Wanfa Электрический водонагреватель

Due to the variety of water quality,a kind of special nanotechnology material ,which is nontoxic and environment-proctecting, is anhered on the surface of the inner-tank made up of SECC, so as to protect the inner-tank forever. The whole 360°C Foam Protecting Technology The Polyurethane foam embase the whole inner-tank and leaves no gap,to advance the performance of hot insulation greatly. The Low-Level-Affusing&Cycling Equipment During the time of heating,the uper-layer’s Temprature in the inner-tank is higher than the lower-layer’s.So we use a low-level-affusing&Cycling equipment to keep high themprature lasting. More Protection Technology for Safety Protection of dry-burn,Protection of over temperature,Protection of over-pressure, Protection of water flow back(refluent).
