Pre-heat Pressurized Solar Water Heater VPS-SA

SYSTEM DESCRIPTION
VISION VPS series pre-heat solar water heater incorporates a number of high efficiency vacuum tubes, an atmospheric water tank with exchanger, the supporting bracket and accessories.
The vacuum tube for VISION non-pressure solar water heater could be single-target tubes, three-target tubes, super heat tubes, and heat pipe tubes.
The solar vacuum tubes heat enough hot water to store in tank; copper coil inside tank makes fast heat exchanger from hotter water surrounded to colder water running through it, in this way we get instant and high pressure hot water from copper coil end.
MAIN FEATURES
