I install Triangle Tube boilers. I started selling them because they were the best, and they still are. NTI uses that awful Honeywell interface, Lochinvar is cheap junk, and Viessmann is so effing complicated that you have to work on them all the time just to be able to service and diagnose them efficiently. That said, I have seen so many nightmares in my neck of the woods that are all of them, all of them due to installation errors from shoot-from-the -hip hydronic "specialists," and salesmen with tools. Rusted tank? Why is your system oxygen rich? Error codes? What's your piping look like, and where are the pumps? Seriously, consumer reviews need to he eaten well salted. ACV (Triangle Tube) makes a totally decent boiler that is easy to use and easy to service. That's important in the Yukon, because service calls can come with hefty travel fees. Install 'em right, get some low temperature emitters, and watch your drain drink the condensate. That's your savings right there. I have aPT110LP Solo boiler on radiant ceilings, and my system operates at less than body temperature until -10c. I get a hydronics-nerd orgasm just thinking about it. Sexy stuff.
