Avg. BTU Rating for Appliances (Microwaves, Refrigerators, Etc.)

the sizes and ratings are so varied, I have given up trying to guesstimate one. The fridge duties (compressor ratings) dont help because the motor may only run for a fraction ofthe hour.
I could only estimate the gain by determining the physical external area, then use a typical internal-external temp difference multiplied by the thermal transmittance value.
It wouldn't be much I guess, perhaps 20W/m2 of fridge area for internal at -20 c and room at 20C.
so for fridge at 2m high x 0.6x0.6 (we have small fridges in the UK) then =96Watts (excludes allowance for compressor COP etc) I would allow something like 150Watts to be on the safe side.
