I'm still using the one that came with the stove and I would like to get one that has a range.  Say like 160-170.  Are they a pain to
install?  I have seen alot of different ones being used but I dont know what to get.  Dont think I want the strap on kind but the
submersible ones I think you have to make some kind of well?  I just dont know.......

I am using a simple Ranco temp controller with single no/nc contacts. It was easy to set up and fairly cheap I think $70.00 at a big industrial supply house. You can set a range up to 30 deg if recall correctly. I run my device at 180 with a 10 deg range so it opens my damper and starts my fan when water temp gets to 170. The well was about 35 bucks at the same supply house I am tighter than 2 coats of paint so I soldered a piece of 3/8 copper tubing to my incoming pipe and slid the probe in it then covered the whole thing with insulation worked nicely. Good luck.

As for the well .  drill a hole about 14" back on the top of the furnace.  One guy just used a 12" piece of copper tube with a cap sodered on the end . At the top you can use a reducer or just flare the end so when you drop it in the hole the reducer will catch it.then drop in the probe from the ranco and put a little silicone around the hole to seal it up and your done.
