Features:

1) Tri-elements coating by N/SS/Cu of vacumm tube. Higher heat absoption effciency. 2) Copper coil inside of tank could bear high hydraulic pressure, providing more comfortable shower3) Enjoy the fresh hot water exchanging heat energy from tank, more clean and healthy. 4) Easy operation and fashionable design, economical and environment protective performance

working principle:

cold water flows into water tank and becomes high temperature via heat absorbing from vacuum tube.

when you want to use, another cold water crossed from coiler which could exchange heat energy with hot water inside of tank, you will enjoy more fresh and high hydraulic hot water out from the coiler.
