I was driving past a house under construction and saw this device in its driveway. It was operating, making a continual noise. Does anyone know what this machine is and what it does?

It looks like a fan-forced portable furnace, to blow warmed air into the cold building that is being built.

  • Would this be called a mobile indirect fired air heater? The purpose is to have all combustion gasses exhausted out side while a heat exchanger warms the air delivered to the inside through the flex duct. I would never have known they existed with out your answer.

  • @Kris It's definitely a mobile air heater, can't say about the rest of your description.
