Works Great! Jan 29, 2016

I would suggest comparing the 3 choices of boilers recommended. I just bought the top rated and didn't realize it didn't come with the pump as pictured. I probably would have taken the most popular second choice. Also, the relief valve was no good on my boiler so I had to purchase a new one. Otherwise it works great and was easy to install.

Arrived Complete & As Described Sep 12, 2016

Arrived promptly. Manufacturer readily available w/ live human beings answering the phone to provide tech/installation assistance. Straight forward installation w/ instructions, but would have liked a bit more detail on circulator placement. Installed & fired up in midst of cold snap. Only been a couple of weeks, but working without a hitch so far and heating house beautifully.

Great Heater! Sep 29, 2016

This little heater does a wonderful job of keeping my two car garage nice and warm all winter long. I use my garage for a man-cave workshop in addition to parking my vehicles. I purchased this one because 15 years ago I purchased an ADP similar model. Well, after 15 well used years of 247 running, the board went out. So, instead of replacing the board I opted to replace the unit with another ADP. I don't think you can ask for many more trouble free years from any heater.
