Ground source heat exchangers   GSHEs collect ‘free’, or ground source heat from the ground. They also recycle surplus heat energy generated above ground level to provide air cooling.     Lankelma Green Energy installs ground source heat exchangers by vertically pushing them into the ground using hydraulic rigs; the process is repeated and the installations cross-connected to produce a closed-loop installation. A heat transfer liquid is then circulated through the GSHE ground array by a ground source heat pump.    The installation depths are dependent and variable upon the soil groundwater conditions and the heat yield required. In order to select the correct system, the thermal conductivity of the ground needs to be investigated.  Find out more >>  No flue or ventilation system required   Low maintenance   Compact, no fuel tank or boiler required   Low and zero carbon (LZCs) systems   Life expectancy 50+ years  Applications    Heat pumps raise the temperature of the transfer fluid (heated via GHSEs)  to around 40 degrees, making them ideal for underfloor heating systems and low temperature radiators. They can be used in conjunction with auxillary systems, such as conventional boilers, to produce higher temperatures. On a larger scale, ground source heat exchangers may be used in a wide range of applications, from heating football pitches and swimming pools to heating and providing air conditioning for factories and municipal developments.
