Geothermal expansion tanks are primarily intended to limit the pressure loss in a closed-loop geothermal system due to the expansion of the HDPE pipe in the ground loop.
Geo-Flo manufactures the industry’s only HDPE expansion tank that can be thermally fused into the loop creating a maintenance free, leak-proof solution for low system pressure in residential geothermal systems.
