The Spirovent was selected and installed to prevent dirt and sediment in the existing system from reaching a new addition and improvements went even beyond that.
After having tried numerous other methods, the first Spirovent was installed in Carman Hall to deal with a long history of no heat calls and clogging valves.
Install the Spirovent® at the point of lowest solubility, which is the place in the system where the temperature is the highest and pressure the lowest.
