NOVELTY - Electric heater heat transfer medium comprises methanol, potassium chloride, ethylene glycol, calcium chloride, magnesium chloride, modified graphene, 1-3 C organic acid salt, auxiliary agent, corrosion inhibitor, and distilled water. USE - The electric heater heat transfer medium is useful for civilians in domestic heating. ADVANTAGE - The medium: has rapid transfer and absorbs heat, small electric power, high thermal efficiency, and remarkable energy-saving effect; and each group of electric heaters (heat transfer body length 0.9 m, height 0.3 m, thickness 0.08 m) only needs 400 w of power. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing electric heater heat transfer medium comprising (1) thermally insulating distilled water for 30-40 minutes, under conditions of pressure of 0.10-0.202 MPa and temperature of 100-105 degrees C, (2) adding 1-3 C organic acid salt in distilled water under condition of normal pressure and temperature of 60 degrees C, and stirring for 20-30 minutes, (3) adding methanol, potassium chloride, ethylene glycol, calcium chloride, and magnesium chloride, and stirring for 10-20 minutes, (4) adding modified graphene, stirring for 50-60 minutes, applying ultrasound, and ultrasonically treating for 30-40 minutes, and (5) adding auxiliary agent and corrosion inhibitor, and stirring process for 5-10 minutes, and cooling to obtain heat transfer medium.
