Outdoor wood boiler, ready to unload. Mel uses his bobcat to set it into place. At the front of the bobcat is the water line in black, plastic pipe.
There are two water lines within the black pipe. Incoming in red, and outgoing in blue. The hot water continually circulates via a pump. The water lines are also covered in insulation within the black pipe. It was a real pain to drill through the basement wall.
The water pump is on the left. Bottom center is the fan, which kicks in when the temperature of the water decreases to a certain level. I can adjust the temperature of the water. Right now, the fan shuts off when the water temperature reaches 145 degrees F.
