solar energy projects Product Description              What's pre-heated solar energy system?       SKI-NTA series pre-heat solar water heater is also called copper coil solar water heater, which is a kind of thermosiphon solar water heater with pressurized hot water using. A pile of heat-exchanging copper coil is pre-installed in the hot water storage tank with two connections as inlet and outlet, pressure cold water goes through copper coil and all the way it absorbs heat from hot water in storage tank, in this way at copper coil outlet we get instant pressure hot water continuously.               What's the model and specifcation of our solar energy system?
