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
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.
Last year I got a System 2000 boiler from a local dealer for
www.energykinetics.com 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.

service call the first year for a minor problem covered under warranty.

www.heatinghelp.com 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.
