ABSTRACT:
An efficiency and safety and economy-improved water heating system with a water-containing casing around a coaxially central upright flue having a combustion chamber at the bottom which is open for the purpose and a closed upper end, and, connecting with the upper end of the upright flue, a plurality of downdraft flue elements passing helically downward through the water-containing casing to a power-exhaust element which positively draws combustion by-products up through the flue and down through the flue elements for heating water flowed through the casing; improved, readily removable perforate basket burner structure produces diverse, well ventilated combustion paths in the combustion chamber further enhancing efficiency and safety and ability to use the unit with gas or oil.
