This is a Fantech product-which is the best ERV on the market...It's performs beyond the specs. Very installer friendly-well built including service features. Delivery was right on time-with superb packaging...Thanks for the fast delivery and assistance.

Williamson-thermoflo Gsa-125 - 78k Btu - 82.9% Afue - Steam Gas Boiler - Chimney Vent Review Sep 13, 2016

Built by a division of Weil McLain the boiler it is similar to their products. Seems to be build well and I hope to have years of trouble free working status. A little difficult to install given the position of the ports. I will recommend this product to others.

I absolutely love this product. I contemplated installing this for years, glad we did. Works excellent, I also purchased the timer switch which is awesome. Each motor consumes 30 watts. Which is calming to electric bill.

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.
