[EnergyPlus_Support] Re: question about html report

["Herve B" <brouchery.herve@xxxxxxxxxxxxxxxx>]

Yes, I agree with you.
So the report should provide:
WATER HEATER USE ENERGY >= TOTAL WATER HEATING COIL ENERGY.

But in my case this is the opposite:
WATER HEATER USE ENERGY < TOTAL WATER HEATING COIL ENERGY

Why??
