Solar water heater

The characteristic of vacuum solar collectors is that they have a higher efficiency level in autumn and winter than standard flat surface collectors; the efficiency of these collectors is lower than flat surface system in summer. Vacuum collectors are particularly suitable to integrated with low temperature room central heating like wall or floor systems or also for high temperature. The characteristic of vacuum solar collectors is that they are made of vacuum glass tubes with a high efficiency selective coating; the central part of these tubes’ is entirely of copper. The basic characteristic of these panels is that they have a curved transparent absorbent surface that allows collectors that are not positioned perfectly towards south to offer the same results as if they were. Himin heat pipe solar collectors have Keymark certificate and satisfy EN12975.
