I have my brooder set up with a 250 watt heat lamp. Does good on cold nights but too warm for them during the day. So I initially added a dimmer switch to it but this also required adjusting manually and not forgetting to change it. I had an old electric heater that the heating element shorted out on....so, took it apart and salvaged the thermostat out of it. Bought a plastic outlet box and cover that is used for cable...reamed the hole a little to fit the thermostat shaft through so the knob is on the cover....drilled four holes on each side of the box so it can sense temperatures. Then wired it in series with the dimmer switch. Still want to be able to use the dimmer switch if I want to. So far, it looks like it's working. Will know better in a few days since I plan on making adjustments to it to see how it performs.
By the way, this brooder is outside and it works great otherwise.
