NOVELTY - A heating medium has a heating composition containing water, sulfuric acid (in g) (0.25-2.64), magnesium (1.26-1.27), potassium (0.3554-0.386), tetraethylene glycol diethyl ether (9.0-9.9), ethylene glycol (6.0-6.6), dipropylene glycol methyl ether (6.0-6.6), tripropylene glycol monomethyl ether (6.0-6.6), methoxytriglycol acetic acid (6.0-6.6), diethylene glycol (6.0-6.6), methoxytriglycol (6.0-6.6), diethylene glycol diacetate (6.0-6.6), tetraethylene glycol dimethylether (9.0-9.9), triethyleneglycol (9.0-9.9), triethanolamine (9.0-9.9) and tetraethylene glycol (9.0-9.9).    USE - Heating medium for multipurpose electric sauna drier that is utilized for house keeping.    ADVANTAGE - The heating medium removes the odor from air and prevents the corrosion of instrument. The breeding of the mold or other bacteria is prevented. The heating medium is inexpensive and safe, and has excellent energy-saving property and thermal efficiency.    DETAILED DESCRIPTION - A heating medium has a fixing member for front wall frame comprising a sandwich panel, door, handle (02-1), sight glass made of heat-resistant plastic material (02-2), humidifier (03) and waterproofing antiseptic material inside and outside the medium. The medium comprises effective microorganism dilatants stored in a storage tank (03-2), light power generation electric system (04), solar cell module array (04-1), storage battery (04-3), current regulator (04-4) e.g. DC-AC power converter and power switch (05-1) and system for sensing temperature (05-2). An air conditioning system (11) rapidly flows the air for drying and ejecting the moisture.
