Appl. No.:

10/680970

Assignee:

Riverside Hydronics, LLC - Fort Worth TX

International Classification:

F22B 2306

US Classification:

1223673, 122249

Abstract:

A finned tube water heater has a pair of flow manifolds each having a water inlet and a water outlet and a series of connected openings. Circular flow tubes have connecting ends which fit within the connecting openings of the manifold so that the tubes are arranged in a stacked fashion to form a tube bundle. A burner communicates with the interior space within the stacked tube bundle for producing products of combustion for heating water flowing in the flow tubes. The flow tubes have external fins which are crushed to form upper and lower flat stacking surfaces for stacking the tubes to form the tube bundle. The fins are also crushed to form angled baffled surfaces about a external periphery of the tubes. The baffle surfaces serve to retain heat from the products of combustion of the burner which are released into the interior space within the stacked tube bundle.

US Classification:

1223673, 1223671, 165182

Abstract:

A high efficiency heat exchanger is shown which can be incorporated into a finned tube water heater. The heat exchanger has a pair of flow manifolds each having a water inlet and a water outlet and a series of connecting openings. Circular flow tubes have connecting ends which fit within the connecting openings of the manifold so that the tubes are arranged in a stacked fashion to form a tube bundle. When incorporated into a water heater, a burner communicates with the interior space within the stacked tube bundle for producing products of combustion for heating water flowing in the flow tubes. The flow tubes have external fins which are crushed to form upper and lower flat stacking surfaces for stacking the tubes to form the tube bundle. The fins are also crushed to form angled baffled surfaces about a external periphery of the tubes. The baffle surfaces serve to retain heat from the products of combustion of the burner which are released into the interior space within the stacked tube bundle.

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.

Inventors:

- Fort Worth TX, US
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.
