<p>The present invention relates to a water bucket boiler. An insulating material of Teflon resin and silicon resin with good heat-resisting and electrical insulating properties is doubly and strongly covered on a heat generation wire of a coil. A predetermined length of a stable heating wire wherein there is completely no short circuit in the water is covered with roll of paper to be an underwater heater. A water bucket made of common synthetic resins becomes a body of a boiler. The underwater heater is embedded in the bottom of the boiler body for a water temperature to be automatically controlled by a temperature controller. Thus, in a farming area or a common household, without special facilities, a water bucket hot-water boiler is easily transferred to a desired place to usefully use hot water.</p> |
