I'm very happy with my purchase. Installed the unit in my shop, and it heats it up without any problem. The fan is very strong and moves a lot of air. The unit itself has many mounting options. I choose to use a combination of 2x4 and 2x6 to mount it. Some things to note is that you will need the exaust pipes, which are not cheap, the gas line, power cable to wire in, thermostat, and thermostat wire. Overall does a great job.

Excellent Customer Service and Pricing as always!

I did a self-install of the GG75 in my 2 story pole barn. The instructions were easy to follow, especially with the piping kits. This heater runs really quiet and heats the pole barn quickly. I added a wifi thermostat and can have it heated up before I get there. The shipping was excellent and packing sturdy and the heater arrived in perfect condition. Very happy with this unit.

 

Easy purchase process. Easy install. Works consistently and very well.
