purchased heater to take the chill out of the basement from time to time. It does a good job, had to have an electrician install a 240 plug, and I do notice a substantial increase in my electric bill if I run it for any length of time. But nothing is cheap in this world we live in, and if you want comfort, you must be prepared to pay for it. I would recommend the heater. My son and my electrician both have this heater...............
