VA = nameplate if you have it, or breaker x volts x 0.8 if you don't. For PUMPS pick the HP instead — the code table beats the breaker every time. Tick GAS for gas appliances (counts as 0). Tick MOTOR on the biggest motor loads.

Snow melt or other winter-only loads: put them in Heating VA — the calc carries the bigger of winter vs summer per NEC 220.60.
