Spring is officially here! Which means, warmer weather and much longer days and nights on the bus.

Following our spray foam insulation last month, we’ve accomplished a lot these past couple of weeks. We laid down the floor insulation, finished our radiant floor install, made the inside water tank stand, and finished the fabrication and welding process for the roof deck and solar panel supports.

The radiant heat floor is an interesting and more unheard of concept in the “School Bus Conversion” world. We chose radiant heating as not only an extra source of heat, but because of it’s energy-efficient and quiet nature. We installed hydronic heating coils through custom-made channels in our floor. Then, we laid plywood over the top of them. Once we’re done, the heated water will travel through the system to heat the bus from the ground up.

Our solar panel and roof deck rack has also been something we were proud to accomplish this month. We fabricated the rack to mount and tilt the solar panels. The tilt will allow for extra solar collection during the winter months. Each side will be on its own solar charge controller to collect energy independent of one another. In the center portion of the solar rack, we will have a narrow walkway that will allow us to easily clean and move snow off the solar panels during the winter months. We have a total of 1420 watts of solar.

David fabricated the entire solar rack, included the tilted one that is operated via linear actuators and a wireless remote. We also decided to use this extra feature as a lid to store extra ‘toys’ (aka snowboarding, surfing, and skimming gear) underneath.

Getting this thing on the bus was a PAIN. It was heavy. Once on the bus, we had to secure it / weld it onto the side supports.

The first piece of foam insulation for the floor is in!

We built a jig for the router to create the channels in the floor for the pex.

We’re laying out where the heat channels will get placed. We did have to cut some of these to size and shave out some of the panels using a blade, but overall they feet really well into the insulation.

We put a heating loop into the back under our bed and water tank. It will help prevent the 85-gallon water tank from freezing.

The foil tape was implemented to further insulate the floor and seal up any air gaps.

Once we finished the radiant flooring, we put down our 5/8inch plywood. Cutting around the engine box and stairs was the most difficult! We did our best to leave as few seams as possible.

To glue the floor down, we used construction adhesive and then placed cinder blocks that we purchased from Home Depot on top to allow it to set for about 48 hours. Pro Tip: Just return the cinder blocks after you’re done with the plywood floor installation. They have the most flexible returns and you’re likely not to ever need that many cinder blocks again!
