Abstract
An exemplary embodiment includes a booster water heater for fluids, e.g., water, that has a reservoir for the fluids, at least one electrical heating element extending into the reservoir and a control system for applying an overload voltage to the heating element. In a more preferred embodiment, the booster water heater is used to preheat water in commercial dishwashing applications.
Claims21
A booster water heater, comprising:
- a container for water having an inlet and an outlet;
- an immersion electrical heating element extending into the container;
- and
- a controller, wherein the controller is configured to adjust the electrical heating element voltage from a first voltage pattern to a second voltage pattern when a predetermined condition is met, and wherein the mean voltage of the first voltage pattern is at least 1.5 times greater than the mean voltage of the second voltage pattern.
1 more element
A fluid heater, comprising:
- a container having an inlet and an outlet;
- an electrical heating element coupled to the container, wherein the heating element is rated to operate at an operational level;
- and
- a controller, wherein the controller is configured to adjust the electrical heating element voltage and/or current from an overload level to the operational level after a predetermined condition is met.
1 more element
A method to reduce response time in an electrical booster water heater, comprising:
- supplying an overload voltage to a heating element until a predetermined condition is reached;
- and
- reducing the overload voltage to an operational voltage.
