"Re problems all having"

5.0 rating
Very Satisfied

In general these boilers are quite reliable; the Eo2 errors can be attributed to a poorly grounded circuit, no annual maintenance and/or sometimes one of the earlier version solo boilers had a weak ignition transformer in the MCBA control. This sometimes is covered under warranty but must be verified by qualified mechanic and only covers part. This is discretionary by Triangle. The blower failures are a lot of the time caused by flue gas recirculating to combustion air pipe. Vent termination is critical to follow instructions. Sometimes we have seen blower failure just due to premature failure but not very often. All people with issues really need to find a local company who is well versed in service and install of high efficiency boilers. Make sure if a service tech is not sure what is going on, they need to call Triangle Tech support to go through proper testing and diagnosis of issue. Hope this helps some of you. Cheers

"Homeowners Attention"

I am a plumber in Northern NJ and have installed several hundred of these personally! These are one of the best products on the market, not to say they don't have a problem here and there. If you are buying one don't buy it online because you don't know how it was handled before it got to you, these are not meant to be dropped or kicked by UPS drivers! Ask questions of your installer, ask your installer if he has been to school by Triangle Tube and does he recertify himself every two years? If he doesn't don't use him! I have been to class with guys from across the country. This is not a do it yourself type of project. Don't knock the product when you should be knocking your installer! I have problems with less than 5% of units I install.

"These things are killing me"

To start off with, I am a licensed plumbing and heating contractor. I have installed over 30 Triangle Tube boilers. People are saying installer error is most of the problem. Here's my experience. Had three bad Tanks in the prestige. 1. Bad weld from nipple to tank 2. Pinhole in tank? 3. Cracked nipple going into tank (split on seam). Power switch on new Trimax faulty. Boiler just shut off. Brand new. Bad domestic water Temp sensor Bad weld on internal circulator flange. E2 errors on 4 Trimax boilers = countless unpaid service calls. Ended up changing boards (fixed). Never mind all the times these locked out and I had to go reset because customers did not know what to do. I don't know if they got the challengers sorted out. Installed 3 challengers. All locked out on failure to ignite or fan speed issues. "Change fans," they said. Changed all fans still locking out. Rep came out and reprogrammed the computer. Two of three all set. Again after several service calls (unpaid) I changed the whole computer out and so far so good. I worry that at any moment I am going to get a call from a customer. " My heat's out again!" "I want a new boiler!" "I got a lemon." I want my customers to be happy. They are not and neither am I.

"Boiler design and set up is critical"

5.0 rating
Very Satisfied

This is not a boiler that you can just hang on the wall and put power to. This is a precision piece of equipment that requires precision combustion analysis equipment to set it up properly. I've installed about ten in the last two years, new install and retro-fit applications and the only problem I've encountered was a propane set up issue with having to tune it slightly outside of the manufacturers specifications. That issue was remedied with help from the factory. No big deal. The natural gas installations have all been flawless. My advice, find a contractor that understands the water side of design as well as providing proper load calculations on the home. As with installation of furnaces, boilers, water heaters, or any appliance, the most important aspect of the equipment is proper install and set up. Any monkey can install something, but only a pro can make it truly a positive buying experience.

"Nothing But Problems"

1.0 rating
Very Unsatisfied

Installed this propane boiler for hot water and the in floor radiant heating in our new home (2008), and right from the first winter I have had nothing but problems with lock out after lock out. After 3 years, the main electronic board had to be replaced. $1,100.00, I have to hit the reset button every other day because of a lockout. Now, the boiler shuts down on low water pressure so I have to add water to the system to clear the lockout. I have to call a tech again. Not very happy!!!!
