Thumbs up Interesting video - Diesel heater EGR cooler thermosiphon

Looks like an alternative for a 12v water heater..

Well I have to say, I'm surprised there's no interest in this.

I was planning on doing the same, but a brand new Espar H5 Hydronic unit has popped up locally fir just 350, so buying this now for my hot water needs.

This guy has the first Chinese water heater which is similar to the air heater, but Hydronic. Looking forward to his findings with it, here's the underside of the unit..

I will be curious what you find. If the heat exchanger is aluminum, you will likely need a coolant loop, as raw water will corrode the aluminum. Though you could have the unit anodized to make it resistant enough to corrosion for using raw water.

I started a thread about his unit over here.

Im very interested in this.

Need to heat up the van on those chilly mornings, better yet want a solid option to heat water for warm showers that won't deplete my battery off the inverter.

I just installed a chinese 10A 12V regulator from amazon in the rear pillar for the maxxfan and lighter sockets which power the dometic cooler. What would be a good product to step up 12v-24v for this heater application?
