Trinity 150 OK?

Josh_10

All I can say is by the time you install a Taco 0011 to push through the heat exchanger you could have bought a Buderus! I can't believe the pressure drop across the heat exchanger of the Trinity.

I would definitely install a buffer tank for you instance though. You could most likely heat the house on the coldest day of the year on low fire.

Just my two cents.

Small new house, only 45K Btu/h heat loss

We'll run water at a max temp of 120 through a system that has radiant in some places, and panel rads in others.

With the total heat loss, down at our design temp of -30F, being 45K Btu/hr, can we use the Trinity TI150C mod-con wall hung? Is it too big, or will it work OK? We don't want to be short-cycling too much in the shoulder seasons.

The budget cannot sustain much more, and locally, for parts and service, we had better be using one of these brands: W-M, TriangleTube, Trinity, Buderus. That's it.

They also have a Ti100

although some dealers aren't stocking it yet.

Buffer

If you are considering using a buffer situation, let me offer this:
A properly sized Mod/Con with a Triangle/Phase III Smart indirect: The Smart tank is a tank-in-tank design, which would allow you to use the outer tank as a buffer, while effectively reclaiming any unused heat into your domestic hot water. Now, a Triangle boiler (Prestige 110 perhaps) would be a fitting choice....

Use Prestige

Prestige - built in circ / indoor outdoor reset. Honeywell MCBA logic board - same as WeilMclain uses. Much lower head loss. Uses 439 S/S and a vertical self cleaning heat exchanger. Much better choice - probalby cheaper too. Much easier access to parts.

Have a customer who was a Trinity service agent change over to Prestige boilers because he could not get parts in timely fashion and did not want his customers to have indifinite down time when a problem occurred. This must have happeneded to him otherwise why change?

Trinity pump

NTI reccomends a 009 for the 150 not an 011. big price difference. NTI does also make a 100 that modulates down to 15,000 BTU.......something you won't get with the prestige. Guy is right tho..... the triangle tank can be used as a buffer. this is a good option in those milder months. Wow, you guys sure pay alot for an 011!(all in jest)

Plumdog_2

That is something to think about

The curve for the 009 is VERY steep! I question whether that pump is a good match for that boiler. If you were to pipe up a 009 on your primary loop and compare the boiler head and required flow rate with the pump curve, you may not be able to extract the full load from the boiler, say when in DHW mode. I must ask the factory.

take a look at a knight. might fit your needs better.



what's with that # thing you hafta do before you can post?
