My Harman dealer says not to go with outside air, unless in mobile home, which I'm not. House done in 80s', & addition in 90's. Looking at closer vent clearance with OAK. Going to talk with them when I pick up stove, P38+.... Thoughts..
gfreek said:Right... Can I use Selkirk Direct -Temp pellet pipe with outside air/vent with any stove, Harman?? Can anyone recommend online dealer??
Has anybody thought it might be a good idea to heat the the OAK with the exhaust gas?
nosaudioil said:Whatever, regarding the OAK. I know that my stove now works better in every way with the outside air intalled. This is after running the stove for the 2.5 previous years without an OAK.
rona said:If your air for combustion is always at a certain temp such as the inside air of your home the stove will have less burning problems.
When you are bringing outside air which can vary from +40 to -30 in to burn there will be a big difference in how the stove runs and it can create problems. Your dealer doesn't want to be called back for service work so he will recommend inside air. It is also a extra cost that could break a 'deal".
Cold air holds more oxygen then hot air and you should tune the stove accordingly to get the best heat out of your unit.
I would never install a stove without outside air as I hate to waste heat.

That is true about the temperature of the outside air making a difference. Also if the outside air contains moisture, that can cause the ash in the burn pot to cake up. I have almost a 15 foot OAK to help temper the outside air. I am also thinking about creating an air tank with a trash can to help warm the air like an Indirect Water tank on a boiler.
Still by using an OAK the house warms up faster and stays warm on one lower heat setting than without the OAK.

Has anybody thought it might be a good idea to heat the the OAK with the exhaust gas? Simple experimentation could be done by simply getting some more tubing and laying it in front of the exhaust and allowing it to heat the tube to see if it makes any difference in the amount of pellets consumed.
I just purchased a new stove and was rather taken aback by how hot the exhaust gas was during test-firing.
I think there is lots of room there for heat recovery for people with some decent fabrication and a little ambition to stay busy during the winter-doldrums.
With a forced exhaust it would seem you could suck out as much as you want without any negative impact on stove operation. (VS say a stack robber on a wood stove which tends to kill your draft).
Just some thoughts.

Ordered Selkirk Direct Temp Up and Out Kit, vent pipe inner , outside air outer pipe. Ordering vertical pipe, then install. Baby Steps...
