Principle |
 |
DP Series Heat Pipe Vacuum Tube Water Heaters consist of SEIDO1 with two sides coating - heat pipe vacuum tube collector, stainless steel water tank and angle steel support frame with spurted plastic coating. The condenser of the heat pipe tube is directly inserted into the non-corroding copper protection tube within the water tank. The heat pipe vacuum tubes collect heat with high efficiency transforming over 92% of the incoming solar irradiation into heat. The condenser transfers the generated heat to the manifold where the water is heated. Thereafter, the hot water is circulating in the system until the system attains the required temperature. The heat transfer liquid of the heat circuit does not flow through the collector itself. This allows a very simple installation and guarantees an exceptionally trouble-free operation. The operation of the system will not be interrupted even if one of the collector tubes should get damaged. |
