Measuring the Temp of your flue pipe???????

[Wormyone]

I have done a lot of reading on this forum and I am amazed at all of the kowledge What is the right place to measure the temp on a stove. Since I have a Buck stove and it has a chamber on the top I cannot use a stove top thermometer and I can not use one on the flue because it is SS and magnets will not work. I have used a IR and get readings between 375 to 500 sometimes. I also saw a post on here saying that you have to double the reading that you get on the surface becasue it is singal wall pipe. Is this true? Also my run is only 16' with 14 of that being wrapped in a insulatiuon blanket. Thanks in advance for the help.

Sounds like this is a cat stove. Does buck have a way for you to install a cat probe thermometer?

If not a probe thermometer is what you want for the stack. Here's an example of a thermometer for the catalyst (broken link removed to http://www.condar.com/cat_meters_woodstoves.html)

Here is an example of a probe for the stack itself (broken link removed to http://www.condar.com/probe_meters.html)

In all, are you just curious to see what your flue temps are? Or are you having troubles / concerns with the stove's operation?

I agree, smart bunch of folks who participate here.

I dont seem to be havining any issues just want to be sure that I am keeping it in the right temp range and for just general purpose... The stove is a non cat stove with re burn tubes...Not sure isf this changes your answer or not

Sounds good. If it's the non-cat, then the catalytic probe would be of no use to you. The other probe I referenced would be what you'll need for double wall pipe

The pipe I have is single wall....Would that probe still work?

Naw, sorry, didn't realize you had single wall stainless pipe.

I wonder if you just use a regular stove pipe thermometer and ran a screw through the center hole? That is, if you don't mind putting a screw in your pipe.

Otherwise, just an IR thermometer should do for surface temps.

375-500 with that IR measured about 1.5 foot up from the stove sounds about perfect.

The doubling the surface temp to get inside temp is really irrelevant. Some say the difference is 1.5, sometimes up to 2x. In all, so long as you are keeping that single wall stove pipe at the temps you are talking about, you are in good shape.

Thanks!!

I think the thermometer pictured also has a spot to run a wire through it so you could actually just wire tie it around the pipe, no holes needed.

The new ones come with a screw, my old one had the wire but that was in case the flue got too hot and the thermometer lost its magnetism.

Curious here,,,if the probe measures the inside temp,,,what difference does it make whether it is single,double, quadrupal, ect, wall?

With a magnetic probe thermometer the coil heats up more from the radiant heat of single wall pipe. The outer layer of double wall acts like a heat shield. There is no bimetal coil in a thermistor probe. I would guess that you could probably use that on either type of pipe as long as the probe is correctly rated for the continuous temps of the flue.

Got it,,that makes sense. Thanks
