Love nerding up on Gregs videos! Thank you Greg for your time and reliable info!

[@reohtz4878]

This was the best explanation of the Truma Combi system that I have seen. Even a tour of the Truma factory in Munich Germany, with commentary by Truma engineers, produced by the Fit RV, another RV channel on KZbin, did not cover it as well as you did. Kudos to you for a great and informative video. Cheers from Houston Texas!

[@GregVirgoe]

wow, I don't know what to say. Thank you for such a fantastic comment.

[@kevgermany]

As an IT guy, I learnt to turn ideas into reality by research, design, think, review, think, review, think, review and only then build. Yours is the only van build series that has clearly done that. The design/build it as you go approach may be valid, but leads to most people having a big list of things they wish they'd done differently. And the van becomes an ongoing reconstruction project.

[@GregVirgoe]

kevgermany I had a pretty solid plan from the start to know where I needed to run services during first fix. My years of project management obviously paid dividends there. Thanks for the appreciation

[@lastfrontier_vanscapes5694]

Greg your attention to detail is absolutely remarkable, your planning is unrivaled. Many thnaks like always for your videos they are phenomenal.

That's really nice of you to say so thank you very much

[@scottnewell5455]

I am a mechanical services electrician, although we do things more so related to cooling rather than heating in Australia, fantastic video series you are producing a big thumbs up

[@ThePigbreeder]

I was surprised to see that this kind of heater exists factory made. I have planned to make a same type of heater system with a diesel Eberspächer/webasto, a radiator, a watertank and piping with reservoir and "coolant". Great video, as all the ones before. Really helped with planning my build!

[@GregVirgoe]

I was searching for some time for the perfect showering and heating solution. This boiler does have a lot going for it. Pleased it was useful to you.

[@barrycook4690]

Can't wait to see you install the heater and get running,all the best

[@GregVirgoe]

Many thanks for your continued support Barry

[@andersandersson9442]

Very nice presentation. I have been using my Truma in our RV since 2008 and still working as good as new. Good quality and great performance. Don’t have the option of electric heating of the water but yet but that is a spare part that I hope to install now that I am extending my roof solar from 100 watts to 1000 watts and a 3000 watt inverter.

[@GregVirgoe]

That’s great to know you’ve had 9 years good service. I’m only planning to use the electric heating when on hook up as 900w or 1.8kW would kill my batteries in no time.

[@morganplatt6762]

Just found your channel Greg. I'm glad I did. Excellent presentation. and clear drawings. Great stuff, just subbed.

Than you very much for such great feedback and i'm pleased you enjoy the videos

[@Joop3000]

Greg, Thank you very much for putting all this very usefull info out. As a fellow engineer, I really like that you have thought trough everything yourself instead of copying from one video to the next. I see people doing things that makes me rethink all their information, but I also don't want to reinvent everything. I don't worry about that with your videos. I'm going to build next 6 months and then travel around Europe for atleast a year. Your videos are very helpfull. Thanks!

[@GregVirgoe]

Yes I too have seen lots of silly mistakes and mis information. I do my best to give the right information that also com plus with any codes and standards so I’m happy that you are getting sound advice. Thanks for the great feedback and best wishes with your build 😃

You sir, know your requirement and the correct solution very well! I enjoyed your explanation of the heating system & its functions. Seems like high tech equipment. The ability to have a place to dry clothes is a advantageous. Eagerly waiting for the installation video.

[@GregVirgoe]

Thank you, I think the vent in the wet room will be a game changer, we could also dry some washing in there too.

[@Squiibbin]

That's some nice kit Greg. I'll have to save up and bookmark these next few install vids for later!

[@GregVirgoe]

Yes, this is a game changer for us for sure.

Excellent video Greg. Up to your usual very high standard. Perfectly explained. Regards Mark in the UK.

[@GregVirgoe]

Many thanks, Mark, I had two bites at this one, the first days shooting it took me an hour to get 30seconds of usable film. Still, there's plenty in the can for the gag reel lol

[@iainroebuck6742]

Great Video Greg. The mystery of the boiler is solved. Always wondered what made a Truma so efficient and user-friendly.

[@GregVirgoe]

Warm air heating has been about since Roman times, and the boiler since the industrial revolution, but now we can control it to fractions of a degree and from anywhere we like. Definitely a very nice bit of equipment.

[@iainroebuck6742]

Yes most defiantly. The ingenuity of the Romans never ceases to amaze me.

[@martinmallory3626]

With the effort you put into the vlogs can’t wait to see the van finished, good luck with the build .

[@GregVirgoe]

It's taking a bit longer than anticipated but the effort will be rewarded. Many thanks for your support

[@leestewart4064]

Another excellent video Greg , I have been pondering what system to put in my sprinter as we are at the same stage of the build in our sprinter. You have most definitely sold me on the trauma system also my wife as she’s always cold and it’s a big concern for her , Thanks for another great video and eagerly awaiting the next instalment

[@GregVirgoe]

This heater certainly will deliver bags of heat, we will definitely not be cold in our van that's for sure.

[@Navillus2273]

Nice one Greg... I hope your keeping all the plans and blueprints as you go, because I would want you to mass produce these motor-homes and I will want to be your first customer!!!!!!!

[@GregVirgoe]

Hello, I have got all the details. Looking into producing a self build guide. I can now appreciate why motorhomes cost so much. The labour alone is a lot of hours. I’m gonna need a holiday after this project. 😂

[@mrmackey1119]

[@daxw2460]

You should make a how to build your camper. pop up book Greg!

[@bokaab]

Awesome video! Thank you. looking forward to the follow up installation videos as well .

[@GregVirgoe]

Have been running all the power and control cables for this system today. :D

[@MrDehicka]

Thanks for the great video! I'd still go for diesel version if you plan for more than couple of days offgrid in cold weather. Combi 4 eats around 0.2Kg (0.4L) LPG per hour in a van like your Sprinter with 0-20 temperature gradient. This is roughly 10L LPG tank per day even without cooking and hot water. And Webasto dual top can be mounted outside and free additional 70L of living space.

[@GregVirgoe]

I will give you some exact usage data once we are on the road. Its all relative to how well the van is insulated as to how long the heater is running. Plus if we are cooking the heating will not be required either. We don't plan to spend too much time in the cold as winter camping is not very enjoyable. We will be on the Med by winter where its a bit more temperate.

[@britironjon7635]

Brilliant Greg been looking for a video on these Heaters as I planing to fit one seen plenty of good reviews on them but not any good videos looking forward to seeing your up coming videos . thanks

Thank you, what vehicle are you working on?

[@britironjon7635]

Hi greg it's a peugeot boxer lwb still a long way to go yet iv put few clips on my channel cheers

[@lass-inangeles7564]

Thank you for explaining how this works, excellent diagram and detail! Its a very efficient system. Outside and inside air are heated, and while air heater is on, it also heats up the water, very smart! The phone app and SIMM card remote control, propane tank accurate gauge is just genius! Truly remarkable German technology! Even named after US President Truman! When I build my van, I don't care how much this costs or how hard to get hold of one, I am getting this system and no other. Its a marvel of science and so beautifully created that it should belong in the Museum of Modern Art (MOMA). Here are some other facts for viewers: 1. The only deal breaker for Americans may be that this runs on 240V so do they make a version for US market at 110V or will this run on a step down adapter from 240V to 110V? 2. I looked up cost on ebay and its not cheap at US $2700 approx. 3. Truma in Germany does not sell the Combi directly to consumers, only dealers. 4. You can look up specs and buy it from this Aussie dealer at AU $2400 + AU$32 shipping. www.mygenerator.com.au/truma-combi-4e-kit-gas-heater-hot-water-system.html 5. The weight of the Truma Combi 4e is 15.8 kg or 35 lbs 6. On the link above, you see all accessories, ductwork diagram, and specs. 7. Yes, you can run the water heater independently of the furnace heater. However, your hot water is also heated for free if you run the furnace. 8. Combi runs on a variety of fuels and power sources: gas, diesel, propane, AC, DC, and using hot engine while driving if you duct it that way. Refer to link above. Thank you Greg, for another great video and adding to the RV/Caravan knowledgebase!

[@tomrankin2564]

Simply amazing! Such a great help these videos are 👍🏻👍🏻👍🏻👍🏻

[@ARepublicIfYouCanKeepIt]

Another wonderful video from a master content creator! Love the Truma Combi units. However, they're way out of my price range. Therefore, it's a 16K BTU direct-vent propane heater, plus direct-vent instant hot water heater (also propane-fueled) for me. As always, I'm looking forward to your next great video Greg. Keep up the brilliant work.

[@GregVirgoe]

Really appreciate your continued support John, Thank you

[@alba9507]

Another great piece of info Greg. I was originally thinking of a heater similar to the night heater in my truck running on diesel, but this system is far superior & combines the hot water function. Once again your info is a great help in my research before I take the plunge.

[@GregVirgoe]

You're most welcome John, I'm pleased it was useful to you.

[@pulsey2001]

I know you can insulate the area this will be contained in but do you know how many db's radiate. Thank you for the video's Greg, I've searched around on KZbin and this is the most informative I've found so far... Just brilliant.

[@GregVirgoe]

Hello Tony, I do not have the data for dB rating. Centrifugal fans are usually very quiet these days. As long as you have adequate airflow and not restricted it should be quiet.

As an update, there are more affordable versions of the Truma around now that run off diesel and/or electric - we bought ours from Bobil Vans and it's fantastic. After-sales is great too.

[@lunaraerialimaging1425]

Hi Greg, As everybody says, your videos are by far the best out there for both the way it is presented and the knowledge passed on. My question is why did you choose the 4E over the 2E or 6E, Thanks Greg

[@GregVirgoe]

At the time the 4E was the smallest option available and given the choice now it would still be better for heating the water quicker. I think 6kw would be far too much

[@ammcknockiter]

LOVE THE VIDEOS. Can you heat the the water without heating the van up if in a hot country or in the summer

[@lass-inangeles7564]

Of course! Its two separate functions in one package. Use one or the other or both.

[@malcolmrowe5031]

I can't believe it's got 2 dislikes! Excellent video, maybe I'll see you touring Europe in the summer, 4 months and 5800 miles planned! On the level sensor, what happens if you have 2 bottles? Gaslow is steel, why not Alugas, lighter, any disadvantages? I'm looking at re-fillable ones to.

[@GregVirgoe]

Hi Malcolm, you never know our paths could cross, sounds like you have a definite route planned. We are going to be much more winging it. For two cylinders you will need a level control device attached to each one, the level of each is displayed separately on the App. The device is magnetic so steel tank is preferable. Although they do a fixing bracket for non magnetic cylinders. www.truma.com/uk/en/products/truma-caravan-rv-gas-fittings/truma-levelcontrol.html

[@malcolmrowe5031]

Greg Virgoe thanks for that I'll look into it, yep you never know, take care 😀

[@matthewhelliwell6485]

Great video again Greg! We were or maybe are going to go for the Truma 4e but I've seen a few videos and a lot of people claiming you only get 1m 50s of hot water in a shower. Thats ok for me, but if the wife is washing her hair that's not long enough. Are the water heaters window cleaners use not a better option in a camper for continuous hot water (providing you can supply it with a decent feed?)

[@GregVirgoe]

The Truma heats up to 60°c so you have to mix that with same amount of cold to bring it down to shower temp. Best to use a head like ours with a trigger so not wasting water when lathering 🧼 then you have plenty to rinse. Obviously it’s not like at home but it’s definitely sufficient for us.

[@matthewhelliwell6485]

Thanks for confirming Greg! Look forward to more of your videos. All the best

[@loicvourey]

Hi Greg. Great video and great use of Sketchup too. Didn't you say in your video that you were to shoot a video of the Truma being installed? Have you done it yet? Can't find it and definitely need it as I am planning installing mine in the coming weeks or so! :)

Greg - thanks so much for these brilliant videos - really clear and informative. I'd love to know whether this combi would be practical to work on electric input, as i'm trying to avoid an extra gas tank. Would it be practical/efficient?

It would be fine on electric hook up but would draw too much power from a battery system. 👍🏼😃

[@sallywilliams6272]

@@GregVirgoe thanks v much for speedy reply! - good to know. Guess that would be the same for a Truma Therme too then…

[@GregVirgoe]

@@sallywilliams6272 the Truma has two 900W electric heaters inside where the Therme has just one 300W element. So to heat the same quantity of water the Therme would take 6x longer. In the end they would have used the same amount of electric.

[@fionalambert7274]

Hello Greg. Love the build series by the way. Glad that you got home safely. I have a Truma trumatic C Combi boiler in my sprinter conversion, the one with the grey circular dials. Can these dials be changed to more upto date digital controls like you have on your Combi 4E. Just thought I would ask as you might know what I'm asking. Thank you

[@GregVirgoe]

Hi Fiona Lambert, thanks for watching the channel. Hope you are well. Sadly the old style controls are mechanical and not digital. So they act like simple switches. The technology in the heater would not be there to plug in something more advanced. Sorry that’s not the news you wanted. Take care 😊

[@gavinconlon9240]

Hi Greg. Great videos . Just wondering why you chose the 4e and not the cheaper 2e? .

[@GregVirgoe]

It will heat the water to full temp in less than half an hour from cold. :D

[@gavinconlon9240]

According to the Truma info sheet the 2E does the same water heating time . I guess it will heat the cabin slower perhaps .

[@raytandy8142]

Great video can you tell if I can use the heater when the boiler is empty after I’ve drained the water for winter thanks Ray

[@BsYtHandle]

Hi Geoff, really appreciate your videos. They're so helpful. In your energy use audit video you say that you will not use the boiler unless you are on a hook up, due to the energy consumption. Does that make the boiler less important to your build or has your experience since being on the road make you just as glad that you included it?

[@GregVirgoe]

Geoff?? The boiler is dual fuel so when off grid it runs on LPG. We only use the electric elements when on hook up because they consume more power.

Hey Greg. Love the vid, thanks so much- truly helpful. One Q. For the Combi e models, Can they heat air, and/ or heat water on a 12v supply?

[@stilettosqueak]

Another excellent video Greg. One question though. It was not obvious whether or not you can get hot water WITHOUT having the van heater on. Is this possible with this unit or does it only heat water when the air heater is operational?

[@GregVirgoe]

Yes you can just use it to heat the hot water and not have the heating on in the van.

[@clarktferrill]

Greg Virgoe how much does this unit cost.?

[@FrodoSuper]

Awesome stuff! What size 12v 2 core does this require? And does it come with the boiler or will I need to order extra? Thanks... keep up the good work 🤙🏻

Mine came with the mains cable attached but not the 12v. It requires a 10amp supply so depending on distance you may need 2.5 - 4mm cable.

[@terryc47]

Greg, loved watchding your series on panel van conversion to an RV. I see you take great pride in your work. But I also absolutely love your detailed explanation of every thing you have built, installed or fitted, from how it works, how to install it, the handy hints on how to make it easier through to use of template's etc. While I don't know anything about the Truman, and have never used one, why you picked one makes absolute sense. But I have a question. Now the reason I raise this with you is I'm living in Australia, and it gets very hot here. Does this particular model of the Truman, have a way of venting the warm air outside the van during the summer months, when you only want to heat the water? Interested in your thoughts. I plan on doing a van conversion, soon myself downunder, and your videos certainly are at the top of my list of how to videos, when I get started. Wish you all the very best with your travels around Europe.

[@Rob95Howard]

5 Years on, would you still use this combi system, Gregg? How has it fared over the years?

[@dianavideomarketing]

Hi Greg, great video thanks. Quick question - how does the the Truma wire into the 12v electrics? Can it go straight into a blade fuse in the box or does it need to go via a breaker? Also on the 240v side? Many thanks

[@shorteth]

Hi Greg. Thanks for the wonderful videos. I have a thought. How do you think it would be to use one of the four outlets to blow hot air into several 30mm pipes in the floor as underfloor heating? For example, with XPS made for waterborne heat where the air comes out on the other side of the floor.

[@maximedefooz1268]

Hey Greg ! Thanks again for a superb video Could you explain why you went for a "e" model (230V/110V powering possibility) ? Just when being on-shore power, is it that more economical in the long run ? (being about 450€ more expensive, when bought, here in France) AND I guess we couldn't imagine it being powered by our van's battery ? (obvious I guess..)

Don't expect the same sort of video from me once the system is up and running LOL I've chatted to the misses and shes not game. LPG is a cleaner and greener fuel. I was already installing a GASLOW refillable LPG tank for cooking so it was an easy option.

Greg, I've been binge watching your sprinter build videos. Love them! Do you have any advice for me in the US to purchase the equipment you use such as the water boiler. Or is there a way of getting the equipment shipped, if the company doesn't ship to the US. Thanks for your help! About to start building a ram promaster to be a mobile grooming unit and want to use your videos for the build. Again, love the videos and your attention to detail! :)

[@GregVirgoe]

Toni Sherwood, I would contact the sales office in The UK and ask them direct, I'm sure they could put you in touch with a dealer in USA, if you get stuck please come back to me as I may be able to get advice from the top man 😃

[@lass-inangeles7564]

Toni, remember the Truma runs on 240V and we have 110V in the US. I would first contact Truma in Germany to ask about this problem. You could also contact Winnebago that uses them in their RVs to ask how they resolve this issue. Once this big question is resolved, you can then hunt for a Combi. I contacted Truma but they do not sell the Combi direct to consumers, only the Truma Aquago hot water system. But the Combi is better. So you have to find out why Truma does not sell direct. Is it because it is a 240V and only the RV makers in US can wire it to step down to 240V safely with no liability, or is it because US RV makers want the monopoly and edge of having the Combi while you cannot buy it directly. I will crack it when I am ready. For now, see my comment on top with a link to an Aussie dealer and ask them how to get it for you. But don't forget the 240V issue.

Hi. Looks great. Best wishes.

[@benjames2310]

Awesome bit of kit. Can I ask what your gonna do for a shower cubicle tho.

[@GregVirgoe]

Hello, I have a Thetford C200 cassette toilet with a built-in shower tray. The walls of the cubicle will be covered with Altro Whiterock PVC sheeting.

[@benjames2310]

Thank you .I was looking so hard for a fibreglass moulded shower for a few months now but I'm dead in the water with that one for my budget. But thank you for your help and info on your videos. 👍👍👍

[@sammc4558]

This might sound silly... but can you have the boiler on for hot water without the air heater ? Great video by the way!

[@GregVirgoe]

Yes you can, you would need to do that for showers in summer. We find for a bit of washing up it’s more economical to boil a kettle in summer as it’s less water to warm up. We generally use the hot water in the morning for washing as the heater may have been on in the night to keep the van warm and you get the hot water as a by product of the heating. This really does make it very economical to use.

[@leoinswlondon]

Sir, your videos are absolutely fantastic. I wrote you a message in the previous video, I am wondering if the work shop you ordered your bed would be willing to take another order from me? I am looking to build exactly the same panel bed but finding difficulties to have it welded. Thank you.

[@GregVirgoe]

Than you Leo, I was just waiting for Ged to get back to me. I have replied to your previous message. Thank you

[@edwardcarberry1095]

Blood hell just want I will need! I didn't know anything about this heater. 1,400 OUCH! Will look into it further when

[@johnmanning4577]

Cheers! Love your work....

[@GregVirgoe]

Thank you John

[@lorcro2000]

I'm sure that's a great heater, but I'd still go with an Eberspächer (Espar) Hydronic unit and a small heat exchanger; that gets you hot water without a tank. You can hook up another heat exchange to the glycol and that one will generate hot air instead of hot water. Rixen in the US has a kit, albeit for 120 volts (for the electric heater that can be used instead of diesel when you have shore power.)

[@GregVirgoe]

Hello, to heat water instantaneously via a heat exchanger at a flow rate sufficient to have a shower you would need a big heat source. Most combi boilers that do that in domestic properties are rated at 30kW or 100,000Btu Good luck with your build, let me know how it works out. Cheers

[@scottnormand5858]

How has the truma performed thus far? Think you sold me on it.

[@GregVirgoe]

It is incredible, it just works so well and we use it mostly on eco mode and you can hardly hear it so quiet. You have the benefit of dual fuel when on hook up and the remote control via app on your phone even when away from the vehicle is one of the best features. You won’t regret it 😊

[@scottnormand5858]

This is a huge bummer. Just found out that I cannot get the truma furnace/ water heater for dwisel fuel here in the US. Only motorcoach manufacturers can get it😬

[@roygardiner4002]

Another corker Greg! Have you thought about 'monetising' this series by producing a DVD for aspiring constructors? I'd buy one as a way of thanking you for the excellent content of these videos.

[@antoonensing9093]

Hi Greg, great video. Question though: In one of your earlier videos is see you show a separate system (heater and boiler) i believer it was a Whale boiler and gas propex hs2000 heater. Advantage of this system IMO is that i can install both underfloor, which will save extra space. Another - i would consider as an - advantage would be that it are 2 separate systems, if one is broke, the other still works.... So, my question is, why did you choose for the Truma Combi system? (in comparison to 2 separate systems?). Thanks! Antoon - the Netherlands
