Maximum temperature of wood stove bodies... Does 230C seem quite low?

Take a nail out the fire, glowing orangem that will be at about 850 deg C.

Am sure a lot of us have either had the sides of the stove begin to glow, or heard of it happening, that is at about 650 deg C

Normal operation, outside of the insulating firebricks and cast body, 200 to 300 deg C soubds about right.

The magnetic thermometers are fo the flue - not a part of the stove as such, not insulated and much thinner waled which is why they are hotter

That's right, the brick does keep the hottest temps away from the body of the stove. Not only that, the heat is quickly dissipating off the stove body so it cant stay too hot to begin with. Those magnetic thermometers will slip of the flue with extreme temperatures and it will never slide off the stove body. The flue pipe is thin so it can get hotter than the plate steel of the stove body

Because they lose their magnetism?

 

The Curie temperature for most magnets is 600C and above so the flue pipe would be glowing red before permanent magnetism is lost. Very wasteful of heat to let the flue gases exhaust above 250C.

Just temperory magnetic loss. I'll be going about my business and I hear it drop so I just move it to where it will stick again
