most inexpensive condensing boiler

enough to be dangerous

What is the most inexpensive condensing boiler available in north america?

Two candidates I have found are Munchkin and IBC
( http://www.ibcboiler.com/index.htm )

anything else I should look at?

I'm looking for residential use in the 80,000 to 140,000
btu range. Modulating would be nice but not essential.

whenever I talk to a local contractor he just wants
to sell me what he is used to and knows nothing about
anything else.

80,000 to 140,000 is a large range. What is you exact heat loss. Then I would add about 20% to that. Thats the boiler size you want, then select the right equipment for the job.

Does it need to be

ASME stamped? Some areas require heating devices to have this stamp. Not all condensors do

Check the MZ and the Polaris condensing water heater also.

The Polaris used to be a great bargin, although not ASME stamped, and the tank volume made modulating a mute point. I think a change of ownership may have effected the bargin price, however

The MZ can be had with a small DHW tank under the hood, a nice feature! That is what I use in my shop/ office.

I have used these as well as Munchkins with good sucess.

just a thought

But whatever you decide to go with make sure you have service for it. You could put in the best unit in the world but if no one know's how to fix it you could end up with nightmares..IMHO..:)

is the one installed correctly.

The new NTI trinity 200 modulates from 25,000 to 200,000 and is stamped.
Not sure I want to be the first on the block to play with the new software. Been there, done that.

Here the lowest priced unit would be the NTI Trinity - www.nythermal.com
but I'll soap box a little. Your most inexpensive condensing boler will be the one still standing in 20 years and fully supported along the way. Few of us are interested in supporting every potential orphan that comes down a production line. Each new concept and new product line has the potential for failure. We try to review the market offerings, look at the companies behind them and ease into the newest technology where it fits with our client base. Regionally I have better access and support with the NTI product than others of the same ilk. Each of the products mentioned in the various responses to your query can be the right answer. It all depends on your local talent and the system parameters. By your e-mail address you may not be too far away, check us out on the find a pro link below. Enjoy.......Dan

add 20% to that?

Why would you add 20%? Heat loss calcs already add 10-30% to what is really necessary.

Which heatloss calc add 20%? I use 3 different programs.

lets talk prices


from the responses and some research it seems
that the lowest price for a condensing boiler
is in the C$2500 to C$3000 range (US$2000 to US$2400).

Does this sound about right?

I also conclude that a non condensing boiler will cost
about C$1800 (US$1200). Is this about right?
Of course the non condensing will require far more
expensive flue material thus closing the gap considerably.

Right now I'm leaning to IBC or NTI assuming I can
find someone in this area who can install it and service it.

20%??

Heat loss calculations are theoretical and use conservative assumptions. Many real houses have much lower heat loss than the calculations indicate.

In our house, heat loss calculations by different contractors came up with 150MBTU to 200MBTU. I knew better because I had studied our gas bills. I had them put in an 80MBTU Munchkin last month. Extrapolation of fall therms/degree-day usage (allowing for the fact that the Munchkin will not condense on the coldest days) indicate that 80MBTU is still slightly oversized.

Trinity

is well discussed on this board, IBC is not. Might want to check out Dunkirk Quantum 90, aka Utica UB-90, Bryant/Carrier BW9, Olsen Quantum 90, etc.

IBC

I am going into my second heating season with my IBC Boiler. It has been extremely reliable thus far. Their website is a little out of date and doesn't mention their VFC 15 - 150. The boiler is a modulating condensing boiler that is capable of modulating down to 15,000 BTU or up to 150,000 BTU. What is nice about it is that it continues to keep the efficiency throughout the range. I have noticed a savings in my gas bill last year and am looking forward to additional savings this year subsequent to my tweaking of the boiler supply temperatures to maintain condensing return water temperatures. I have attached the Caleffi LCI/Data Server to my system to log the boiler and associated zones.

Magic word with me I likey the looks of Caleffi:)

we are into this control also ,soon as we can get one:) being in alaska is like living in the twilight zone:)))
