The pipe assembly that can be screwed directly into the heat pump consists of two specially bent pipes that are tailored to the high-efficiency air/water heat pump, with transition pieces for the heating water connection. When installed close to the outside wall, these pipe assemblies that lead out of the side of the heat pump (base frame, blow-out side, right below the fan, on the left for LA 6S-TU) enable an above-ground introduction into the building (thermal insulation required for frost protection). This eliminates the need for the underground pipe routing that is standard for introduction into basement rooms.
