In these cases a portable space heater is not needed to keep your feet warm, which is this little furnace’s typical use
Some HVAC units are not worth your time or effort. Window air conditioners, for instance, are full of trouble. First of all, window air conditioners are loud. It sounds like you live in the middle of an intersection in the city when you run a window air conditioner! Second, they do not cool all of your house. Window air conditioners really can only keep one room in your house cool at a time. Central air conditioners are the way to go because you can hardly hear them and central air conditioners cool your entire house, well, anywhere that your air ducts lead to that is. The next useless HVAC unit is a portable space heater. Portable space heaters are old and outdated. In today’s modern world of HVAC a person has air ducts come up through the floor which are connected to the furnace and this is enough to keep their feet warm. Many people also use heated flooring which is connected to their main heater. In these cases a portable space heater is not needed to keep your feet warm, which is this little furnace’s typical use. While one might argue that you can use a portable space heater to heat a single room, I would argue that there are much better furnaces and heaters in the heating and cooling business these days that will work much better than an old portable space heater. While the dislike for window air conditioners and portable space heaters is a personal opinion, I believe that many people in the HVAC world hold the same opinion.
