Heat Bank Storage and Heat Transfer Information

We will be constructing a modified Thermal Store hot water system. We will use a closed loop solar heating panel and heat exchanger to heat water in a recycled 250 gallon feul tank, then cold main water will be passed through a second heat exchanger in this "thermal battery" before entering the farm's standard electric water heater. In this way the liquid in the solar heating loop, the liquid in the 250 gallon tank, and the potable water being heated all remain isolated from each other.

• Heat Exchanger Information
  • Ehren found a manufacturer that uses 24 sq ft of copper finned tubing ¾” to heat the cold main water. See the more detailed heat exchanger information at the bottom of the manufacturer's page.
