Heating
Pipes and fittings must be insulated at 50% of their nominal diameter at junctions, crossings and central manifolds in accordance with the Building Energy Act (GEG). For heating circuit groups, this means a fully enclosing minimum wall thickness and separation of the flow and return lines. The Tuxhorn tubra®-PGM/PGR pump groups from DN20 to DN32 meet this requirement.
