Appl. No.:

11/323436

Inventors:

Michael James Hubbard - Dallas TX, US
Mark Allen Ferguson - Keller TX, US
Frank Austin Myers - Mansfield TX, US
Paul James Bothner - Arlington TX, US

Assignee:

PVI Industries, LLC - Fort Worth TX

International Classification:

F22B 1/26

US Classification:

122 312, 122 183, 122 1301

Abstract:

A water heater is shown having a closed metal tank with an upwardly mounted combustion chamber and burner/blower assembly. Curved fire tubes convey the products of combustion from the chamber to an exterior mounted flue assembly. The closed tank is enclosed by a rotomolded jacket. A support stand with vertically arranged support legs supports the tank in a normally vertical position but also allows the tank to be pivoted to a horizontal position on the support stand for maintenance or repair operations.

Appl. No.:

9/189213

Inventors:

Michael J. Hubbard - Dallas TX

Assignee:

Teledyne Technologies Incorporated - Los Angeles CA

International Classification:

F24H 100
F24H 902

US Classification:

126307R

Abstract:

A heater includes a housing having an angled top, a fan having a discharge disposed parallel to the angled top of the housing, and a baffle for laminarizing airflow through the heater. The heater may also create airflow through a cover, across a housing, a heat sensitive component, and/or a raceway, and into a housing inlet. The heater may include a manifold having at least one coupling member that slidingly engages and disengages a burner. Methods for propelling combustion air through a heater, laminarizing combustion airflow in a heater, improving the efficiency of a heater, and converting a heater to make it compatible with a different fuel are also disclosed.

Michael J. Hubbard - Dallas TX, US

International Classification:

F22B 1/08
F24H 1/00

Abstract:

A system is shown for providing domestic hot water for potable use. The energy source is a steam powered heat exchanger. Water is heated in a heat engine package including the heat exchanger, a temperature operated pump and a condensate control valve. The heat package works in conjunction with a water storage package including a water storage tank and an electronic controller which controls the operation of the pump and condensate control valve. The electronic controller is operated so that the control of steam supplied to the system and flow of water through the heat exchanger ensures that steam is only present in the heat exchanger when there is a predetermined high flow rate of water.
