Abstract
A fluid heater (100) comprising a storage reservoir (1) for storing heating fluid, a burner (5) for heating the heating fluid and a first heat exchanger (11) located outside said storage reservoir (1). The heater (100) also comprises a first fluid circuit (200) connecting the storage reservoir (1) with the first heat exchanger (11) for carrying heating fluid from the storage reservoir (1), through the first heat exchanger (11) and back to the storage reservoir (1), and a second fluid circuit (300) connecting a first inlet (19) for mains fluid to a first outlet (27) for heated mains fluid via the first heat exchanger (11). The first heat exchanger (11) is adapted to exchange heat between said heating fluid and said mains fluid.
Claims68
A fluid heater comprising:
- a storage reservoir for storing heating fluid;
- a burner for heating the heating fluid;
- a first heat exchanger located outside said storage reservoir;
- a first fluid circuit connecting the storage reservoir with the first heat exchanger for carrying heating fluid from the storage reservoir, through the first heat exchanger and back to the storage reservoir;
- and
- a second fluid circuit connecting a first inlet for mains fluid to a first outlet for heated mains fluid via the first heat exchanger,
- wherein the first heat exchanger is adapted to exchange heat between said heating fluid and said mains fluid.
A fluid heater comprising:
- a storage reservoir for storing heating fluid;
- a burner for heating the heating fluid;
- a first heat exchanger;
- a first fluid circuit connecting the storage reservoir with the first heat exchanger for carrying heating fluid from the storage reservoir, through the first heat exchanger and back to the storage reservoir;
- and
- a second fluid circuit connecting an inlet for mains fluid to an outlet for heated mains fluid via the first heat exchanger, the second fluid circuit including a portion that passes through an exhaust path of burner heat expelled after heating of the heating fluid,
- wherein the first heat exchanger is adapted to exchange heat between said heating fluid and said mains fluid.
A method for heating fluid, said method comprising the steps of:
- providing a supply of heating fluid;
- heating the heating fluid;
- providing mains fluid;
- heating the mains fluid by exchanging heat between said heating fluid and said mains fluid;
- and
- further heating the mains fluid using residual heat from the step of heating the heating fluid.
