Collector plate non-pressure solar hot water heater 

Product introduction

Non-pressure solar water heater is such a kind of thermosiphon solar water heating device, which flat plate collector placed below high pressure hot water tank. The tank and flat plate are connected with two circulation pipes to form a open-loop solar water heating system, tank is non-pressure design, based on gravity. The whole system only use water, can’t use other liquid as circulation medium. By continuously circulating in this way, the water is heated directly inside flat collector and rise to be stored inside hot water tank.

Certificates: CE,CCC, ISO9001, ISO14001, ISO45001,Safety Production License

Non-pressure flat plate solar water heater characteristic:
1.Freeze resistant: The flat plate collector is equipped with antifreeze as the internal heat medium, so it can transfer heat quickly in cold weather.
2.Safety: the collector is made of toughened glass, suitable for long-distance transportation.
3.Bacteria-free hot water, pressure-bearing use: open tank heat storage, closed coil heat exchange for water, hot water is ready to use, fresh water, no secondary pollution, no harmful bacteria.
