I decided the best way to heat water for the shower would be to use latent heat from the engine, so these pipes need to run the full length of the van. These connect from the thermostsatic valve to a heat exchanger fixed to the engine bulkhead. Yep, you guessed it, got it from ebay. I threaded the insulation-covered pipes through the chassis members as you can see and tied them in place with cable ties. It’s important to ensure that the pipes don’t rub up against anything sharp or hot as you’ll have a leak to sort out..
