POUR HEAT PIPE HAS A FEATURE THAT MAKES IT UNIQUE WHEN COMPARED TO ANY
OTHER EVACUATED TUBE ON THE MARKET TODAY:
When the hot water storage reaches its maximum temperature, the solar pump stops and additional heat will not be removed from the collector. This will cause the tubes to become very hot. To protect the glycol in the manifold, our heat pipe tubes have a patented thermostatic control device. This activates automatically in the condenser head and prevents the temperature in the manifold from becoming hot enough to damage the glycol.
We offer two options for the unique temperature limitation device. When the temperature rises to 90°C/135°C, a stack of bimetallic disks flexes, closing a valve that will not allow additional steam from the heat pipe to enter the condenser head.
When flow is restored to the collectors and the temperature falls below 90°C/135°C, the disks snap back and the valve reopens restoring the system to normal operation.
