Abstract: A domestic pipe system for delivery of hot water includes hot water source (10) and a piping to a faucet (12). The piping comprises a splitter (14), two pipes (20, 22) and a controller (16), the controller having a housing, first and second inlets (24, 26), an outlet (28), and a thermally actuated valve. The first inlet is a permanently open inlet whereas the second inlet is opened depending on the temperature of water arriving at the controller. Stagnant water that cooled down only runs through the first pipe (20) until the temperature exceeds a preset threshold. Than the controller (16) opens the second inlet such that the stagnant cold water from the second pipe can be mixed gradually with the hot water from the first pipe. Thus, the user receives warm water earlier than if both pipes need to be emptied.

Abstract: Controlling under surface heating/cooling by supplying liquid to at least two supply loops in an under surface heating/cooling system, and controlling the flow of the liquid on and off such that during the duty cycle the flow is high and between the duty cycles the flow is off. Room temperature is controlled by controlling the percentage of the duty cycles, which percentage is determined on the basis of the heating demand of the rooms. Different loops are controlled such that at least in two different loops the duty cycles start at different moments.
