90% efficiency hot water heat boilers

[woods]

Does anyone have any experience with the high efficiency boilers? I'm considering replacing my 25yr old boiler with one of these, but I'm hearing from some people that they are nothing but high maintenance trouble.

I don't think that any of the really high efficiency units have been around long enough to determine what the overall savings might be. People who recently bought high efficiency units tend to sing their praises, I think partly to justify what they spent on them. If you're lucky enough to have one that does what is should, and doesn't break down, you'll probably be very happy with it. Conversely, if you had breakdowns, problems finding competent service people, proprietary parts that aren't locally available, and cost an arm and a leg, you will probably feel differently. There are plenty of people on both sides of the fence, I wire about 25 boilers a year, mostly standard units, maybe five or six high efficiency units. Most work fine out of the box. We did have a bit of a problem with a Triangle Tube condensing unit, and a pretty much major failure with a Peerless wall hung condensing unit. Buderus wall hung condensing units seem to be a favorite, a pita to wire, the way they're laid out, but the customers love em.

Can you expand on the bad experience with the Triangle Tube? I keep hearing good things about them, especially the heat exchanger.

Last year I got a System 2000 boiler from a local dealer for

Mine is oil fired and I saved 32% in the first 3 months and for hot water use in the summer, even more. I won't have an exact figure until I get another oil delivery, but I'm at least 225 gallons saved over April to Oct. last year; I still have almost a half tank. It is trouble free. Gas models are available too. .

At work in one section of our building we have a gas fired Munchkin.

It has been through five winters with one service call the first year for a minor problem covered under warranty.

The unit had a bad board, it kept firing then shutting down. The techs at TT were really good, and very helpful. The replacement board solved the problem.

is only boiler pros, post at "the wall" for alot of help. Althvac is alot of hoes post there to be reamed Get the offered-optional 10 yr warranty and have the boiler on a good surge protector. One thing few salesman will tell you is boilers condense or operate at full highest efficency at no more than maybe 140f, at 180f it might be a loss of 4-7% efficency I am Guessing. I know my radiators can only heat my house with 140f until its near 30f out, at

-20 I need my unit set at 175-180. And if you setback temp you may always need high boiler temp and loose efficency. You may be under radiated and need higher temps than I need, so alot of the extra savings you may never get when you need it most. You have alot of research to do, I will bet your boiler is now set to go to 180, but here in the midwest its to warm to do any testing. Look at the System

2000 for non condensing and do your research.

Thanks for all the good replys. Looks like I have some research to do!
