Solar Hot Water

[Les Lazareck]

Please provide instructions on modelling replacing a 75 gallon propane water heater with a solar hot water system that will produce 65% of the needed hot water. The new system will replace the 75 gallon propane tank with an electric 50 or 80 gallon tank (maybe a hybrid heat pump model).

1. Set the Base DHW 1 system to the existing system.
2. Set the % Total for the Improved DHW 1 system to 35%
3. Set the specs for Improved DHW 1 system to those of the new backup system
4. Set the % Total for Improved DHW 2 to 65%.  This should happen automatically
5. Set the Fuel for Improved DHW 2 to Solar.
