I recently bought a portable space furnace after hearing how powerful today’s furnaces are, and I have to say that I was not impressed with the one I bought, but it was not that good at all! Sure it did the job and heated the space I had it in, but I was not impressed by how it kept turning off no matter where I set the temperature control on it. I am not sure if maybe I bought a defective one and I need to return it to the store or what? I may have to go online and do some research on this space gas furnace and see if this is an issue with all of them or just the one that I bought. If I find that this space furnace is really defective I will return the portable furnace to the store that I bought it from and get an exchange. I still have the receipt so it should not be a problem at all, but if there aren’t any defects and this portable furnace just does this as a part of its regular working , after that I will still return it and just not buy this brand of portable space gas furnace ever again! Like I said, I am not impressed by how this temperature control keeps going on and off on the portable space heater! There has got to be something wrong though. Because otherwise there would not be all the hype about portable space gas furnaces today if they were all messed up like the one I bought is.
