FLUID HEATING SYSTEM AND INSTANT FLUID HEATING DEVICE
First Claim
1. A fluid heating device comprising:
- an inlet port;
an outlet port;
a drain port;
at least one heat source connected with the inlet port and having a first heat source outlet;
a valve manifold connected to the at least one heat source, the drain port, and the outlet port;
a temperature sensor connected to the valve manifold for detecting a temperature of fluid downstream of the at least one heat source; and
a controller that regulates a power supply to the at least one heat source, whereinthe controller actuates the valve manifold to discharge fluid in the heating device via the drain port when the temperature sensor indicates the temperature of fluid downstream of the at least one heat source is below a predetermined temperature, andthe controller actuates the valve manifold to discharge fluid in the heating device via the outlet port when the temperature of fluid downstream of the at least one heat source is at or above the predetermined temperature.

Abstract
A fluid heating system may be installed for residential and commercial use, and may deliver fluid at consistent high temperatures for cooking, sterilizing tools or utensils, hot beverages and the like, without a limit on the number of consecutive discharges of fluid. The fluid heating system is installed with a tankless fluid heating that includes an inlet port, an outlet port, a drain port, at least one heat source connected with the inlet port, and a valve manifold connected to the at least one heat source, the drain port, and the outlet port. A temperature sensor is downstream of the at least one heat source and connected to the valve manifold. The valve manifold is operated so that an entire volume of a fluid discharge from the fluid heating system is delivered at a user-specified temperature (including near boiling fluid) on demand, for every demand occurring over a short period of time.
