Nice Choice Oct 25, 2016

The radiators went together very easily with the connections provided to the heating pex and there were no leaks. very easy to bleed. they provide much more heat than I was getting from my old wall convectors and seem to retain the heat a long time after the boiler is off. Not hard to hang either as long as you separate the hanger prongs in increments of 1/2 inch. Also, my wife was pleasantly surprised by the appearance

I have owned this same 400k btu unit for 8 years and it is the best purchase that I have ever made. It is used in a commercial setting and has never had a problem or service call. Reznor quality is second to none and definitely worth the extra cost.
