Ok now that we're just about done signing stuff and talking to every government agency known to man, I may fire up the welder soon.
Should I use a different wire or shielding gas for the firebox? Or just standard. 035 mild steel wire? We are already running mixed gas (diamond shield or something they call it from Praxair )
I only wanna do it once.
I'm thinking I want the blower to force air around the firebox a crossed the long side of the firebox. Instead of along the length. Giving more time and surface area to heat the air.
But also considering 3 smaller blowers that could blow long ways and be turned on in stages.
The latter thinking, in my overly complicated mind, the blower handling the actual top of the firebox could handle keeping the house warm when it's warmer outside. And that may keep the fire stoked up a little better so it doesn't smolder out. Then the other 2 would be wired together to come on when the furnace is running full tilt and the one blower can't keep up.
Effectively It sounds more efficient to do multiple blowers. Less energy, a constant good fire (I don't want my wife to have to relight at 2 am when I'm out plowing ) and progressive heating ability.
