Roth Tank Question:

Constantin

Well, count me as a happy customer. No issues with my dual 275 Gallon setup. Both tanks are worked evenly, the Garber filter has yet to show any restriction, and I use B5. I have been using the tanks since early 2005, with B5 since December 2005.

I have heard unhappiness about the Roth pickup tube, i.e. the plastic tube can collapse under the right conditions. For example, one such example was a cold basement, where the oil turned very viscous and the pipe collapsed due to the suction from the oil pump.

Mine are hard piped in Cu, IIRC. Oventrops pickup allegedly is better than Roths, but I have no personal experience. Either way, I see nothing wrong with the tank per se, they certainly are an improvement over the old single-walled approach, much easier to carry in an out of a basement, and the twinning system makes tank farms that much easier to realize.

Roth Tank Question.

Having a problem with 2 Roth 275 tanks in a basement. Both tanks use one fill and vent to the outside. Both tanks have a single line. The problem is that one tank is always being used more than the other. Its gets to the point that one tank will run out of oil. As of today we removed the Roth scution assembly on both tanks and installed copper lines to the bottom with the Roth duplex bushing. Then installed a Tee from both oil lines into one the to burner. I have heard that there is a way to use a 2 pipe system to return the oil back to the tank and equilize the amount of oil in the tanks.

Tanks i feel are poorly designed. that was the best thing you did, by customizing the oil line set up. that tank is nothing but a headache when it comes to servicing. i just don't like the roth tank - bad design. and i'm speaking from experience! Good luck!

You may be Right. Its going to be nothing but problems twinning in two Roth tanks in a basement. With the oil problem we all have it just a matter of time before one oil line from either tank gets clogged and one tank is empty. Then the burner will go out and the oil will have to be pumped over to the empty tank and the line cleared.

what do

you guys think about the top feed only on Roth? I dunno, but I like bottom feeds with the tanks pitched towards the outlet, w/ a big 2A710 hanging there. I have read that due to the plastic inner tank there is less bacteria (read less sludge)..but still. I don't like product sitting still on the bottom of anything, including the chocolate milk you get in the diner:)

IMO, your typical 275 that lasts 25 years plus has a pretty good track record. How long is someone going to make it on a Roth w/o issues?

suction assembly

There are definitely issues if not installed correctly - especially where there is bio fuel used. If you are on the east end of Long Island - that is likely to be a contributing factor.

I've attached the instructions for multiple tank installs. I would review the instructions ...then compare whats in the instructions to what your contractor did. Other than the East End of LI oil issue - these tanks are very sensitive to mis-installation. If you have problems, and he did not follow the instructions - I'd say you have a legitimate gripe. If he's reputable, he'll come back and correct it. They print instructions for a reason.

That said, even though we sell them, I agree with Bob - they are prone to issues - it would not be my first choice.

Roth T.I.T. Tanks

Tony,

Sorry to hear you are having problems with the Roth tank. The Tank in Tank design is far superior to any double wall residential tank available on todays narket. Better warranty too. The tank-in-tank design when installed properly will give you 50+ years of trouble free service, just like they do in Germany. Buy a Roth or a Shuetz, they are both GREAT!

These tanks do not sludge unless you introduce the sludge to them. Meaning you are dumping oil from an old steel tank into them or getting poor oil quality from your supplier. I am sure neither of these two items happened to you but if they did, simply head down to the supply house and pick up an oil bio treatment and presto, no problem. (after you put the correct amount into the tank!)

You will note I said the tanks are the best. The Suction Line Assembly and cross over SUCK. This is the black eye on the Roth tank, or any imported tank. The suction line assembly will increase your suction head by 1-2 INCHES of vacuum. Phew. That said, you will find that the flanged duplex bushings you installed will work great. Simple flare tee in the middle and your pulling from both tanks. Do the same on the return if you wish. Of course I wonder the need to do this. If not for a distance problem I see no need for a dual pipe system. With two pipes you are going to filter 12,000 gallons of oil to deliver 800. You are better off with a Tiger Loop.

Now, about equalization. These tanks, if all lines are purged, will equlaize by reverse syphon. 10 years ago I was skeptical too so the Germans had me do an in home experiment. This experiment will require 2 glasses of your favorite beer, one straw and one 18" piece of clear clean poly-vynal flex tube. Fill both glasses with beer. Fill the poly with beer and invert to go from glass to glass like an upsidedown U. Now put the straw in either glass and drink. I found out it cut my trips to the refrigerator in half! Mmmmmmm.

Have fun and congrats on owning two of the most advanced tanks on the market. Now produced right here in the USA! (watertown, NY)

They are approved for B-10 Biofuel also. Any mix greater then this voids your oil pump warranty. But I know for a fact you can use bio100 in poly tanks without a problem, but they are not approved for this, yet.

Oh, and in case anyone wonders, I do not work for Roth.
