Filed:

Mar 5, 2007

Appl. No.:

11/715084

Inventors:

Scott Gilman Humphrey - Powder Springs GA, US
Timothy J. Shellenberger - Tyrone GA, US
James Stuart York - Sharpsburg GA, US

Assignee:

Rinnai America Corporation, a corporation of Georgia - Peachtree City GA

International Classification:

F24H 9/00
F24H 9/20

US Classification:

122 133, 122 141, 122 142

Abstract:

A water heating system including a water container having a cold water inlet that connects to a water supply, a hot water outlet, a water heater outlet and a water heater inlet; an instantaneous water heater mounted to the water container and having a tank supply inlet connected to the water heater outlet, a tank supply outlet connected to the water heater inlet, a burner, and a heat exchanger located adjacent the burner between the tank supply inlet and the tank supply outlet; a pump connected between the water container and the instantaneous water heater that moves water between the water container and the instantaneous water heater; and a controller that operates the pump and the burner.

Appl. No.:

16/990603

Inventors:

- Peachtree City GA, US
Matthew Ryan Dettmering - Newnan GA, US
Scott Gilman Humphrey - Newnan GA, US

International Classification:

F24H 9/20

F24D 17/00

Abstract:

A hot water supply system decouples an intelligent hot water storage system from a water heating engine system. The water heating engine system includes a plurality of instantaneous water heaters that provide for redundant operation for improved reliability. The intelligent hot water storage system includes a storage tank that encloses a volume for storage of water. The intelligent hot water storage system includes a recirculation loop driven by an integrated pump and operated by an integrated controller. By positioning the tank recirculation outlet and inlet farther apart from each other, additional usable volume of hot water is provided by the intelligent hot water storage system. Isolation valves positioned on the input and output of a recirculation pump in the recirculation loop facilitate repair or replacement of the recirculation pump. The hot water system provides for increased capacity while providing redundant heating engines in a smaller floor space than conventional systems.
