★ Environment-friendly 50 mm thickness insulation ensure its very low heat loss and high hot water output.
★ The water heater meet the drinking water standard.
★ Top quality parts: Incoloy 840 heat element, Emerson 89T or 59T66T thermostat, Watts T/P Valve.
★ WaterMark, CE Certificate
Very Low Heat Loss Value
GMO use pressurized insulation for the water heater. The density is about 40 Kilogram/m³. So the water heater can be high efficiency, low heat loss and energy saving.
Blue Diamond Coating
GMO enamel coating is made from the American Ferro enamel powder. The enamel coating meet drinking water stand. Enamel solubility reach Y class. It can resist against 85℃ hot water.
Stronger Anode Rod
GMO stronger anode rod can perfectly protect the inner tank of the water heater against the corrosion, and ensure the even longer life of water heater.
Dip Tube For Hot Water
GMO design the dip tube for the hot outlet, in order to get the highest temperature hot water from the top of the electric water heater, increase the hot water outlet.
How Direct Solar Water Heater System Works
Direct solar water heater is combined with direct solar water tanks, working station, and solar collectors. The pump inside the working station force the water in the tank to circulate in the system. When the water go through the collectors, it will be heated by the collectors, and become hot, then return to the solar water tank. In this way, the water in the tank will gradually become hot. There will be a heat element in the middle of the tank. When the sunshine is not good, the heat element can work and heat the water.

Best Material and Parts
High Quality Enamel Tank, Begin From Every Piece Of Cylinder Steel Plate
GMO enamel cylinder use the special steel plate for vitreous enamel coating. This steel plate is developed by GMO and Baosteel. Its yield strength of steel plate reach 340 Mpa.
Acid Pickling? No !
We Only Use Physical Environment-friendly Clean Process.
Adopt high temperature high pressure spray degreasing process, clean the dirty and oxide on the steel surface. This process abandon the traditional acid phosphate chemical. It effectively increase adhesion of the enamel coating, and avoid the waste water and environmental pollution.
We Begin To Think How To Increase The Enamel Vitreous Coating Adhesion From The Pretreatment
We use small steel ball direct blasting. Sandblasting the steel plate surface to form a uniform distribution of a large number of irregularly shaped open pit type. It effectively control the rolling cracks of the pretreatment. After blasting, the steel plate surface roughness is maintained at about 80%, to greatest extent, the enamel can penetrate to steel layer, improve the enamel coating adhesion.
Flexible NC rolling
In the special enamel steel sheet rolling molding process, if the process strength control is not correct, it is easy to cause the steel sheet pulled over and deformation, and thus directly affect the welding quality. GMO use the Flexible NC Rolling Technology, it can avoid this problem, and ensure the cylinder can be nearly 99.99% round appearance.
Infrared Positioning Welding
Adopt infrared positioning welding guarantee the accuracy and efficiency, and effectively prevent the cylinder surface cracks, sharp corners and edges and other defects before enamel coating process.
GMO Enamel Confidential Formula
GMO water heater factory finally develop the enamel special formula for hot water storage tank through joint research with European, American experts. This kind enamel’s bulk density, particle size, and slurry adsorption has high standard, with high adhesion and corrosion resistance, reach drinking water standards.
360 Degree Smart Enamel Lining Equipment
860 Centidegree High Temperature Sintering
By strictly accurate speed settings, temperature settings, drying in time, to avoid sagging before sintering, avoid enamel coating chapped, loss, guarantee the physical and chemical properties of the enamel coating.
100% Cylinder Air Tightness Test
In order to ensure all the cylinder welding line is qualified, GMO will do the air tightness test for all the water heater cylinders. Input the rated air pressure into the cylinder, and maintain several minutes to check the leakage, in order to ensure that passing rate and high quality.
Pressurized Foaming Machine
GMO use pressurized foaming process for the insulation. GMO use eco-friendly polyurethane material with more than 95% closed cell and fire retardant material. Polyurethane Density is about 40 kg/m3. Closed cell PU will provide polyurethane that will not absorb water nor water vapor nor humidity.
