The Best Solar Water Heater
Which brand is the best solar water heater?
Reply: GMO Solar Water Heater.
There are a very large number of solar water heater factories around the world. The best solar water heater must be a hot water pressure-bearing system. The system can provide comfortable and pressurized hot water to the home at all times.
The principle of pressurized water heaters is the principle of displacement.
When you turn on the hot water tap, as much hot water exits the water heater as cold water enters the water heater. Pressurized water heaters require even higher quality of the system.
What are the components of a solar water heater?
The solar water heater consists of solar hot water tank, solar collector, fittings, and system brackets. The quality of each component has a significant impact on the quality and efficiency of the system.

What is the Best Solar Hot Water Storage Tank?
Reply: GMO Enamel Coating Solar Water Tank.
On the market, solar water tanks are produced in a wide variety of materials, such as stainless steel 304, stainless steel 316, stainless steel 316L, Duplex, carbon steel with enamel coating.
Obviously, the stainless steel solar tank’s advantage is very light quality. Plumbers like stainless steel hot water tank very much. It is very easy to move it.
While the stainless steel tank can’t avoid the the problem of intergranular corrosion. Even the material is Duplex or stainless steel 444 with the advanced welding technology, the intergranular corrosion is still unavoidable.
Intergranular corrosion is a kind of localized corrosion. Along the metal grain boundary between the internal expansion of corrosion. Mainly due to the difference in chemical composition between the surface and internal grains and the presence of grain boundary impurities or internal stress. Intergranular corrosion destroys the bond between the grains, greatly reducing the mechanical strength of the metal. And corrosion occurs after the surface of the metal and alloy still maintain a certain metal luster, can not see signs of destruction, but the intergranular bonding significantly weakened, mechanical properties deteriorated, can not withstand the knock, so it is a very dangerous corrosion.
In the harsh water, and aggressive water quality area, the stainless steel hot water tank is easy to leak. Even the solar hot water tank is made from the Duplex stainless steel or 444 stainless steel, solar water tanks may also leak in 2 to 3 months in the bad water quality area in the bad water quality area. If the water supply is from desalinated water, rainwater, please make sure that the water quality meets the water supply requirements of the water heater.
GMO Solar Water Heater use enamel coating solar hot water tank. Inside the enamel furnace at 850 degrees Celsius, the enamel melts and combines with the carbon steel as one. The enamel layer has excellent corrosion resistance, and the enamel layer can isolate the water and carbon steel to prevent intergranular corrosion from occurring, ensuring that the enamel tank has a long service life, generally no less than a 5-year warranty.
When we choose the solar water tank material, if we are sure that the water quality of the water supply is very good, we can choose stainless steel solar water tank. If we are not sure about the water quality, or if the water quality is very poor, then we should go for the enamel solar water tank. Or we just choose enamel solar water tank, once and for all.
What is the Best Solar Collectors?
Reply: GMO Solar Collectors.
GMO selects 5% silver contained copper welding rod which has good fluidity, and uses vertical welding to make sure the welding material penetrate deeply into the copper tube and ensure the reliable sealing inside and outside of the tube. Also, the silver-contained welding rod ensures better flexibility avoiding any breaks or cracks caused by expansion and contraction.
Besides, all welded copper pipes must be strictly inspected before using. 15 bar air pressure, lasting for 1 minute.
GMO use 1.5~2 times thickness copper pipe than the common copper pipe thickness, in order to guarantee the product quality.
The solar collector is SolarKeyMark Approved, SRCC Approved.
And the collectors provide 10 years warranty.
What is the best solar water heater mounting frame, bracket?
Reply: GMO solar water heater Hurricane resistant, Aluminum Alloy Mounting Frame,
The best material for the system mounting frame, or bracket is Aluminum Alloy. It has the advantage of light weight and corrosion resistance. If we install the solar hot water system on an island, or in a seaside town, the Aluminum Alloy bracket is necessary, and it also should be Hurricane resistant. Because the environment is very susceptible to corrosion, Hurricanes happen all the time.
GMO can customize the mounting frame according to your installation site.
