Компактный солнечный подогреватель воды под давлением

compact pressurized indirect/ closed loop solar water heater Highly absorptive with an average daily performance efficiency over 50% ; Quick start-up, heat pipe transfer the heat energy into the storage tank in single direction. Withstand pressure of 0.6 MPa, can be connected directly to city tap water system. No water running inside the evacuated tubes, the water heater can be still in service even with several tubes broken; Highly efficient insulation with polyurethane foam; Simple structure, easy to assembly and install, diffusing light reflector can be assembled easily with its module structure; Can be used all year round in cold climate; Can be used together with auxiliary electric boost; Service life as long as 15 years;Environment-friendly,power-saving Working principle: One copper coil is installed inside the tank as the heat exchanger. When water flows into the copper coil.it absorbs the heat of the water in the tank via the copper coil therefore the water tank is just a heat storage tank.
