Would it be beneficial to put a rheostat on her?

Don't think so, at least in my application. The stove is centrally located so the heat goes upstairs as well as around the 1st floor. Maybe in a situation where the stove is in a more enclosed area, but I would be more inclined to use a 110 volt plug in thermostat instead.

i used the T118 one from this page with my Mark III fan. I didn't want the fan to stay on if the stove cooled down, this worked well for me.

This is an EPA legal stove for emissions when it was made, the over-fire draft creates secondary combustion in the upper chamber, so there's less CO NOX CO2 etc. byproducts coming from the chimney. It won't be raked/filled again until tonite.

this Harman has been running like this for over a decade now. The pictures and vids show why the Harman doesn't need a damper. The glass vents draw in if when the flue velocity gets high, to hold the draft setting at the ash door under the fire steady. The built in baffle is an effective heat exchanger passage, the fan extracts maximum heat from the exchanger when plugged in, if need be.

Great, vids,

But I see you still can't help throwing more misinform into every post. There are no" EPA legal" coal stoves. Even Harman's own customer service confirms that coal stoves are exempted by the EPA from regulations, therefore nothing to be legal with.

If you want to educate others about your stove's benefits, you might consider sticking with what you know as fact, not shooting from the hip.

I used this t-stat to run the zone in the kitchen before I connected the switching relay and the 24 volt t-stat. It switched the circulator on and off. Plugs into the wall and the load plugs into the back of the plug.

Fred,
Your place is like mine, long, with lots of rooms with connecting doors. Have you given any thought to those small, through-the-wall fans ?

They worked well for my sister in her house (New Hampshire winters) to help circulate heat from a stove off on one side of the house.

Yup, key word - "exempt".
When I couldn't find any regulations for coal stoves at the EPA website, I called Harman and that's what they just told me.

Not through the wall, but I have fans in both archways exiting the stove room that work well--in the pix, the CUTE one ain't worth the packing it came in, BUT the UGLY square one moves some heat around--funny how that is quite often the case

Thanx for the suggestion Paul

Reason it hits home is, before I got the coal range 8 years ago, I did alot of on-line research about getting as high efficiency a wood stove as I could.

In the process, I also came across info about coal stoves being exempt from EPA regulations. Mention of it in this thread got me wondering if that was still the case and it is.

Yup, she had one of those door frame corner fans and said pretty much the same thing about them. That's why they put in the wall ones with more guts.

I would say so !

That's one way to get folks to take their hats off indoors !

That exemption is probably why your "not supposed to" burn anything but coal in the unit, according to the tag supplied with the unit when new.

You all know what I say to that ....

That is an easy fix..
I actually did a little more.
I have a fan speed control switch, plugged into a Target 24hr. timer.
The timer's recepticle, is switched.
The top one is hot all the time...
For the vac..
This gives a LOT of options...
I can set the blower speed to nearly whatever I want,
and I can cycle it , when I want.
For instance, it isn't all that cold here now,
so I have the blower on pretty low speed,
and it cycles 15minutes on, 30 minutes off..
The timer has a bypass on it, as does the fan control.
So you can run full on, all the time, if you choose.
Or off completely.. without ever unplugging the blower motor..

well it's 9:09 PM and I still haven't even opened the door on the stove since this morning, my son has the fan plugged in while he's browsing his Ipod and Android phone next to the stove. Getting ready to rake down and fill the Harman Mk I for the night within the next hour or so.
