The WORST customer service and non-existent after sales support
bawa reviewed December 11, 2008 at 6:11 pm

My 3 year old Ultra 105 just catastrophically failed after three years in service, with a cracked heat exchanger.  Weil-McLain does not have the part anywhere, including at their facility, so now I am stuck with no heat and no hot water in the middle of a Minnesota winter for 6+ days while I wait for their factory to MAKE the part and then ship it to me at my expense.  And If I'm lucky, I might get reimbursed the ~$2000 part under warranty.

 

Getting anyone at Weil-McLain to return a phone call or provide assistance with expediting this repair has  been impossible, even though there are two of this same model boiler at their distributor here in Minnesota that they could have swapped for ours or gotten the part from.  Needless to say, this is extremely frustrating for a product that was sold to me as high-end from a supposedly reputable, American company.  And what good is a 15 year warranty when it's impossible to get any service?  This is seriously one of the single most dismal, disgusting customer service events I've ever experienced.  Buying a product from this company was a HUGE MISTAKE, and I certainly hope this is the last of the issues with this boiler during it's lifespan.  Needless to say, I would never consider buying another Weil-McLain product, ever.

Service is Astoundingly Poor
Cwaggy1 reviewed November 19, 2008 at 8:19 am

I had called WM for warranty service on a Saturday and it is now Wedesday and I am without heat for a 5th straight day. The local service people were not trained by WM to recognize the difference between a fault in the main boiler control vs. the digital face plate.   When they installed the new main board, the same fault error showed up and after calling tech support the local service people determined the digital panel had failed (there is a control point 'chip' in the read-out panel) and they were to return with the right part.  Well after learning that not a SINGLE WM supplier in Massachusetts had the part, it is apparently running one down from VT fedex.  Still, no heat.  This is the 2nd time an electronic failure has caused a boiler failure of this nature.  I am going to demand an extended warranty.  They should offer an lifetime warranty on all the electronics since there are no 'maintenance' obligations the owner has to maintain them under the obligations of warranty.  Had I known it would take the better part of a week to repair this boiler I would have bought a Munchkin or a Burnham.

Weil-McLain Ultra Boiler
boilernut reviewed April 28, 2010 at 6:03 am
I have owned my own service company for nearly 30 years. I have been on numerous calls for multiple manufacturers of boilers.  They all have one thing in common. If they are not installed properly, they will have issues.  The new technology associated with a high effeciency products requires that the installer have a deep understanding of how heating systems truly work. Too many people are quick tp blame the product for system or installation issues. I have a Weil-McLain ultra boiler in my house and it never skips a beat.  I clean and service it yearly and it is installed exactly per specifications. There a 5 supply houses within easy driving distance of my shop that carry both parts and product.  Something about this review does not seem right.  I can call my Weil-McLain rep and he gets back to me within hours and he has certainly never lied to me.  They are the most reputable company I have ever dealt with and that is the reason I have installed their products, problem free, for over 30 years.  If I were you and are still having problems, I would consider a new contractor, new distributor or both.  Just my .02

Weil McLain 230 Boiler
cfbloom reviewed January 27, 2009 at 9:11 pm

After reading the negative rewiew about the Weil McLain boiler, I just had to respond with my own experience.  Our original hydronic system from Heatway Systems (bankrupt due to tubing failure-manufactured by Goodrich- also out of business) was powered by a Valiant boiler a little over 20 years old.  I know way more than I wanted to about under floor hydronic heating since I have installed "Twintran" tubing that ultimately failed and led to the premature failure of the Valiant boiler.  I've replaced the tubing with Onix and now the boiler with a Weil McLain and pretty much rebuilt the hydronic distribution panel and manifolds.

 

I am fortunate to know a certified HVAC installer, and when the Valiant was generating too much CO, they detected it, and shut it down immediately.  We went through all the options about boiler replacement (and possible repair of the existing boiler) and considered 1/2 dozen different models from cheap to higher price efficient models and ended up selecting the Weil McLain Ultra 230.  These folks have installed dozens of these boilers and recommend them because they don't have any recalls.

We spent a week of sub freezing and sub zero temperatures continually feeding the wood stove, but I know the three days waiting for the boiler and 2 1/2 day installation was worth every cold penny.  Carr's came back 2 days later to make sure all systems were functioning properly which they are.

The boiler, system, and installation were well thought out and planned.  The bottom line is that the quality of the installation is more important than boiler selection.  I can't wait to see my first gas bill.  The meter is "squeaky" and I know it's running at less than half the pace it was with the old boiler.
