How does the efficiency of a common electric stove burner compare to the efficiency of a common refrigerator?

Question

If I begin with water at a certain temperature, then heat that water in a pan on the stove, then put that water into a refrigerator until it returns to the temperature that I started with, which appliance will probably consume more energy, and by how much?

Answer 1

I agree with answer 1 except for the final line. Heat pumps are more efficient as heat sources than resistance heating when ambient conditions are suitable (i.e., warm outdoor temperatures). (Unfortunately it doesn't work in the other direction, i.e. in refrigeration, due to the work done by the compressor on the refrigerant gas which produces extra heat.) Also, if we take into account the thermal inefficiency of electricity production, even burning fossil fuels or wood for heat is more efficient than resistance heating.

Answer 2

Refrigerator will use more energy Eulal to the same heating energy plus waste. That waste is called entropy. It is really an extra work required by refrigerator components.
That is why the nature receives all the sun energy, but it can not produced same amount of work. Part of it is naturally wasted.
By the way, electric heating is the most efficient type of heat.
