<p>The heating system utilises environmental heat by means of a roof absorber and a latent heat accumulator in the form of a ground heat absorber, together with a heat pump. The expansion section of the latter is connected to both absorbers and the compression section to one or more consumer units, in each case by a circuit in which heat transfer fluid flows under the action of a pump. The expansion section (22) of the heat pump (13) is connected by a first circuit (23) to the ground heat absorber (12), which in turn is connected by a second circuit (31), separate from the first one, to the roof absorber (11).</p> |
