I have owned many different brands of these. This is the best so far, of any of them. Smooth flame adjustment. Turn it a little higher and it doubles up the height. Has electronic battery starter. Nice shaped grill and body. Recommended!

I installed the Mr. Heater 20,000 BTU gas heater in my home. When ready to start it up, it took numerous times of pressing the ignitor button to get it lit. The heater works and heats fine. But there are major issues with it. First, I was surprised that it flames on and off according to the setting you choose. (The pilot light stays lit but the flames cut off completely.) I thought the setting would indicate the size of flames. I am used to an old Deerborn gas heater. I prefer that the Mr. Heater unit would adjust the size/amount of flame when the number dial is adjusted, and not turn the flames completely off and put out gas and gas odor. Second, every time the heater reaches its set amount of time to have the flames on, it shuts down the flames and puts out a lot of gas and gas smell. Extremely large amount of gas odor every time. The smell permeates my entire house. Normal amount of ventilation I used for my old Deerborn heater, that this Mr. Heater is replacing, is not nearly adequate to ventilate the extreme gas odor that this unit puts out. I have increased the amount of ventilation in the room, and this is not enough. I have thoroughly checked the gas line and all connections for leaks, by spraying soapy water on every part, and by getting right up to these places and smelling for gas odor. There is no gas leak from the line or from the connections. It is all due to the heater shutting off the flames over and over.

Works great in my sunroom/greenhouse. I live at 5,700 ft. elevation, and no problems with the oxygen sensor turning it off. All the plants probably help. Nice quality, looks even better than the pictures. Clean blue flame. Keeps the room at 65 degrees even turned well below the first thermostat setting. Easy to DIY, unless you need to run a gas line to it, then I'd hire a pro.

It heats up the basement in a jiffy, for a fraction of the cost of our electric space heater. Installation was really easy. I had the local plumbing/heating company run the gas line for $500. Looks decent, works well.
