My suggestion is to have a very experienced high efficiency furnace plumber install the unit. From what I now know all aspects of the system need to be in balance to work properly. My unit is exceptional and my wife likes the colored pictures designating the various modes of operation.

Great Product Aug 18, 2016

The product arrived in less than 2-weeks. The unit is a high quality boiler made in Minnesota. This one was for my personal home. If you need questions answered or tech service, they are top notch. They know their product. This unit has been in operation for about a month and works flawlessly. I also have one of their plenum heaters, in use now for 12 years, without any problems what-so-ever.

Not Great Sep 21, 2016

Not great... wish I kept my 40 year old one... it worked a hell of a lot better.

Till Now, Excellent Quality Jul 31, 2016

I have installed these units for last one month only and they seems to be great. Very quiet units and very efficient. I have installed total 7 units and all are running fine. I think everyone should get them installed by professional installers.
