 CO2 neutral The geothermal heat tub GECO2® from BRUGG Pipesystems makes it possible to extract heat from the ground using CO2 as the transport medium and to feed it into your heating system. GECO2® consists of an helically corrugated tube fed down into the borehole and a pressure vessel with an integrated heat exchanger at the surface. No pump needed A major advantage compared with conventional systems (such as a brine system) is that using CO2 eliminates the need for a pump and thus enables heat to be drawn from the ground without using electricity. Whatever the weather Irrespective of the weather or the time of year the temperature a few metres below the surface is a constant 13 degrees centigrade. This heat stored in the ground is collected by the GECO2® tube and transported to the surface where it is feed into the heat pump and concentrated into usable heat. The use of CO2 is completely free of environmental risks in water protection areas too.   The saucepan principleThe CO2 in our geothermal tube rises out of the depths as a gas by itself, like steam in a saucepan. At the top it enters the heat exchanger and condenses there, transferring its heat to the heat pump. Helical corrugation Thanks to the helical corrugation of the BRUGG pipe, the CO2 condensate can run back unobstructed into the geothermal tube without colliding with the constant upward flow of gaseous CO2 taking heat to the surface. Heat which costs nothing When this free heat has arrived at the surface, it is fed by the heat exchanger into the heat pump installed in the house and compressed there till it reaches the required temperature for use.

 Design We work out the best system solution for you depending on your heating needs and the type of soil. Drilling Drilling the borehole for the sensor tube must be done by a specialist contractor who is correctly certified. Sinking the sensor probe The sensor tube is sunk into the ground with the help of additional weights; after this the void is filled in with ThermoCem®. Installing the vessel The geothermal pipe is joined to the vessel by means of a connector fitting. The connection of the thermal evaporator to heat pump installation is then carried out by a specialized company for air-conditioning and refrigeration systems.  Environmentally friendly The danger of contaminating ground water is eliminated due to the use of pressurised CO2 as a heat fluid; this is the reason why GECO2® can also be used in water protection areas. Energy-efficient A helically corrugated stainless steel pipe with optimal heat transfer properties. Since no circulation pump is needed, no power is required to drive a brine pump, which means a higher coefficient of performance (COP) for the heat pump. Economical Sustainable (CO2 Neutral) energy consumption at zero cost. GECO2® has up to 35 % better performance compared with a brine probe system. Thanks to the stainless steel pipe (no corrosion). GECO2® has a longer service life than copper probes. Independent of weather conditions Geothermal resources are completely unaffected by temperature fluctuations due to weather conditions or seasonal changes and thus available at all times.
