Add the power consumption of all your powerheads, filters, skimmer pump
etc and imagine you have a heater of the same wattage submersed in the
water which is on all the time... This will explain the issue, I hope...
We do not see the temperature increase so much because we do not use
so much water movement devices...
I still use a heater in my 36" tank - during winter months at night,
when lights do not produce heat, powerhead-generated heat is not enough.
