Just had the heat running for the first time this season.
The system is a cast iron oil boiler with copper fin and tube baseboard radiators. I haven't really paid much attention to the cycling time of the boiler before, but I'd like to check and see if it is in an acceptable range.
It wasn't all that cold out last night, about 40degF, but enough to run the heat. The boiler was running ON ~2 1/2 minutes and off for 10 minutes. It looked like the thermostat stopped requesting heat as the boiler temp only went up to ~165F before it shut off. (When the water heater runs, it goes all the way up to 195F or so)
I'm guessing that it will start running longer once the outside temp drops.
Does this sound reasonable or should I expect to be calling the boiler svc co?
