"Only works when it is not cold out."
The boiler size seems appropriate for the house, as it is essentially the same size as the old oil-fired unit it replaced. Where the old oil- fired unit managed to keep the house warm for any weather that nature threw at us here in Providence, RI the gwa 105 *fails miserably* when the temperatures outside get more than a couple of degrees below freezing. When outside temperatures are roughly at or above freezing, the boiler will heat the water to the set point (180 degF), then circulate the hot water until it drops to somewhere around 40 degrees below the set point when it will fire up again. That's great. But when the outside temperatures get below that, the boiler fails to heat the water to the set point. It picks some point below the set point (roughly 40 degrees below...) and then circulates until the water drops another 20 degrees and decides it ought to fire again. This doesn't provide a comfortable living space and we are sub 50 degrees in here now. I can force it to go to the set point by twiddling the set point up momentarily to trigger the limit switch, but once I do that to get it to the set point and walk away, it quickly reverts to its regular misbehavior when I am not supervising it. This thing has done this since new. We had a tech out when it was first installed, and they thought the temp sensor was bad (per instructions in the manual). They replaced it but it did nothing. The tech had no other ideas and it went nowhere. The boiler essentially operates in reverse of how it should: it apparently lowers the set point (by some sort of programmatic override) when it is really cold and the water needs the heat to meet demand; it achieves the set point when it is only marginally cold and could heat the water to a lower temperature to meet demand. It has me wondering if a couple of electrical leads in the unit were miswired at the factory. What happened to products that worked right out of the box? I would never, ever recommend a Williamson-Thermoflow product after this experience.

Bought a house with a new Williamson Boiler installed. I installed an automatic water feeder, for it to run efficiently with no worries. Three years down the lane I started having all this problems I have replaced Ignitor, Thermo fuse, control unit and now I have to replace the Boiler itself. Am very disappointed with this brand, I'll never buy it again.

Had a new gwc boiler installed in November (after a week without heat/HW when the 30 Y.P. boiler died). Ran for 2 days and the installer was back to replace the ignitor (another day w/o heat/HW). Later that month it wouldn't start. Unplugged and replugged some of the sensors and the error cleared and we were back in operation. 2.5 months after install another episode where it wouldn't start. Played around with it and it started operating again. 4 months after install, the condensate pump was running continuously but not pumping (separate system from the boiler, but a nuisance nonetheless). The neutralizer had plugged and the pump was dead headed. Took that apart and unplugged it. 7 months after install and we are again without heat and hot water. This time it appears to be the supply temperature sensor. We live in a rural area, so day before a holiday weekend, cant find the part anywhere in the state. Part was ordered and a now a week later we are still waiting for it. Needless to say, not impressed so far. Not sure if we dare go away in the winter and trust the thing to work. Works well when it works. Just not very reliable so far.

"Wish I could upload pics"
These boilers are the worst design! I've replaced 3 in the last year, one I had to replace twice. The design of the sections allows them to separate, causing leakage. The factory blames shipping. Funny how after 30 years in the business I never encountered problems such as this, not to mention what it cost me in labor. It took me over a year to get the warranty on a $2,600.00 boiler. Oh, by the way, this is a Weil McLain product, stay away! I no longer sell any product of theirs. Also had issues with the warranty on their main lines as well. Funny how they don't list this boiler.

"Has not worked for a month straight"
Bought the FreeStyle boiler in October. The plumber has been here twenty times in the last five months. As I am writing this, there is no heat in my house. I am really sick of this product.

"I Love my williams thermoflo"
If you have been looking to purchase a new boiler look no longer! I bought my Williamson-Thermoflo boiler about six months ago and am glad I did not choose any other product. The system is very convenient, as all controls are located within my reach. The unit itself is very sturdy and operates quietly. I had a certified technician install it when it was first purchased and the setup took maybe two hours, if not less. It produces enough BTUs for what I need it for, and the power use is minimal compared to other boilers on the market at the moment. I have yet to have any problems with the unit, and I do not believe I will for some time to come. This is really a quality piece of machinery here! I would definitely recommend this to a friend or family member if they are in the market for a new boiler.

"Burnham 204PI-T2 Cast Residential Hot Water Boiler - Liquid Propane"
We recently moved to the Northeast and bought a home built in 1890. The home, of course, was in need of repair and one of the items that needed replacing was the boiler. We conducted online research, spoke with both family and friends about the type of boiler system they believed to be the cost effective and environmentally friendly. We went to several businesses that offered boilers and spoke with countless salesmen and the general consensus for what we were looking for was the Williamson-Thermoflo GWA - 140,000 BTU - Hot Water Boiler - NG - 82.5% AFUE - Chimney Vented - Up to 2,000 Ft. We needed the boiler to effectively take care of our hot water needs and run cleanly, which this model does so. Once it was installed, the system ran effortlessly and provided the entire home with exactly what it needed. Since it was a new system, we have not had to repair or replace any component however will still have them come out for an annual check up. I would absolutely recommend this unit to anyone.

We have owned the boiler for 15 years now. It quickly heats up our 2400 square foot house in a matter of a couple minutes. This boiler needs to be upgraded soon tho because of having a rating of 90 and below. It is also very high maintenance. I replaced the electronic and master control, but the electronic control managed to fail and disappoint me. I would recommend this type of boiler to friends and family. I own an older one, so I have positive views on Williamson, but do not know how a newer boiler would do. Overall, I have liked it so far, and I may just consider getting a one from the same company due to the amazing service it has provided for the past couple of years ..

"Williamson Great for 10 years"
We have owned the boiler for 10 years now. It heats our 1200 square foot house well. We have cast iron radiators. It turns on quick, and it is rather quiet and fires up nicely when it calls to heat. It is lower efficient rating, but it does not burn that much oil. I do wish it was newer with a 90 or above rating. It needs to be cleaned and serviced once a year or it does not run as efficient. I recently replaced the electronics and the master control on the boiler. The electronics failed after 10 years. Just like with a car, electronic components fail at about 10 years, so they did. I would recommend this type of boiler to friends and family. I own an older one, so I have positive views on Williamson, but do not know how a newer boiler would do. Overall, I have liked it so far.
