Overview of the Ultra
The Weil-McLain Ultra is an Energy Star rated condensing gas boiler with an AFUE between 92 and 93.3% for regular conditions, and 98% for conditions related to low temperatures. It is a two-stage induced draft boiler that has what Weil-Mclain call "integrated PhD (Precision Hydronic Data) Technology", a system that "initiates efficient and ongoing hydronic heating". The design of the Weil McLain Ultra gas boiler is CSA certified.
Weil-McLain has recalled Ultra Series 80,105,155 and 230 boilers manufactured after June 1, 2012 and prior to March 11, 2014. A cap on the boiler manifold can crack and release gas into the home, presenting a risk of fire or explosion. Consumers may contact Weil-McLain at 888-770-7139 for more information.

"Very energy efficient"
This boiler has saved me nearly 60% of gas usage since replacing my old cast iron boiler. It is very energy efficient and easily will pay for itself in under 10 years of use. I've had it for one complete season and truly love the way the home stays comfortable. The installers did have an early issue with installation, but once re-plumbed it worked without problem.

"Setting the record straight again"
People should read the professional installer's review a bit down below on this page. The Weil McLain Ultra boiler is an exotic piece of technology. When it is installed properly, it is one of the best condensing boilers on the market. Unfortunately, some installers and amateur diy homeowners think that they can just plop down the unit, hook everything up and that's it. Do not buy this unit if you don't have complete faith in your installer.

"In 8 years spent over $8,000.00 fixing a Weil McLean boiler"
Spent over $8,000.00 trying to get my boiler system working. New house built in 2006. Breaks down every 3 months. $300,000 home and I have to heat water on the stove to bathe. I'm a single senior and am going on over a week without heat or hot water. I'm using portable heaters. Told I would have to pay another $600 to replace the heat exchanger that was replaced less than a year ago.

"Bad product, worse extended warranty"
I installed an Ultra 155 in 2004. It did reduce my gas consumption by 20% but it has been nothing but trouble. After a year we had to replace the entire unit. Within the next few years we had to replace the control electronics, the wiring harness and the external temperature sensor (twice), to mention only the bigger problems. I will say that all those repairs were covered under warranty, and the company agreed to provide a no-cost 5-year extended warranty administered by Cornerstone United. They also provide warranties for other companies: avoid them! Two months before that extended warranty expired, the unit began to have ignition failures at intervals of a few weeks. Because they were intermittent, it wasn't clear until shortly after the warranty end date that the problem was and always had been a failure of the unit's ignition system. (First we just tried cleaning.) Cornerstone (should be "Stonewall") refused any coverage, first claiming that the problem was fixed by cleaning and that an entirely new problem with exactly the same symptoms happened to crop up a few weeks later. Then they shifted to a claim that they needed to be notified of the problem before the warranty expiration, though nothing in the document says that. In the end I'm replacing the boiler with one from a different company. I'm tired of worrying, waking up cold, and worrying about my pipes if I go away for the weekend, and I'm tired of fighting about repairs that should be unnecessary in the first place.

"Weil-Mclain Ultra 230"
I just finished installing a Weil-Mclain Ultra 230. After reading some of the reviews, I was a little worried on whether I made the right decision. Reading about recalls and install problems, I was nervous. But going through other boilers, it seemed like every boiler out there had a few bad reviews. While there were bad reviews on the Ultra 230, there were some good ones also and the boiler specs seemed good, so I jumped in and went through with the purchase and the install. My house, I cant remember it ever having heat, and I have lived hear for 30 years. It has old baseboard, single-pane windows, plaster walls with no insulation, and some drafts coming through the doors. With all of these issues, I had my doubts that any boiler I chose would be able to get heat in the house. With all of the issues the house had, the install was a little rocky. One area would get warm, while another area wouldn't. With bleeding the system constantly, modifying the settings, and getting the air and all the kinks out, the house finally had some heat. Since I just installed the system, I do not know what effects this will have on my heating bill, but I am hoping I should see some savings. And as far as the consistency of the boiler and it breaking down, I just installed the system this week, so its too early to tell. But so far I would say that I am satisfied with the boiler. Time will tell if any issues come up. But so far, so good.

"4 years trouble-free does not compensate for 2.5 years of aggravation"
Wein-McLain had always been reliable when I used then in the past on other homes, so when I had to replace my boiler I had a Weil-McLain Ultra 230 installed in 2009. I was looking to lower my gas bills and have a quieter unit. The install was for a 4,700 square-foot home in New York state. The boiler was a problem from the day it was installed, constantly breaking down when it was cold out. I don't think we went without a service call in the winter for 2 years. It had cracked ignitors and flames shooting out that melted the housing. What a P.O.S! Middle of the winter and the house could experience freeze-up damage. The boiler was still under warranty but Weil McLain parts were never available. Then they send via parcel rather than Fed Ex Express because they'd rather save $5 in shipping than protect their customer's home or recognize that a $8,000 boiler install should be problem-free. I had multiple Weil-McLain reps visit and not one of them could solve the problems. At first, they tried to blame installer. Then, failing that, they said it wasn't properly maintained (which is hilarious because the idiot who said that didn't even realize it was a new install). Had a third party look at it and they said the install was perfect, it's just a lemon. I told Weil-McLain that I want a full replacement. They said no. Then I said that they should ship me all the possible parts that could break down for the machine so that I don't have to guess if they'll be available next winter. Again, they said no. I had to threaten legal action and get the rep back again to show them that the housing was melting (again!). Finally, after 2 1/2 years of arguing with me, they sent a replacement for just about every part in the boiler except the frame and combustion chamber. The installer had to spend a full day replacing everything. I don't know if he was ever compensated for that. So now, 4 years later, there hasn't been an incident. But note - I am still afraid to adjust the heat when I travel and I don't trust the thing at all. Yes, the gas bill went down. But my electricity bill went up because of the number and size of circulator pumps. Overall, even though the unit is now working: 1) I don't think I saved any money on a "high efficiency" unit 2) It's surprisingly loud. You can hear the unit kick on and "make the pipes sing" 2 floors up 3) Weil McLain has demonstrated the difference between giving a warranty and truly honoring it. They did little to help avoid property damage and nothing to anticipate future problems or deal with current issues unless pushed. 4) The unit is unreliable and I still don't trust this thing. I go away on vacation and I'm always concerned my house will be frozen solid when I return. Conclusion: Stay away!

"The worst furnace ever"
This is by far the worst furnace I have ever had in all my years of owning a home. It does not heat the house properly. On a cold day(below 20 degrees) the house won't get past 65 degrees. I cannot trust it, it keeps going into lockout and I have to reset it. If I was out of town and it quit on me I would have a big problem. I have had many repair men at the house to try to fix it, but it is still the same. I don't like it and I don't want it. I'm very frustrated with the whole thing. I would never recommend this and I would never buy the same product again.

"Unreliable and expensive to repair"
I have three Ultra 155's running various apartment building and all of them are hassles. All of them have had a motherboard die. Rather than having to replace the problem transistor, you have to pay $400 to replace the whole board. Also just had a blower motor go out. For some reason those are $300. On top of it all, they aren't much more efficient than the 1980's broiler I replaced. Waste of money!

"DO NOT NOT NOT BUY THIS BRAND!!!"
This unsatisfactory review includes extreme dissatisfaction with Heifner Heating in Xenia. It was they who were responsible for recommending and installing this huge mistake and they who told us we would save money on heating. Our old boiler developed a leak in the pump. Nothing wrong with the boiler itself, just the pump. Could have replaced it for about $1100. Instead we were talked into a whole new boiler for more like $7000. Said we would see as much as 40% savings on our gas bill. There has been absolutely NO reduction in our gas *usage* (money cost can't be fairly compared due to price increases) and this boiler has been an absolute piece of undependable JUNK and nothing but a headache. As others have noted, it shuts off and locks out during the coldest weather. "Factory trained techs" come out and work on it and it's fine until the next cold snap, the time you really need your heat. Additionally, we can no longer turn the thermostat down at night because it takes....are you ready for this?....between four and five hours to return the house to the set temperature in the morning. Yep, this incredible piece of crap will raise the temperature in our house by a whopping ONE DEGREE PER HOUR! I have no words that will express how sorry I am that I did not know enough to read reviews before buying. Stay as far away from Weil-McLain as you can!

"Many problems, little help"
Ultra PHD 155 installed in 2002 (I have a box full of replaced parts). We had many problems starting from year one. Both main water pipes broke and leaked water, one year apart. Two blower fans, 3 circuit boards, igniter(s) this I can understand. There are many other parts replaced also. I have maintenance done regularly. Every year I have to have service work done on this system, still error codes continue and usage is disrupted. This was not an inexpensive boiler, it should last and be relatively problem free. I have put more money into fixing this P.O.S than it cost originally. I would not recommend it. My current service company does not recommend Weil-McLain. It's probably time to replace with a quality boiler/company, not Weil-McLain.

"Requires Manual Restarts"
Ultra unreliable boiler, constantly requires manual restarts - sometimes several times a day! Cannot leave unattended in winter or in return I will find my house frozen.

Installed in '05. Generally reliable, then this winter, within 2 weeks it was "red tagged" by the gas company due to a failed gasket. Then the blower died and left us without heat for 24 hours. When technology works, it's wonderful. When it doesn't, it really doesn't. Think very carefully before buying one of these.

We spent thousands of dollars on a new wm boiler and could not be any less happy with it. It shuts down and 'locks out' in the coldest weather and doesn't seem to be fixable. The repairman has been here countless times and even brought a WM area rep once and we still have problems. We were induced to buy by being told we could save up to 40% on our gas bill. After three heating seasons, we have had exactly a big fat zero reduction in our CF usage. Our old boiler wasn't even a problem, just the pump. This was a HUGE mistake. I hate this boiler. I would never, ever recommend buying a WM boiler unless I had a grudge against the person and wanted some really great revenge.

"Ultra is very unreliable"
Installed the Weil-McLain 6 years ago and have never made it more that six months without it quitting. Suspect the electronics have caused most of the problems. However, no one has been able to repair it right. On line help and phone help from the company has been nonexistant. New mother board ordered, five to six hundred more dollars down the drain. If I had the funds, I would start up a national ad campaign against the company and see if that would get their attention.

"Funds R low"
5 years of misery and no heat. Don't care attitude of Mr. Beckett and Weil McLain!! Could write a book. The combo of Weil McLain/beckett or Reillo direct vent does not work for more than six weeks. Total consumer rip off! Many hours of no heat or hot water. After 4.5 years of aggravation and frustration I had a masonry chimney installed. So far system is okay but inefficient and noisy. Something no one has considered, their is red dye in home heating oil. With a direct vent oil system, aside from not performing, the red dye will coat the siding of your home or building. It will not come off! If you happen to see a stainless steel chimney "rusting," It's not rust. It's dye from the oil! Weil McLain and Beckett are more than dishonest in my opinion. Look elsewhere!

"Noisy pump bearing"
Installer had to fix bad factory wiring. Went well after that. After 1 year the red pump bearings sounded like they had sand. Weil-McLain didn't honor but supplier did. 1 yr later is noisy again. Will have to live with it. Gained efficiency, lost the quiet. Would have second thoughts on another purchase of Weil-McLain equipment.

"TIME TO SET THE RECORD STRAIGHT"
I am writing this as a installer/homeowner. I have been in the hvac trade for 23 years. When I started in this trade, the only boiler my boss used was the WEIL-MCLAIN models. I have installed models, ultra, gv, cgs, cgi, cga, heii, wgo, cgx, he, and several other models. The underlying issues with any of these boilers, or any manufactures boilers for that matter, is if they are not properly installed and set up right, they can not - I repeat- they can not run trouble free. Especially the Mod Con Boilers, they need to be installed and serviced by technicians that know what they are doing. I myself have several N.A.T.E. certificates. I would highly suggest homeowners to do their homework before purchasing expensive systems. The benefits of having a highly qualified installer do your installation will pay off bigtime. People need to understand the importance of regularly scheduled maintenance on their hvac equipment. I am not saying that wm boilers have been trouble free, what I am saying is that a lot of problems stem from the installation. People!!!- If it isn't installed right, how can you expect it to run right! My experience has been when I have had issues with wm boilers, I got great response through my distributor and made it right with my homeowners. When buying expensive equipment-take care of it! These comments are coming from an installers standpoint. No other brand is without problems, my advise to mr./mrs. homeowner is do your research on your product and definitely do your research on your installing contractor. I sleep well at night knowing that I have WEIL-McLAIN ULTRA 80 boilers in my own house as well as in all of my rentals.

"Possibly the best boiler I have ever purchased. Reliable, efficient, money saver!"
I have owned my Ultra Series gas boiler for about a year now. What I really like about the boiler is that it is efficient. Well-McLain includes Venturi mixing bodies in this piece of equipment which allows for gas and air to be combined more thoroughly. In times like these, efficiency is important. Another key factor that I like about this boiler is its reliability. No matter what the conditions, this boiler has always been reliable in times of need. What I dislike about the boiler is that the aluminum body dents easily. Thankfully, the dents are easy enough to pop out. If this boiler ever goes bad, which I doubt it will since it has not let me down so far, I would definitely buy the same brand again. If a friend was searching for a boiler, I would highly recommend Well-McLain boilers. They make quality boilers that are becoming more and more efficient.

Bad news. In 5 years, the blower has been replaced, the heat exchanger had to be replaced, and this is the third control board. Good clean power, good clean grounds but the board still goes out every 6 months or so. Putting another new one in Monday but the tech is not sure why they keep going out. The engineer has been out here and yet they cannot figure out why. My advise go with a different brand.

"No weekend tech support!!!!"
My 2 year old boiler (Ultra 155) is refusing to work. So far, 15 man- hours by the plumber who installed it. He can't get a call back from Weil- McLain tech support, and expects not to reach anyone til Monday. (I think it died Thursday night, I discovered the problem Friday night). Manufacturers - do NOT install a computer control if you can't supply 24/7 tech support to the contractors. This is inexcusable. Thank G*d they don't make life support systems.

"Problems since day one"
Purchased 2 Weil-mclain ultras 155 in 2009 and I ve had problems since day one. The first year I had service techs out to my house at least 5 times because water temp sensors kept failing now one of them is having blower issues which also won't allow theboiler to function. Frustrated I called my service tech again and now he won't even return my calls so now it's on to the fly by night guys who charge $125 an hour to stare at my boilers and try to figure out the problem. But at the least I will not ever purchase Weil-mclain again and they wonder why no one buys American anymore where's the pride gone?

We had the Weil-McLean Ultra 155 installed over 5 years ago and are very satisfied with it. However, it is difficult to find qualified service technicians to work on it. As for honoring their warranty, I was very impressed with the customer relations rep that I spoke with.

Do not buy Weil-McLain Ultra Boilers! They do not work and Weil-McLain will not stand behind them. We have had one for 2 years that has not run correctly since it was put in. Weil-Mclain reps were out to look and verified it was installed correctly but it still will not work properly. WM's course of action is to blame the contractor who put it in even though they have already verified that the install was correct.

"Very poor tech support"
Went from oil to gas weil mclain ultra 155 on 08-13-08 and as of todays date 10-09-09 after one year I finaly got the boiler repaired by the field rep. He replaced the so called brain and circuit board. Boiler now runs great.My heating installer had a lot of trouble getting a service rep. to show up. Very bad customer relations.
Other Ultra Reviews
Comments about Weil-McLain gas boilers on HVAC-Talk message boards and heating contractor sites are generally positive:
- In one hvac-talk.com forum, one service tech says that the circulator problem on one Weil McLain furnace is due to a bad motor. Heat is strong in every location except one. This heater is strong and persistent, but the circulator requires attention.
- In another hvac-talk.com forum, another tech observes that the Weil McLain boiler works very well, especially through 3-way valves, and produces considerable heat. A couple of other forum guests agreed with this assessment.
- In yet another hvac-talk.com forum, both techs and guests agree that Weil McLain provides good multiple relay distribution, providing that the circulator and thermostats are up to par.
Weil McLain Ultra boilers come with a 5-year parts and labor warranty. The unit must be registered within 30 days of installation to qualify for the warranty.
