Kevin:
 
Ht. Pump Supplemental is exactly what you perceive. Add electric energy
to maintain heat pump heating when the loop or air unit itself cannot
hold load.
 
The below charts you include have peak scales of 100,000 kWh electric
and 200 million Btu gas.

Folks,

I have a basic question about the results page on the consumptions and
headings.

Under headings:  HP Supp.  What is this showing?  Is it supplemental
heat pump energy?  

 

What are the multiplying factors for kWh and Btu?  Am I supposed to
multiply the kWh by 1,000 or 100?

Am I supposed to multiply the Btu by 1 Million or 100,000?

 

I'm used to single family home modeling, so I do not have an idea of the
range of consumption I should be looking at.

Thanks,
