After some trial and error, I determined that the problem is on the heating side. If I remove "Boiler 2" and only have o

Thanks, sashadf1. Here is a link to "Prototype.CentralAirSourceHeatPump.rb".

Thanks, sashadf1. I just edited my question above to include a link to that openstudio-standards file.

I have a boiler with two stages that has no gas rate modulation besides off and those two stages. What is the proper method to model this? Is the appropriate setting "SequentialLoad" for the Load Distribution Scheme at the "Supply Equipment / Demand Equipment" boundary? I tried that and "Optimal", but got the same water heating energy usage results either way.

I'm trying to set Site:WaterMainsTemperature within OpenStudio, but nothing I do is impacting the results (e.g. water heater energy usage is unchanged). I see in DView that Water Heater Use Side Inlet Temperature is wrong (i.e. the temperature spikes over the year), but don't know why. Please see my OpenStudio 2.4.0 screenshots.

Update: I experimented with my model, but still got water temperatures that don't make sense. Here is what I tried (and which is not shown in the screenshots):

1. Removed the Set Site Water Mains Temperature measure.
2. Copied the osm file with a new name so as to ignore the associated file folder in hopes of removing unknown issues.
3. Removed the bypass pipe.
4. Changed the pump power to something very low (1 W). Plotted Pump Fluid Heat Gain Rate which is low as desired and expected.
5. Plotted the Water Use Connections Cold Water Temperature, which shows the proper default temperature of 50 F. However, Water Heater Use Side Inlet Temperature is 135 F which doesn't make sense.

Problem solved. The culprit was the adiabatic pipe directly upstream of each water use connection. Once I deleted all of
