Heat pumps are used to reduce CO2 emissions. They also save on heating costs. Therefore, heat pumps are generally very beneficial. Nevertheless, there is the risk of leakage.Brine-water heat pump systems consist of a brine-water heat pump, together with the heating side units and a sole system. Sole system include PE pipes, either vertically (geothermal probes) or horizontally (ground collectors) incorporated into the soil. Sole systems are risky of leakage at joints or PE pipes (damage, aging) in generall. It should be noted that glycol to water hazard class 1 counts and must not get into the soil or groundwater. Geoprotektors can avoid this safetly that confirms a report from the University of Bochum.The functionFirst of all a pre-alarm will be caused due to a drop in pressure detected via the digital pressure sensor. Then the heat pump switches off (DIN 8901 and VDI 4640). For a pressure drop, there are two options:In case of insufficient filling and a reduction in volume due to the cooling of the brine or leakage. Turn off the heat pump, the operator should contact an expert. Detects the Geoprotektor leakage is rinsed with potable water. A bin holds the purged brine.The useThe Geoprotektor has multiple benefits:1. He prevented a greater loss to the sole soil.2. The expensive flushed sole is resealable reversible.3. Contamination of the soil with glycol is avoided.
