Down draft issues - woodstove


You might want to ask your question at Hearth dot com. There are a lot of people there who really know stoves. I'm not one of them, but here are some ideas running through my head:

That chimney on the outside of the house is double wall insulated pipe, right? Feels solid if you thump it? Usually you have problems with chimney's not drafting because they're A) too short, or B) too cold (not insulated). But if that's insulated pipe, then you don't seem to have either problem.

On your picture you label the thing on the stove pipe as a "thermostat." Did you really mean thermometer? As in something that's just stuck on the pipe? If there's something inside the pipe there you may have found your problem.

My stove only has about 10' of chimney (plus six feet of stove pipe) and the draft is excellent.

Your two 90 degree bends are hurting you. I don't see the trees making any difference -- it's not about wind, it's about warm air rising. It doesn't seem like adding another section of chimney would help dramatically, and you would probably need to support it (three steel wires).

If you have cold air dropping down the pipe, then were is the warm air going that it is displacing? Opening the windows will probably aggravate your situation, because the heat in the room will rise out of them, and suck more cold air down the pipe.

What do you use to start your fire? Next time start one with a lot of good, dry kindling. The idea being to get as much heat with as little smoke up the chimney as quickly as possible.

Where does the smoke exit the stove?

The insulation in "A"-vent is an 1" air space, the flue piping is not packed with insulation. This is why the chimney can't get hot enough to start the draft.

The pipe outside looks like "all fuel chimney" to me. The pipe when not being used gets just as cold as it is outside.
If the pipe is on the north side in the shade it stays cold. The higher the pipe the harder to create a draft.
All fuel chimney has insulation inside and is very heavy and i believe only comes in 30" lengths.

Mine is insulated. My chimney has an inch of mineral wool between two layers of steel. It stays cool to the touch, even when there is a raging fire burning. According to this guy, they all are:

He has not said what type pipe he has installed. It may be the insulated pipe.

Do you have another chimney in the house? Is it higher than this one? They will often work against each other if you do.

Yes, thermometer. It's a magnetic one stuck on the pipe.

I used very dry cedar and cardboard.

Through the back and through the damper.

Yes. There are 3. One for the furnace and hot water heater(oil) and the 3rd probably doesn't matter as it is for a propane furnace in the garage.
