Apparatus for heating at least two liquid containing vessels, mounted separately in heat exchange relationship with a closed container containing a heating medium communicating with a pressure or temperature sensitive adjustable control unit and heated directly by a single heat source comprises, as shown, a directly heated evacuated container 1 partly filled with a vaporizable liquid 2, preferably water, and containing within an evacuated space 3 a hot water supply boiler 4 having cold water inlet and hot water outlet pipes 5, 6, respectively. The container 1 is mounted within a central heating boiler 7 enclosed by insulation 8 and connected to radiators 11 and to a circulating pump 10 controlled by a room thermostat 13. The evacuated space 3 is connected to a chamber 15 of a control unit closed on one side by a pressuresensitive diaphragm 16 attached to a valve member 18 which is thereby moved to cut off the gas supply to the burner 17 when the pressure in space 3 reaches a given value, which can be adjusted by a handle 19. A pilot burner 20 adjacent the burner 17 heats a thermocouple element 21, the current from which operates a solenoid 22 to maintain open a gas shut-off valve 23 only when the pilot light is alight, the gas supply to the pilot burner is controlled by handle 24. In another embodiment a third liquid is heated in a spiral tube placed around vessel 4 within the space 3 and in a further embodiment two liquids are heated in similar vessels placed within space 3 and combustion gases from the burner are passed through horizontal pipes in the water space of the closed container.",
