Heating supply network

摘要

The network has a heating boiler (1) operated at a temp. of between 80 and 110 degrees C, monitored by a boiler thermostat (8), with the boiler circulation pump (2) simultaneously operating as the network pump, with load-dependent rev control via a central control device. A manually adjustable 3-way valve (3) controls the recirculation path to the boiler, with a sensor (4) for monitoring a constant return temp. of 45 degrees C, to allow the pumps revs to be adjusted, with individual thermostat valves (6) controlling the heat supplied to each radiator (5).
