Re: Tweaks for a new heating system
Sounds like your doing pretty good. IF the boiler is properly sized and isntalled it will run most effciently. Sounds off hand like a knowledgeable installer. 4-5F setback is the most you want to run for a properly sized system. If you want deeper setbacks, you'll need a supplemental heating source like a direct vent fireplace or some radiant floor heating loops.
Honestly, I find my wife won't tolerate more than a 5F setbakc anyway. Jsut gets too cold for her at night.
SOunds like your in pretty good shape.
Did the service tech run a combustion analysis to make sure it was firing effeciently?
It might be possible to tweak the outdoor rest setpoints a little. But if this sinstaller does a lot of boilers, then he probably knows the best temperature for your area.
Enjoy you nice even radiant heat. Funny how folks act like it's a new thing on the latest and greatest custom modern homes. The Romans 2000 years ago knew radiant floor heat was one of the best ways to heat a structure. The romans also used 100% renewable biomass energy... wood. We think we're so clever and advanced sometimes.
