GETTING MORE HOT WATER VACON CHANNEL DISTRIBUTION SALES REGION MAP 37º 42º 47º 52º 57º 62º 67º 72º 35º Determine your ground water temperature from this map. This is the supply water temperature to your water heater. Then, using the table below, determine the potential increased capacity of hot water by incorporating a TankMixer™ on your water heater. For example, in Atlanta, GA, setting the water heater to 160°F, increases capacity by 69%. This equates to 68 gallons for a 40 gallon heater.
