Detailed Product Description

Evacuated tubes convert solar energy into thermal energy that is transferred to copper pipes by an aluminum fin with high solar energy absorption and low heat radiance loss.Liquid (pure water or glycol solution) in the pipe heat up,and the heat pipe conducts thermal energy to the water inside the storage tank through internal copper coils. Uses an electrical heater to heat water during cloudy daya or at night.As the water temperature can be adjusted using an automatic controller,user can get hot water all day long.
