Disclosed is heat medium oil for the use of indirect heating equipment including various heating appliances, which is poured into a predetermined closed vessel and heated by the electric heater, and more particularly, to heat medium oil that is evaporated at a relatively low temperature, without the danger of explosion, achieves rapid heat transfer, and is made at a low cost. The heat medium oil is made by mixing 75 to 77% by weight of distilled water, 23 to 24% by weight of alcohol, and 0.5 to 1% by weight of sodium chloride, thereby maximizing heat efficiency even without the danger of explosion. |
