Mark was talking the other afternoon about the old portable space heaters and the new and modern portable space heaters. And he must say that the old portable space heaters were huge. They were not so portable the way he remembered them. Mark has this memory of having one in the family shower room growing up that was used to warm the space when he took showers. And if Mark wanted to move that thing it was not a straightforward thing like how portable space heaters are today. Back then they were a hard metal type made and so heavy. Mark remembers having to move that portable or so called portable space heating system with his bare hands. When he got it to where it needed to be moved to he felt like he just had come from lifting weights. Mark would not describe that as a portable space heating system at all. While today with portable space heaters they are made of heat resistant plastic, are in fact light and are about the same size as a little blender. Not to mention the portable space heaters of today function better than the portable space heaters of yesteryears. This just goes to show how HVAC technology has changed over the last few decades. Mark does not miss the old portable space heaters one bit and he is super satisfied that today he has the portable space heaters that he does. They are so much better and easily portable space heaters. Mark wonders if they will get even better?
