I need a new tank due to rot. Is Roth the way to go?

clydesdale

Hi. The tank will be outside. It will be replacing a leaking 275 that was in a garage. I can't put it back in the garage because code requires concrete posts and I will lose too much garage space. So, is the double walled Roth tank the way to go? Any other suggestions or things I should know about this?

I had a 275 roth w hood installed outside a little over a year ago. Installed a concrete pad instead of lintels. To protect the oil line I installed it in liquid tite conduit from tank to just inside basement wall. The conduit also protects the line from rubbing as it passes through the block wall. No problems w the tank except every so often hand tighten large nuts that hold fill tube, vent tube, etc. I would add a bottle of Hot 4 in 1 before each fill if in a cold climate to prevent gelling and a tiger loop to help warm up incoming oil.

Thanks. Did you use "tiger loop"?

Miata

Yes, I live outside Philadelphia so it isn't super cold but has been down to 9 degrees this winter and the tiger loop w filter plus an extra line loop has warmed the incoming oil.

For the money and work involved a Highland 275 or 550 gallon Petro-hopper would be a better option as it is designed as a steel tank within a tank with a top draw.

I'll be the devils advocate here. I would pour a concrete pad and install a conventional 275 gallon steel tank with bottom draw. I am not a fan of top draw and especially when it is outside. The key is to paint the tank (they only come primed) and put a shed roof over it. It will last for years like this and you won't ever have an issue from the top draw. The tigerloop ultra with the filter should still get mounted at the burner.

How do you paint the inside?

Grallert

Yes get a Roth with a lid or any of the HDPE tanks. Tigerloop and you're all set.

Miata

Rereading the original post has me wondering if .... since the footprint of a Roth is much less than a conventional tank, would there be room in your garage for it w the necessary concrete posts?

@pecmsg To avoid having to use a top draw, I'm ok with the steel tank lasting for over 20 years. Having a poly tank does not outweigh the negatives of a top draw in my eyes.

pecmsg

Nothing wrong with top draw (Like everything else WHEN done right.)

I did the same as @Miata . Roth 1000L on a poured slab. Sleeved a 1/2" coated oil line though 3/4" flexible conduit (Sealtight) to a Tiger Loop Ultra. I add fuel treatment at every delivery. Never a problem except I had to replace the tank gauge last week.
