Method for heating by solar energy, comprises solar panel feeding primary circuit which has separate disconnectable heat exchangers for secondary circuits to supply hot water and heating water
A solar panel (3) heats a primary fluid (1) which is circulated by a variable flow pump (19) around a primary circuit (2). The primary circuit has a first heat exchanger (4) for hot water and a second heat exchanger (5) for heating water connected in series but disconnectable by valves (28,29). Each heat exchanger is separately controlled according to need and coordinated with a boiler (32) Independent claims are made for a heating installation which uses the method.
