Chimney Relining

What causes water in a gas furnace flue?

The modern, higher-efficiency gas furnace is a fabulous engineering marvel.

In the old days, low-efficiency gas furnaces sent almost as much heat up the chimney as they put into your home. This pushed your utility bills sky-high and wasted precious natural resources

Today's higher-efficiency gas furnaces extract more heat during the burning process and send much less of it up the flue. But for all the benefits these furnaces offer, there's one important side effect that must be dealt with—excessive moisture in the flue.

You see water is a by-product of burning. In fact, when you burn one cubic foot of gas, you create two cubic feet of water vapor. Those old inefficient furnaces sent so much heat up the flue that the water created in the combustion process stayed in the form of hot steam all the way up and out the chimney.

New higher-efficiency furnaces don't put as much heat into the flue; they put it into the home where you want it. The problem is, the water vapor that's created during burning now doesn't have the draft power no push it up and out your furnace flue. So what happens? It condenses on the wails of your chimney. And unfortunately, no masonry chimney is designed to be constantly bathed with water, especially the acid-laden water found in your furnace flue.

The result is the deterioration we've outlined in the middle of this brochure. Installing a new, high-quality 316 Ti alloy stainless steel HomeSaver Pro relining pipe will vent these water vapors efficiently and with maximum safety.
