electrical lights or switches.

Open all doors and windows to ventilate the area.

Contact the gas supplier if the smell of gas persists, or if the escape is suspected to be upstream of the emergency control valve or the smell of gas is outside or from another property.
