I wanted to fit a hot water shower in Matilda, my discovery.
First problem was space!
Matilda has air con, triple charge, charging systems etc, etc..
I overcome this by fabricating a bracket to mount the heat exchanger on the inner wing, as close to the heater pipes as poss, as this is where I plumbed it in to the vehicle...
Once I had the heat exchanger mounted in position, I cut in to the heater flow and return pipes. This would provide hot water through the heat exchanger, whilst the engine was running!
I then installed the nessasery pipe work, using flexi hoses around the engine bay, to alow for movement, and 15mm rigid from front to rear of the vehicle.
COLD
Heat exchanger to a tee, going to back of vehicle ( on board water tank) and to one side of an anti scortch valve ( this valve ensures you don’t get burnt when the water is first turned on ) I also tee’d off to go to a quick release fitting which I mounted on the frount bumper ( enabling me to draw water from another source, bucket, lake ?? and not my holding tank.
I also installed a one way valve in the system, ensuring that lake water??? Could not contaminate my tank.
HOT
Heat exchanger through anti scorch Valve, Teeing off to give me hot water at the taps in the rear of the vehicle. Out the anti scorch valve to a quick release fitting next to the cold one on the bumper.. ( this is where the shower head plugs in..
Extras
15Mtr stretch hose with a shower head attached.
Plugs for bumper mounted quick release valves, so dirt doesn’t get in and block them up.
A pop up shower tent, and job
complete!
Turn on shower, causes a pressure drop, pump cuts in and pumps water from tank to heat exchanger, this in turn warms up the water, sends it to anti scorch valve, where it mixes with cold, and comes out of shower head at desired set temperature...
I am now working on a circulation system, so I can fill water deposit and hold hot water, circulating it through the heat exchanger to keep it hot.. so I won’t have to have the engine running whilst showering.. I’ll let you know how I get on with this.
