Anti-reflection glass
Wagner & Co sunarc anti-reflection glass for its collectors.  The ultra-fine nano surface structure increases the transmissivity from 91% to 96%.  This way the heat yield increases between 6 and 10%.

Speed controlled CIRCO solar pump
The speed controlled circulation pump constantly adjusts the volume flow of the solar circulation to the solar irradiation.  A triac triggers the number of half-wave alternations according to demand.  This reduces the electricity uptake of the pump as well as heat losses of the collector.

CONVECTROL
The innovative convection brakes reduce heat losses at the pipe connections of the solar cylinder by up to 50% each.  The patented barrier design separates the cooled water in the connection pipes from the hot storage contents.  Annual storage heat loss is thus cut back to around 10 to 12%.
