<p>PROBLEM TO BE SOLVED: To provide a warm water apparatus which includes a container which is filled therein with a mixture of mineral that involves aragonite type calcium carbide as a chief ingredient and a sintered substance that involves tourmaline as a chief ingredient, wherein a calcium carbide coated film is difficult to be formed on a corrosion resistant metal such as stainless but a calcium carbide film is formed on a corrosive metal such as iron. SOLUTION: An electric warm water apparatus is adapted such that it includes a closed type container having a water supply outlet in an upper portion thereof and a water suction inlet in a bottom thereof, and a heater provided on the side of a bottom surface of the container, and further including an insertion container disposed on the upper side of the heater, which is filled with a mixture of mineral that involves calcium carbide as a chief ingredient and a substance that involves tourmaline as an ingredient.</p> |
