A method and an apparatus for heating fluid with a gas heater and distilling fluid with the pilot light of the gas heater are disclosed. The apparatus for heating fluid and distilling fluid includes a main tank for containing fluid to be heated, a heater, adapted to have a pilot light, for heating the fluid in said main tank and an evaporator tank for vaporizing fluid received therein with heat from the pilot light. The method of heating fluid and distilling fluid includes heating a first volume of fluid with a heater having a pilot light and heating a second volume of fluid with the pilot light. A second apparatus for heating fluid and distilling fluid includes a main tank for containing fluid to be heated, a condensing tank adapted to pass fluid to said main tank, an evaporator tank for vaporizing fluid received therein, a condensing coil, disposed in said condensing tank, for exchanging heat between fluid vaporized by said evaporator tank and fluid in said condensing tank, a distillate tank adapted to receive condensed fluid from said condensing coil and an electric filament for heating fluid in said evaporator tank when a level in said distillate tank equals or exceeds a predetermined level.
