[Equest-users] Pilotless DW Heaters

As per this article, heaters without pilot should give more savings (ofcourse duh! to me). I am not sure if changing the curve also removes the "extra" energy that pilot needs.

Subject: [Equest-users] Pilotless DW Heaters

I have a project which includes pilotless DW Heaters.  I used the "DW-Gas-Pilotless-HIR-fPLR" performance curve in order to mimic this but the savings compared to the standard curve are higher than I would have expected.  Does anyone have experience using this curve or know the basis of where/how eQUEST developed it?

Note-I'm using the energy model to calculate savings for LEED EAc1 and have received some pushback relating to that curve.

Thanks,
