Did you know that energy dollars are escaping out of your chimney?
Traditional dampers are located in the “throat” of a fireplace. These cast-iron dampers do not seal well—they have a leaky, rough, metal-to-metal seal. Recent lab studies have shown that even a new throat damper can leak up to $200 of heating and cooling a year. Imagine how much energy an old, rusted out damper leaks!
These top mount, energy saving dampers seal tightly to save you money! The rubber gasket seals tightly like a storm door for your fireplace, and keeps heating and cooling dollars where they should be…in your pocket! The damper mounts on top of the Boost-a-Cap or on top of your chimney flue to keep animals and rain out and easily operates from inside your firebox. And every time you close it, it seals tight — eliminating any draft!
