400L drain back solar water heater system
400L drain back solar water heater system offered by China solar water heater manufacturer Raven New Energy. The drain back solar water heater system is a type of split solar water heating system which has advantage of anti freeze in winter and without over heating problem in summer. This solar hot water system no need glycol circulation, no need expansion vessel, no need pressure relief valve. It is simple and high efficient solar water heater .

Drain back solar water heater for villas features:
Solar collectors are separated with water tank, system works by pump circulation.
Equipped with intelligent solar controller, reliable operation, supplies constant hot water temperature.
Water tank put inside house, avoid rust and last long lifetime.
Solar collector can be installed on the balcony, wall, and rooftop.
Solar water heater system working principle:
Adopt the temperature difference circulation, controller operates whole solar water heater system automatically.
1. Hot water circulation pump will start circulation when temperature difference between solar collector and water tank reaches the set value.
2. Pump will stop circulation once the temperature difference lower than set value.
3. The circulation pump makes heat-conducting liquid circulate automatically
4. The heat-conducting liquid transfers heat to the water tank by a coil heat exchanger.
5. The solar thermal panel will collect energy from sunlight to heat water; there is an electric heating element inside hot water storage water tank, for a backup heating in cloudy or rainy days.
