Good but retailer's price is too high
from Briarwood, NY
This is a good boilers but when things go wrong you cannot purchase parts in local hardware store, you have to purchase via internet. This is my third ultra 105, problems I had was computer and blower goes bad after three years.small price to pay for a low gas bill. I recommend that you do all copper and brass instillation , If something leaks it will be an easy fix.

Comments about Ultra 105 - 81,000 BTU Output High Efficiency Boiler (Nat Gas):
Have had installed about 3 years. Zero problems. Things to note: with Aluminum heat exchanger,if antifreeze is used, mfr recommends antifreeze specific to alumnimum boilers. I bought Hercules cryo-tek 100/AL on line. Also mfr recommends boiler water ph range 7-8.5. My well water was acidic, i.e. PH between 6-7 so I made a separate closed make up water system and used distilled water from local market. The alternative to a separate system is treating water to bring ph within specified range. My house has some small zones so I opted for Wilo variable speed pump which automatically adjusts flow to the zone size.

The boiler heats my 2700 sq ft house. It started up very well. The diagnostics are great.I wish it came with more inhibitor. I added it to the system, now I need more to complete the job and can not find out where to get it.
