Abstract

In a hot water heating installation comprising a heat generator (1), circulating pump (4) and radiators (6, 6a, 6b) regulated by thermostatic valves (7, 7a, 7b), wherein the supply temperature is variable, a regulator (11) is influenced by the supply and return temperatures and so changes the supply temperature that the difference between the supply and return temperatures is kept at a predetermined desired value. The desired value need not be constant but may be predetermined as a function of the return temperature. An electronic regulator or a differential thermostat may be employed as the regulator (11). In this way, the efficiency of the heating installation can be improved in dependence on the load. <IMAGE>
