Features: 1) Solar water heater 2) The inner has the copper coil for heat exchangers 3) We have got European patents

Thermosiphon solar collectors provide Mains Pressure pre-heating via a high efficiency copper coil heat exchanger installed within the solar collector tank. The way in which the Mains Pressure solar collector heats water is the same as the non pressure solar collector. Instead of using the water in the tank directly, as the Non pressure does, the type uses a 45¡«60 copper coil heat exchanger inside the tank which provides more than 1.2m² of heat transfer area. When water flows though the coil, it absorbs heat from the water inside the solar collector tank. The solar collector tank is therefore for thermal storage. One advantage of this system is that almost no water is introduced into the tank (apart from occasional topping up), so corrosion and scale buildup are almost totally eliminated. Tanks are designed for low to medium pressure applications, using a gravity feed tank or pressure reduction valve. Direct connection to Mains Pressure water supply is not permitted. Please check your local building / plumbing regulations regarding the installation of water tanks.
