<p>The heating system comprises a boiler, and a heater element accommodated in floor or ceiling. The circuit (2, 3) for the medium flowing through the boiler (1) is separate from that (7, 8) incorporating the heater element (9), heating being tranferred between the two by means of a heat exchanger (4). There can be a stop valve between boiler and heat exchanger, controlled by two thermostats, one measuring the medium temperature flowing through the heat exchanger and the other that of the room to be heated.</p> |
