I like that these heaters allow for survival within reason. I dislike however that for perhaps 50 years or so no one can engineer any ventless unit that truly burns clean enough with minimal ventilation. No matter what type of heater either, they all emit hydro carbons that can asphyxiate breathing. I think they could clean them but I guess the oil giants don't want people breaking the dependencey realm of residential living.
