Work Great - Easy Diy Install Aug 16, 2016

Easy to setup and the optional install kit had everything needed for the job. Unit came missing a panel cover and still am waiting to see if this gets resolved.

Emergency Replacement Aug 23, 2016

Away from home for the winter. Family checking our home found the problem, needed a new boiler. I was in another state, went online (this boiler was recommended by the professional), able to work well on your web site. Called a few times with questions, very helpful. Shipped out immediately. Boiler installed without any problems. I returned home a few weeks later to a warm home new boiler, and every thing working well.

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.

This was a replacement for an old thermostat in our office from 1990 that became a pain to work with. The new product was delivered very quickly. We are very happy with this one.
