Our Pressurized with enamel double tank system : Inner tank is enameled and second tank as jacket for inner tank. The glycol will circulate from collector to jacket to heat inner tank hot water.
Remark: About double tank , it means there is two tanks design for different purpose .Inner tank is for hot water storage use. Outside the inner tank there is another tank , it is just like a jacket for inner tank ,we can call it jacket tank. It is for fluid circulation purpose. The fluid (glycol) will depends on nativity to exchange heat between jacket tank and flat plate collector.
Components:
1. Storage tank ,special struction . Inner tank is enameled . Send tank warps the inner tank as heat exchanger. It looks like a jacket to keep the inner tank warm. 1pcs
2.Flat plate solar collector ,size 2000X1000X80mm ,2pcs
3.Bracket for hold tank and flat plate solar collector ,1pcs
4. Optional ,fittings for plumbing use. Flexible pipe and fittings for connect pipe to tank and collector, 1 lot

1.Enamel coating is well know for long lifetime. Anti-rust better than chrom .
2. Enamel tank wall is smooth ,not easy to breed bacteria ,harmless to water quality.
3.With jacket tank design as the heat exchange, the circulation fluid is heat transfer oil such as glycol. It is no harm to system , especially can keep the flat plate solar collector longer lifetime. Not like the directly circulation with water, There will be scale for long time working and the scale will block the system and lower the heating effeciency.
4.Good water quality for shower.
5.Easy cleaning . The tank is design with flange plate which can remove for maintein and cleaning job.
6.Our enamel is well coated in well look blue and enough enamel thickness to sure 5years guarantee.
Our special design of tank :
There is additional design with electric heater, Differ from the common design, we adopt the electric heater in 1 1/4'' adjustable double protection type that is easy to remove , change and save the electrical job. The common one is flange type electric heater, the electrical job will be complicate and replace job will be not so easy.

Haining Vod Solar Energy Industry CO.Ltd. is one of solar water heater manufacture focus on solar products and solar solutions for more than 20years. As solar water heater manufacture, we do mainly produce a large different ranges of solar water heater: open loop solar water heater, close loop solar water heater, solar thermal collector ,heat pipe solar collector and customized solar water heater. As a developing and energy saving factory, we supply different energy saving products: air source heat pump, solar pump, solar light, solar pv on-grid and off grid system, solar refrigerator, solar AC and so on.
In order to produce a high-quality solar water heater, we do investigate on large amount on producing machine and skill workers. We adopts 8 location automatic punching machine, arc-argon welding machine, automatically lines for solar manifold ,up and down foaming platform for foaming and other lead technical machines. About 85% workers have more than 10years working experience in solar water heater manufacturing. The professional engineer team is built especially for large scale solar water heating system design and installations. The team offers different solar solutions according to customer's different project request or single products request.
As a responsible solar water heater manufacture, we have a strict quality control in materials and production, we pay the double attention on producing. Even a screw, we test and choose the best for our solar water heater. We are do improvement details according the customer feedback and producing process. To offer a quality solar water heater, 100% solar water heater tank are tested and a sample set are installed to check if all is fine before delivery. All solar water heater we produced; the lifetime is more than 10years.Free exchange on damage goods fall in our warranty period.
