Reply to comment by KenDurf in Extreme temperature heating by OnePsychological6076

If you have a thermometer put it in the basement and monitor that the temperature doesn’t fall below 45F. Most likely this will not happen as your boiler and the heat piping in the basement will maintain above 45. We generally are not concerned with inside oil tanks gelling because of this. If you had an outside oil tank I’d recommend having a 25-30% kerosene to 70-75% heating oil mixture in your tank to reduce the gelling at extreme low temperatures.

Yup. Some people will put that foam stuff on all the heat piping in the basement to "save energy" but I would only do that near walls or drafts. That piping leaks a little heat to keep the basement somewhat tepid, which is good in the upcoming scenario.
