Geothermal Piles - a briefing note by Balfour Beatty Ground Engineering

26 December, 2020

Concrete piles are used in a ground storage system to house closed circuits made from plastic piping. The pipes are used to circulate a heat transfer fluid which transports the ground temperature to the central control system for the building services. In

While the average temperature to be found in the concrete foundations is in the region of 12°C, the heat pump produces temperatures of between 25°C and 40°C in the heat transfer fluid, which is suitable for low temperature heating systems in floors and ceilings. These systems can be used for both heating and cooling purposes. BBGE can use bored, CFA, precast concrete and steel piles as geothermal piles.
