Does anybody make a line voltage thermostat where the contacts open on temp fall. What a customer is looking for is this; they have a fan that blows heat from a wood stove around, but they would like the fan to shut off when the fire goes out. I know this could be done with relays, but I thought some kind of thermostat might be on the market. Thanks
Thats how we do it up in the woods!

Any air conditioning thermostat should do that.

There are many types of line voltage thermostats that have SPDT contacts on them that you could use for this. You need to look in HVAC catalogs or supply houses. Grainger comes to mind as one distributor. They have some but by no means everything that is out there.

Grainger will have something....I recall a job I did long ago at a carwash, we wanted to shut down (and purge the lines) when the temp approached freezing. Can't recall the exact style, type, etc...but they do make 'em.

Is this fan built into the wood stove, or is this an aux fan?
If this is an aux fan, wood burning dealers have this neat fan that just sits on top of the stove, and turns on and moves the air, with no electric hook-up. I don't know how they work, but they are pretty neat.
I have no idea who makes them, but all they dealers around me carry them.

If it is built into the stove, same advise.
Get one from the wood burning dealers, and engineer it into a cover or someplace on the stove.

I don't know how they work, but they are pretty neat. My sister and her hubby purchased one of these units for there stove and ended up returning it. They said the air that it moved was minimal. There are a lot of thermostats made for green houses that will accomplish what you want to do as well although most of them wouldn't look so great in a residential application. http://www.littlegreenhouse.com/accessory/controls.shtml

Dayton controls has a ton of them, reasonably priced. I think the ones I used had a 22A resistive rating. Just pick a cooling or heating/cooling (SPDT) with the temperature differential that you want. They aren't at all aesthetically pleasing though. Ours came from Grainger. We use PSG Accustat units where we want fixed heating/cooling settings away from tampering fingers. They are not what you need here but are available in line voltage units, with up to two stages of heating and/or cooling. Joe
