I want to run the heater on 120v ac. So if i'm doing this wrong please let me know, or if you know of a more efficient way to heat the incubator please let me know. The incubator is basically 8 cu/ft area heated.

I propose to use 10@ 18ohm 10w ceramic resistors.

(I want to use 10w cause there cheap and easy to get.)

18 x 10 = 180 ohms

115/180 = 0.64 amps

0.64a x 115v = 73.6 watts

73.6/10 =7.36 amp each resistor which is less than 75% of the max

I was also wondering about a spray head spraying the heater to raise the humidity in the incubator.
