I guess the cabin heater has to be set at "open", ie "hot" for your system to work - so that the hot engine coolant circulates through the cabin heater...? Also, am I right that if you develop a leak in your hot water system and your cabin heater is set at "cold", ie closed, you would loose much engine coolant. So it's a brassica safety mechanism?
Thanks for the explanation and for including the information about auxiliary coolant heaters and mixing valve. I hope that you don't need this advice from me but I would put caps on the quick-connect fittings so that you don't pick up debris or dry out the O-rings.
Hey, I’m happy it helps! No, I don’t cover it. You are right I probably should, but it is still a temporary design (since 5 years). I want it to be connected to the water system and I don’t want to open the bonnet to shower… but I haven’t come up with a better place to connect the showers head…
It was a struggle!! Hahaha I was so tired and couldn't talk two sentences in a row. But it was funny in the end. One shouldn't take oneself too seriously 🤣
Great informative mechanic water system . Thanks again for sharing your wonderful journey with us your over landing friends. Cheers from Steve Stott in Sutherlin Oregon U.S.A. :) :) 🛠🍻👍🏼😁
Hello, I just had to say how how much I enjoy watching your youtube show. I go on desert expaditions with Popski's private expadtions. As such I'm always looking for better ways to prepare my TD5 110 2004 Station Wagon for the heat of the desert and a re-mapped ECU. Your heat exchanger is exactly what I need to keep the engine tempiture down, while struggling with soft sand dunes and altitude. Such as the Atlas Mountains later this year. I would need a more basic version than yours, with the sole purpous of cooling the engine, Can you help me design one please? I also like that you cover all your maintainance issues, most similar youtubers don't show this kind of content. Your tool selection video was the best I've seen and highly recomended it to people interested in buying a Defender for expaditions. Keep up the amazing work!
Hey Tony, sorry for the late replay. I’m surprised you feel the need of more cooling. I don’t have much experience with chipped defenders yet, but doesn’t matter what we do our engine always stayed cool. Even in Iran with over 50 degrees during the day. If you really need it you could use the heat exchanger get a electric coolant pump and a second radiator. Connect it all to a second cooling circuit. In my car I’m way more concerned with gearbox and transfer case temperatures than with engine temperature. That’s why we added a transmission cooler. This is more for highway driving but still an important part. If you need More information you can reach out to us via email: Contact.thebluelandy@gmail.com Enjoy Morocco
Really worth the work and money, in the future I want to find a solution to not connect everything in the engine bay to not open the bonnet all the time, always something to do 😂
Happy to share! It took us a bit of time to record it, but finally the video is here, even though we were close to cancel it that day due to the insane traffic around us.
This is great practical engineering! How about the pump? Is there a pass through valve or what happens when the engine pumps is being driven by engine?
Thanks, I believe the pump is just spinning driven by the engine. Sometimes I use it in combination with the heater to boost the flow and heat up the cabin faster. I having the heat exchanger and the pump in series of the heater causes a bit higher resistance in the small coolant circle. If that is a concern you could start the pump with ignition…
@@Thebluelandy it could be done with two simple check valves and putting it in series with the other water line. Then you make sure there is no issue with the pump seizing or anything else.
Thanks for the great video. How do you determine what size fittings to get on the heat exchanger, 1/2", 3/4", 1" ? And weather to get male or female fitting?
Hey Steve, I took the heat exchanger, went to the hardware store and tried to assembled a solution that could fit 🤷. In my case the heat exchanger came with ¾“ and 1“ male connectors. That was the only option.
If I ever get in a plane accident or ship wreck and end up in the jungle or remote island then I'd like to have Kai with me to survive. Thanks for the teaching
Hey Michael, the heat exchanger is in series (after) the cabin heater. In TD5 Coolent flows from engine to the thermostat (if open) to the radiator, (if closed) to cabin heater, fuel cooler, shower heat exchanger, and back in to the engine
Hay Antoine, so far no. Normally the water evaporates while driving. I can believe it could be freezing if you shower and then the water freezes overnight. Didn’t ran into that yet
Hey Frank, sorry for the bad Link. It’s a plate heat exchanger with 20 plates. It’s made of stainless steel and is rated for up to 20 bar. Search for: “stainless steel heat exchanger 20 plates” I got good results. If not let me know.
He gets this comment all the time. I have the feeling he has less and less motivation to do it, as people keep on insisting him to shave (including me 😜)
Depends, if it’s hot outside 3-4h if it’s cold you better shower quick after driving. Just check how long your engine feels hot after driving. It’s a big block of steel it takes a while to cool down.
@@Thebluelandy when you say to build it in after the auxiliary heating, how this works? Because a Webasto or Autotherm doesn‘t work with the motor coolant - or do I understand anything wrong😅
I believe You are just referring to the air heater like a Autotherm 2d but both companies also sell water (coolant) heater (e.g. Autotherm flow 5D) . Those are made to heat up the engine (and through the engine the car) in winter. Where those get installed is the place where you want to put the heat exchanger.
Thanks for sharing your system. Which heat exchanger did you use? The amazon link gave a number of different exchangers. Was it a 10, 20, 30, or 40 plate exchanger?
I have to admit if we find a way to turn this low temperature heat into useful engine, eg electricity. We would be able to cover most of humanity’s power needs. This is why this low temperature heat flow (eg. From power plants, or engines is only used for heating.
And electrician! And many more things 😱 pretty smart yeah . We got stuck the other day going up a volcano in Argentina... You will see that in a month or so, it was tough. But we enjoyed our Friday thanks! Hope you did as well! Greetings from snowy Argentina
What do you think about this system? If you have any questions, let us know in the comments! 👇

Honest, I think about to copy it and install it on my TD4. Is your a TD4 too, so that you can let me know where it’s exactly situated? Thanks Joe

This is very nice. You just gave me an idea for my Toyota Dyna 4x4
It’s such a reward, and so worth to put in the work! Good luck with the project! Send us some pictures on Instagram when it’s done!
Nice. Very informative.

I always say the same! Zombie apocalypse, I better be next to Kai to survive. 😱✌️
Was für eine tolle Konstruktion.
Wenn ich es richtig verstanden habe duscht ihr solange der Motor noch genug Abwärme hergibt ?
Ja wir duschen immer nach dem fahren wenn der Motor warm ist. Wenn man eine Wasser Standheizung hat kann man auch ohne zu fahren warm duschen.
Clever system. Is it also connected to the hose carrying coolant from the radiator which flows to the vehicle's heater?
Hey Michael, the heat exchanger is in series (after) the cabin heater. In TD5 Coolent flows from engine to the thermostat (if open) to the radiator, (if closed) to cabin heater, fuel cooler, shower heat exchanger, and back in to the engine
Nice and simple ! Any issues in freezing temperatures with shower water trapped in the exchanger ?
Hay Antoine, so far no. Normally the water evaporates while driving. I can believe it could be freezing if you shower and then the water freezes overnight. Didn’t ran into that yet
That's cool, I mean hot ;-) The link to the heat exchanger doesn't work for me, maybe you have a type or name?
Hey Frank, sorry for the bad Link.
It’s a plate heat exchanger with 20 plates. It’s made of stainless steel and is rated for up to 20 bar.

Hi Kai, great to see you are both able to have a hot shower on the road. Maybe a shave too! 🤣
He gets this comment all the time. I have the feeling he has less and less motivation to do it, as people keep on insisting him to shave (including me 😜)
Hei there!
How long after you stop driving there‘s still warm water available? :-)
Depends, if it’s hot outside 3-4h if it’s cold you better shower quick after driving. Just check how long your engine feels hot after driving. It’s a big block of steel it takes a while to cool down.

Hey, sorry for the confusion, we’ll try to fix that the next days.
We have the 20 plate version.
very interesting, would be great if you could convert all that heat energy from the engine into electricity and store it in battery's.
I have to admit if we find a way to turn this low temperature heat into useful engine, eg electricity. We would be able to cover most of humanity’s power needs. This is why this low temperature heat flow (eg. From power plants, or engines is only used for heating.
Wow plumber and mechanic......
Pretty smart guy
...I missed how you guys got unstuck....I know you had a plan
It's Friday be safe have fun
