Of water and the spirit (making overland camper water tanks)

The making of an overland camper water tank: we have been doing a little series of blog entries about nomadic fire and water, the titles of which we borrowed from the name of that great book.

This one is going to be about how to make a hot water system to run from the engine of the truck, to heat up the drinking water. The main problem with having water tanks on living trucks is that if you have them outside they freeze in the winter, and as we tend to be journeying through some cold fronts for some reason, and as we always end up having serious snow in winter, we decided that this time around we will have a heated water tank. It means we can de-ice the tank very quickly so we can use it in deep cold, but also that if we run the system whilst driving we can have a very hot shower the other side.

Again like in the stove design we have shared this is my personal design, but it is an adaptation from a pattern taught to me by a fellow nomad that has spent considerable time building live-in trucks.

Stainless steel water tank

The first step is to find or make a suitable tank, stainless steel of course is best. Next you need to make a hole at the bottom and drive a stainless steel pipe or coil (preferred) this must be welded shut so it is not open and the water running through it does not interact with the drinking water.

At the end of the pipe there are connectors for the water pipes, so if you are still unclear, the water running through this new pipe is the radiator water so it is not drinking water and should never mix with the tank water, next step is to make brackets on your truck.

Put the tank in, and connect the pipes.

Next and last thing is to split the radiator pipes in two places (you can use the heater pipes) and run them to the the tanks. Make sure to put valves in the pipes so you can shut them off, because you don’t always want to be boiling your drinking water, nor even heat it in those hot summery days.
