1st heater of this kind died after about 4 years of use. I like this side mounted style better than the over under of the previous heater. Heats my shop (1000sq ft) quite well. Used its predecessor to heat two large (14ft diameter) tents down to comfortable temps when the outside temp was near freezing. I like that its quiet, the fire is OUTSIDE the tent/shop and that it will run a full 12 hr on anything below 4/6 power. Software controller could be better, and the remote could have thermostatic control, but its way better than a Mr Heater in the tent/shop. Just wish they made a propane version.
