"Class action law suit"

1.0 rating
Very Unsatisfied

I had an old Burnham 86% efficient cast iron boiler. 30 years not one call. Then we added on and needed a bigger boiler. We paid for a Triangle Tube Prestige. It's been 6 years since it was installed. The plumber has been here six or seven times. This is not a poor product. It's a dysfunctional one. Our local wholesalers don't carry them anymore. They don't like to talk about them either because they're afraid of getting sued. On a one to ten scale I give this product a 0.5 rating.

"A Boiler You Can Trust"

5.0 rating
Very Satisfied

We have owned our boiler for two years now and we're very happy with it. Though we rent, we did choose and install this model specifically, based on customer reviews and our own research. It's been a dream to own so far. The best home appliances are the ones you never notice, that stay in the background and don't bother anyone. It's been like this with ours – nothing but two years of constant, reliable service. If there's anything I don't like about the thing, it's the price (which is a little spendy at about $5,000) and the profile, which is kind of oddly-shaped. It's hard to fit it into a traditional space with the squared-off edges. But those are small considerations. No, it's never had to be replaced or repaired, though since the warranty just wore off, I'd expect that soon. I'd absolutely recommend it to a friend who was in the market for one, though most folks might be happier with a traditional furnace instead.

"Piece of junk"

This is the worst ten grand ever spent. Live in Canada, sort of really need heat. Every year there is something wrong with this system. Beyond disappointed. So violently upset by this.



"Go elsewhere"

Bought this pricey boiler in 2012. It started leaking in February 2015. I called the original installer. No answer, never returned my phone calls. I had to call an outside service. They came out and charged me $590 but I couldn't fix the leak. They said Triangle would replace the outside tank but that's it. Estimate to fix it would run about $9,000, so back to square one. Looking to go to another system . Goodbye to Triangle forever.

Purchased Triangle Prestige Excellence boiler. Sorry didn't go on line to review reviews. Most people have had a problem with their products. This unit died in the winter….woke up to a freezing house. The main computer component malfunctioned. Went to replace part…$500.00. Called company….rude personnel. Granted the 1 year warranty had expired…surprised about that…they do not stand by their product. A unit that has to heat your home should last. The last boiler lasted over 20 years with only minor repairs no where near costing $ much for saving on utility costs. I am sorry I replaced my previous boiler… Could have just had it fixed. But because it was very old, decided to get a more efficient boiler. Purchased this one because was wall mountable and did not need a separate hot water tank. However other reviews show they have constantly put money into this unit when reaching five or less years. I hope not. Will have to replace with another unit. Before purchasing something so costly and very much needed, please read all the reviews. Granted, today, it appears everything manufactured turns out to be junk. No longevity to any products. Cost a lot of money, however. Customer service everywhere stinks. The company don't even investigate complaints and improve on the product….BEWARE!
