any thoughts on the nti thermal trinity condensing boiler

Garett_2 Member Posts: 3

Any thoughts on the Trinity Ti condensing wall hung boiler made by NTI Thermal. Are they reliable and durable and easy to service, aware of any problems would appreciate the input. The reason I'm considering is that it is the most economical boiler on the market in Canada that I'm aware of, let me know if I'm wrong. Yes I hear the Triangle Tube prestige is better but a lot more money too.


For any feedback

    Good value

    I've had good results with them; new radiant concrete, fin-tube retrofit, and panel radiator retrofit. 25-50% reduction in gas usage. They share the Gionnani made heat exchanger with several other mod-con brands; the piping and pumping is important - considerable head. Easy to wire and program.

    Parts availability

    We had a customer who installed the NTI on a regular basis and was a factory authorized service agent. He stopped selling them because of parts availability. He now sells/installs the Prestige.

    You may want to take a close look at this. No matter what you paid, if a part in your unit fails - can you get parts for service? The gas valve, sensors, fan, transformer, logic board, etc. Are they readily available? Does your local supply house carry parts? Do they have a unit on display that they could steal a part from to get you heat? It was an issue - perhaps not any more - still worth looking into.

    Triangle Tube, (manufacturer of the Prestige)is located in NJ. This is where they are made. There should be no issue getting a part UPS out of there. In addition, they make an attache case part kit that alot of our installers have purhcased. They keep it on hand,in the shop/truck so in the event of a call, they should be able to handle it. Besides our display, we usually keep 2 parts kits in stock. Some of the higher end jobs, we supply the kit and keep it on site in the event of a service call.

    As far as comparing units - I personally think the Prestige is a much better unit all around. Higher water content heat exchanger (less likely to go off on high limit with low load demand. Would not require a buffer tank. Very low head loss - no special piping arrangement required - can use a Taco 007F if you wanted in some cases. Utilizes a self cleaning, 439SS heat exchanger, swing out electrical panel for easy wiring access. MCBA logic board - same as Burnham, Weil McClain and Dunkirk/Utica. See attachments.

    Something to think about.
