Congratulations on getting the Vario , if i was going to convert a van it would be a Lwb 4 wheel drive Vario but I'm not sure about the headroom because I am 6 foot 5 inches tall, that's why I live in my 1967 GM TDH-4519 city transit bus. I would really consider building a insulated stainless steel box for that water tank, to protect it and insulate it
Thank you for the advice I’m certainly going to look at building something around it to protect it or if I end up with enough room under the seat that’s going to be directly above it I may just move it to the inside of the van. Stay safe and have a great day thanks for the positive thoughts 👍🤓👍
Just a bit of ally sheet as an angled deflector plate on the front end of that calorifier will do wonders for the life of the connections coming out of it.
There is a weird dichotomy between having SOME redundancy in a system.. and the realization that each redundant system adds complication that might be a liability itself when traveling to remote places. A “Bush” or “Bodger” fix might need to bypass all the redundant addons. Personally, I rarely have travelled to someplace so isolated that a simple repair wasn’t possible .. but I have seen someone else stranded by the high-tech in their vehicle.. modern Sprinters, Transits.. BMW and KTM adventure bikes have that issue as well. In North America, the salt used for ice control is very corrosive to everything under a vehicle .. it gets everywhere as a fine vapor. It will damage Everything installed on the undercarriage. So my calorifier is an Isotemp installed inside the living space. I did find this video to be interesting, informative and entertaining.. Good on you!
The amount I have learnt through your channel is crazy. Thanks Mel for all the videos you do. I’ve managed to convert my own van and gone full time all thanks to you. 👍🏻 if I ever see you about the beers will be on me 👍🏻
@@BigVanSmallWorld I’m hoping to make the van life festival. If I do I would love to show you round and how you inspired me. Great stuff your videos are and they make more of an impact than you realise. Be great to have a beer 👍🏻
What about making a sump guard type thing that attaches to the rails with a sloping upwards part to protect the front of the water heater that has all the gubbins attached?
I would seriously consider the practicality of having the calorifier underneath the van - the airflow over the unit when mobile will increase heat loss considerably - more importantly it will be nigh on impossible to winterise the installation. Given the space you have I would find room to have what is a great resource, protected within the vehicle.
@@BigVanSmallWorld It does get cold in Southern Europe too ! - If I was you , and I'm not - I would drop an insulated " well " into the floor and fit the calorifier into that. Given the nature of the floor construction in the Vario this shouldn't be too difficult - it would be a shame to limit your horizons just to warmer areas.
@@zack9633 A flask of hot water stays warmer for longer outside if wrapped in a woollen jumper (ex site worker) so for efficiency reasons Frazer is correct. In your situation though, you may not be so concerned about efficiency but still...'Every little helps' 💪🐕🚐👊
Very entertaining and informative Mel. I would be cable tieing those spare pipes under the bonnet. They are one of those things that you know you kept but when the stress is high you’ll be searching high and low for them. After all that is one seriously spacious engine bay.
Interesting. If I ever do another van I'd definitely have the pre-heater as I quite fancy doing an arctic trip eventually but I never considered adding a calorifier to take advantage of that loop and have hot water. Hmm.
That is a good idea to include the pre-heater within the system in case you visit Scandinavia etc. What are the additional connections on the calorifier? Are they for a secondary heating element that you could take into the van and create a heated floor with?
Mel, may I ask what you do/did for a living? You are extremely thorough and knowledgeable. You explain everything with such ease and clarity making it all so understandable! When I watch other van build channels after a couple of minutes, my brain goes "ping!" And switches off, then all I hear after that is "blah, blah, blah!!"...😂
Thank you for the compliment really appreciated. I have worked in mainly engineering and mechanics all my life even had my own injection moulding company once 🤓👍
@@BigVanSmallWorld Ahh! Thought it must have been something along those lines!! The other half's tools of the trade are a hammer and a bag of swear words!! 🤣

Mel, far from me to think I have a better idea than you, but have you considered using a second nut to lock those holding the calorifier? I'd hate to see your calorifier on the middle of lane 1 of the M5 🤣🤣 Also, I did need to go for a pee during your draining of the coolant. Us old geezers..... 😇

Absolutely brilliant mate can I be the one to say can you make a sort of mudguard over the pipes on the end of the unit underneath so stones and rocks don't fly up and smash the plastic parts
One thing is for sure, Mel, if ever I needed to fit a system like yours, you provided the perfect instruction video to follow to do it. Good job and great video. Much respect 🙏- Kenny
That looks a brilliant system Mel. As you said. Why don't other van builders use them. Only apprehensiv I would have with putting all that in your van. It is very old. Very old
Hi mate just a thought, external pipe installation would have been better, we use it on boilers . See how it goes . Top install what you’ve done there 👍🏻
Hi Mel, fairplay that's a great job, all bases covered for hot water,... just thinking, and apologies if you had in mind already but you could probably box the caloifier in with some alu or stainless sheet to shield valves and connbox from grit and salt spray from road, also autoterm do some silicone coated heatshield for 24mm exhaust pipe, for engine bay and boats, slips over the pipe like sock, works very well, Bobils prob have it.
Great video wonderfully explained. You showing how to do something I never knew was possible in a vehicle. I was a heating engineer in years past and was involved in connecting large "domestic" hot water systems to waste heat generated by freezer systems in large plant rooms in supermarkets, one hot water cylinder preheating a second cylinder. It worked really well lifting the temperature from around 15 degrees to around 45 degrees with huge savings on the amount of gas used to heat a cylinder from cold. However...the down side was a cylinder of preheated mainly warm water was a haven for bacteria, not something you need to worry about here with your indirect dual systems. Can't wait for the next episode.
I have a 50 litre example. in my house, fitted it into a cupboard then packed it with a quilt. You will find it will not keep the water temp for that long especially open to the wind. However they are the only cheap option for hot water but as good a target as a catalytic converter to scum bags...
Excellent video. I like the introduction of the engine pre heater. might get one of these. the link for the heater shows a different one, I was just wondering what the extra two pipe fittings are (10 and 2 o'clock orientation, I had a 15 litre calorifier in my last van, it was enough to shower two people easy. you will have plenty of free hot water, I also found out that using the engine cooling system while driving to heat the water is much faster than 12 volts and 240 volts elements. Thank you
Hi Zack that’s great to know thank you 🙏 my calorifire has two coils I didn’t go into this as I wanted to keep it simple as possible for people to follow along 👍
Been running this method in myself build camper for last ten years, been working perfectly with a shower and sink set up. Next build with have excatly the same. Great video
Similar setup to my kit Mel, I have a big tank out of a yacht! Some things I planned to do, one was to ensure the tank of cold water doesn't act as a 'cooler' to a cold engine. Think of it, to get hot air in the cab you will have to get the tank up to temperature as well meaning you may not get hot air to demist your screen for quite a while? My solution is a inline thermostat, Ridex make one for £12, as soon as the water in the engine is at 80 degrees it opens to the tank, just make sure the engine thermostat is hotter then the inline thermostat and you will get hotter water for your tank before the vans radiator gets the hot water. Hope that makes sense! I advise against fitting this under your van as others have suggested, keep it in the heated van is my advice. No jokes from me today! 😮 😅 👍🇬🇧
if you run the engine heater for 20 mins the water in the calorifier will be at engine running temp sowhenyou start your engine it wont take long for it to reach opperating temp
Dont you love it when a plan comes together. Could you also use those underslung pipes carrying hot water to keep drinking water/grey water tanks from freezing?
The water in the pipes will be around 90°C when everything's balanced out which is probably ok for the waste tank (maybe smelly?) but probably not for the fresh water.
Well that was definitely worth waiting for 😂😂 you had us in stitches! 😂😂 Loved the Irish " sketch", although not sure about Jess goingbinto a Yorkshire accent half way through 🤣🤣. I'm going to start calling Carol "The Admiral" (shes done some sailing) in line with you Caling Jess "The General", as while we were watching a message came through on my phone so Ilooked down at it to be told ' put that f ing phone down we watching this'! 😂. Then She had to let the dog out and says ' you can pause hat I want to see this' 😂. Anyway great video as usual, and Ive just noticed the reg on your landy TBT.....'" Tool Box Tuesday" !😁👍Great joke by the way🤣🤣. Take care Guys. Colin, Carol (The Admiral) &"Joy". 👩🦲👩🦳🐕🚐🙂👍
G'day Mel, as always great and informative vid but may i suggest turning your calorifier tank so your inlet/outlet pipes and electrics are facing the rear of the van. If your driving on wet roads you will have water being forced onto the electricals, even though you have sealed them, or if driving on unsealed roads you will encounter rocks and stones being kicked up by the front tyres an possibly braking the plastic push in fittings
@@BigVanSmallWorld You may be able to find a decent plastic water tank you can cut the top off to make it the perfect height, insulate the inside, drill out the bottom four corners to line up with those drop bolts/threaded bar and offer it up and bolt it on. Leave the bolts on that are already there but use some pipe for 1 1/2" spacers to allow for 1 1/2" insulation, drill a couple of holes in the bottom for drainage just in case. When offering the plastic/ABS tank up, use large washers with the nuts, or 2" x 2" steel plate with with the appropriate size hole for the threaded bar. Easy, protective and extra insulation plus it would be lightweight Mel. 👍🐕🚐👊
Hi Mel great video thanks ! Could you change the feed to the pre heater ( copper pipe ) to run behind exhaust against bulkhead, creating a drip loop and be neater and safer ? love the lower under vehicle install of the calorifier
Hi there Mel, What a Brilliant Video. Much appreciated too for your shared time with us. If ever I got to wanting one of these Calorifier’s this video for sure will play it’s part in fitting one into my own Vario. Thank You very much. One little niggle in line of respect for your good self, Consider fully encasing your own calorifier for the protection of any unwanted elements and possibly 25’mm insulate the whole inner casing for the longevity of your calorifier Good Luck my friend Steve from Manchester.
@BigVanSmallWorld hey Mel, great info on lots of options, always appreciated. Could you show a little how to video on using the copper brake tubing instead of nylon? I imagine you have to flare the ends and use some kind of transition material from the appliance barbs? Thanks!
Hi Mel I'm totally invested in watching your build you've got me hooked Very interesting to see how the calorifier and pre heat works and looks like the perfect set up Eager to see your proposed van layout .... a worktop scribble of your floor plan will be suffient lol I think we're all dying to know! All the best with your new project 👍
5:50 the hot water circulating around your engine is controlled by a thermostat which usually opens at 88°C so that your "up to 85°C" _will actually_ be *_over 85°C_* when everything has warmed up & because it's a pressurized system *_can reach 120°C_* when the engine is getting towards overheating! You will have to think *_seriously_* about what you're going to do about the steam generated in your calorifier when the engine temperature goes up! (Limescale will also be precipitated from boiling the water).
Another excellent video Mel! Alas, you are teasing me with your Vario build....my dream van that will remain a dream. The calorifier system is a superb idea and something I will recommend to folk starting out on their build however, I have spent a lot of time and money on my lpg system so it'll be staying put. The engine preheater will be something that I will now consider seriously, if only to help reduce engine wear during cold starting. Good to see lots of mechanical stuff Mel 👍
I hung my lpg tank under my van in this way with unistrut. I used a car jack to lift the tank though. It's been hung for a few years with no problems. I'm not sure if they still do "red diesel". I think I heard they were claiming duty back in some other way now?
Bad idea, you need a splash guard as a minimum as you have it facing towards the front of the van. The two thermostats on the housing never have a long life span, sealing them in will just give you a headache not very far down the line. Box it in for a better and longer lasting job, and the pipes need better lagging.
10:47 can i recommend that rather than modify your calorifier you put it in an insulated box? This will still keep the salt spray etc off your electrics etc but will also have the bonus of keeping it warmer for longer (depending how much hot water you draw off).
And the feed and flow pipes will reduce the efficiency by pre chilling the feed water and cooling the outflow to wherever. Then there’s rocks thrown up at the tank and pipes? Too much of a risk especially with the massive extra space in the new van.
Excellent video Mel. Very informative and well presented. I know the square root of f* all about building camper vans, but I didn’t think putting the calorifier under the van was a good idea (road dirt, corrosion, etc.). Did you think it would take up too much space inside the van?
That was great fun, and I didn't get my hands dirty even once. Its a super idea and a van that big can easily accommodate it. Will you be insulating the tank as well to save heat through the colder months? 👋
Hi. Great video Mel, very informative! Im a beginner about to embark on a self build camper conversion so am trying to soak up all of the info I can & your video helped a great deal 👍 Can you tell me why you went for a dual voltage calorifier, rather than just a 240v only please? (I am trying to learn so sorry if it's a dumb question). I plan on being off-grid 95% of the time & would like to use a 22 litre Surecal calorifier. I would like to heat my water in the van via 3 options: the vehicles engine, via a diesel heater & very occasionally via hook up. I plan on using the Bobil Vans Hybrid Kit too (heat exchanger, diverter, Smart controller etc), so what voltage calorifier would you recommend that I would need Mel? Any help you can give me would be greatly appreciated!Looking forward to the next video, I am learning a lot from you, thanks Mel, good job!l regards Tracey 😊
Mel that was AMAZING!! Such a thoroughly indulgent hour or so learning so much - thank you 😎 I’m keen to fit an engine pre-heater to my Citroen Relay - is it possible to control one using an afterburner?
3:07 how is your cab heater controlled? Some cab heaters leave the water circulating & control mixing of hot & cold air but some just have one air passage & control the water flow, shutting the water circulation off completely to provide cool air. If the water through your cab heater is valved none of your extra kit will see any circulation if you just tap into one heater pipe, to get flow with a valved heater you have to tee into both heater pipes.
Hi Mel. With the extra amount of height you have under your van, would it not be an idea to box in the Calorifier and have an access door. That way it would be protected from the weather.
How do you heat up the water with the heater and not heat up the engine. Ive seen heat exchanges used but then you need a separate expansion tank or do you? Are you planning on having a full hydronic system?
Sounds obvious but cound you not find a flat seal instead off tiger seal? Also would cut down the rods as it’s more threads when rusty to wind down Incase of removal.
Hi Mel. Great video. If I was to replicate the same ways of heating hot water as yourself using a calorifier, ie via engine, hookup/inverter 240v, 12v solar & via bobil vans diesel heater system, how would I rig up the bobil vans system to the calorifier? I understand from your video how to rig up the engine coolant to the calorfier, but not sure how I would have the bobil vans hot air water system rigged to the calorifier? Can you explain this to me please Mel? Thanks Tracey 😊
Hi Tracey if you go to there website and look at downloads you will find this hopefully this helps www.bobilvans.co.uk/_files/ugd/67186c_3e9197485d204d64b8b3460825677efa.pdf
Hey Mel i've clicked your links for the surecal Calorifier but they don't look the same as yours, it looks like yours has a twin coil, there's the two in and out pipes you point to then there's 2 pipes above those then there's the cold in and hot out, love the idea
The one in my video looks different to the ones on there website but they do sell the same ones if you call Bobil vans and tell them you want the same as mine In sure they can help you there phone number is on there website
@@BigVanSmallWorld I did email them they said they sent you a single coil one, I took a pic of you demonstrating your one and sent them it they’ve not responded yet but I’ll call them Tuesday cheers Mel
I wanna add one of these in-line with my Truma D4E. I am wondering if the Truma will trip if it sees the 'cold' water inlet is around 55degrees. I suppose I could add it after the Truma but then I am wondering if I will need to drain 10 litres of water before it gets hot (say I ran the Truma first and the calorifier was cold, then ran my shower).

I have a 50 litre example. in my house, fitted it into a cupboard then packed it with a quilt. You will find it will not keep the water temp for that long especially open to the wind. However they are the only cheap option for hot water but as good a target as a catalytic converter to scum bags...
You don’t need to glue the electrics cover down just use ignition sealer spray on the electrics, job done!
Excellent video. I like the introduction of the engine pre heater. might get one of these. the link for the heater shows a different one, I was just wondering what the extra two pipe fittings are (10 and 2 o'clock orientation, I had a 15 litre calorifier in my last van, it was enough to shower two people easy. you will have plenty of free hot water, I also found out that using the engine cooling system while driving to heat the water is much faster than 12 volts and 240 volts elements. Thank you
Hi Zack that’s great to know thank you 🙏 my calorifire has two coils I didn’t go into this as I wanted to keep it simple as possible for people to follow along 👍
Been running this method in myself build camper for last ten years, been working perfectly with a shower and sink set up. Next build with have excatly the same. Great video
Good stuff!🤓👍
Very interesting Mel love it
Similar setup to my kit Mel, I have a big tank out of a yacht!
Some things I planned to do, one was to ensure the tank of cold water doesn't act as a 'cooler' to a cold engine. Think of it, to get hot air in the cab you will have to get the tank up to temperature as well meaning you may not get hot air to demist your screen for quite a while? My solution is a inline thermostat, Ridex make one for £12, as soon as the water in the engine is at 80 degrees it opens to the tank, just make sure the engine thermostat is hotter then the inline thermostat and you will get hotter water for your tank before the vans radiator gets the hot water. Hope that makes sense!
I advise against fitting this under your van as others have suggested, keep it in the heated van is my advice.
No jokes from me today!
😮
😅
👍🇬🇧
if you run the engine heater for 20 mins the water in the calorifier will be at engine running temp sowhenyou start your engine it wont take long for it to reach opperating temp
Well done Mel 👍 another job ticked of thr list
Thanks 👍
I recon you should swap the nut under the Uni-Strut for locking nuts or use some thread lock. Wandering nuts could get you in bother...
Great vlog Mel 👍
Great job 👏 👍
Be safe
Thank you! You too!
Dont you love it when a plan comes together. Could you also use those underslung pipes carrying hot water to keep drinking water/grey water tanks from freezing?
The water in the pipes will be around 90°C when everything's balanced out which is probably ok for the waste tank (maybe smelly?) but probably not for the fresh water.
Well that was definitely worth waiting for 😂😂 you had us in stitches! 😂😂 Loved the Irish " sketch", although not sure about Jess goingbinto a Yorkshire accent half way through 🤣🤣. I'm going to start calling Carol "The Admiral" (shes done some sailing) in line with you Caling Jess "The General", as while we were watching a message came through on my phone so Ilooked down at it to be told ' put that f ing phone down we watching this'! 😂. Then She had to let the dog out and says ' you can pause hat I want to see this' 😂. Anyway great video as usual, and Ive just noticed the reg on your landy TBT.....'" Tool Box Tuesday" !😁👍Great joke by the way🤣🤣. Take care Guys. Colin, Carol (The Admiral) &"Joy". 👩🦲👩🦳🐕🚐🙂👍
Thank you Mel, that was super informative, really enjoyed.
Glad it was helpful! For the positive feedback really appreciated it 👍🤓👍
G'day Mel, as always great and informative vid but may i suggest turning your calorifier tank so your inlet/outlet pipes and electrics are facing the rear of the van. If your driving on wet roads you will have water being forced onto the electricals, even though you have sealed them, or if driving on unsealed roads you will encounter rocks and stones being kicked up by the front tyres an possibly braking the plastic push in fittings
G Day buddy thank for your concern I should have mentioned in the video I’m going to box it in once it’s all up and running 👍🤓👍
@@BigVanSmallWorld You may be able to find a decent plastic water tank you can cut the top off to make it the perfect height, insulate the inside, drill out the bottom four corners to line up with those drop bolts/threaded bar and offer it up and bolt it on.
Leave the bolts on that are already there but use some pipe for 1 1/2" spacers to allow for 1 1/2" insulation, drill a couple of holes in the bottom for drainage just in case.
When offering the plastic/ABS tank up, use large washers with the nuts, or 2" x 2" steel plate with with the appropriate size hole for the threaded bar.
Easy, protective and extra insulation plus it would be lightweight Mel.
👍🐕🚐👊
Hi Mel great video thanks ! Could you change the feed to the pre heater ( copper pipe ) to run behind exhaust against bulkhead, creating a drip loop and be neater and safer ? love the lower under vehicle install of the calorifier
Great idea!
You could use butyl tape as sealant. It is easy to take off anytime and reseal with it again. It is used in boats. Good luck.
Great idea
Hi there Mel, What a Brilliant Video. Much appreciated too for your shared time with us.
If ever I got to wanting one of these Calorifier’s this video for sure will play it’s part in fitting one into my own Vario. Thank You very much. One little niggle in line of respect for your good self, Consider fully encasing your own calorifier for the protection of any unwanted elements and possibly 25’mm insulate the whole inner casing for the longevity of your calorifier
Good Luck my friend Steve from Manchester.
Hi Steve yes I’m going to box it in 👍🤓👍
Loving alllll this build so much ❤ thanks for sharing Mel 😊
One small question will it be ok out in the elements.. getting wet/muddy underneath?
Thank you!! 😊
@BigVanSmallWorld hey Mel, great info on lots of options, always appreciated. Could you show a little how to video on using the copper brake tubing instead of nylon? I imagine you have to flare the ends and use some kind of transition material from the appliance barbs?
Thanks!
Great antifreeze your using there mel aswel as the oil is the best on the market, i use to work for the company 👍👍
Oh really that’s interesting thank you 👍🤓👍
@@BigVanSmallWorld also all the oils produced are made solely from virgin oils non are a product of reblended/recycled oils ....👍👍
exhaust looks like its pointing up a bit apart from that i like lol
If looks could kill when the fella started whistling 😳. Nasty mel raised his head 😂😂
Haha
Hi Mel
I'm totally invested in watching your build you've got me hooked
Very interesting to see how the calorifier and pre heat works and looks like the perfect set up
Eager to see your proposed van layout .... a worktop scribble of your floor plan will be suffient lol I think we're all dying to know!
All the best with your new project 👍
Thank you 🙏
15:49 I suspect you'll want to set that around 35°C to 40°C once you get used to it but time will tell...
5:50 the hot water circulating around your engine is controlled by a thermostat which usually opens at 88°C so that your "up to 85°C" _will actually_ be *_over 85°C_* when everything has warmed up & because it's a pressurized system *_can reach 120°C_* when the engine is getting towards overheating!
You will have to think *_seriously_* about what you're going to do about the steam generated in your calorifier when the engine temperature goes up!
(Limescale will also be precipitated from boiling the water).
Bin wagons have had these for decades for the lads to have a wash.
Another excellent video Mel! Alas, you are teasing me with your Vario build....my dream van that will remain a dream. The calorifier system is a superb idea and something I will recommend to folk starting out on their build however, I have spent a lot of time and money on my lpg system so it'll be staying put. The engine preheater will be something that I will now consider seriously, if only to help reduce engine wear during cold starting. Good to see lots of mechanical stuff Mel 👍
Thank you 🙏
I have the 22 ltr in my current lorry and I’m fitting the same in my new lorry it’s an awesome set up
Great options there , love my bobil. Why didn't you use a thermo top?
I hung my lpg tank under my van in this way with unistrut. I used a car jack to lift the tank though. It's been hung for a few years with no problems. I'm not sure if they still do "red diesel". I think I heard they were claiming duty back in some other way now?
My local garage is still selling red and LPG
Thanks
Thank you so very much that’s really kind of you 🤓🍻👍
Hats off to you Mel ❤ great job
Thank you ☺️
Thanks for explaining this and expanding my knowledge
My pleasure!
Great video buddy😊
Learning loads from you 😊
Great thing to have fitted to your camper ❤
Glad you enjoyed it😁👍
Bad idea, you need a splash guard as a minimum as you have it facing towards the front of the van. The two thermostats on the housing never have a long life span, sealing them in will just give you a headache not very far down the line. Box it in for a better and longer lasting job, and the pipes need better lagging.
It’s not finished yet 🤓👍
10:47 can i recommend that rather than modify your calorifier you put it in an insulated box? This will still keep the salt spray etc off your electrics etc but will also have the bonus of keeping it warmer for longer (depending how much hot water you draw off).
Great idea 💡 👍
that van is gonna be a total machine !! can’t wait to see it finished and on some adventures,have you got a finish date in mind ?
Thank you I’m not rushing it lol 👍🤓👍
Why won’t the cold water side of this not freeze up in the winter 🥶? Serious question 😊
And the feed and flow pipes will reduce the efficiency by pre chilling the feed water and cooling the outflow to wherever. Then there’s rocks thrown up at the tank and pipes? Too much of a risk especially with the massive extra space in the new van.
You will see in future videos the reasons why we’re doing everything this way
Excellent video Mel. Very informative and well presented. I know the square root of f* all about building camper vans, but I didn’t think putting the calorifier under the van was a good idea (road dirt, corrosion, etc.). Did you think it would take up too much space inside the van?
Glad it was helpful!
Great content loved it
Thank you that’s very kind of you to say 👍🤓👍
That was great fun, and I didn't get my hands dirty even once. Its a super idea and a van that big can easily accommodate it. Will you be insulating the tank as well to save heat through the colder months? 👋
Glad you enjoyed it!
Very cool.
Thank you 🙏
Hi. Great video Mel, very informative! Im a beginner about to embark on a self build camper conversion so am trying to soak up all of the info I can & your video helped a great deal 👍 Can you tell me why you went for a dual voltage calorifier, rather than just a 240v only please? (I am trying to learn so sorry if it's a dumb question).
I plan on being off-grid 95% of the time & would like to use a 22 litre Surecal calorifier. I would like to heat my water in the van via 3 options: the vehicles engine, via a diesel heater & very occasionally via hook up. I plan on using the Bobil Vans Hybrid Kit too (heat exchanger, diverter, Smart controller etc), so what voltage calorifier would you recommend that I would need Mel? Any help you can give me would be greatly appreciated!Looking forward to the next video, I am learning a lot from you, thanks Mel, good job!l regards Tracey 😊
Hi thank you for your support really appreciated I think your best talking to Bobil they are really friendly and they know stuff 👍🤓👍
Wicked vlog mate!
Great video I’m now thinking could I get one to work with a recirculating shower
Potentially
Mel that was AMAZING!! Such a thoroughly indulgent hour or so learning so much - thank you 😎
I’m keen to fit an engine pre-heater to my Citroen Relay - is it possible to control one using an afterburner?
3:07 how is your cab heater controlled?
Some cab heaters leave the water circulating & control mixing of hot & cold air but some just have one air passage & control the water flow, shutting the water circulation off completely to provide cool air.
If the water through your cab heater is valved none of your extra kit will see any circulation if you just tap into one heater pipe, to get flow with a valved heater you have to tee into both heater pipes.
Interesting 🤔 ill have to check that thanks 🙏
Well Mel, one of the best videos I've seen. Very informative indeed, looking forward to this build for sure. Well done.
Much appreciated!👍🤓👍
A interesting product🤙essentially a mini indirect emersion heater?
Brilliant video Mel - incredibly educational! Keep them coming!
Thank you! Will do!
Hi Mel. With the extra amount of height you have under your van, would it not be an idea to box in the Calorifier and have an access door. That way it would be protected from the weather.
Great idea!
How do you heat up the water with the heater and not heat up the engine. Ive seen heat exchanges used but then you need a separate expansion tank or do you? Are you planning on having a full hydronic system?
Calorifier Calorifier Calorifier 😂 I usually watch right through but not today Mel my head was burst.
Sorry to hear that
Sounds obvious but cound you not find a flat seal instead off tiger seal? Also would cut down the rods as it’s more threads when rusty to wind down Incase of removal.
I have 👍
"Treasure Hunting" ? What and where are you planning on heading Mel, panning for gold?
Yes 👍
Wow you are one clever man.
Thank you ☺️
Great video as you dint do any cooking mel lol
I didn’t get time to cook anything 😑👍
Hi Mel. Great video. If I was to replicate the same ways of heating hot water as yourself using a calorifier, ie via engine, hookup/inverter 240v, 12v solar & via bobil vans diesel heater system, how would I rig up the bobil vans system to the calorifier? I understand from your video how to rig up the engine coolant to the calorfier, but not sure how I would have the bobil vans hot air water system rigged to the calorifier? Can you explain this to me please Mel? Thanks Tracey 😊
Hi Tracey if you go to there website and look at downloads you will find this hopefully this helps www.bobilvans.co.uk/_files/ugd/67186c_3e9197485d204d64b8b3460825677efa.pdf
Another top video Mel.. very entertaining and extremely informative 👍
Glad you enjoyed it
Does the fittings system youve built allow for any expansion or contraction of the vessel when clamped tight!
Yes it’s perfectly fine as I’ll be using an expansion tank on the hot water side
Hey Mel i've clicked your links for the surecal Calorifier but they don't look the same as yours, it looks like yours has a twin coil, there's the two in and out pipes you point to then there's 2 pipes above those then there's the cold in and hot out, love the idea
The one in my video looks different to the ones on there website but they do sell the same ones if you call Bobil vans and tell them you want the same as mine In sure they can help you there phone number is on there website
@@BigVanSmallWorld I did email them they said they sent you a single coil one, I took a pic of you demonstrating your one and sent them it they’ve not responded yet but I’ll call them Tuesday cheers Mel

I wanna add one of these in-line with my Truma D4E. I am wondering if the Truma will trip if it sees the 'cold' water inlet is around 55degrees.
I suppose I could add it after the Truma but then I am wondering if I will need to drain 10 litres of water before it gets hot (say I ran the Truma first and the calorifier was cold, then ran my shower).
I’m sorry I don’t have a trauma so I have no experience with them
