[Equest-users] Preheat Coil Energy Use

[Robby Oylear]

John,

With a system with heating-type = FURNACE, I add a pre-heat coil of type =
FURNACE and the total heating energy use drops from 900 MBTU to 50 MBTU, yet
there are no unmet load hours.

I don't see how the system could be meeting the loads yet using no energy.
 If I look at the SS-B report there is a fractional use of energy for
preheat.
