barometric damper
hello all

i had a house inspection done this week, and the guy who inspected my wood furnace suggested that i install a barometris damper on it, he said this would help with the furnce to burn better, has anyone got one of these on their wood furnace, if so doe sit work

many thank sfor your help
paul :)

I use them on gas furnaces and it is the same princaple. They if set up correctly better controll the combustion / draft through the appliance. I have never worked with a wood burner but I assume it is the same.

I had one installed one on my wood stove last year but I had to remove it and replace it with a regular damper to get better control of the fire.
Now my stove is older and not as air tight as newer ones so that may have been the problem I was having with it.

i was told that these are supose to help the wood furnace burn better and hotter, but i have also heard that they arnt that great, really dont no what to do :furious:

I would stay away from them. Different types of wood (wet/dry etc) require different draft etc. They are meant for oil or gas burners with a constant fuel and BTU rating. I did LOTS of oil and they can stick open,closed make noise etc etc. On a oil or gas unit we set them with a draft gauge over the fire, not feasible with wood.

I have seen homeowners cap them and/or stuff them with insulation.
Can't say I've ever seen a draft regulator on a wood furnace.
As Yuri says, probably not a good idea.

T-shirt weather here Yuri.

Unless you use a consistent type of wood. With roughly the same BTU content.
Or, have a very strong draft. They can cause more trouble then good.

A manual damper allows you to regulate both the draft in the stove. And how much air is removed from the room/house.

A barometeric, removes large amounts of air from the room/house. And can cause you to use more wood. And have a much dryer house.

ARGGH!! My tinbasher friend is rubbing it in again. :boxing: Going to the deep freeze weather next week. Good for generating biziness and $$ revenue. The barometeric idea is not good, stay with a manual damper or you may end up with a cold chimney and creosote buildup etc.

Thanks for the compliment.
I have a 'friend' who calls me 'the senile old tinsmasher'.:(

thanks guy's i dont have anything on it at the moment, the furnace is down in the basement, and the chimley exits from the basement up into the garage and up through the roof and out, there is a draft flap sort of thing on the front of the furnace :eek: sorry to sound blonde, but not used to all this, we are from the uk where we have gas central heating :thumbup:

Could it be a combination wood/oil furnace?

paul1969f 12-03-2009 04:25 PM

no just a wood furnace

I would not recomend using one, Barometric dampers are to be used only when there is a (forced) draft being used over fire....such as an oil furnace where there is a consistent draft exiting the chimney. It would almost be imposssible to set the barometic up and keep a consistent draft when your not working with the same (BTU Rating) or (same) temperatures like you get with oil. I would not use one on gas eithier... I would use a thimble instead.... because once again you don"t have an over fire (forced) draft.

Barometric dampers are common for wood stoves, and help to control the draft over the fire.
