German coating technology of evacuated tubes, high absorptive efficiency and low emission, high temperature resistant and extremely cold-tolerant
Optional digital controller for the solar water heater to realize display of water level, water temperature and automatic water filling.
Imported painted steel, environment- protection, anti-insolation and corrosion resistant, acid rain etch resistant, stable and no distortion.
Aluminum allay stands: Wind resistant and corrosion-resistant, durable and long service life
Volume of storage tank: Look at the table below.
1. Keep a constant temperature of water in the tank.
2. Avoid the promblem came from water level controller malfuction which could cause water flow out.
3. The effect of temperature preservation can last 72 hours.
4. Without incrustation, its life-span is longer.
5. It's the real drinking water quality and promotes life quality
6. Water wouldn't run in the tube, so the heat delivery efficiency wouldn't be affected.Direct-Plug Unpressurized Solar Water Heater (CE)
