Trinity Boilers

JIMBO_2

I am thinking of installing a Trinity Ti-150 boiler in my house. It's a 2-story house with 7 CI radiators, fairly good-size radiators, and 20 foot of CI baseboard. The supply and return lines are old 2" steel pipe, about 20 feet of each, supply and return, in the basement. Currently I have an old 1956 Weil-Mclain oil-fired boiler, and a gas hot water heater (we disconected the boiler's domestic water coil years ago). Seeing the small size and weight of the Trinity unit, I cannot help but wonder if it'll DO the job effectively. Any ideas or suggestions will be greatly appreciated.

Jimbo: I've put in one Trinity (propane) and I was impressed; however, I only had maybe 120' of BB and a 40 gal Amtrol. You have a TON of H2O in your system. I'd call NYThermal and ask them. If I were them, I'd donate a boiler just to see if it could do the job. Their book says max. outputs of 137MBTU (Natural) and 133MBTU (Propane). I think you may want something that holds more water.

What is......

....the calculated heat loss of your home????

That is where you need to start - then you can select a properly sized boiler!!

John is correct. It all begins with a heat loss calc. Always and there are no exceptions... perform or have a calculation performed anytime HVAC equipment is being considered for replacement. The Ti-150 may very well easily handle the radiation and load imposed... or you may need a Ti-200. Once a load calc is done, the next thing you need to do is compare the total available radiation. If the home has been insulated, replacement windows installed or other energy upgrades, the radiation available may now be oversized. This could lend to lower supply water temps needed and consequently, higher equipment efficiency and lower fuel bills. Without a calculation done, any choice of equipment is just a guess. There is a load calc for use on this site or your contractor should do one if he hasn't already. Greg
