Staging tank ... save energy cost ... preheat cold water

Staging tank solves problem with cold water

During winter, staging tank inside basement or crawlspace warms cold water using ground temperature see groundwater temp map

Use old water heater or buy scratch-n-dent 20-30 gallon water heater for staging tank. Do not connect electricity. Insulate pipes.

Net energy gain when staging tank heats from natural ground warmth or heat-pump exchanger or sun exposure

Copper tubing can also be used to make water reservoir. Copper lasts longer than steel tank <> 320 feet of 3/4" tube = 20 gallon
