The exchanger panels (110) of the heat receiver (10) of the heating system are arranged in the side surfaces of a body stump in an air duct (120) which is controllable with a coaxial fan (160). The throughflow system, which is formed by the exchanger panels (110) and works down to at least -15 DEG C, is arranged both for direct heat transport to the heat pump (15) as required and for indirect heat transport to the long-term heat accumulator (33) as required, it being possible to make the heat for the consumers available as required from the long-term accumulator (33) or from the heat receiver (10). The heating system is especially efficient and economically favourable by virtue of the controllable capacity constancy of its heat receiver and by virtue of the stockpiling supply of the consumers. <IMAGE>
