@KC_Jones anything i can do with this situation? larger near boiler pipes? Or is it close enough with proper near boiler pipes that it would work?

vaporstat

@mattmia2 the unit has an attached honeywell PA404A/B Pressuretrol controller - yet seems like a different language being spoken in how that is to be configured...

The right model vaporstat can be set to control the pressure to keep it under 1 psig or even 1/2 psig.

Thank you for all of the help - the build went great!

You'll get an idea of how it is working regarding the sizing issue…if you find it is cycling a lot during a call for heat, ensure your main venting is good, and minimize any setback (I'd say no more than 3 degrees). Steam works better with minimal setback anyway.

Paul,

While I admit I cheat in several ways, my steam system has no issues with a 10 degree setback.
I'd tend to say as far as efficiency, it probably does better with a large setback than maintaining temperature. But I leave it on 1 temperature because we're all awake / home at different times.
