They say too much of a great thing is bad, however this certainly is true; Especially when it comes to heating and air conditioning, I had this issue with a portable space oil furnace that I had purchased. Back when, I remember portable space gas furnaces to be pretty weak and just enough to take the chill out of a room. These new portable space gas furnaces do not act like that at all. As a matter of fact they are way too powerful if you ask me! I had the portable space furnace I purchased in our kitchen to keep me boiling while I was sleeping. A way to save money on running the central heating system. Well, I woke up feeling like I was going to die! It must have been over 100 degrees in the kitchen! This was with the portable space oil furnace being on the lowest setting. I can not tell you how this shocked me. I ended up having to open up a window and let the cold frigid outside air come into the kitchen for about 10 minutes to even somewhat cool it off enough for me to be in there. I returned the portable space furnace to the store and told them that it worked too well and that I could not deal with risking giving myself a heat stroke. The store refunded me plus decided to report this to the contractor that made the portable space oil furnace that I purchased. They need to make some adjustments before shipping out any more of these portable space gas furnaces for sale. They could be deadly if one doesn’t think this could happen!
