Heat Exchangers Can Recapture Heat Going Out The Chimney
Saving money spent on fuel can be as easy as installing the right heat exchangers. A thermostatically controlled fan driven heat exchangers installed on your flue pipe can retrieve thirty percent or more of the heat that would otherwise be lost out the flue. An insulated flue made from triple wall stainless steel and properly installed with heat barriers anywhere the flue goes through wall, ceiling, or roof provides for safe heating for your home.
Always install a proper flue cap to prevent birds and rain from coming down your flue and into your stove. A hi-quality stainless steel cap will cost fifty dollars or more but will last twenty years or more.
Chimney brush kits usually contain everything necessary to maintain a clean safe flue system.
The interior flue from your stove to where it exits the building is usually made from single wall pipe and is where the heat exchangers are incorporated. About halfway between the stove and the ceiling is generally the best place to mount the heat exchanger, see manufactures instructions accompanying your unit. Most forced air thermostatically controlled units will easily plug into your 110-volt electrical outlet.
A Clean Well Maintained Flue Is A Safe Flue
Chimney brush kits make cleaning your own flue a fairly easy way to protect your home and heat exchanger investment. Check your owner's manual for proper cleaning of the heat exchanger.
The right chimney cap can be easily removed and reinstalled when using your chimney brush kit to remove soot and tars from your flue. Flue cleaning should be done at least once per year.
I have had the same stainless steel triple wall insulated flue pipe and cap for more than twenty years and it appears as good today as when I bought it.
My outer flue is eight-inch triple wall. My inner flue, from my stove to the ceiling mount is six-inch single wall, with the ceiling mount being a six-inch to eight-inch reducer. There needs to be a heat shield in the wall or ceiling where the flue exits the building.
The chimney brush kit that I made up for my flue includes a six-inch brush, an eight-inch brush, two ten-foot sections of ¾ inch PVC pipe with ½ inch pipe threaded adapters glued on both ends one threaded into a galvanized sleeve. The brushes are threaded on one end to receive ½ inch pipe. Your kit will be determined by the inside diameter of your flue and the length needed to clean from the top of the flue to your stove. Ten-foot sections of PVC pipe should be used so you can assemble it as you insert it into the flue for far greater ease of use. I leave one of my brushes threaded onto each pipe when I store them keeping them together in one place.
