How It Works
Using our patented dual flow system, No Frost Venting's Plumbing Vent Stack Kits collect heat further down the stack and release it right at the top. The closed loop system is filled with refrigerant that changes from liquid to gas as it is warmed lower in the stack. During the physical change from liquid to gas, the refrigerant efficiently moves the heat from down in the sewer stack to the top of the vent kit.
The colder it gets, the better it works!
