Instant heating thermosyphon solar water heater 2020

 Poeple may questioned us why this type with name  solar water heater 2020.

Is it the best sales products?

My recommend it for this year cause it is really a nice solar water heater for 2020.

It is thermosiphon which passive circulation between tube and solar water heater tank. 

But also can get pressure hot water from heat exchanger of the tank.

It is economic and pressurized offer.

That's the reason i strong suggest for solar water heater 2020.

Item number: VODC-H460S2-36V

Following is material and design which get high score for solar water heater 2020

•   Hot water supply ability: 300L  , large capacity can both supply for hot water ,but also can be used for heating .
•   Internal Tank: SUS304-2B food grade level stainless steel, thick in 0.5mm; diameter 360mm
•   External tank: shinning 201-BA stainless steel; thick in 0.31mm; diameter 460mm.Bright and nice looking.
•   Heating Insulation Layer: Germany-imported polyurethane integrated foam-forming with twice slaking treatment, preservation time as long as 70~80 hours.
•  Frame:aluminum alloy ,anti-rust for long lifetime.
•   Instant heating absorbing: copper coil, diameter 12mm,thickness 1mm.Length 40meter . Offer instant hot water from the coil.

What way is the solar water heater 2020 works?

 Instant heating thermosyphon solar water heater provides pressure via a high efficiency copper coil heat exchanger which installed in the main tank.  All-glass evacuated tubes absorb and transfer solar energy into heat energy, then heat  up cold water inside vacuum tubes. It depends on the different density between hot water and cold water; A cycle creats in the tube which hot water rising and cold water descending status. The passive natural circulation repeats cycle all the time, the water in the tank becomes hotter and hotter. This hot water will transfer the heating energy by instant heating copper coil to supply hot water directly from coil to consumptions.

Do solar water heater 2020 work in winter?

If there is sun ,there is hot water .So it is depends on sun , if it is cloudy or rainy day, the solar energy is less or none, but don't worry,we can have a electric heater as backup to heat the water.

Can you give me more details on your solar water heater 2020?

My pleasure to introduce our solar water heater details,we trust details lead to high quality and we focus a lot on it .

•  Main capacity: hot water storage 300L
• Instant heating is a copper coil, fast cold-water heating ability.A large enough heat exchanger area makes sure to provide enough hot water .
•   Vacuum Tube: Hail-resisting borosilicate 3.3 glass with high-tech selective coating ensures an efficient solar collecting, tri-target vacuum tube with its patent interference coating makes the efficiency not only improved by 12% but also with a high temperature resistance (380oC). Glass in 1.6mm ,weight 2kgs ,strong against the external impact.
•   Heat preservation: foaming by high density polyurethane, main chemical foaming material is imported from Germany.
•  External  material of tank in stainless steel 201-BA, bright treatment
•  Internal tank steel adopts thickness in 0.5mm with a long lifespan (15 years).
•  Tank cover with no more risk on depart off by rivet up with aluminum rivet to main tank.
•  The fitting welded by Arc-argon to prevent any leaking of tank
•  The flange screw with anti-rust material is applied for fixing main tank to frame. It enlarges the contact area between tank and frame.
•  Our frame adopts anti-rust aluminum alloy
•  All ports of tank are well considered to meet the demands of customers, they are available for all accessory, special request from customer can be acceptable and customer made after checking by engineer.

Remark: we also offer a high quality components for customer choice : assistant filling tank, electric resistant, controller and magnesium bar.

Focus points: Instant heating energy is from main tank which energy getting from the collector .The difference between main tank and instant heating copper coil is about 5°C
