BK Princess install

[bobdog2o02]

I have some questions on piping this new stove. I have 15' insulated class A starting at the ceiling of my basement going through the 1st floor and out the roof of my ranch house. My dealer sold me new single wall stove pipe to connect to this chimney system. I have heard a few places that this should be insulated too? What are everyone's thoughts, i dont mind spending some extra $$$ to make it right and efficient.

The manual suggests doublewall stove pipe if I remember correctly.

The connector pipe from the stove to the ceiling in your basement does not need to be insulated. Double wall or single wall connector pipe is what it is called. It will be black. Double wall connector pipe is preferred because the interior is stainless steel so it will last forever, it fits better with no gaps or seams, it is allowed to be closer to combustibles, and it drafts better because the smoke passing through it is not cooled as much.

I have double wall on my princess and have been pleased with it. It's a long life product vs. the cheaper single wall that often only lasts a few years.

Thanks for that

I just got done talking to a BK rep on the phone. double wall is not required but will assist draft if i have problems. I think i'll go with single wall so i can get the radiant heat off of it and add btu's into the house.....

The stove is what heats the house. The pipe, especially on a BK, needs to stay warm to encourage draft. If you need that extra heat from the pipe then your stove is too small.

I understand that the single wall is cheaper, each time. I have single wall on my non-cat in the shop. I used it to save money and to get more heat out of the stove. In the shop situation, the stove can never be large enough so I plan to steal all the heat I can get from the pipe while running the stove at 750 and still keeping up adequate flue temps to avoid creosote formation.

Other than saving money on initial install, I see no reason to prefer single wall on a house stove.

The stove is what heats the house.

I believe the pipe can make a significant contribution. Just ballpark, think about the fact that the surface area of the pipe is not at all negligible compared to the surface area of the stove, and a single-wall pipe is generally not much cooler. And those two factors pretty much determine how much heat is transferred into your house.

The pipe, especially on a BK, needs to stay warm to encourage draft.

A given installation may need double-wall for it to stay warm enough. Or not.

If you need that extra heat from the pipe then your stove is too small.

I would agree with this statement, technically, but per my first comment, even if you don't need the extra heat, it may significantly increase your efficiency.

Other than saving money on initial install, I see no reason to prefer single wall on a house stove.

Other than efficiency, another nice thing is that, if you like to clean your chimney from below, it's a lot easier to R&R single-wall pipe.

My rec to the OP is to try single-wall and see how you like it. It IS mighty cheap, so if you don't like it, not much lost.

Your stove is going to frequently run with cooler than average flue temps. In this case it's not a good idea to try and scavenge a little more heat from the pipe. You want the flue gases exiting the chimney at over 250F. If the gases are cooler they will condense in the form of creosote. Double-wall connector will still radiate some heat, but can make a nice difference in the exiting flue gas temps. If you want more heat, stop losses in the basement by fully insulating the walls and rim joist area and sealing the sill plate.
