They aren't that great as you will get a totally different temp dependent on surface colour/texture - I know I have one! If you have say a shiny SS flue with black spots on it shifting the red dot from one to the other sees a marked difference.
Umm that's because it is a different temperature dickymint said:

Umm that's because it is a different temperature Lets make a test; My living room table, ambient 20'c. Two items sat on there for four hours now; piece of matt black paper, sheet of shiny Stainless steel. Put the IR dot on them and they will read different temps, they both should be 20'c but aren't, why?

According to this there is an emissivity adjustment on the device. The device should be used on objects for which you know the correct emissivity setting. You can determine this with a contact temperature device. You can't just switch between low and high emissivity surfaces.

But you do have to run them at a level that keeps the stove and flue in an optimal temperature range for good performance, no?
For a 26kW stove this is going to involve more effort (and produce more heat) than a 3kW stove.
Very interested to read about how much legwork is involved with keeping it at the minimal good burning temperature.
Not found that myself (I have a good quality 16Kw woodburner). I can get it to run well at quite low outputs.For a 26kW stove this is going to involve more effort (and produce more heat) than a 3kW stove.

That's an interesting concept. If we say that a good operating temperature is 200C, then a big stove at 200C is producing more heat than a small stove at 200C... yet both are the same temperature....For a 26kW stove this is going to involve more effort (and produce more heat) than a 3kW stove.

I suppose it's because the surface area is bigger
