New Viessmann panels – overheating a thing of the past.

200-fm The new Viessmann 100 and 200-FM solar thermal collectors have incorporated a “ThermProtect temperature shut-off” feature into the selective surface coating on the copper fin. The special coating changes its molecular crystalline structure as the temperature increases, and causes it to increase the rate of heat emission. This prevents the collector fluid from forming steam and going into a critical shutdown stage, with lengthy periods of stagnation and its detrimental effects downstream. As soon as the collector temperature lowers a little bit, so the changes revert, allowing the collector to gradually begin to absorb heat once again. The benefits are impressive. Extending the life of the glycol (if present) in the heat transfer fluid, and higher efficiency in the panels, and extended life of the remainder of components from extreme high heat conditions. It’s a game changer.
