My refrigerator has 200w of draw and most of that goes into doing the refrigeration, so a few dozen watts of waste heat is my estimate based on my refrigerator. Which isn’t a big refrigerator, it’s definitely on the small size. A bigger refrigerator with a more powerful compressor will produce more waste heat but it’ll still be small compared to the energy put in to do the work. And it’ll be tiny compared to the wattage of a heater which top out at 1500 watts.
That’s not quite how refrigerations works. The energy doesn’t “go into” doing the refrigeration; the energy you’re bringing in from the electrical grid is still in your home.
In other words, if your fridge runs at 200 W, then your home is being heated at 200 W, plus whatever heat is being pulled from the inside of the fridge.

Oh, I see what you’re saying!
