Hi I have an enclosure with an electrical heater that runs on 5W. Im trying to figuring out how warm the enclosure gets after a set amount of time. I need help with the strategy on how to tacle this problem. The heater warms up the air inside the enclosure (Specific heat) then the enclosure absorbs some of that heat and then radiate that to the outside depending on the sun radiation and ambient temperature. I have been stuck on this for 2 days and I really could use some help confirming or helping me along the way on figuring out what I need to solve it.
