The parts of oil heat that are not the burner.
Oil heat has logistics gas heat does not. Delivery scheduling matters — running a tank dry pulls sludge and air into the fuel line, which is a classic cause of the "just ran out, now it will not restart" call (the burner needs bleeding and repriming after a run-out). Automatic delivery versus will-call changes how often this happens.
Tank condition is the other half: indoor tanks last decades but still rust from the inside where water condenses; outdoor tanks face freeze-waxing in cold snaps. A burner that starves with oil in the tank is usually telling you about the tank or the line, not the burner — filters clogging every few weeks are the giveaway.
A small but steady share of the market.
These are typically cast-iron oil-fired boilers with pressure-atomizing burners: durable blocks, with faults concentrated at the burner end.
The local pattern is deferred maintenance meeting the coldest nights. A nozzle overdue for replacement, a filter full of tank sludge, electrodes out of gap — each is a consumable, and each fails when the burner works hardest.

Straight answers before you call.
The tank gauge first: close-in oil customers on will-call get caught by cold snaps. Then the reset, pressed once. A repeat lockout with fuel in the tank is a burner fault: nozzle, electrodes, filter, or controls. Call (888) 766-1474 with the gauge reading and the lockout count.
Midwinter lockouts, mostly: the nozzle, filter, and electrodes are the parts that quit on the coldest nights, and the combustion test catches the drift before it becomes a failure. In the close-in neighborhoods where oil persists, skipped service is the most common backstory on a January emergency call.
Inspection first: weeping seams, leg rust, and water in the tank decide the timeline. Then plan the replacement on your schedule, ideally bundled with any boiler work, since the crew and the piping are already there. A basement tank leak is a cleanup, not just a repair; do not wait for it.
Startup smoke means the fuel-air mix is off or the nozzle is dribbling: worn nozzle, wrong air setting, or electrodes out of position. It soots the exchanger with every start and will lock out eventually. It needs a burner service with a combustion test, not a wait-and-see.
Where the gas main reaches your street, yes; in the close-in neighborhoods the mains are generally there, but it is still street-specific. Conversion means gas piping, venting changes, and tank retirement. Call (888) 766-1474 with your street and the triage can tell you whether gas is an option before you plan around it.
