Compact steam-fed heat exchange system
First Claim
1. A compact tank-less self-contained modular hot water supply system, comprising:
- a first module comprised of a heat exchanger having a steam path with an inlet connected to a second module and an outlet connected to a third module, a water path with an inlet connected to a fourth module and an outlet connected to a fifth module, the steam path adjacent the water path for transferring heat thereto;
the second module configured for receiving a steam supply and controlling a flow of steam therethrough, the third module configured for receiving a flow from the outlet of the steam path;
the fourth module comprised of a cold water supply to the water path inlet;
the fifth module configured for receiving a hot water supply from the water path outlet; and
a sixth module having an inlet, a configuration for monitoring and modulating the pressure and temperature of the hot water supply, and an outlet for delivery of temperature controlled hot water.

Abstract
A compact tank-less self-contained modular hot water supply system is provided for utilizing steam by-products from boiler systems for on-demand supply of temperature-controlled hot water in high volumes suitable for commercial applications. The modular system includes a brazed-plate type heat exchanger with a steam side providing a heating source, and a separate water side for production and delivery of hot water. Precise temperature control is provided by a module that adjusts the temperature of the hot water supply in communication with a module that regulates the flow of steam into the heat exchanger. The modular hot water supply system is contained within a housing which is mountable on a vertical or a horizontal surface.
