This time we're plumbing in our campervan hot water system using the Bobil Vans heat exchanger kit, so we have fast (and cheap!) hot water for our shower!
With this kit we can heat our water using the hot air from our Chinese diesel heater, or from solar using any excess charge once our batteries are topped up. Or just from driving down the road too!
In part 1 we setup the Bobil Air Xchange for a quick trial run, now it's time to get it all connected up to the shower and see how fast it can heat the water...and how cheaply. We spent some time putting it to the test!
Thanks for watching! Any comments or questions? Let us know below!

@nirodper 11 ай бұрын

At max power you're using 400ml/h of diesel so about 15MJ (4.2kW). You're adding 2.3MJ in 18 minutes (7.5MJ/h or 2.1kW of heat). That gives an efficiency of 50%, not bad considering the small heat exchanger and the heat lost in the exhaust. Also you get some heat inside the shower through the vent. For reference a tankless non-condensing gas heater is 80-90% efficient being bulkier, having more complete combustion, with a larger heat exchanger and running all the exhaust through it. Would be nice to compare it to a hydronic system as this seems much cheaper

@SelfBuiltStories 11 ай бұрын

Thanks for the comment! Interesting to look at it from the raw efficiency point of view like that, cheers. Yeah it's a great bit of kit for the size and is more than practical enough for us in the van, and the excess 'wasted' heat is really useful too. In fact just now we've been drying out all our clothes after a walk in this miserable weather, very handy! And yeah that would be a cool comparison 👍

Once again your videos have been amazing. I have the same bobil van setup and I have just got the heating element / solar heating setup. Took me a while to realise that if your not using the diesel heater then you have to drop the air temperature setting down on the display so that air temp relay comes on. Silly me. Took me a day and a half to realise that is what I was missing. Thanks again for your awesome videos. They have massively helped me.

@SelfBuiltStories 6 ай бұрын

You're welcome, glad they helped! Yeah that part was a bit confusing with all the different relays! We actually wired it differently so we can have the element on without the air temperature relay needing being on, for that reason that we might want to use the element without the heater. So our element will come on as long as the second switch and water temperature relay is on which has been working well for us. The only thing is that the circulation pump doesn't come on with it that way so the temperature reading is a bit delayed, might adapt it to have the pump come on as well at some point 😛 Happy New Year! 🥳

@17bArawata 6 ай бұрын

That does make sense now that I think about it. I don't really need the pump on when just the heating element is on, I'm just wasting power there. I like your idea of having the air relay out of the equation in this scenario and the pump off. I actually will change my wiring to do the same. Thanks again. And happy new year to you both and many happy van adventures 😃

Very interesting way to heat water! I was thinking that possibly a good way to heat things in some cases, especially being in Arizona at this time, is the sun. Even places not like Arizona can get a good enough amount of sun for heating. I saw a guy that has a tube about 5 feet long and in Arizona, he'll just lay it next to the camper after filling it with water. Also, I really like bread and would consider baking bread with a solar oven, as well as heating water with solar power. In addition, I wonder if there's a way to transfer solar as heat directly in some way, maybe with mirror concentrating the beams into a window possibly. Maybe put a piece of metal inside the van and it can heat up with the sun heat. Of course, usually solar isn't as powerful in winter when it is needed most for heat.

@SelfBuiltStories 3 ай бұрын

Yeah we've seen things like that, low tech is often best if it works for you. In the UK relying on the sun for hot water would probably mean cold showers most of the year though 😅 We do have an electric element in the tank as well so we can use solar to heat the water with that for free, when the sun does come out! 👍

We've been using the shower (non-recirculating) for a couple of months now, and the thing that forces us to go back to civilisation first is having to find somewhere to offload the grey water. Looking forward to having it recirculating as it'll extend how long we can be off-grid by quite a bit we reckon. But every setup has pros and cons, we have the complexity of building it and the maintenance in keeping it working too 😛

I think it would be good to have a radiator so that the warm water could heat up the van, although a diesel heater does that also. At the very least, if the grey water tank was inside the van so that hot water from the shower can still heat up the van. I saw one van build which used a heated towel dryer as a radiator.

@SelfBuiltStories 7 ай бұрын

Hiya, thanks for the comment 🙂 We actually find the diesel heater really effective to be honest! It's been -5C the last few nights here in the highlands and we have it a toasty 22C in the van 🔥😊 We didn't want the grey tank in the van as it takes up a lot of space, and being under the van it gives the right gravity drop to drain properly and allow easy emptying. Both our tanks are insulated though too so the extra heat benefit would be marginal for us compared to the diesel heater

@pau1phi11ips 11 ай бұрын

Nice, got the same Bobil system but went with using the Victron Cerbo to control the solar water heater. Have a tank level sensor connected to the Cerbo as well as a temp sensor. So when the switch is closed on Digital Input 1 on the Cerbo, there's 50% of the tank full, 90% battery and temp is under 50 degree's it turns Relay 1 on and this is connected to a 60A relay for immersion heater. I thought this would be fine but also added a bypass so I can turn the Bobil pump circulating water though the radiator. Having the water moving when the immersion heater is on makes a big difference.

@SelfBuiltStories 11 ай бұрын

Cheers, yeah it's a cool bit of kit. And that's an interesting way of controlling it, nice one. We'll probably add a cerbo at some point as we have a lot of victron kit and it would be nice to be able to monitor it remotely. And yeah have been thinking of making some wiring changes to be able to have the bobil pump on when the element is running on its own, as with our temperature sensor at the bottom of the tank we found that opening it up and stirring it around it would actually be maybe a few degrees higher than it was showing. Not a big deal but would be a cool upgrade to do to make it even more efficient 😛

@klaasslager8270 11 ай бұрын

Hi, is this possible with the normal Cerbo GX settings, or do you need to install Guimods? I would also like to control my immersion heater the way you do, but i don't know how to program it.

Brilliant job and amazing detailed video...its good to see the results with your testing... to have the patience to film it all and analyse the results so meticulously on top of actually installing it is very impressive. I'm thinking of installing the same system in my van...how long did it take you? And how does the the tank fill up, do you have to do it manually or is it fed from your main cold water tank?

@SelfBuiltStories 10 ай бұрын

Cheers, glad you found it useful, makes filming it all worthwhile 😀 It took us a little while but to be honest most of that is the filming! This project was a nice one difficulty wise as for the most part it's just connecting all the kit together and wiring it up, the tricky part for us was just making it fit into the tight spaces we needed it. And then a bit of time to put it all through it's paces at the end of course. And we fill it from the cold tank at the back of the van. It's a pressurised fill with a manual valve. So we open one valve to drain out the existing water into the waste tank under the van, then open another to refill it from the fresh tank. Takes about 3-4 mins to drain and 2.5 mins to refill 👍

@GenuineVanLife 11 ай бұрын

After watching this install I'm actually happy I didn't get a bobil heater. It takes up a lot of space and all the various things and complicated electronics to think about are pretty crazy. You did an amazing job. Some thought from my side: I know in UK the taps don't mix water for some weird reason, so you put the temperature at 40 degrees. If you'd have a mixing tap and you'd heat the water to 55 degrees and mix it with cold water, won't you be able to get more mixed 40 degree water, so you can have more/longer showers? Also this will help against Legionaire's disease in the tubes.

@SelfBuiltStories 11 ай бұрын

Cheers :) Yeah there is a fair bit of wiring involved with our setup but quite a bit of that is from the optional solar element. We also have the DIY version, they make a pressurised one as well which is more of an all in one unit. And mixer taps are most definitely a thing in the UK! We had to hunt for quite a long time to find a shower tap that _wasn't_ a mixer as we specifically needed that for our setup. Because our shower will be recirculating we will fill it up to the exact volume we need to maintain a continuous loop and then the same water keeps going round. Then we can theoretically shower for as long as we want without using any more water than what we filled the tank with. If we had a mixer then the added cold water would keep lowering the temperature and after a while there would be too much water in the loop so the overflow on the tank would kick in. But yeah our setup is a bit niche because of the recirculating part, I think the only time I've ever used a non-mixer shower in the UK is in our van 😛 Good point about legionaires, to combat that the tank water is taken up to 60-70C every now and then to kill anything off, and the entire tank is also replaced with fresh water from the cold tank after a few showers 👍

Wow what a meticulous incredibly well planned build! How does the water recycler work? Is that a standalone part or have you put it together yourselves? I imagine that's fairly essential for making a 15L water tank be able to supply enough hot water right? Also, what are your plans for heating water in warmer weather? Will the heater still be pumping hot air into the living space? Cheers :) keep up the amazing and inspiring work!

@SelfBuiltStories 2 ай бұрын

Cheers! And yeah we figured to justify having a shower we wanted it recirculating so we didn't have to carry huge amounts of water to actually use it. What we do is have a military style shower first using as little water as possible, usually a couple of litres each, and during that we get clean and then wash away any dirt and soaps etc into the waste tank under the van. Then we switch it to recirculating mode for a nice long rinse afterwards, and that sucks the water out of the drain and pulls it back into the van, puts it through a number of different filters and a UV light and then drops it back into the tank to start another loop. It's a very DIY setup, but using some off-the-shelf water filters. And yep no problems with that, if the heater is being used for the water then the 'waste' air is not actually that hot, just luke warm as a lot of the energy is transferred to the water. And the air goes into the shower as well so it doesn't really heat the van up at all. We've used it during a heat wave and it was fine 🙂

@cccmmm1234 11 ай бұрын

26A is quite a chunk. I am not too surprised that caused a voltage drop on the wires that caused it to kick back out. Maybe consider running for longer at a lower current? Ideally you will be using surplus when the battery is fully charged and you're getting "overflow" power. Heating 1 litre of water 1 degree C takes around 4.5kJ of electricity. So, say, heating 15 litres by 30 degrees will take around 2025kJ = about 1.9 hours at 300W. At 100W (ie. about 8A) it would take 3x that but if the sun is shining that wouldn't be pulling anything out of the battery. Interesting.... lots to consider.

@SelfBuiltStories 11 ай бұрын

Yeah you could do that pretty easily, as you can connect up just one side of the heating element to cut the power in half to 150W. You can also set a time delay before shutting off so a short momentary drop in voltage wouldn't matter. For the first test we did we had the shutoff voltage too high though so lowering it a little and it was fine and we were able to maintain it on for as long as we wanted, so a bit of a balancing act with each setup and also the seasons. In Summer when we can recharge more easily we will probably lower the shutoff voltage and eat into our battery a little bit but in Winter will want to conserve more and only have it trigger at the very top end of our charge cycle. What's cool as well as that as we have our DC-DC charger setup we're also able to heat the water with excess charge from driving. So with those two together we should be able to do a fair chunk of the heating for effectively free and then just top up whatever's left with the diesel kit (and take it up to 70C every now and then to kill off any nasties). Thanks for the comment! 👍🙂

This has to be the best most informative build on KZfaq. Will definitely be taking some ideas. I'm confused by the idea of the recirculating shower (I'm only half way through the video). Are you planning on showering with waste water???? or dirty water from the shower? Forgive me if I'm missing the point.

@SelfBuiltStories 11 ай бұрын

Thanks! And yeah so the way it will work is the water that goes down the drain will be pulled back into the van and passed through a series of filters and UV light before going back into the tank. We'll then use the recirculated water for a few showers before draining it into the waste tank under the van and refilling with fresh water. It'll take a bit of experimentation to find the amount of cycles we can get out of it. We're going to have the modes switchable too, so the first part of a shower can be standard so if we've been out running or hiking then any dirt etc will drain out into the waste tank. Then switch to recirculating for a nice long hot rinse afterwards. That's the idea anyway! 😀

Hey both, loving your videos, thank-you so much for documenting your conversion in such detail! I'm down in Cornwall currently converting my own XLWB Transit, with the goal of full time living while I travel and save some money, and yourselves and Mispronounced Adventures have been invaluable resources. I'm looking to go down the recirculating shower route too, and your solution looks like it will fit perfectly with my layout. I was just wondering how you're going to handle the water from the shower re-entering the tank as it exits through the floor. I might be having a daft moment and missing something really simple, but I was wondering if the pump on the re-circulating shower side will draw the water back into the tank or if you'll need an additional pump/method to get the water to travel back up into the tank? I've skimmed your previous shower videos to see if I missed any of the under van shower plumbing had been done, and couldn't see anything past the hole and drain being added, so If this is going to be covered in a future video then I look forward to learning! Again thank-you for the great content and best of luck on your journey!

Hey! 👋 Awesome, we love Cornwall! Glad you're enjoying the videos and yeah Alex has some great videos on his channel 🙂 Cool yeah we figured it would justify having our shower more without having to carry a huge amount of water for it. You haven't missed anything though, right now it just goes through the drain in the floor and then flows into our waste tank under the van. We figured we'd do it the normal way first so we can start using it and then add the recirculating part afterwards, and yeah we have a separate pump for that. So there's one pump for the cold water, one for the hot water, and one for the recirculating. It will take the water after it's gone down the drain and pull it back into the van, through the filters, and then back into the tank. Similar to the setup Alex has but with the difference that he has it all inside the van with a raised shower tray and we have ours going through the floor where it connects up with our other waste plumbing under the van. Thanks for the comment and hope your build is going well 👍

I'm trying to evaluate different water heating systems currently so this video is quite helpful, but I see one potential flaw in your design that I'm concerned about avoiding in my system. I see no way to quickly drain all the water. In the colder parts of the winter I consider this to be essential. I don't know whether the heat exchanger can be inverted with the water connections on the bottom to make it gravity drain or not, but if I did your system I would consider that important. Also, what is the heating capacity of your diesel heater? That would be useful to know. Thanks.

Hiya, there is a drain at the bottom of the heat exchanger with a manual tap, you can see us attach it here: kzfaq.info/get/bejne/sM2Rhc-evt-woJ8.htmlsi=0RfyQKukvfCk20cq&t=1274. We also have a drain tap we added on the tank, so we open both of them when we want to drain it out, which we do fairly regularly every time we want to refresh the water for our shower loop. We timed how long it takes to drain in different scenarios and you can just see some of the results in the bottom right of the results here (kzfaq.info/get/bejne/itGUiNebmtyXlaM.htmlsi=XLWx1OZzspo7nxeO&t=1410).

You’ve made it all so incredibly complicated, are you not worried about one (or more) of the hundreds of connections - both electrical and hydraulic - might fail once the van starts rattling over some beautiful Scandinavian backroads? 2. Isn’t it about time that you went out and explored some beautiful Scandinavian backroads in your van? Just get it finished (enough) to be liveable and add those “extras” over the years. A “hotel” light switch? Really? In a space where - if you’d placed a standard switch halfway between the door and your bed - you could reach across, from either spot, and turn it on or off. Get it done and get out there! Don’t get me wrong - it’s a fabulous machine - but is that really all the point of it all is?

Being able to dim the lights for a movie night, turn on the lights by the door coming back to the van late, or switch on the kitchen from the bed if one of us gets up earlier etc. A luxury for sure but as it's our home well worth it for us.

I cant see any fodder for my usual smart arse quips in this episode 😕. But if I put my picky picky hat on I would have had a direct shower vent to outside and a bigger water supply tank over recirculating the shower water which even though I understand what we are told about UV purifying it still makes me wonder about washing my face in recirculated soapy Bum crack run off. .

There are two huge issues if you want long showers with non-recirculating: the amount of water you're using and the amount of energy you're using. Their whole battery is 200Ah @ about 12V. That is about enough to heat 64 litres of water and do nothing more. At 5 litres a minute that would be 12 minutes of showering then no more electricity. The other option is shorter showers/wipe downs which this couple don't want. Me? I'd go for the shorter shower, but it isn't my choice to make.

Haha cheers 😛 That is a good point, no one wants that... for that reason we're having it with two modes. So you can use the normal mode first to get clean and drain to the grey tank, then switch to recirculating for the long hot rinse afterwards 😏We figured to justify the space, complexity and weight of water we need to carry for a shower we wanted it to be recirculate so we can actually use it all the time and make it worth its while 😁

@@cccmmm1234 Yeah our pump can actually deliver 7.5l a minute so we'd drain it out in no time! We could have gone with water saving heads but knowing we were going to build it recirculating decided to go for a higher pressure as we plan to use it in that mode most of the time but we can still do a military style shower if we want. We won't use battery power to heat the water unless we're desperate though, we'll use the standard bobil heat exchangers and then the excess power from driving and sun hopefully

@@SelfBuiltStories again I am being picky i imagine the heater will not keep up with flow rate and you might get 2 tanks worth before you have to stop and replenish the heat lost. 1st world problems ehh. anyway none of this detracts from the top job you are doing.
