Abstract (en)
The system is based on fitting a thermostatic bypass (1) at the point of use of the water, such as a faucet (6), between the hot water pipe (4) and the cold water pipe (5), connected to a heating boiler (8) of a water consumption installation, so that opening and closing the faucet (6) will turn on the boiler (8) and the circulation pump (9) fitted in the hot water pipe (4), making the water run through said hot water pipe (4), the bypass (1), the cold water pipe (5) and the return pipe to the boiler (8), heating the water until a preset temperature is reached, at which time the bypass (1) is closed and the hot water is available at the faucet (6) when it is opened in the hot water position. The circulation pump is governed by a relay (10) that is activated by a flow switch (11) fitted in the hot water pipe (4).
