Another Surdiac Thread

PostBy: NHFarmer On: Wed Jan 01, 2014 10:05 pm

I am joining the ranks as another Surdiac owner. I have read as many posts as I can find on these stoves and have learned a lot. I am impressed with the heat output, but not the burn times. Being a wood burner, it took me a while to figure out how to light and maintain a coal stove. Thankfully I found this site as it has helped immensely. We are using this stove as the primary heat source, and as cold as it has been lately, it needs a good shake down every 3 or 4 hours to keep the heat output. Its actually my brother in law that has been running the stove and lately he has been spending too much time tending. So at lease for this season it will be the Surdiac but time will tell for next season.

Good to have you here NHF. I see the chimney in your other posts, and understand better now. Looks good. i was curious of your history with that particular stove. I was told these stoves "need" to have a baro-damper to work properly. the few people I know said they didn't have problems with their burn times. I didn't notice if your installation has any damper at all.

The Surdiac cult is growing! That's good,maybe we can get these running to peak performance yet. I am getting alot of experiance working a coal stove. Joeq, have you tried burning straight nut coal?

I tried mixing pea and nut, but as mentioned above, it just clogged my hopper. I tried it a couple times, in 2 different seasons, with the same results. Tonite I pieced together a modified stove pipe, a few inches longer than what's in there now, and mounted the baro. Haven't installed the assy yet, just made the pipe. Once apart, I need to put the MPD in the assembled baro pipe.. Next time the stove is down, I'll swap to the baro, "with" the MPD also, and see if a lesser draft will help my burn times. Are there any other Surdiac owners out there with this set-up?
I believe this also has been covered on this site, but I did another little experiment yesterday with my manometer hook-up. I usually have it hooked "B4" the MPD, (on the stove side), and was wondering with my MPD closed, would the draft be stronger on the chimney side. It was reading -.06-07 stove side, and when I read it "behind" the closed MPD, it still read the same. I guess the flow is heading straight thru the closed valve. ;)

I'm no expert on draft but if I understand it correctly you want to measure it before any dampers as that is more like what the fire is actually seeing. So between the stove and the damper. I just came back from checking the stove. Outside it is 4*, snowing and a stiff breeze. Inside it is 70*, breezy and only a little snow around the door, and the stove is ripping. We aren't trying anything different tonight so it will be a couple of late night shake downs and all is well. It seems like about 4 hours is the longest we can go and still maintain good heat output. When I just left, the stove top was running 450* which is about max as far as output is concerned. One problem that we have is the glass is loose in the front door which is letting some air in. My thought is this might not be helping us with burn times. I don't know if this is a big deal or not.

I was also wondering if loose glass would make a different in draft. I have a couple of the glass panes that when running real hot I can notice a gap between the panes. The gap is not big, kinda like a hair width but there is a miniscule gap. I got mine running pretty hard tonight. My stack temp is at 300 degrees and the stove is realy making heat. When this stove is running good it does make some heat. But the magic number is 5 for a shakedown if you want it to make some serious heat. I shook mine down at 5am today and got home at 5pm. The stack temp was 80 degrees and I could not see any hot coal. When I started shaking it down red hot coal fell out of hopper and I was off and running good. The stove can go 13hrs between shakedowns and I have never lost a fire. But, if you want it to keep making good heat you shake every 5 hrs. Right now in Southern,VT it is 7 degrees and dropping.

Gentleman, seeing we're on the subject of the individual glass panes, I was told a good portion of the heat from these stoves, radiates thru these doors. Percentage wise, they say small #s, (like about 3%), but on my stove, when she's cooking, I feel a ton of heat coming out there. More than any other part of the stove. I can't hold my hand a foot away more than 5-10 seconds. So I did a little experiment today, and suspended a thermometer about 3" in frt of the glass for about 5-10 mins. Unfortunately the temp only went to about 350* max. Would it go higher if it was left longer? Didn't appear it would.
And how much does it affect the draft? Tonite, my manometer is reading -.05-.06. If I open the door a couple inches, it only drops about -.03 inches. So the concern about how much the small air gaps between the panes affect the draft? I would say minimal. But my 2nd stove had some severely distorted panes. So bad, I wouldn't even try to run them that bad. Woodsman has them for $6 a pop, so they are available. I had to do 6 of them on my stove.
I think our stoves are similar in burn times. My 513 will make OK heat, on med ( thermostat setting #1 1/2, on a single digit temp like tonite), and will run unattended for the same approx. 5-6 hrs, then will slowly slow down, and be retrievable in about 8-10 hrs. Not sure if I could save it in 12. My baro is my last course of action, to add a touch more life to this thing. It's roughly what the manufacturers rating is anyway, and I'm not expecting too much more from it. It isn't often some-one isn't home here, so if a little poking now and then, and top off the hopper is needed, I guess I'll live with it a while. As long as I can save it in the mornings, through these cold spells, it beats oiling the house.

If anyone with an identical stove to mine, which includes the Harmony 3 stove model, the Bayard model, the Coachman model Nestor Martin/surdiac/Efel, or whatever you want to call them, wants a one piece glass, contact me and I will send you the info to get it cut exactly the right size. Ive forgotten the cost but not cheap. I think around 100 and it was the thickest I could get.

Hello Gentlemen. I am NH farmers BIL. My Question to you is How much square footage are you guys heating?I am heating a 1,700 square foot drafty old barn. What I am noticing is that is when the temps are above 20*, the stove heats great, but when the temps get much below that, it starts to struggle.I don't want to be a slave to my stove . im shaking it down every 2 hours when the temps are this cold.it was Negative 6* this morning and inside the barn was 68* (with my alternative heat running).I too as NH farmer are new to heating with coal, and welcome any advice that can help my stove be as efficient as possible.

I have my Surdiac in my basement, letting heat radiate from basement to first floor. I am trying to move the air with a few small fans. I agree, when under 20 degrees outside you definately have to shake her up often to keep making some heat. I am trying to heat 1400 square feet. I have been making this stove work quite a bit the last few days. At 5am this morning I had -15. If I had like November temps I think the stove would keep up well. Eventually I will get a different stove that will fit my application a bit better.

Another Surdiac welcome. Once again, (and yours isn't the 1st), to be polite, it would be respectful to start a new thread for your particular circumstances. We're getting a pretty good crowd here recently, with these stoves, and I 'm starting to get confused who's who.
you didn't mention what model or size stove you've got. I've got the smaller 513, and it's rated at a low 30,000 BTUs. My drafty old farmhouse only spreads out a measly 1600sq/ft, and my stove will easily keep both upstairs and downstairs comfortable...when the temps are in the high teens and above. I haven't had too much of a need for the single digits, (like the past couple days), and have needed to crank it up a notch. And it is working. The problem, as most people have, is keeping the coal from producing this nasty by-product called "ASH". Once we can all get together, and figure out a way to prevent it from happening, we'll all be much more content.

Just saw the Surdiac thread and thought I'd ask a couple of Questions. I've been rebuilding a 713 that has been very gently used but had to replace the glass. I bought a new single piece of clear PyroCeram to replace all of the broken glass pieces. Will this affect the operation of the stove? Does the draft depend on the hair line spaces between all those glass pieces? I won't be able to test her out until next season but any help would be appreciated.

No the draft does not depend on the glass. there are a number of holes drilled into the door frame to supply secondary air.
