What else costs about the same in Michigan
Cutting the number down
- A good cover is the whole ballgame. Most of the energy replaces heat lost from the surface, not heat delivered to people.
- Holding temperature usually beats cooling down and reheating, because reheating a large mass of water is expensive.
- A waterlogged cover has lost its insulation value and quietly doubles the standing loss.
