"Lousy product"
This system fails every few months and we have to get a contractor to come and try to fix it. At first we thought it was the contractors, but it's clear it's the product at this point. It reminds me of some cars from the 1970's and 80's -- it was a good day when it started up in the morning. Every few months we just don't get any heat, we call for service, we spend several hundred dollars and a few months down the road, no heat and we call for service, and we spend several hundred more dollars. I will never buy another Weil-McLain product again, that's for sure.

"Weil McLain Boiler"
Just wanted to say that Weil McLain is great. Website has great options for narrowing your search, and they even locate local distributors who have the product and come out and install. I love that! I choose the CGa Gas Boiler Series 2, the pricing was compatible and they have a very reasonable return policy. Spoke with someone from customer service on the phone to ask some detailed question about the model I was interested in getting. They answered all my questions and were very friendly and I didn't feel rushed. After ordering the model I wanted they sent out two installers who had great knowledge of the equipment. The installation was fast and they cleaned up not leaving even a piece of paper behind. I would highly recommend Weil McLain to anyone. They are extremely professional and will do anything to get you what you need. Thank you for the great experience so far.

"Efficient, low-profile boiler"
I am very satisfied with this product from Weil McLain. This boiler was able to fit in a space that we had originally thought would need to be rebuilt. We got this boiler specifically because of its size and ease of installation. I have had it in use for about a year with few issues. The best aspects are the size, installation, and the controls that are super easy to get to. My only issue was a break in the steel insulation jacket about 2-3 months after installation that resulted in some heat loss/ inefficient heating. Luckily it was a quick fix and not too expensive at all, and the support at Weil McLain was super helpful. This boiler lasted through a rough winter here in Massachusetts when I've heard of many others that failed. I would buy this product again and I would recommend it to a friend in a heartbeat. I am not looking to replace it at all.

"This boiler is great, very easy to use, it is extreme efficient. Installation was easy"
- The boiler is 2 years old. - It is ready to use whenever you need it, the temperature control is easy to use. - It does take up a lot of space. - I have not needed to replace it yet. - It is very trustworthy and reliable.

"My 70,000 BTU'S WEIL McLAIN CGA3 Gas Boiler"
I've owned this boiler for about two months. It came with my home. I like the fact that it provides me with heat unabridged. Never do I actually think of my boiler, which means it is doing its job correctly. I can put whatever "tax" on the system that I need to without fear of damaging it, or it not being able to keep up. I have never had to repair or replace it yet. I would definitely recommend this brand, and specifically this model to a friend. I've gone through about three boilers in my lifetime. Although I've only got to see this one in action for two months, it seems to be the solidest build, and its specs, and ratings are much higher than any other system that I've had the pleasure of owning(not to mention, It works the best too, and has the lowest maintenance). I give it a ten out of ten for certain. If I had to buy another boiler, I wouldn't think twice(unless this one broke, but I very much doubt that will happen).

"Do not buy this brand."
We had this boiler installed on 2/17/15 and we had to call the plumber who installed it 4 times already. They are coming back tomorrow to replace it. This boiler does not provide adequate heating for our home. The plumber told us that they guarantee a temperature of 75 degrees when the outside temperature is below 15 degrees. Needless to say that, despite an outside temperature of 20 degrees, our inside temperature is only 64. We should have read these online reviews before installing this lemon of a boiler in our home.

"Weil Mclain Rocks"
I have had this boiler for 5 years now. I really enjoy the compact size and easy installation. There really is nothing bad to say about this boiler the price was reasonable and again the size is awesome I was replacing a much older unit that was taking up space and making a lot of noise this boiler is perfect for quiet heat. I never had to repair this boiler and hope I never will! I would reccomend this to anyone thinking of upgrading their old boiler, they will not regret it.

"Stay away From Weil-McLain"
We replaced a highly functional boiler with this 10 years ago and have had nothing but trouble. Our installation company has been awesome at attempting to resolve a horrible boiler, at best. The latest issue is a loud banging. The manufacturer says to use muriatic acid to clean the boiler; this won't burn holes in the copper! There is non-existent customer support or concern. They are most unhelpful in resolving problems with their product. The sensors have been replaced and the pumps have been replaced. Stay away from this manufacturer unless problems with heat are what you desire.

"What a lemon"
Revised review, changed the purchase date from 2014 to 2004. I had a Weil- McLain boiler installed in August of 2004. After 9 years it developed a pounding noise that no one could correct. There was zero support from Weil-McLain after many telephone calls that fell on deaf ears. I finally scrapped it out. I just installed a new Peerless boiler. Should have better luck, I hope. I would never buy another Weil-McLain product or recommend one to anyone.

"Good so far"
I installed this boiler myself in 2000 and have not had any major trouble. I have had to replace 2 relief valves that began leaking over the years but that's not the boilers fault. I also used poly-propelene glycol at a 30% solution because a have a unit heater in the garage. I also use it for heating my domestic water which means the boiler runs year around.

Review:
"1982 models were great"
I bought and installed a CGa5 in 1982 with electronic ignition and vent damper. I had a failure of the Johnson Control module for the electronic igniter in 1984. Since then, it's been flawless in a 90 year old home with large cast iron radiators (2 zones). This unit has never leaked a drop. I clean it every year, remove, inspect, and vacuum the gas feeder tubes, vacuum the floor of the boiler, lube the stack damper hinges, lube the two old style Taco circulators, and it's good to go. It's 31+ years old. I think it needs replacement based on age alone. But I'm afraid of these new ultra efficient boilers, they seem so error prone. What to do??

"Biggest Piece of Junk There Is"
I have had this thing for 11 years and I have not had 1 year that it has not broken down at lease once a year. Most of the time, it is two to three times a year. I called the company and they were rude and hung up on me, so I send them a letter and they never answer back. I would never buy from them again.

"Worst Company Weil - McLain, stay away"
I bought these Weil McLain 2 years ago. In less than 3 years, it started to leak from the heat exchanger. I called the company for the warranty but they refused to give it. We argued and they asked me to ship the boiler to their manufacturer in the United States of America to diagnose the problem and after checking they will let me know if it is still covered or not. I got a quote for shipping from them and it is almost $700. Again, they did not give me a guarantee if they will replace it or repair it. It took me over 20 emails to reply, and after all they refused to cover the warranty on it.

"Cracked case, refused warranty at 2 years old!"
Boiler is 2 years old, the cast iron assembly cracked (which is stated to have a lifetime warranty). They refused warranty so I had it welded, cracked again in another spot the next winter. Now they say they will warranty it if I pay shipping on the old unit back to them, then wait 3-5 weeks for the replacement! Stay away, they are junk!

"4 years old 3rd heat exchanger put in yesterday 12/01/11"
This hot water boiler works great then it starts leaking. Weil McClain warranty stinks they have not stood behind equipment at all. It's always my fault and that's that. This is their last chance and I am going elsewhere forever. 3 cracked sections in 4 years not good.

"Nothing but trouble with Weil-McClain"
We were told by the heating-plumber company that this was a top-of-the-line furnace, and that people almost never had any problems. However, this has not been our experience. The parts malfunctioned as soon as the warranty expired. We had to replace the expansion tank and diaphragm, the Pressure-reducing valve, and also the pressure-relief valve. One month later, the furnace is making loud popping noises every 5 minutes. What a ripoff! Do not buy this furnace.

Other CGa Gas Boiler Reviews

While contractors note the CGa is a simple unit typically requiring relatively inexpensive maintenance, there are few other positive reviews regarding the CGa. Homeowner forums such as justanswer.com and gardenweb.com detail several issues with the unit. Complaints include intermittent water heating, failing components, and trouble getting the system to start and heat properly.

In addition, several contractors recommended other brands to shoppers over Weil-Mclain, saying they will get more quality and performance for their money with alternate HVAC units.

Consumer reviews on greenoptions.com and gardebweb.com also reflect negatively on Weil-Mclain as a company, stating the company has minimal support for existing customers and is slow to respond to inquiries.
