Review 1

Very reliable unit.

a year ago
This will be my 2nd identical comfort glow 3 burner heater. 1st one I bought 20 years ago ran by propane and it is still working perfectly out in my shop. This one is a Natural gas unit for my house and we will be using it for emergency heat in case of a commercial power outage. Because both units are all mechanical there really isn’t much that can go bad. The heater my shop does have the optional blower but it doesn’t require it to heat. So if you are reading my review know that this unit is extremely reliable.

Yes, I recommend this product.
