The largest expense related to hot water is maintaining the water at a constant elevated temperature over time. If your hot water heater is more than five years old, install a 3 inch water heater insulation blanket. If you choose to purchase a conventional water heater, select the smallest tank that will meet your needs. Tankless hot water heaters are quite appropriate for many applications in churches, where the primary uses are for washing hands and, less frequently, dishes. Return to Checklist Refrigeration 1.
Refrigeration is one of the most expensive uses of energy.
Again, make sure you use just what you need. Before you accept or purchase a new refrigerator, consider whether you can really afford to pay the extra energy costs. Unplug and remove refrigerators you don't need. If you occasionally need more refrigerator space for a dinner or other function, plug in the extra refrigerator only at that time. Lock unused refrigerators so children don't play in them.
