Great Boiler for a Computer Techie
from Hamilton, NJ
Comments about Ultra 105 - 81,000 BTU Output High Efficiency Boiler (Nat Gas or LP):
I use this boiler in a 5 zone residential application. It is a great boiler when it is working fine. Very hard to find qualified service technicians to service the Ultra 3. You need to be computer savvy and most service technicians aren't. It also requires more maintenance than a conventional boiler. What you gain in gas efficiency you will spend on maintenance. But, I love it.
Bottom Line Yes, I would recommend this to a friend

Do not buy
from Easton, MD
I would not buy this boiler. I've had TWO heat exchanger's fail. Both developed holes in the castings. Weil Mclain gave me a hard time trying to get them replaced via warrenty. I'd see pictures if I could.
Bottom Line No, I would not recommend this to a friend

WeilMcLane 105 Gas Boiler
from Lake Lillian,Mn
Residential Use Gas Boiler In the period of 1 year I have had problems that the Weil Mc Lane company has not been able to fix. Last year the boiler went out and after delayed responses and being without the use of the boiler for about 3 weeks the company replaced the unit under warranty. In less then a year the boiler went out again and the contractor has tried several new parts and the company has delayed action to solve the problem for about 1 month.The nights have averaged below 0 with several -10. Very poor support by the company Weil McLane.

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.
from Lake George, CO
I am using this in a home I am building.Found it easy to install.Works just like described.Service was the best.I will purchase from this company again.I will recommend this company to my family, friends, and acquaintances.Fast shipping, too.

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.

from roseburg, or
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.
Merchant response: Feel free to contact our Customer Service Team (888-757-4774) for help finding the additional parts you need.
