Review: Excellent Product - This gas heater was a great purchase. I am preparing my mom's home for the winter after the last bad storm. It is a great way for emergency heat. It has a battery for the fan so that when the power goes out, the fan will still work. The structure is well made with steel and a white paint. Everything was included even the battery for the contractor to attach it to the wall. Easy to use and turns off if the fire goes out. Great product!
Review: Simple to install, lightweight, easily lit. - Easy to install. I won't use it until winter, but the pilot flame started easily and its ready to heat my greenhouse.

### ⭐⭐⭐⭐⭐ It's Keeping Us Warm
*by A***. on January 30, 2026*

Very happy with this heater. We use it with propane; and purchased this to replace a kerosene heater that cause a layer of grayness on the walls and and had a that smell. I love that there is no smell and that the propane is cheaper than kerosene. The instructions that came with the product could be better, but the product itself is great. The heat output is good as it It warms the den and living room of our house. The blue flame is attractive and I find looking at it quite soothing. It is a good value for the money.
