distribution module for installation of floor heating and radiator heating with

摘要

The boiler (1) flow pipe (6) feeds an horizontal distribution cylinder (17), in the module (M), from which (20) a radiator (e.g. upper floor) circuit (5,3) is supplied; this returns to the boiler pump (8) via isolating valves (36,37), between which a by-pass (33) to the other end of the cylinder is connected, through a differential pressure valve (35). Opt. an indirect-type water-heating cylinder operates in parallel with this circuit.Underfloor coils (2), e.g. in the ground floor, are connected (23,24) to separated intermediate points on the cylinder. This circuit contains a circulating pump (26) with a security control sensor (28), and a three-way mixer valve (24), controlling a by-pass connection (30) and operated by a regulator (39) having input from temperature sensors outside the building (38) and on the flow line (27).
