In reply to Michael Walker. I have this corrosion problem, and patched multiple times. Was there ever a class action suit?

In reply to Rich Smith.

We have an Ultra 230 that has corroded through severely at the base of the exhaust column. I have patched this a couple of times, but wonder if this is a basic design flaw.

Other than the corrosion, this boiler has worked great for us… but this problem is severe.

In reply to Sonal Makim. Had the same problem with the heat exchanger. Corroded and started leaking. The new part is also cast aluminum but has been redesigned. This is obviously a design flaw. Would be interested in a class action lawsuit as this is a common problem according to the heating contractor

I am a plumber in N.Y.C and around 3 Years ago I installed a Ultra 80 series boiler in a artist loft down on 23street in Manhattan. This is the third heating season that it is operating and other than a lock-out that required a reset 3 times the boiler has been working fine thank GOD. I recently bought a house and decided to convert from oil to gas and was considering putting in a ultra 80 series which led me to look at reviews about the lock out problems and trying to reset the system which was complicated which was a total turn off to me. I like simplicity. After reading your reviews and I thank you all for posting them. I purchased a slant fin bobcat boiler that’s been running for a few days now. Before buying the bobcat I read good reviews and most importantly slant fin stands behind there product unlike Weil McLean.

Hi there, I am having a new problem with my weil mclain series 2 ultra boiler now. I am getting constant b 19 soft lock outs. Sometimes the soft lock out seems to resolve itself, but generally it is followed by E 19 hard lock out (indicating return water tempature too high.) I verified that that all of the parameter settings are as recommended in the manual. I had adjusted the aquastat setting on the honeywell aquastat on my superstor ultra indirect fired hot water tank. I thought i had set it back to what it was before, but am not sure. I do not see a model number on the honeywell aquastat. It just has a single dial. there is a “pointer” on the dial part that moves, and a similar indicator/pointer on the fixed frame that the dial moves within. I have re-aligned these “pointers”, which is how I believe it was before. It does not seem to have changed the soft/hard lockout 19 problem. The boiler is also “leaking” a fair amount of water from the relief valve. An engineer told me that is because we have such “dirty/rusty” water in my city, and it is normal, so not worth changing the relief valve as it will only start leaking/relieving again. He said it should be doing this… Any suggestions for what I should try/do next? I have a limited support plan on the boiler, so most likely will have to pay if I call to have it serviced. I will call if there is nothing else I can try to adjust first to resolve. thanks for any suggestions you can provide. K

In reply to judy hollingshead. Hi Judy, I have had the exact same problem with my weil mclain series 2 boiler. Even though the boiler was in the basement, you could hear it screaching on the first floor. The boiler was initially installed 4 years ago. I was told that it was not installed properly and was set up to always run on high speed rather than modulate (disabling the high efficiency aspect of the boiler's operation.) So, I paid this company 2K to repipe it. That is when the screaching began. The screaching became higher as the boiler modulated higher - so was very loud last winter. I put fiberglass insulation in the rafters above the boiler and had the piping attached to the wall rather than the ceiling. That did help, but the noise was still annoying. Everyone said there was nothing they could do about it. The screaching has not recurred yet this season, but I am now getting b 19 soft lock outs and E 19 hard lockouts every day. Currently troubleshooting to see if I can resolve without dumpying yet more money in this boiler

I’ve bougth my Weil Mclain Ultra 2 boiler 2 years ago and have had to call for service 4 times. Now the boiler has stopped twice in 2 days and I was able to resstart by removing some water in the condensation hose. I do not have an idea why this is happening. The hose is not clogged.

Thanks for any advice

I have had nothing but 5 years of headaches with this unit. There isn’t a service man with 10 miles that will help me and they all state because fo the poor response from WM and that they won’t honor their warranties or deliver replacement parts timely. At this time I am sitting here with no heat and no hot water because no one is willing to work on this unit, not even WM. I do not have money to replace the unit and cannot get assistance.

As for clearing up your water to help stop the build up, I have Culligan and it doesn’t assisit preventing the corrosion at all.

I WAS TOLD BY W/M REP THAT MY HEAT EXCHANGER HAS BUILT UP RESIDUE FROM HARD WATER. HOW DO I CLEAN IT? AND WHAT PRODUCT CAN I ADD TO WATER INSIDE BOILER TO CLEAN IT?
