SOLAR HEATER

Heat tubes utilize an open vacuum tube with an outer coasting tank made of iron painted with PVDF. Water actually fills the inner vacuum tube and is heated internally by the sun. Warm water rises to the top of the tube where it fills the collector and the cold water sinks to the bottom of the vacuum tube to replace the heated water and to be reheated by the sun. PVDF coating (polyvinylidene fluoride) or Kynar® coating is a pure thermoplastic fluoropolymer that is chemical resistant and is unaffected by most chemicals and solvents, and has excellent wear and resistance. Kynar® PVDF coatings also have a high dielectric strength, excellent resistance to weathering elements in harsh environments along with the ability to self-extinguish.

A Flat Plate Collector is a heat exchanger that converts the radiant solar energy from the sun into heat energy using the well-known greenhouse effect. As the plate gets hotter this heat is conducted through the risers and absorbed by the fluid flowing inside the copper pipes which is then used by the household.
