<p>In a heating installation comprising a boiler and heat pump of which the liquefier is disposed in the return line of the hot water circuit, a multi-stage compressor of the heat pump and the boiler are subjected to a temperature regulating device. The regulator (28) is subjected only to an outside temperature sensor (22) and a return temperature sensor (21) disposed directly behind the liquefier in the return line. The regulator contains an integrator (30) and, between the outside temperature sensor and the regulator, there is a desired temperature converter (31) as well as a limiter (32) therebehind which limits the desired temperature signal to the upper limit (55.degree.C) of the compressor (20) of the heat pump. The output signal (y) of the regulator (28) is fed with different response threshold values to the threshold value operating switches (33-36) associated with the compressor stages (I, II, III) and the boiler (11), the boiler operating switch (363 having the highest response threshold value. The supply water can be fed to the return line (15) only by way of the radiator or radiators (13).</p> |
