And they arent, most obviously when a toaster oven is used to heat something small like a pie.

Yes, but all other things arent equal. Its much bigger for
starters and there is a lot more of it to be heated up too.

Nope, The principles are quite different with ovens.

The only way to avoid an oven heating the house in summer is to have a
well insulated oven thats directly vented to the outside and hardly any are.

Its perfectly possible to insulate a small toaster oven as well as a full sized
regular oven and then you will end up with less heat in the house in summer
if only because the wall and door area is smaller with the toaster oven.
