Regulating device for a central heating plant containing a hot water supply, comprising a boiler for heating a heating medium, a pipe for feeding the heating medium to space heating elements, a distribution device which is accommodated in the feed pipe and has a connection to a flow-through heat exchanger which is also connected to a return pipe from the space heating elements to the boiler. A pipe for tap water being provided in the flow-through heat exchanger and said flow-through heat exchanger being provided with a thermostat which operates the distribution device in order to change from circulation through the space heating elements to circulation through the flow-through heat exchanger and vice versa. The thermostat being adjustable to permit setting of the minimum temperature in the flow-through heat exchanger at which the distribution device switches over from space heating to circulation through the flow-through heat exchanger.

In a regulating device for a central heating plant having a hot water supply, a boiler for heating a heating medium, at least one space heating element, a feed pipe connected from said boiler to said space heating element and a return pipe from said space heating element to said boiler to define a circulation path, a flow-through heat exchanger connected between said feed pipe and said return pipe, a distribution device in said feed pipe at the connection to said heat exchanger, a pipe for hot tap water passing through said heat exchanger, a thermostat connected to operate said distributor device and responsive to the temperature of the hot water passing through said heat exchanger such that at a first predetermined temperature the distribution device is operated to circulate the heating medium through said heat exchanger and at a second predetermined temperature the distribution device is operated to circulate the heating medium to said space heating element, said thermostat being selectively adjustable to one of a plurality of first predetermined temperatures whereby a lower first predetermined temperature increases the time required to heat the hot water to a desired temperature but reduces the energy necessary to supply the hot water at the desired temperature during a long period when hot water is not used, the first predetermined temperature being lower than the desired temperature.
