  1. We heat a 5600 sq foot ranch. The footprint is 2611 with a room above my garage. The basement floor has pex tubing in it and is one zone. The first floor is another zone with an air handler along with the room above the garage (just under 400 sq ft.) The home is foamed w/ 2×6 insulation and low e windows. Its 4 years old. We have rural septic/well water. At the suggestion of my now unemployed builder we installed a Quietside “Boiler” (QVM9-150 65k-135k modulating) with a 50 gal reserve tank. It handles the load fine WHEN it runs. It failes about every 3 months and I have a bucket of parts in my basement. I want it out! I have a quote for a TT or a Viessman for about 13K. I need advice. People say Viessman but there are few who work on them. Others hate Viessman. Few say bad things about TT. All say Quietside is junk and I agree. Help. We live in WI so it’s cold.

  2. I had very bad experience with High Efficiency Triangle Tube Prestige (399,000 BTU). It was installed in 2008 in my new house at my plumber’s advice. BIG MISTAKE! I should have gone with Buderus that my architect had proposed (more expensive but supposedly very reliable) or with some other, like Lochinvar (which would cost less than Triangle Tube). There was a problem almost from the start when the unit shot down and I had to call my contractor to get it restarted. Then there was another shotdown a year after we moved in. The company rep at the customer service was extremely unhelpful – borderline rude – and made it kind of clear the customer service is really not for the customers, only for professionals. Curiously, the rep mistakenly thought the problem was with the defective control panel – they’d had many issues with it and had a recent recall but even then they wouldn’t replace it for me at no charge!
    Eventually my plumber had to spend two days first trying to figure out the problem and then fixing it. As it turned out the blower (brand new, bought with the system) went bust. That was for no good reason, since the boiler room is all tiled and surgically clean, with no dust at all. Then I learned they only give insurance for 1 year which is a scam since it always takes a long time to finish the new house and move in after the boiler is delivered, so they really cover it for just a few months. And no one ever offered me to buy extended insurance. Now I had to pay $1500 full price for the new blower – they knew they had me and didn’t even have courtesy to offer a discount. Repeated calls to their distributor in NJ led nowhere, and at the insurance dept at Prestige they won’t lower themselves to talking with an end customer, insurance is really not for that in their view. A rep at their distributor’s company promised to take care of that, but instead simply wasted my time and eventually wouldn’t answer the phone or return the calls. So Prestige has no prestige in my book, my advice is go with someone else.

  3. Jim I have been in the hydronic heating for about 10 years. I have installed Teledyne Larrs, Wells McClain, Burnham, Viessman, Crown; and many Buderus and Triangle Tube boilers. Your best bet is to get a cast iron boiler by Burnhan, Viessman, Buderus, or Crown. They are all pretty rock soild units, however controls on Viessman and Buderus get a little more complicated. A cast iron unit from Crown should integrate to your current controls alright and be cost effective. Flue pipe issues could be a problem, so you may be more inclined to go to a condensing boiler. Venting can be done with soild core PVC pipe and depending on what you already have this may be the way to go. I have done Buderus condensing units and won’t do again. Shy away from aluminum heat exchangers, they break down with the acidity of the condensate, also the controls are complicated for the homeowner and heating contracter (unless this is all you install). Viessman makes a great condensing boiler, stainless steel heat exchanger, great unit, expensive, controls not easy, but great unit. Triangle Tube Prestige, one of the best units I have installed. I have done more of these than any other. I have temporary fired these on many jobs, premantly fired these within day(s) of installation and never had an issue. They are easy to pipe, install, control, nice for the homeowner to troubleshoot and have consistanly worked above and beyond not only my expections but also the homeowners. Based on the systems I have installed, I would recommend a Prestige boiler for your home.

  4. I keep getting a javascript error popup when I attempt submitting a comment. Does this happen for anybody else? I do not exactly have the most current computer so possibly that is the issue.
