Adding heat to the 3 season room.

When it got cold this year, we lost the use of the 3 season room. Over the past week I installed heat in the room. The heat consists of 2 powered heaters that fit between the floor supports in the basement and blow heated air into the room. These heaters normally go under kitchen cabinets. My heating contractor wanted me to use these heaters in this room, if the room is unused for a length of time, the heating pipes would not freeze. This project requires woodworking, plumbing, and electrical work. I get to use all of my tools.
