Abstract:
1. Apparatus for heating fluid and distilling fluid comprising: a main tank for containing fluid to be heated by means of a main gas heater including a pilot light for heating said main tank; a condensing tank for passing fluid to said main tank; an evaporator tank for vaporizing fluid received therein and being heated by means of said pilot light; a condensing coil, disposed in said condensing tank, for exchanging heat between fluid vaporized by said evaporator tank and fluid in said condensing tank; and a distillate tank for receiving condensed fluid from said condensing coil; wherein said pilot light heats fluid in said evaporator tank when a level in said distillate tank equals or exceeds a predetermined level for thereby substantially continuously allowing fluid in said evaporator tank to be heated and vaporized for providing distilled fluid and further substantially continuously allowing fluid in said main tank to be heated by serving as a substantially constant source of energy for igniting gas for said main gas heater, said apparatus further comprising a first fluid flow regulator for regulating fluid flow to said evaporator tank according to an amount of fluid in a delaying float bowl tank, and a second fluid flow regulator for regulating fluid flow to said evaporator tank according to an amount of fluid in said distillate tank.
