Benefits of technology

[0022]The operation of the water heater is inherently safe. Should a failure of the pump occur, no water will be circulated through the heat exchanger. While the water in the heat exchanger will be heated by the steam, an integral heat trap will prevent its introduction into the storage tank. In the event of a failure of the electronic controller, neither the pump nor condensate control valve will receive power. In addition, the system can be provided with is an upper temperature safety that will prevent the water from being heated to unsafe levels as well as a high temperature limit as required by UL safety standards. The heat exchanger itself can conveniently be of the double w

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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a storage type water heater system with a storage tank that is indirectly heated by a steam heat source, the system being used to provide domestic hot water for potable uses.[0003]2. Description of the Prior Art[0004]Water heaters are used in a large variety of residential, commercial and industrial settings. For example, large storage tank systems are often found in hospitals and institutions, industrial plants, schools, universities, apartment complexes, and the like. The different types of water heaters which are used to supply hot water to these systems may use various sources of energy, such as gas, oil, electricity or steam. For example, in conventional gas / oil fired water heaters, hot gas flows through a series of vertically mounted tubes which are mounted in vertical fashion between top and bottom support plates within the water heater tank. Water flows into and out of ...
