They definitely work and will keep a midsize room warmer then your home Thermostat setting.
But you have to realize that they are NOT instant heaters. They will slowly and gradually warm up a room. I’ve put them in my upstairs bedrooms which allows me not to run the home furnace as much.
So my estimate is that each unit is costing me between $15-$20 / month x 4 = $60-$80 higher electric bill.
Is that better than increasing my gas furnace. IDK
Good question for someone smarter than me .”
