Fuel oil (Beckett oil burner) here. It's -20°F outside right now and the house is at 61°F even though I have the thermostat cranked up to 75°F (we have a thermometer in the house as well, that's how I know the temp).
The burner kicks on about every 3 - 4 minutes, runs for a few minutes and shuts off. I'm trying to determine if this sounds problematic or if its expected behavior. And, of course, if its problematic, what the troubleshooting process should look like.
My understanding is that: if the house temp is below the thermostat temp, the burner should be running nonstop/continuously until the house temp comes up to the thermostat temp. Yes/no?!
If this is normal expected behavior, I'm wondering: why? That is, why isn't the burner running continuously until the house comes up to the right temp?!
And if this is not normal/proper behavior, what are some of the reasons for what could be going on here?
