Installed the Espar diesel boiler onto the truck and plumbed the heaters and calorifier. It took longer than expected and was a slow go.
It is hooked up to the truck coolant system providing heat and hot water while the truck is running and making it so the Espar can pre-heat the engine if for some crazy reason we are somewhere really cold! And obviously the Espar boiler flows coolant through all the heaters and calorifier
This is the manifold I made to switch the coolant flow to bypass the camper fixtures and return back to the engine, the aluminum bar has slots in it to just the right length to prevent both valves from being closed at the same time.
Espar mounted off a lateral deck support, I had made a box for it a while back to practice some welding but it was way too big so it was cut down and re done.
Fuel line tap into the main tank, would it be normal to have an inline fuel filter in this line? the plastic line has an ID diameter of less than a millimeter!
Manifold mounted behind the air cleaner, the valves are in the position to have full coolant flow through the camper.
All the hose is wrapped, from the Espar rearward I used a neoprene type of exterior wrap I found at home depot, at the front I still have the very porous foam wrap and will most likely swap it out for the neoprene stuff. These are the hose runs that go up into the sliding BBQ area.
Here they are, ball valves are to regulate the flow between the fixtures, the calorifier being the highest point in the system needs the most flow.
Box lid shortened and ready to go on.
Espar seven day timer, I still have the challenge of wiring up a thermostat with it.
The Espar is wired to run off the camper batteries, its wired to a bus bar inside the camper with a fuse at the bus bar.
Tested and runs well, sounds a bit like a jet taking off in high mode but quiets down in low, with the heater fans on the camper heats up pretty fast but not sure about the water heater yet. Lid on and mostly finished.
