Purchased the mr. heater 45k btu from my local lowes store on sale. Took about 3 hours between unpacking and converting over to propane with the conversion kit, installing the vent pipe etc. until we had it up and running. Puts out good heat, quiet and works every time. I would recommend getting a digital electronic thermostat as they seem to be more accurate than the mechanical style.

Heats OK if you can get it started. Seems company is having problems with a cold soak issue on their P.C. board, so they tell me. It takes about 10 minutes to get it going if you have turned it off and try to start it "cold". Mr Heater is suppose to come out with a new board to fix the problem next year. Also draft fan motor tends to have excessive vibration and make a considerable amount of noise.

I purchased this heater from Northern after reading some reviews here and there. Several reviews noted poor packaging and damage upon arrival. I wasn't disappointed. There were a few dents and bent parts but nothing to warrant a return. My biggest complaint about the heater is that the blower behind the unit for heating the room vibrates alot. If you walk into the room you can actually feel it as it resonates in the room. I'm guessing the fan blade is out of balance. It made the unit vibrate enough to make the whole office hum. I did see another reviewer post something about the heater vibrating badly. I replaced the bolts for the cage that protects the fan and holds the motor with some vibration isolators which quieted it down considerably. Sad that I had to fix a new machine. I'm going to call and see if I can get a new blade sent as that will be much easier than taking the whole unit down and sending it back. Other than that the unit operates great and heats the room up quickly.
