lowest solar water heater

A 50/50 propylene glycol and water mixture from the collectors through a coil of pipe in the solar tank, and then is pumped back through the collectors. The potable water is warmed by heat transfer through contact with the pipe. These systems are pretty much the only choice in very cold climates. When there is not enough energy for sun, an electrical or gas back up element will be automatically switched on by controller.

1.Outer board: aluminum-alloy 
2.Main pipe of U-type tubes:22*0.8mm,branch pipe of U-type tubes:8*0.6mm
3. Temperature-warmth layer:mineral wool OR by polyurethane 
4. Bracket:Aluminium-Alloy , thickness 1.5mm 
5. Vacuum tube : 3-HI solar vacuum tube ( length:1800mm,diameter:58mm or Length:1500mm, diameter:47mm) 
 

1.Solar collector could be put with any angle, could be used for balcony type 
2.Can operate with water pressure up to 0.6MPa 
3.Can be combined with existing energy source 
4.Storage do not need be installed above the collector

1.Simple Installation, no maintenance, effective operation 
2.Easy retrofitting to existing systems 
3.Suitable for single and multiple solar heating application systems 
4.Preferred option for extremely cold areas and questionable water quality 
5.Incoming potable water is routed to the solar storage tank 
6.Porcelain enamel or SUS316 stainless steel storage tank with electrical or gas back up 
7.Double-walled copper coil heat exchangers in storage tank prevent contamination of household water
