Tube heater

[Twostage]

I've done the same as you, and got a 60W 1ft tube heater in my fermentation fridge. First brew with it has been successful - a best bitter fermenting at a steady 18 C. I was also hoping to get it up into the 30s to do kveik. I wonder if there is any way to override the cut-out... (or is this just asking to burn down the garage...?)

Don't know how you are measuring/controlling temp but you could stick a temp probe on the body of the tube and implement your own cutout. The silver DS18B20s I use work up to 120c which gives you another 30c.

With no thermal cutout I imagine they might get a bit toasty.

(There's no thermal cutout on a 40w bulb )

Absolutely agree, but if that's not your bag, add whatever you like

I've had brews constant mid to high 20s with a tube heater according to the temp probe which was placed behind a chunk of HD foam taped to the fv.
I put the fv in the fridge at 25c plus and set the inkbird to control at about 25c. I've done only a couple at these temps,one a kviek and a wheat which I wanted to see what happened. During peak fermentation when it's generating heat the inky was up to 28.

Maybe its better at conducting heat.

Maybe its better at conducting heat.

With a given conduction coefficient, from fv to sensor. Decreasing heat conducton from sensor location to surroundings, using HD foam etc, will improve sensor reading accuracy.
