Page 5: Product Description
Product description Product description Product description The heating circuit K35 is a preassembled fitting group for hydronic heating closed-loop systems. The heating circuit is designed such that it can be directly mounted onto a mounting plate with thread connections or onto a distribution manifold. The distance between the pipe axis and the wall must be at least 10 cm, as the connection C-3 is on the back side of the mixing valve. -
