The unit met the needs of the room it was installed in. Heater is a compact easy to maintain unit that will serve it's purpose well.

This Sterling GG60 is a good value and is very well constructed. I initially intended to install a Hot Dawg heater which I have used in other applications and decided to try this lower cost alternative. This worked out excellent and I would rank the quality of this heater slightly above the Hot Dawg, even though they are good product as well. Net was I saved a few bucks and got a better unit. The service from ACF Greenhouse has also been outstanding. Keep up the good work.

GG60 Sterling Heater, First one came had some damage called ACF and Eric had company come back same day and pickup and ordered new one. Received new one about a week later! Product is made very well, Have not hooked up to gas yet still waiting on propane company to run line. Just want to say if you are looking for company to buy online with ACF is the best! ERIC and is staff handled any question or problem like a pro. When you call them they answer phone. Thanks to Eric and Staff

just installed this heater and is working great after I had to reattach the fan blade that was just hanging there.

Well-constructed, nice heater. Easy to hook up, adjust and works very well for my 4000 square foot shop. AFC was great to work with, shipping was right on time and no damage.

High quality and fit was also good, I've used it now thru the 2018 winter and has worked very well it's very quiet compared to my 60,000 BTU one I had before this one.
