Trinity Boiler Question

...about someone experiencing problems with the domestic hot water heat exchangers in the Trinity boilers.

Is there a known problem, or was it a specific incident related to water quality? I am getting ready to quote a couple of these, and am concerned about the potential for problems.

Thanks,

Starch

    I have put in several Trinitys but only 1 with a heat exchanger for domestic.I have had no trouble with it but my preference is to go with an indirect tank(I use the Aerosa 40 gal).That makes a great package.The problem with combo units is that as soon as you open a tap the boiler starts and that isn't good for efficiency.If you have the option then I would try to package up the boiler with an indirect water tank.

    Good Luck

    Heavy DHW or well water

    should stay away from exchangers: easier to plug up and GPM rate is low. This apllies to all combo units.

    it twas me.

    If you read the manufacturers install intruct, see section on domestic water - it refers to piping an indirect on heating side. (not to use coil).

    When I inquired about this, I was told that the coils tend to plug up, and an indirect will give better recovery.

    so in short - don't use the T150/200C (combo), only use the T150/200 Heating only & use an indirect!

    Thank you....

    ...all for your replies. The one job in particular that I'm looking at has some SEVERE space limitations that make the domestic hot water option very attractive. It is a city-water application, also.

    Seems strange that the manufacturer would provide this option, yet recommend an indirect tank, dont you think??

    Thanks,

    I'm not a big fan of combo units

    Maybe you want to look at a small unit like the munchkin/perrless pinnacle on a stand with a lowboy indirect tank underneath. You could do the same set up with a Monitor MZ or BAXI Luna wall hung boiler and a lowboy floor mounted under it.

    Trinity Boiler Question

    Joe, are you calling the Trinity fat? ;-) It's way smaller than a Munchkin or MZ and a Luna is 20% taller. Any small boiler will work, it sounds like it is a matter of having enough room for the indirect. Maybe the Baxi Nuvola with a built in 60 litre (16+ gal) tank would work?

    Trinity's

    The only reason I'd use an indirect tank for a Trinity Combo unit is high peak DHW demands and the other is the slight delay in the ignition process while the Trinity fires and starts producing hot water. If you have a high peak demand, use the T200, with the reset controls and modulating gas valve on the heating side, you won't be too wasteful on the BTU's. You waste a lot of water while waiting for the thing to fire, especially if your fixture is far away and here in Colorado where water is precious, that can be a concern. The use of the smallest indirect tank would prevent that lag and provide recirc and give you that small footprint. Also if minerals are a problem in your area, just install some valves that you can do an acid bath if needed and consider some water treatment.Bad water can mess up more than a flat plate exchanger.

    All in all I think the Trinity is a good boiler but that's what I thought about the Glowcore, lol

    Trinity 200

    I am suplying domestic hot water and heating for a rooming
    house of 17 rooms with a T 200 .The indirect is an Optimyzer 45 from Thermo 2000 install sept 2002 and no complaint yet.Been told by NY better to use indirect if space is not a problem.

    We love our Trinity (and just my two cents.....)

    We are just finishing our second heating season with a heat only NTI Trinity T-150 paired with a Crown MegaStor indirect. After experiencing this, I tell all of my homeowner friends to consider a condensing/modulating setup of the type we have before going with a conventional boiler. Among the wall-hungs, it's hard to beat the Trinity's value for the dollar. I only wish more homeowners were aware of them. I know that most smaller manufacturers resist direct-to-consumer advertising and rely on the trades to get their product into residences, but maybe management should consider how Carrier and Lennox keep scorched air in the forefront of homeowners' minds with all of their ads to consumers. Isn't it time that somebody besides Viessmann advertised in This Old House????
