With a hydronic boiler, what degree setback is efficient for a 7-8 hour period?
Reducing your thermostat setting by one degree.
Reducing your thermostat setting by one degree for eight hours will save about one percent on your heating bill. Focus on Energy recommends not adjusting the temperature more than 5 degrees for daily and nightly setbacks. Greater variances may not save a substantial amount of energy and may create issues with condensation on windows. If your boiler is unable to recover from a five-degree setback in an acceptable amount of time, it may be necessary to reduce the amount of setback.
