I originally got this heater for my sewing workshop in my chilly, uninsulated basement. However soon after I received it, we got a cold snap (low temps of -20F at night at highs of 15F during the day) and it's been running 24/7 in the laundry room which is attached to my kitchen and has no door between. The cold air leaking into the house through the dryer vent was chilling the kitchen and creeping into the rest of our open-concept house. I like that the controls are simple, no electronics or digital thermostats to fuss with. I keep it on Low mode, with the temperature dial in the middle and it keeps our little laundry room quite toasty and helps the kitchen feel warmer as well! I'm going to order another one for my basement workshop because I've been so happy with how efficiently this heater works.It is silent after the initial warm up period during which there's some pops and crackles as the oil gets hot. It takes a little while to start putting out heat but once it does, it's very consistent and doesn't dry out the air.The benefit of this type of heater is, because it doesn't blow hot air, it's great for a workshop where you don't want things blowing around from a fan-type heater.The only concern I have with this type of heater is the whole thing gets quite hot to the touch, so keep it out of reach of small children and pets. I keep our dog away from it with a baby gate across the door way to the laundry room. If you need to move it after it's been running for a while, you need to let it cool down or use pot holders.I was concerned about damage during shipping after reading some of the reviews, but my unit was well packaged and did not have any dents or bent sections.
