Just Curious – Pipe for heating fuel oil tank fill
Quickstep
| Posted in General Discussion on
I’m assuming that copper is not permitted for use for a fuel oil tank fill. Is that true? I’d assume that’s the case because it makes sense not to be soldering around the tank, (eventhough it would likely be empty when the fill was installed). Even so, soldering around the tank could easily be avoided by using a union. I’m curious to know if there are other reasons.

You win the "HUH?" of the week and the first of the new year. Congratulations.
I watched them install a half-mile of TIG-welded black iron in the plant where I used to work -- I don't think soldering is necessarily a limitation.
I know that years ago the lines in residential oil systems used to be copper or brass, but I don't recall how they were terminated/joined.
Keep in mind that for a residential system you only need a line about 1/4" in diameter.
around here fill pipes are black iron as per code and inspected by third qualified party or oil company wont deliver you oil
I ran my old furnace for 1 year on diesel before i put in new furnace & tank what a pita to do
there are 2 ends to this question: the tank fill pipes are galv or black iron w/screw threads and pipe dope - no solder .. the supply to the furnace is usually copper with flare fittings .. again no solder .. call a licenced installer
Around here, oil tank fill and vent pipes are either black iron (interior use) or galvanized (exterior use).
Supply piping from tank to the oil gun is usually soft copper tubing with flare or compression fittings - flare is more common, but I have seen some compression.
In any case, I would hesitate to use copper for the fill pipe just because of the physical strength of the material.
