What to replace a Triangle Tube PS 60 with?

Now that TT is gone someday in the near future I'm going to need to replace my boiler, which is working fine for now.

Fifteen years ago when I was going to put Hydronic heating in my 200 year old house. I asked Heating Help guys what would youse recommend. A lot said TT is a good realible unit so I done the heat loss and ended up with a TT PS 60 propane. It took me most of a summer to install all the heat emitters and all the copper tubing, Went to TT training in NJ and then about 6 weeks later went for training at TACO in RI. Bought the boiler and installed it no problems. Over the last 15 years I've replaced a few parts a couple inginaters and a venturi and blower motor which wasn't to bad. So which ever boiler I get I'd like to have training available. So what are you guys recommending? Any suggestions would be greatly appreciated. Thanks

    Rinnai is makes good boilers. They are likely to be in business for a long time. They have good tech support, training etc.

    Hi you said you replaced the venturi and fan, were these at the same time? and what was the manner of failure of the venturi?

    Another Triangle Tube to replace it.  There are a bunch of brand new boilers, tanks, and accessories in the supply houses that will be offloaded at huge discounts as a result of the closure.  Grab one of them and the control board that it uses.  Most of the rest of the parts will be accessible or can be replaced by generic stuff.  If you get the same model then many of the parts will be interchangeable.

    Just a thought.

    After you make that expensive repair and you still have the same problem, What will you check next?

    Thanks for all the replys. What Ed The Heater Man really got me thinkin, if I replaced it with another one just like it I wouldn't have to repipe it. It would just matter of removing the old one and replace it with a new one reconnecting the piping and reattaching the wiring. The problem is I haven't been able to find a supply house that still has one in stock, though I've only checked the ones on the internet. So does anyone know of a supplier that still might have one? I'd appreciate any help. Thanks

    where are you located? @GGross has some inventory at his wholesale business

    A wholesaler in Illinois had 50 boilers in stock when I saw him a few weeks ago.

    Look for the former TT rep in your area, they should know where inventory is

    yours is a ps60, you will have to modify pipe and flue pipe some as current models have changed some. I would be more inclined in using a new boiler that is still actively made and supported.

    Yes I think the piping at the bottom has changed. We were not carrying many of the Prestige models when TT when out of business, mostly have the Instinct boilers still. We are parting them out soon , only keeping a couple around in case one of our dealers has a catastrophic failure in the next few years. Parts should be available for most models for a good long while.

    I’m in the same boat, I’d like to hear more about interchangeable parts. I have a 110 going on 13 years old. All original parts.

    I don't believe that there are many new boilers in stock that will match your 110 from 13 years ago. You may want to stock up on the common repair parts like the control board, gas valve, blower motor, and ignitor, while they are still available.

    The idea was to purchase an identical boiler, that way you have every part that will be interchangeable with the boiler you already have. With a 10 year old boiler, you may not have that option.

    there are no interchangeable parts between the older models and current.

    Heat exchangers on these boiler have a theoretical max life of 15-20 yrs if serviced and cleaned every 1-2 yrs. If not regular but infrequent 10-15. That’s from our experience servicing many over last 20+ yrs

    I have had it cleaned 3 times total so I guess I will have to start thinking about a replacement…

    I know it doesn't matter now, but one reason I went with TT was they had a lifetime warrentee on the heat exchanger.

    I tryed to contact my supplier that I bought my boiler from to find out if they know of any other suppliers that might still have on in stock. They to are out of business. I guess keep lookin.

    I have never heard that Triangle has a lifetime warranty Rich Davis. Yes, they have shut down operations in USA.

  • Giannoni HX's fail daily, but I've never seen a firetube failure. Clogged perhaps, but never breached.

    I was told that F.W. Webb acquired a lot of TT inventory and would be supporting the defunct brand.

  • Rich Davis_2
    Rich Davis_2 Member Posts: 128

    Thanks guys for the suggestions. I called Webb and they said they don't have any PS60's, Another question if I were to get a bigger boiler like maybe a PS110, what would I have to do to my system to make it work properly. I have already done a heat loss when I installed my PS60. Would it short cycle beacuse a bigger boiler? What boilers use a fire-tube HX so if I have to change brands?

  • hot_rod

    TT boilers are mostly 5.5-1 turndown, what is your smallest load. Ideally the boiler turns down close to the lowest load. But any modulation helps with cycling. The PS 60 was also 16K on its lowest turndown.

    I'm pretty sure a 110MBTU model TT boiler would be fine.

  • hot_rod
    hot_rod Member Posts: 27,329

    Many of the mod con boilers allow you to limit and lock the boiler to a lower output. If your heat load is say 40K, lock the boiler to around that. That helps eliminate the cycling.

    Additionally some boilers have step firing where you limit the firing by steps and time. Keep it at 10% for 10 minutes, 20% for 10 minutes, etc. That fine tunes it even more.
