There is no actual Triangle Tube Prestige boiler series. Instead, the Prestige is a line of three different series.
Triangle Tube Prestige boilers are stainless steel, wall-mount condensing units, and include the Prestige Trimax Solo, which features an efficiency rating of 95% AFUE; the Prestige Trimax Excellence, which features a built-in 14-gallon indirect fired water heater and an efficiency rating of 95% AFUE; and the Prestige Cascade System, which is not a stand-alone boiler but a manifold system which can join 2-5 Prestige boilers.
6 years old, replaced the whole system. After they found it was a transistor on the motherboard, no compensation or reduced price even though it was suppose to be under warranty. Now with the new one, we can't open a window because the exhaust it emits sets off our co2 detectors. Do not buy, run away from this unit and this company.

"They are just Okay"
I am on my 10th winter with two Triangle Tube Solo 110'S. They are definitely fuel efficient but I have had several problems. I am an engineer so I have tried to learn as much as possible about them. Counting the two original blower fans, I am now on my fifth and sixth fan. Three for each unit. The fan blades disintegrate, fall off and lock up causing an error. I noticed last year that the way they plumbed outside effluent and air inlet that the prevailing westerly wind blows the exhaust right to the air inlet. The air inlet is actually higher by a foot than the inlet if you can imagine! This summer I raised the outlet and lowered the inlet so exhaust does not enter the inlet. Another time, one boiler was making a popping sound and would not light properly. A knowledgeable tech came out and raised that water pressure from 12 to 18 psi and everything worked fine after that. Most feed valves keep 12 psi on the unit and he said it was to close to the low pressure shut off. I would have never guessed that water pressure was the problem because the error code showed it was an ignition problem. Since raising the water pressure, I have not had that problem in over 5 year. After coming back from vacation one time, both boilers were had locked out. I turned that if we have a power failure at the exact moment the boilers were trying ignite, they would lock out. In another house I had Weil Mclane boilers and had igniter problems and a blown circuit board. I would agree with other reviewers that hiring an installer that knows what they are doing makes a huge differenct.
"Waste of money."
This boiler was installed one year ago and has required 14 service calls for shutting down. They have added on thousands of dollars worth of crap, by pass valve, mixing valve, two additional air separators, a hydronic heater in the boiler room… It goes on and on. I have supplied the tenant with a space heater and the are using the stove top for hot water to do dishes.
I work on hvac systems for a living in a commercial setting. These boilers, in my opinion, are crap. We have about 10 of these boilers at our facilities round the area. The inducer motors are ridiculously expensive and the wheels on them are plastic and crack and fall apart on every single boiler we have some within 1 year of install and not under warranty. Max temp we run on these is about 180 due to the high efficiency. The control boards in them are to close to the heat exchanger and get way too hot where all the plug connectors get brittle and snap when you touch them — poor engineering. The buttons go crap soon after install and you have to pull board off and clean the surface where the button contacts the control board because it gets oxidized. Overall a horrible engineering design and flaws….basically made cheap by lowest bidder I assume. Great thing is the efficiency. And you may ask why did we keep putting these boilers in, well we were told they were phenomenal in the sense of the boiler and the ss heat exchanger bullet proof, so we bought a bunch of them at the same time and threw them in smaller buildings. All our bigger buildings we run Fulton or PK (Machs). PK Machs are bullet proof so far in commercial setting at 7 years in. As far as residential the best boiler I prefer is Weil McLain. Or any 80%-er basically. They're all built like tanks but the inducers will go out after round 15 years. But, the boiler itself will last 40 if you get spare parts.

We replaced an old oil fired boiler, over 30 years old (which we were not having a problem with except the high cost of oil), with the new gas boiler in 2008. We were told there was a 10-year limited warranty. However, we have found the major parts that run the furnace are only guaranteed one year. The furnace was barely 6 years old and the blower motor went at a cost of $800. Four months later the control panel went at cost of another $800. Do not buy one of these units!
