Working well through many cold nights
By Lance Trusty
from Billings MT
Comments about Ultra 230 - 183,000 BTU Output High Efficiency Boiler (Nat Gas or LP):
We had three of these units installed in 2 old 1930's building that has many old radiators. The system has ran without a hitch since 2012. The system regulates the water flow and temperature by a thermostat outside and inside. The system is easy to monitor and makes the Maintenance Departments easier and more efficient. It has gone through 2 extreme temperature winters in very inefficient insulated buildings without a hitch. Very easily the best piece of equipment in use in our buildings. Highly recommended
Works Exactly As It Was Intended
By Rich The Snow Guy
from Oregon, Illinois
I live in Northern Illinois whare we have some fairly unpredictable Winter months and my house sits on top of a hill and my driveway looks like a ski slope. When we built the house 13 years ago I had begun to research a hydronic snowment application and last year I was finally able to put together enough monies to have a 5" thick concrete driveway poured with 3000 feet of 3/4" Pex installed in the concrete. This boiler is the backbone of the system and its efficiencies were definitely taken into consideration. Lets face it, the worst energy application one could have is to be throwing BTU's at concrete to melt snow & ice. I kept the installation simple with no automatic controls to sense slab temp or outdoors moisture and that was my choice. I had a day last Winter that we had minimally 1/8" of ice on my driveway and we had 30 mph winds with a windchill factor of zero. I turned the system on after all was done and in 1.5 hours it was melted and had run off. Sure beats me trying to get rid of it by hand. The boiler is as expected and I am about to install a indirect hot water heater and use it for that purpose as well.

A superior product
from Dublin, Ohio
This boiler replaced a pair of older Dunkirk boilers. The Dunkirks were the most unreliable pieces of junk ever sold I think, and the company making them were HORRIBLE at providing warranty repair service. The Mclain Ultra 230 is generations ahead in technology with a microprocessor boiler control, multiple levels of programming, diagnostics and the ability to make the boiler operate to your individual installation. Mine supplies hot water to three fan/coil air handlers covering four heat zones in the hose and a DHW heat exchanger. It took me a few minutes to program the boiler to my system and it has operated flawlessly ever since. I had Weil Mclain come to the house to look over the installation and they measured the exhaust gases which were within 0.01% of the specified CO2 levels. The CO emissions were exceptionally low as well. My measured eifficiency was about 93% with an outside air temp of 29 degrees. Not too shabby!

An excellent high sfficiency boiler!
I have installed this boiler in my 7,000 sqft home. It supplies hot water to three fan/coil air handler's covering four zones in the house. It also supplies an 80 gallon hot water heat exchanger. Ive followed the installation schematics exactly and used the prefabricated header supplied by Mcclain. I have six Taco pumps running the various fan coils and DHW heat exchanger and all my lines are insulated. I had a manufacturers Rep come out to inspect the installation and got the thumbs up. We measured the exhaust gases and found almost perfect CO2 and carbon monoxide readings. My measured efficiency was 92.7%. I've been using the unit through half of this first winter and the results are excellent so far. It is a vast, vast improvement over my old Dunkirk non-modulating boiler. The microprocessor controls are decades more advanced than the ancient technology of the old clunker. I'm very happy with this boiler and would highly recommend it!

So Far So Good
from Los Ranchos NM
I installed this boiler following one of the many plumbing schematics included in the manufacturer's manual. It fired right up first time and has been working fine for a month now. Positives-small and light for a 183K btu/hr boiler, quiet, efficient, intake and output heat sensors regulate the heat modulation.Negatives-only time will tell, I added the water conditioner that came with the boiler to protect the aluminum heat exchanger, but don't know what the life expectancy is. The list of annual maintenance before firing up each fall is extensive. I am unable to check the combustion gasses for CO and CO2 emissions as I do not have the equipment so I can't fine tune the venturi. I am hoping it came preset right from the factory. Also, since this is a condensing boiler, it produces a small amount of water when it is burning which has to be collected or drained.
Merchant response: The excess water will go to a drain. (All high-efficiency boilers are condensing boilers, which means the the steam exiting through the flue is several hundred degrees lower than a standard boiler; as a result the steam condenses and as is passes back over the heat exchanger, the remaining heat is utilized by the boiler rather than being vented out the flue.)
