So my wife and I bought one of these about a month ago. It worked well for a few days and when the colder weather began to hit, it struggled. It still runs well, but we were trying to use it to replace or completely abandon our OIL furnace. It DOES NOT HEAT 1000 sq. feet (because I live in a 1000 sq. foot home.) It will heat a couple hundred sq. feet in a small room. We are currently using it in our office and it seems to be doing the job. Eventually we will need to buy more heater(s) but are not prepared to go with Edenpure. This heater is good for heat, but is not worth the crazy price.Don't trust Bob Vila or the guy from Home Improvement!
