Benefits of technology

It is an object of the present invention to provide a water heater of the power assisted type which prevents portions of water within a tank from being overheated or vaporized.
It is another object of the present invention to provide a water heater which reduces the negative effects of temperature layering within a tank.

Problems solved by technology

Moreover, because the circulating pump only moves water from place to place in the tank, it need not be very powerful and does not contribute significantly to the amount of energy used by the water heater.

Embodiment Construction

Referring now to FIG. 1 wherein the structures and steps shown are for the purpose of illustrating preferred embodiments of the invention only and not for the purposes of limiting same, FIG. 1 shows a water heater A including a water tank 10 supported in an upright position upon a cylindrical base 12. A combustion chamber 14 is located at the bottom of tank 10 and defined in part by an upstanding steel cylindrical wall 16 having a steel exhaust gas exit tube 18 at its top. The water tank 10 is surrounded by a layer of insulation 20 and a protective jacket 22 in the conventional manner.

When water heater A is in use, with the burner inactivated, tank 10 normally contains stratified body of water 24 with the coldest water remaining in the bottom portion of the tank and the hottest water having risen to the top portion. The water to be heated is introduced into water tank 10 through inlet piping 26 leading through bottom steel plate 17 of tank 10 and feeding water to an inlet water diff...

Abstract

A water and / or space heater is provided in which water is circulated to prevent the localized overheating or vaporization thereof.

Description

The present invention relates generally to water heaters and more particularly to a water heater which reduces localized overheating of water during heating.BACKGROUND OF THE INVENTIONHighly fuel efficient gas burning water heaters are often provided with powered or forced draft combustion systems. Such combustion systems typically employ a blower for forcing the gas / air combustion mixture to the burner and into the combustion chamber of the heating appliance. High efficiency power assisted water heating appliances are disclosed in U.S. Pat. No. 4,766,683 to Cameron et al and in U.S. Pat. No. 5,085,579 to Moore, Jr. et al, which patents are assigned to the same assignee as that of the present application. The disclosures of U.S. Pat. Nos. 4,766,883 and 5,085,579 are incorporated herein by reference.Moore 5,085,579 discloses a water heating apparatus in which a combustible gas / air mixture is introduced into a blower which moves the mixture under pressure into a vertically extending t...
