Pull Request Description

Closes #1858. When instantaneous water heaters have greater than 3 gallon tanks, they will be modeled as conventional storage water heaters. When tank sizes are <= 3 gallons, tank losses will be ignored as before. AHRI shows all instantaneous water heaters are either <= 3 gallons or >= 20 gallons.

  • Renames "tankless" to "instantaneous" in code and sample files
  • Allow TankVolume input
  • Allow HeatingCapacity input
  • Change PerformanceAdjustment default
