"Save your time and money"

1.0 rating
Very Unsatisfied

Bought this unit for a customer from Menards. Neither Menards (had to be purchased from them per development restrictions) nor Westinghouse will stand behind there product. With my own money I am replacing this boiler with a Navian ncb 210 (amazing boiler). I have installed 100's of boilers with no issues, this boiler has been a problem since day one, sensors failed, 3 way valve failure, then unit lost all pressure and they refused to help. I assume it is leaking out condensate, but John at Tech support for Westinghouse, wanted to blame everything else, rather than come up with solution. Please keep an eye social media with hopes of a tannerite explosion. Hopefully it goes viral. Don't buy!!!!!! Save your money, by a quality boiler.

"Condensing 95% Combination Natural Gas Wall Mount Boiler/Water Heater with 140,000 BTU Input"

2.0 rating
Somewhat Unsatisfied

I've owned this for about 5 months now. I was happy with it at first. The installation was quick and the plumber was really nice but after a couple days I wasn't happy. It works but it doesn't heat a lot of water so if you have a family it isn't a good fit. But it's good for a studio or guest home. If that.

"Great for Limited Use"

4.0 rating

A boiler should produce hot water on demand, and for that this works moderately well. It's well priced for the annual fuel efficiency (often the cheapest in this level) but the amount of output is minimal. We have a beach house on the coast, a small "cottage" like structure and for that it seems to be adequate because there is only one bathroom so only one shower will be pulling from it at a time. But if you plan to do back to back showers for multiple people, it will likely run out of hot water. It's not great for families because of this. It came with the house as an existing appliance, but I would probably not replace it. I much prefer the standard gas water heaters but to be honest I have no idea why some houses are built with boilers and some with water heaters so I don't know if it's possible to change that out directly. I would say that overall, in the five years that we have owned the beach house we have adapted to its output level and it's not a huge inconvenience to monitor the length of showers…but I would not purchase it again. When it stops working we are going to a different system. If I had to use it daily, I would have already replaced it. I don't believe we've ever repaired it (but we have a management company that oversees repairs so I'm not certain about that.

"Noisy thing"

2.0 rating
Somewhat Unsatisfied

We installed this unit in our new home after researching it. We saw it at Menards & thought hanging one unit versus two would be the way to go. We have had so much trouble with the condensing filter vibrating loudly ever since we filled the darn thing. We called customer service & of course they said we were at fault, needed to purge more air out of the boiler. We did that and it still vibrates. Had a plumber over, he wouldn't work on it. Had another plumber over who said that there wasn't air in it, just going to be loud. It heats for our radiant heat. It heats for our domestic water but the noise it makes is terrible! We removed the cover off the condensate filter to help reduce the vibration against that, stuffed foam pieces in between the filter & housing to try to reduce the noise but it's still loud. Not sure we would ever buy this one again, we are disappointed. Customer service sucks too. They don't want to talk to the consumer.

"Efficient and space saving"

5.0 rating
Very Satisfied

Last summer I replaced the old boiler in my home in anticipation of the winter months. It was getting old and our gas usage was off the charts. This new boiler is compact compared to our old unit. We also use it for hot water which is great considering we do not need an additional water heater for our home. Purchased this unit from Home Depot using their store credit option, I think the savings overall will pay for the unit itself in a few years. Another point to make is that this unit is very sleek looking for a boiler; Westinghouse did a great job designing the unit.
