Hello

I would like to see how much heat the brand of wood pellets is putting out.
What is a good thermometer to get and how much does it cost?

Also wher is the best place to put it?

I have an Avalon Astoria with the 3 sided glass front and 10 round heat exchanger tubes.

Do you mean a thermometer, or thermostat?

Easiest thing is to get a magnetic one from a stove store, it's great as a comparative tool for pellets. If you're looking for absolutes you'll need a sensor and gauge or I/R gun or similar. I have a magnetic one and it allows me to compare brand A to brand B easily by mounting it on the hottest exterior surface and glancing at the results. If you want to determine how hot the the fire is, that's another thing altogether.

Hi

Thanks Canada Clinker, I bought a Rutland Magnetic Stove Thermometer at the hardware store last night. Thanks Nectardan, it is just like the one in your link.

However Canada Clinker, just like you, I wish I had something more accurate. BTW the link to JC Whitney Page says it is no longer there.

I do have a small digital Radio Shack hand held IR Thermometer to measure the air coming out but it is much better to have a thermocoupler in the heat exchanger tube like you do!

Please let me know if I can buy something similar to what you have on the internet somewhere. The accuracy would be really helpful in making the auger rate setting adjustments and also help with the Brand of pellets I buy!!

There re lots of choices for temps .....from IR guns, meat thermometers, fluke meters with thermocouples, styles, calibrations, etc. Important thing is to be sure what ever you decide to buy is kept at the same spot, depth,length of timeat heat load, etc. Repeatability is important. Many variables are involved, try to keep them at a minimum. Try to write your findings down and keep them in a safe spot for reference.

Magnetic stove thermometers are notoriously inaccurate and they give a surface temperature reading only. Not much good when trying to asses air temp output. I had one on a wood stove that read 125F when the stove was cold. IR thermometers are very accurate but only read radiant temp and must be perpendicular to the surface for best results. Again not great for air temps. A very good low cost option is a digital oven thermometer. Just take your reading from the same area of the stove every time.

How about a el cheapo oven thermometer from Wal-Mart for $5.99. All you have to do is bend the bottom edges to fit the convection blower output on the front of your stove and you're ready to go. Not laboratory accurate but it gives you fairly good idea of what your stove is doing.

Hi Don, that's a neat looking digital thermometer and would work great by the looks. I prefer low tech stuff for applications like a pellet stove, the less complicated it is, the less that can go wrong. If it goes bad, I just drive over to Wal-Mart and buy another one for $5.99 and no batteries required. The money I save can go for pellets and beer as some of the more well known forum members will recommend!----Lorne.

This is what I use on a daily basis. I just changed over today from Maine Woods pellets to Greene Team. After watching the auger swallow the last of the Maine Woods I threw in the Greene Team and with no other changes to the unit saw a 5+ degree difference between pellets. It's made by Cooper Atkins.


The Maine Woods were running 111.3 to 117.5 degrees on heat setting #3

The Greene Team are running 120.2 to 123.8 degrees on heat setting #3

Hello

Thanks for the example. It seems like an accurate digital is the best way to compare pellet brands. I was testing Maine Woods Pellets and I thought they did not burn as hot as the nice Logik-e pellets that I am running out of!!

Is this similar to what you have for approx $23?
http://www.coleparmer.com/catalog/product_view.asp?sku=9000061

Do you stick the probe in all the way and leave it there for a while?

Don
 
.......here's the 'remote' thermometers I spoke of earlier.(someone mentioned a link wasn't working).... Thermometer 1 and Thermometer 2 ........I'm using 'Thermometer 1' with my 'remote' receiver displaying 214F air output temp ....unit about 15 ft away from the stove beside favorite chair and with stove percolating on Low ...... again my setup looks like pics below.....(click on pics to enlarge)....... cc :)

I leave mine in all the time and turn it on every so often to see what the temp is compared to the heat setting and such and then shut it back off.

any suggestions as to where to locate the probe on englander 25 pdv.i have been playing around with it for an hour or so and getting various readings.the 5 holes over the door on the front of the unit blow the air out.should i just insert in those holes or hold it on the outside.

Cheap probe type digital meat thermometer from Ikea, probe bag-tied to the middle of the hot air outlet. I had to cut the wires to the alarm because it kept resetting the alarm temp and going off, but otherwise works great. Display has a magnet which sticks to the front of the stove, and the original battery has lasted over a year. It was about $7, picked up on a trip to the big city.

......hey Don....... nice find!! :) ........ for fun, you could set it up to see how the left side of your stove compares to the right side ...... or you could put one in your stove and another one in a turkey and keep an eye on both at the same time!! ....... or here's one...... monitor the air temp 'before' it goes into the exchanger of your stove and monitor it when it leaves the exchanger into the room, to see how much heat is 'added' to the air with a particular pellet burning..... neat!!! .......lots of possibilities...... now I'm sure you will be checking back with us regularly with ur testing results........... cc :lol:
