200 Liter 53 Gallon Stainless Steel Solar Hot Tank Single Copper Coil Heat Exchanger vs RU98-EN

Stainless Steel Solar Water Tanks Active solar water heaters use an antifreeze as the working liquid in the system. This liquid carries the heat collector from the sun to a tank stored in a different place. To exchange heat to the water inside the tank, a heat exchanger is needed. Our solar water tanks come with a fitted copper heat exchanger, so the working liquid can simply pass through the coil, heating the water inside. Stainless Steel Tanks Are Better than Vitreous Enamel Tanks Our tanks are made of food grade stainless steel layered with a galvanized steel shell on the outside for increased strength against high pressures. Stainless steel is superior in solar water heating applications because it can handle the high temperatures made by solar water heaters, has excellent corrosion resistance and can handle the constant high pressure as result of constant heating during the day. Vitreous enamel tanks are made of carbon steel and use a glass lining to protect the steel from corrosion. Unfortunately, these cheaper style tanks can not handle the constant pressure in solar water heater systems. When the water temperature rises to 70C or greater, which is common for a solar water heater system, there's high risk of cracking of the glass lining caused by extreme expansion and sticking to the carbon steel. Once cracks have made, the carbon steel may quickly corrode caused by contact to the water, which frequently results in premature failure. Copper Heat Exchange Coils Every tank comes with a copper coil in the bottom of the tank for heating by the solar loop. The coil extends from where the ports enter and down to the bottom of the tank so that the complete tank of water may be heated completely by the solar loop. Dual coil tanks come with a 2nd coil installed on the top. The top coil may be used for other heat applications.

GMO Enamel Indirect 40 Gallons Tank - 1 Coil

GMO worked on the enamel covering heat exchanger for indirect tank. The heat exchanger is enamel covering, which can protect the heat exchanger from corrosion. Its advantage is low cost, high efficiency, safe, no leakage, life, and meeting drinking water standard. How Indirect Water Heater System Work? Indirect water heater system means the water in the storage tank is heated by heat exchangers, instead of direct heat. The water in the indirect tank will not go through the gas boil, or solar panel directly. The heat transferring medium will be heated by the gas boiler, or solar panel, then the high temperature heat transferring medium will move the heat to the water in the indirect tank by heat exchangers. Indirect water heater system is a perfect selection for multi-energy system combining with gas, solar, electricity. It may be used for the instant hot water and room heating.
