I am not going to comment because I am in rare form at the moment, but just want to say cool beans in the knock up
@Sally Sunshine -- Lockdown is Wed Feb 10th (before bed)
gotcha!!! thank you!!!
There is air movement and it sits on a heat sink. It's just supplemental heat to remove the temp gradient I was seeing because the incubator is so deep (48 instead of 30 inches, so I can fit 6 trays instead of 3).
The PTC heaters with fins are made for sitting in a stream of air, but the flat plate ones are made to heat surfaces. This is the type of heater in auto seat warmers for ex, where all the heat is transferred without air flow.
Then it should work great for you!
