Abstract
A water heater system includes a water tank and a flow-through heating assembly. The water tank contains heated water. The flow-through heating assembly may extend into the water tank and heats water as water is passed through an interior channel of the flow-through heating assembly. In one embodiment, the flow through heater assembly is a thermosiphonic heater having a hollow body and a heating element extending therein such that an annular recess is defined between an interior surface of the hollow body and the external surface of the heating element.
Claims21
A heater comprising:
- a fluid tank;
- a hollow body coupled to an interior of the fluid tank to define an interior volume between the hollow body and the fluid tank, the hollow body having an inlet and an outlet that is in fluid communication with the inlet, the inlet being arranged at a bottom end of the hollow body and the outlet spaced away from the inlet towards a top end of the hollow body;
- a heating element arranged within the hollow body, the heating element having a heating surface configured to heat fluid flowing through the hollow body;
- a cavity formed between the heating surface of the heating element and an interior surface of the hollow body;
- an outlet tube extending external to the hollow body and within the interior volume from the outlet of the hollow body and towards the inlet of the hollow body, wherein the outlet tube is configured to deposit the fluid heated by the heating element to a location within the fluid tank that is below a fluid level line, and wherein the outlet tube is in fluid communication with the inlet of the hollow body;
- and
- a warm water outlet line extending between the interior volume and an outlet of the tank.
