spacification
1- Inner tank : SUS 304 //SUS 316 , Thickness 0,5mm //0,6 mm
2- Outer tank : A grade color steel
3- vacuum tube : Adopting the three -hight vacuum tube its absorb rate is >94% and its thermal radiation rate is <6% (100 degrees)
4- frame : coat galvanized steel sheet 1.5mm
5- insulation : imported polyurethane insulation thickness 50-55mm
6- heat exchanger : copper coil pressure resistance
Advantage
1. Using the cooper coil as the heat exchanger , it can produce hot water with constant temperature , it is safe and comfortable to use
2. It takes the advantage of the tap water pressure , can produce strong water flow
3. the cooper coil heat exchanger makes the water heated rapidly, and it is not limited by the tank capacity so it can produce more hot water than general models
