Discussion Overview

The discussion centers around the most effective means of moving hot air generated by a wood stove to disperse excess heat into other rooms of a home. Participants explore various methods of air movement and heat transfer, considering both theoretical and practical implications.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether it is better to blow air across the wood stove or to suck air away from it, seeking clarity on the most effective method.
  • Another participant suggests that a fan is generally sufficient for moving heat, but emphasizes the importance of understanding the home's layout for effective air movement.
  • A different viewpoint proposes using a heat exchanger over the stove to improve heat distribution without affecting the stove's burn rate.
  • One participant argues that allowing convection to naturally distribute heat from a basement stove is optimal, while advocating for drawing hot air from the stove rather than blowing air over it to maximize heat transfer.
  • Another participant reiterates the preference for pushing air across the stove for reasons related to heat transfer and fan overheating concerns.

Areas of Agreement / Disagreement

Participants express differing opinions on the best method for moving hot air, with no consensus reached on whether blowing air across the stove or sucking it away is superior. Multiple competing views remain regarding the effectiveness of various approaches.

Contextual Notes

Some claims depend on specific assumptions about home layout and stove design, and the discussion does not resolve the effectiveness of different methods or the implications of airflow on stove performance.

What is the best way to move hot air? Would it be blowing air across the heat source (ex: wood stove) or suck the air away from the heat source?

I use a wood stove to heat my home which works perfectly, but it occasionally gets too hot in the living room (where the wood stove is). I want to disperse some of this excess heat into the other rooms.

Best way in terms of what? If you have already made the heat, then pretty much it stands to reason that a fan is really all you need, right? Are you possibly thinking of something else? It would help to know the layout of your home to find out just what is involved with moving air from one room to another.
 
What I want to know is, is it better to blow the air across the wood stove or suck it away from the stove?
 
Whichever way you do this you will effect the way the stove burns, your best bet (although it not my area so just an educated guess) would be to fit some kind of heat exchanger over the stove then have contained airflow through it vented into rooms or closed system like radiators piped through, this way the waste heat is used to heat the rest of the house and the burn rate of the stove dosn't change.
 
Actually, the best way is to have it in the basement and allow convection to do it's thing. I can't remember what those older systems were called that did this.

IMO it is better to draw the hot air from the stove and duct it somewhere. Simply blowing over a hot surface does not allow the air a lot of residency time to pick up the heat.

For reasons of heat transfer and avoiding overheating the fan, it is better to push air across the stove.
