ABSTRACT:
A heat exchanger system includes a boiler and a double sleeve pipe which is disposed in the boiler and has coaxial inner and outer pipes. The inner pipe is connected to a heat pump, and carries a first fluid medium. The outer pipe is connected to a fluid circuit which includes a pump and a three-way valve. The three-way valve can selectively connect into the fluid circuit a further three-way valve and a heating system, and the further three-way valve can selectively connect a further boiler into the fluid circuit. The inner surface of the inner pipe is preferably ribbed, and there is preferably at least one longitudinally extending wall in the inner pipe which divides it into two or more separate channels.
