Thread: Hot water system / heat exchanger shower

I like this

H2OT - Roof top, pressurized, solar heated shower/sprayer using ABS pipe - YouTube

All the best

For single vehicle camping I use one of these, these little pumps are amazing, far far better than those cheap 12v primus/companion shower thingys AND they last 20 times longer.

Yes, we've had one for ages and it is still working fine. I just can't justify the cost of the other units.

I had a chat with the bloke from Dieselheat at the Sydney caravan and camping show. he uses chinese made copies of the eberspacher unit, and says they are very reliable and better than webasto. They also carry all parts, but haven't had failure with one. I was looking at a space heating unit for our camper trailer. the prices seem reasonable to me. The water heating unit they make up is about 4 times the size of a space heater.

Hey guys, new to the forum. G'day.

I had a Glind in my Prado 150 and was told the coolant would not get hot enough but it worked well. I would recirculate the water into a jerry can for 5 minutes while running the motor at high idle. This was the recommendation from the Glind guy.

I want to fit it to my new D4 and am hoping it is the same situation. However I cannot work out which of the hoses heading to the firewall to tap into. Does anyone know?

Cheers, Chris.

Completely different cooling system to the Prado, for one you can't sustain a high idle in the D4 unless someone does it with their foot on the throttle and as I said on page one of this thread, the cooling system doesn't maintain a constant flow of hot coolant for long enough.

No ones been able to do it so far, so if you get it to work there will be a lot of guys here wanting to do their D4.

Oh and welcome to the forum.

Welcome to the forum.. Redback has nailed it...

I’d also be very wary introducing Another metal into your cooling system!

Those Glind style showers are a good thing, except for the idling under no load issue.
I’d be very concerned longevity wise on idling for 30 min to just warm some water. It’s never good to have any engine just idling - it glazes bores, makes rings stick etc. this may not be a concern depending how long you want your vehicle or how hard you run it otherwise but worth consideration.

If you have rear AC you could look at plumbing it under vehicle.

Thanks for the replies.

In the prado I did have to hold the revs at around 1500rpm with a rock or stick, I would also run the heater on full heat with no fan to get the flow through the heater element. It only took 5 minutes to heat a 20lt jerry can.

I like the idea of tapping into the rear AC plumbing. That might be a hell of a lot easier to do. Now to find the piping! Always up for a challenge.

There was a guy on the D3 UK forum who got Ayres Automotive to fit one for him.
