We had this installed in 2010, replacing the old big boiler and with the intention of saving money since we just started a family. The savings we are expecting are just not happening because, like what the other reviews say, it breaks every winter. The heat is still working a little bit but could only go up to 56 degrees. I called the technical support and they walked me through, I guess, resetting it. Based on the blinking lights they said my boiler is functioning just right. Then I waited 4 hours, and it was still the same. I called them back and the tech support asked me which lights are lit and what the screen is showing. According to him, there should be no problem and it should heat up the house but since I told him it didn't, he asked me to call a technician. I tried calling different technicians since this was built and none of them knows how to fix it. It has to be the technician specially trained for this boiler, who is located far far away. We have paid those technicians for nothing. When we found someone who could finally fix it, he asked us to buy parts because it needs to get replaced. What a headache. I guess I have to call PSEG and see if they could suggest a better energy efficient boiler that won't give me headache and not freeze during winter. Stay away from this boiler.

"Trinity Ti/LX 150 Boiler"

Very Unsatisfied

I have had this boiler for 5 years now and have spent over $1500.00 on repairs. Any savings in gas costs have been eaten up in repairs. When it works the house is warm & toasty, but too many times, as soon as the weather changes, it goes down. A furnace/boiler is supposed to work without worrying about it for years; not so with this boiler. The boiler that was replaced was 50 years old and just kept on pumping out the heat. I wanted a more energy efficient model and upgraded to this unit. What a mistake. At the present moment it is not working and it is 15 degrees outside with lake effect snows on the way. Thank heavens I have a fireplace insert.

"NTI Ti150C has worked well for first 6 years"

5.0 rating
Very Satisfied

Our Trinity 150c (hot water combo) replaced a 1940 cast iron boiler and rental hot water heater in fall 2007, six years ago. The gas usage went significantly down as expected, and our comfort went up because of the boiler's ability to modulate its burn rate to a lower rate when the outside temperature is warmer. We reclaimed floor space too. For a 1300 sq. ft household of two, the on-demand hot water works perfectly, capable of supplying adequate hot water for a shower and appliance or two (e.g.dishwasher, washer) concurrently without slowing down, even sourced with icy Ottawa water in winter. The boiler was recently opened and cleaned for the first time and needed almost no cleaning after six years. (Manufacturer states that unit should be cleaned and inspected after first year, as usage and local conditions may vary.) The only failures in six years were not the boiler itself. The external Watts overpressure valve started leaking this year and needed to be replaced. I see Watts now have an M2 version, so perhaps they have resolved a problem with the M1. Also, the secondary (radiator) loop pump was replaced twice under warranty since installation, but I blame the pump manufacturer Bell and Gossett for that quality, not NTI. I replaced the B&G with a Grundfos pump that does the same job, and is virtually silent and only uses 23W of electricity. NTI has all their installation and technical manuals on their website. I encourage anyone who is at all technically inclined to download and read the manual before purchase as I did, and keep an eye on your installer and installation. Ours did a messy job overall, but at least followed NTIs instructions properly because they had no experience when they did our installation. I recommend this model based on my experience.

Piece of junk. Installed in 2010, nothing but trouble. Now I need a new controller and ventor motor! Definitely a different brand, if I'm forced to buy a new one! Boilers should only be installed in Canada by trained and certified installers. Installers need to be more regulated so that you can expect some degree of competence!



"Fantastic Boiler"

Very Satisfied

We've had ours for 2 years now. It replaced a mid-efficiency boiler and separate gas water heater. Gas consumption was cut by way more than half and the house is warmer. The installation was very well done and the unit is almost silent. This is high-end, high tech stuff. We haven't had one hiccup. I did install a 5-gallon buffer tank to temper the changes in water temperature (shower). For the first couple of minutes, the hot water is on. I'd buy another or recommend these units in a heartbeat.
