Stove Pipe Temps

Thanks!

if you are using a Baro make sure it is before it how much room do you have between the top of you stove to the Baro and is your Baro on the vertical or horizontal part of you pipe I have mine 6" below my Baro the temp will be hotter before the baro then after the baro

LsFarm wrote:Gary, the probe has to go in the area you want to monitor the temperature of. So the probe to measure the flue temp needs to go in the flue pipe.

Yup, I got that.

Understood.

LsFarm wrote:I think this will answer your question... ?

Nope.

Do I put the probe inside the flue 10 feet away from where the gases exit the stove? Or do I put the temp probe in the flue just an inch away from where the gases exit the stove???

You vote! See pic! Put the probe at position 1, 2, 3, or 4?

Oh....And Berner....I don't have a Baro.

OH !! OK, now I understand. Sorry, I'm rather slow at times.

I don't think there is any hard and fast location in the flue pipe. Just like JC said, before the Baro if any.

I think you will find only a little bit of temp difference from where you locate the probe. If the probe is in the center of the pipe. The pipe will shed heat, but the heat in the center will be pretty consistant even 6' from the stove.

I use the temp as a 'tool' to tell how hard my boiler is 'working'. The temp tends to rise the longer the stoker is burning, and as the water temp rises, the exhaust gasses get hotter. You can use the indicated temp to 'fine tune' your air adjustment. It should also tell you if coal from a differnt source is higher or lower BTU content.. So I'm not really concerned about the absolute reading as much as how it compares to previous readings under different burning circumstances.

I located mine about two feet from the stove exit. I see from 225*-450* depending on how long and how hot I'm pushing coal through the stoker.

ok then 12" to 18" above you stove on the vertical no baro do you have a manual damper if so put before it same has you would if you had Baro if you have a power vent then 12" 18" would be fine or anywhere between elbow at the bottom if you have one and the top elbow

thx been wanting a remote temp probe so picked up the maverick on ebay - we'll see how it works for keeping an 'eye' on things in my basement.
the old pc w/web cam sounds like a good idea too
I'd also like to get the cole-parmer unit mentioned earlier - EW-90205-26
Panel-mount Remote Probe Thermometer

and yep I know old thread but nothing wrong with livening it up a bit I hope

I have the Maverick with the dual probes so I can monitor my boiler remotely on two

different probes. I monitor the boiler water Temperature of the boiler and the flue

pipe above the boiler on the outside of the pipe, because the temperature reached

inside the pipe is more than the probes are rated for. I also have bought a second

unit that can be placed in different location in the house (upstairs) and the one

sending unit send info to both units. It is a little harder to start the senders up

you have to turn on the sender and quickly turn on each receiver to get them

synchronized.My boiler is now at 165* and the chimney is at 134*.

I set the first probe to (B) eef ...really Boiler..... second probe (C) hicken ...really Chimney

They will constantly alternate from one to the other if desired,which I do.

There is also a safety warning built in, if either probe goes above the preset limit

you can set an alarm goes off, I set my (B) to 205* And the (C) to the Max @ 410*

so I instantly know of a problem.I've used these for 4 years 24/7 and have no trouble.

Hope this helps.

Oh yeah, I'm with BigBarney on this one... I knew right away I would need something to monitor temps. Especially when loading coal - I leave the ash pan door open to ignite the fresh coal. Left unattended for any amount of time this could be catastrophic! I secured the BBQ probe with magnets to the flue pipe about 2 feet from exiting the stove. Then the meat probe is actually inside my warm air duct so I can monitor the air flowing thru the duct into my rooms.

This is the Redi - Chek Wireless BBQ Thermometer Set. Its the newest version. The probes are suppose to be able to handle 716 degrees but max monitor temp is a little over 500. The remote displays both probe temps up to 300 feet from the transmitter. It has dual alarms. I set the Hi Temp Pipe alarm at 250 and the low set at 110. The air duct Hi alarm set at 140.

Quite frankly I think anyone that can't sit by their stove while the ash pan door is open should absolutely have one of these. It will even alert me while I'm sleeping if the fire is burning out so I can react.

Do you something between that pipe and the thimble? Looks like a huge gap around the pipe!

Your right. My 6 inch pipe runs thru an 8 inch round flue that I mounted thru the stone wall in my basement. It serves dual purpose. Keeps the wall cool and feeds the room for combustion air. I'm also thinking it keeps a neutral air pressure between the basement and outside so I don't get a down draft thru the chimney.

I've got a DS Machines DS-1600 and it's rated at 130k BUT/Hr. and I've had it at 650* for a few days last season during some very cold days and my stack temp never went above 350*.
