    Abstract: A vent apparatus is used to install a tankless water heater or similar equipment inside an attic without going onto the roof. The vent apparatus may include a main housing and an umbrella assembly movably disposed therein. The main housing (e.g., PVC pipe) is installed through the roof. The umbrella assembly may have a central rod with a flexible umbrella cover on top. The umbrella assembly is pushed up through the main housing until the umbrella cover exits the top of the main housing to cover it and prevent rain from entering the main housing. The bottom of the main housing is then connected to the tankless water heater. Additional embodiments are disclosed for tankless water heaters and other equipment with an air intake port and a gas exhaust port.

    Abstract: A direct contact water heating system employs a vertical water tower having a sidewall with a combustion inlet opening spaced above the tower lower end. A generally horizontal combustion chamber has a sidewall in communication with the tower combustion inlet and an end wall spaced from the water tower. A burner has a combustion outlet in communication with an opening in the end wall, the combustion chamber end wall having an annular area surrounding the burner combustion outlet. Products of combustion flow from the burner, through the combustion chamber into the water tower through the combustion inlet opening. A shell has an inner end attached to the water tower sidewall. A sidewall portion of the shell surrounds the combustion chamber sidewall and an annular portion is spaced exteriorly of the annular area of the combustion chamber end wall. An interior surface of the outer shell and an exterior surface of the combustion chamber form a closed envelope having a water inlet and a water outlet. A flow system passes water through the closed envelope to cool the combustion chamber. In a preferred embodiment the combustion chamber end wall and the shell annular portion are both frustums to provide more rigid support of the burner.

    Abstract: A dual direct contact water heater is described and consists of a heater housing having two sections, each section having a water reservoir. One section provides hot water at a high temperature and provides a source of heat exchange to heat an external source of water for commercial use. A burner is provided in the first section to provide the heat source to a packing through which water percolates. The source of water for the first section is the outlet of a heat exchanger whereby water from the reservoir is recirculated in a closed circuit in the first section. Hot gases rising from the first section is directed to a second section which also includes a second packing and a reservoir and it also has a closed loop whereby a second source of hot water, at a lower temperature, is utilized in a closed loop and in heat exchange with a second external source to produce domestic hot water or without heat exchanger to produce hot water for various processes. The fumes at the exhaust port of the second section are cooled considerably whereby the total efficiency of the water heater is greatly increased.
