Benefits of technology

This invention is about a system and method for venting a water heater. The system includes a ventilation system with a blower, draft hood, and thermal switch. The draft hood is attached to the blower outlet of the water heater and receives the exhaust gas. The thermal switch detects blockages in the draft hood and shuts down the water heater to prevent accidents. The technical effect of this invention is to improve the safety and efficiency of water heating systems by preventing blockages in the draft hood.

Problems solved by technology

This consumption of fuel generates exhaust gas, which must be vented from the water heater.

Embodiment Construction

[0012]Aspects of the present invention relate to the ventilation of powered, atmospherically-vented water heaters. As used herein, the term “powered” in relation to ventilation refers to water heaters having a powered device, such as one or more blowers or fans, positioned to propel exhaust gas away from the combustion chamber and out of the water heater. Further, as used herein, the term “atmospherically-vented” refers to water heaters that vent exhaust gas to the atmosphere via non-positive static pressure venting.

[0013]While the systems and methods disclosed herein are described with respect to conventional water heaters, it will be understood that the invention is not limited to devices for heating water (i.e. H2O). As used herein, the term “water heater” is intended to comprise any device adapted to generate and maintain a source of heated fluid.

[0014]Generally, the disclosed systems and methods utilize a draft hood positioned on top of the blower to improve the water heater's ...

Abstract

Systems and methods for venting a water heater are disclosed. The system includes a water heater, a blower, a draft hood, and a thermal switch. The blower has a blower inlet positioned to receive combustion gas from the water heater and a blower outlet positioned to exhaust combustion gas. The draft hood defines a passageway positioned to receive combustion gas from the blower outlet. The draft hood defines a relief opening to allow gas to enter into or exit from the passageway of the draft hood. The thermal switch detects a blockage in the passageway of the draft hood and deactivates the water heater when a blockage is indicated. A method for venting a water heater includes blowing exhaust gas outward through a blower outlet of the water heater, and receiving the exhaust gas blown through the outlet with a draft hood positioned on top of the blower outlet.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to water heaters, and more particularly, to systems and methods for venting water heaters.BACKGROUND OF THE INVENTION[0002]Conventionally, water heaters are employed (e.g., in one or more buildings) to generate and maintain a readily-usable source of hot water for use (e.g., by the building's occupants). To generate the heat for heating the water, water heaters include a source of fuel, such as oil or natural gas, which is burned in a combustion chamber. This consumption of fuel generates exhaust gas, which must be vented from the water heater. There exists a need for improved systems and methods for venting exhaust gas from water heaters.SUMMARY OF THE INVENTION[0003]Aspects of the present invention are directed to systems and methods for venting a water heater.[0004]In accordance with one aspect of the present invention, a vented water heating system is disclosed. The vented water heating system comprises a fuel-f...
