Sprinter Van Hot Water Heater, Hydronic Heating Systems Explained
Looking for a 3 in 1 Van Build diesel water heater for your van conversion? In this Van Build Tech Talk Series episode, Curt goes into detail about a hydronic heating system that sips diesel for power and heats water, air, and warms the under chassis plumbing for cold weather protection. Basically, this is a tutorial on an on-demand heating system that taps into the fuel source of the van. This allows Curt and Snow to take long hot showers with the recirculating shower system installed onboard, heat the van in cooler temperatures, and keep the pipes and tanks from freezing all in one simple system...Mind blown!!!

Dude. Thank you for this video. I've been trying to wrap my head around these concepts, and you spelled it out so well. Much appreciated!

@johanvangelderen289 4 года назад

Good video. Glad to see someone who is actually doing what I'm contemplating in the future. I've looked at some decent quality companies which sell for more reasonable prices than Wabasto and Eberspacher. I've found a Chinese company which sells high end heaters both hydronic and air. One company is VVKB. They have a dealer in the USA. There is also a Russian company which sells both air and hydronic systems. They can be powered by diesel or gasoline. The company has a distributor in the USA. The name is Planar. They are also known as Autotherm. The Russians know all about battling cold conditions. Their stuff is supposed to be as good as the German companies. I've read that diesel units tend to clog with carbon when used at high altitude or on a continuous low setting. It's said that kerosene works a lot better. Supposedly a mix of 80% kero and 20% diesel keeps the fuel pump from wearing out. I've also read that #1 Stove Oil is basically kerosene. Also Jet-A aircraft fuel is highly filtered kerosene. Smaller airports supposedly will sell to folks who don't have airplanes. Both Stove Oil and Jet-A fuel sell for less than consumer grade kerosene. #2 Home Heating oil is basically diesel which has been dyed for tax purposes. It costs less than diesel because the price does not include road tax. I'm just reporting what I've read so far. Do your own follow up.

@SnowAndCurt 4 года назад

Good info... thanks for sharing!

@CosmicSeeker69 3 года назад

legend.... another high grade is the Lavanar Pro range - with a high altitude option.

@Number8of10 2 года назад

Can confirm on the Jet A - used to have Amish come in and buy barrels of the stuff for their lamps. We'd put a adapter on the end of the truck "duckbill" nozzles to fit the barrel openings and be limited to 7gpm which was a fraction of the wide-open flow rate. Was a pain but at smaller airports a customer is a customer. Supposedly it didn't smoke up their lamps like kerosene. Can also ask them if they have any sump fuel they are not using. Regulations require them to pull daily fuel samples and at the airport I worked at we had barrels of the stuff which was still fairly clean. We burned that stuff in the trucks and hangar heaters and still had more than we knew what to do with.

@fisherberry8155 3 года назад

Amazing setup!! Can't wait to see your next vedio. Hydronic system is also something that I am considering for my vanbuild. For my understanding, you are currently using a second coolent loop, separate from the engine coolant loop. Did you consider tapping those together like the hydronic system intended to do at the beginning. This can protect the engine during winter by pre heat the engine also warm up the room!

@SnowAndCurt 3 года назад

Yep... thought about it after the fact and wish we would have... still may do it if we find some down time! CHEERS!

@georgibozhinov8561 3 года назад

Hi Curt, thanks for your engineering experience with installation of the systems in your Van. One day I will build my own Van...one day :) So something pop up in my mind about your freezing problem under the Van. Most probably you did it or at least you have an idea, however 😊 one option is to wraps the pipes with electric wire heaters and control ON/OFF time. It is just idea...a lot more questions pop ups next, but i told you, I am giving just an idea 😊

@SnowAndCurt 3 года назад

Thanks so much for that tip! And thank you for tuning in to our channel!

@jacquesolivier65 4 года назад

Hi Curt, I've already told you but this van rocks ! Everything inside this build is inspiring... I was just wondering if it would have been difficult / reliable / economic to add another heat exchanger in the loop and feed it with your engine coolant. It just needs the pump runnig while you are driving... So as long as you drive, you heat your hydronic fluid and you could just park and shower without using the heater... The main idea is not to waste the engine heat. Because you need to cool down the engine and heat your hydronic fluid, so maybe a simple heat transfer is an idea... Am I wrong ? I can't figure out if it worth the extra piping or not... Regards, Jacques-Olivier

@SnowAndCurt 4 года назад

Jacques, you are spot on. Two reasons I didn’t do that...1)I didn’t have the confidence I could do that myself, which leads into 2) I was concerned a failure in the added system could potentially lead to damage to my engine. I would say if there was no risk the way you described is the way to go. In fact, I may do a bit more research that modification as it would add to overall efficiency.

@karlschmidt7258 2 года назад

Conversely, with the systems tied together, the fluid could be switched to warm up the diesel motor...then possibly only one expansion tank would be needed. It would be imperative to be able to isolate the systems entirely in the event of a leak- easily done with quarter valves. Another consideration is filling the system so no air pockets remain. A vacuum coolant filler can be had for as little as $30. On the other hand, I think I could plan my showers (the only hot water I really need) around my engine run times which would simplify the system but still be the best way for a long shower time.

Thanks for the video. Love the tech talks. Maybe this has been asked, I didn’t read all 190 comments and reply’s. How do you regulate the hot water? Especially in your recirculating shower. If it recirculates wouldn’t it just get hotter and hotter the longer you use it and the more it goes through the heat exchanger? Thanks in advance!

@SnowAndCurt Год назад

We put the shower handle on a little less than medium. It does start to warm up... But it doesn't get too hot for about 20 minutes... So the shower is perfect for a nice long shower.

Propane is a pain like you said a big hassle to get refills or other canisters in the various countries...virtually impossible... plus propane is relatively high maintenance, subject to checks by insurance companies and in some cases authorities and ferry companies. Also propane can be dangerous. You don want to be in a gas explosion if you can help it... And obviously you helped yourself and left out the propane...good man !!!...

@jhvorlicky 3 года назад

Hi Curt. Great videos, so thanks a bunch! Happy 2021! One question - how do you moderate the temperature of the water coming out the shower? I guess you don't use a thermostatic mixer valve because I don't see a separate cold supply... Or do you control the temperature to which the Hydronic heats the water in the loop? Or do you just take what comes out, assuming it never gets too hot because of heat losses in the whole system? Thanks in advance for your advice. Top channel. Yours combined with Greg Virgoe's gets me everything I need so far (at least in the planning stage!)

@SnowAndCurt 3 года назад

We use a mixer valve... Enough heat is lost in the system that it never gets too hot. But, there will be times that all of your water is warm for a bit!

@CTStevens 3 года назад

If a guy wanted a setup like yours & wanted a heated floor & wanted to tie the system into the engine, such a setup would take 4 heat exchangers?

@SnowAndCurt 3 года назад

I think would do it with 3. If I did it all over, I would do as you describe.

@millanferende6723 4 года назад

Thank you for this amazing video! Your series are extremely educational. :) 12:00 - I've always wondered... but then what if you need hot water in the summer? What do you do then? Do you feel if I get a simple LPG gas-boiler, that it would be enough to heat a well-insulated sprinter van?

@SnowAndCurt 4 года назад

Our hot water heat system can be used without hearing the air in the van! Tons of folks use propane to heat their vans... We stayed away from propane only because we are doing extensive international travel.... And the different fittings in different countries can make it difficult to fill your tanks!

@ballancampeau6427 3 года назад

When you route the glycol across the exhaust do you do anything to protect the hose from the heat? Is there a best spot for the crossing? Did you install a heat shield?

@BEAdventurePartners 3 года назад

@leow_se 3 года назад

Hi Curt, I am always up with a long, hot shower so I am doing research into a recirculating shower system with hydronic heating. This is definitely one of the best videos on youtube regarding this topic, thank you sir! Just a few questions regarding this, since the Espar heater is just 5kw, is it enough to instantly heat up the water and keep it warm as you go (maybe a bit colder at the beginning but once the recirculating tank has filled with water it gets warmer?) Do you have any idea of the flow rate of your shower? Does the water get colder when you have a very long shower, to the point where it's too cold to shower with? Keep up the good work, greetings from England.

@SnowAndCurt 3 года назад

Turn the heater on about two minutes before getting in the shower... water is warm within 30 seconds of turning on water after that. The water is easy to maintain the proper temp. Never gets too hot due to a bit of temp loss as the water circulates thru the system... never gets too cold either.

@2gnospam 3 года назад

Thanks for the video! Are there any advantages or disadvantages with tying the engine cooling system into the hydronic heating system?

@mattgosson8697 2 года назад

hydronic guy here - engine coolant (ethylene glycol) is poison. Systems using heat exchangers to heat our domesic water should always use food safe glycol (propylene) in case of failures poison glycol mix with our domestic water.

@babylonfive 3 года назад

Curt, what heat exchanger model did you use? I can't find it on your site... with the squirrel cage blower? I want to find and buy some but can't locate them. Can you help?

@koningbolo4700 3 года назад

The heat exchangers are great technology but what I would like to know is after you switch off the heater, can you still get some hot water from the sink or shower and if so: how much please?? I opted (btw) for a salvaged indirectly heated boiler from a central heating boiler which stores 10 L of coolant and has a copper coil inside which I plumbed via a thermostatic mixer valve into the hot water line of the kitchen sink (my shower is as yet a bucket, a cup and a tarp in the bushes (yeah I like - not really - to rough it sometimes)

@SnowAndCurt 3 года назад

We can get hot water in the sink for maybe 5-ish minutes after the heater is turned off... warm water for maybe 10.

@melaniecollins4045 3 года назад

hey there, been looking for a video on how you weather proofed the under of your van, did you all do one?

@brad450 4 года назад

Maybe this is not the case in the US, but in Canada Sprinters come with a Webasto Parking heater, why not just implement this with the Vehicles pre existing coolant loop and have the benefit of also keeping the engine warm, or use the engine itself (while driving) to heat the coolant?

@SnowAndCurt 4 года назад

Yep.... USA vans don't have that awesome feature! Curt's looked at this a bit and in hindsight would've maybe liked to add this in... But, no going back now! Thanks for the question... It's a good one!

@tblake102 4 года назад

Hi Snow & Curt. Loving your videos, thanks especially for the Hydronic hot water system videos, they are a huge help to me!! Your van is fantastic, well done!! I have a question for you about the electrical power consumption of the hydronic water system, can you give me an idea of the Amps it draws when heating up from cold please? How long does it take to heat the coolant, (I think I remember you stating it takes 5mins but not sure I have that right)? Does the Amperage draw lessen after the initial heat up please & if so, what is the amperage draw then? I'd appreciate any help you can give me. Looking forward to your upcoming videos! Stay safe both of you. Tracey (in the UK).

@SnowAndCurt 4 года назад

Yes... 3 to 5 minutes depending on outside temp! The heater is diesel operated, so the only power draw is the pumps... which is only when the water is running and is minimal! We do not know the exact amps. But, it is SMALL! Hope this helps!

@jeffsteinmetz7188 4 года назад

This was very helpful! Now I understand the second heat exchanger. How long did your entire build take? You have one of the best builds, so I am curious what it will take to get similar results. Any chance you can provide a complete undercarriage plan /layout? Knowing what is in each available space of the undercarriage would be a big help. Thank you!

@SnowAndCurt 4 года назад

Jeff... if we would’ve started with a plan for the undercarriage from the beginning, we could easily share! But since we had to create a lot of the components from trial and error until we got it right, it would be super hard for us to draw up a plan. Lots of folks ask... and we wish we had one, but we do t! Sorry! Thanks for watching!!

@SnowAndCurt 4 года назад

The build took eight months on weekends mostly... with a few full work weeks when curt took vacation from his job! They were long tiring weekends! But, it’s all worth it now!

@gregvittore5004 4 года назад

Well done! 👌 How long does it take to heat the water? I suppose the glycol needs about 10 minutes to heat up.. But as the shower water is at van temperature it will need à couple of minutes to be on the right temp.. But once hot, you can't go down with the temperature, right ? Do you have problems with too hot? Thank you

@SnowAndCurt 4 года назад

It takes about 5 minutes for the heat exchanger to heat up, after that we can control the temperature perfectly for an least an hour and probably a lot more we just have tested it for more. If the water is too hot we just turn it down a bit...Easy peasy!

Can you do a video specifically on your control system? Or at least describe it here? Or is your system right now just set up on a timer? If so, when does it turn on, when does it shut off? The mechanicals and plumbing seem pretty straight forward, but the controller is the thing I feel like I know least about. Someone suggested Inkbird or Pi or Arduino, but this is only half of it, where and how do you mount thermocouples, etc, some in water, some in the air, etc. Lots of questions about the control systems. Anything you can share? Thank you!

We have not done anything special there or made a video on it. Everything is handled with a wall unit and is not triggered by temps. We made add stuff later, but for now we manually flip things on. If you figure something cool out, be sure to keep us posted! Sorry we were not m ore help.

@daemorhedron 4 года назад

Great video, thanks for doing these. Do you just close the loop to the floor during summer so you can still have hot water otherwise? Can you also use the hydronics for cooling floor/air too and thus do away with AC (maybe trade it for a dehumidifier)?

@SnowAndCurt 4 года назад

We actually do not have the heated flooring system... we thought about it, but opted out because we needed every inch we could of space so Curt would be able to stand up in the van. But, we would have for sure made a way to close off the floor loop if we would have. And... your cooling idea is interesting... if you research it more and decide to go for it, be sure to let us know!

@cluek9780 3 года назад

daemorhedron :: Closing that heater loop is optimal in warm weather, especially if it can be repurposed, directed thru a dual-core heat exchanger near an *evaporator tube. My ambulance has (an excess heat production in a 42kBTU Espar M12 from a bus and) such an exchanger, so I’ll be routing hosing for a COOLING WALL (not floor b/c, well, heat rises) as recently demonstrated by a Princeton study (a cooling wall pulls heat from occupants and objects without byproduct condensation). Definitely post your process- and I’ll return the favor.

@112honeybadger3 4 года назад

I have been doing a ton of research for my upcoming build and came across your channel. Great stuff, I really appreciate you sharing your experience with all of the people out here. The question is, how do you regulate the temperature in the radiant system (coolant)? Is there a separate thermostat in the flooring that keeps the temperature of the coolant loop at below 85 degrees F? Most flooring cannot handle radiant systems above 85 degrees and it can harm most wood/laminate flooring if the system runs hooter. How do you keep the PEX and the floor from being like 190 degrees? Having lived in Korea for years, I love floor heat and even sleep on a dol bed (stone bed) with radiant heat. [Google: Korean style dol bed]. I really want to put this system in my build, but do not want to ruin my flooring on top of it.

@SnowAndCurt 4 года назад

We built our van on weekends over a span of 8 months, honestly... I cannot remember how long we spent on the heater. Yes, the water we reuse can be circulated thru the system without coming out of the shower... so that we can run it thru the filtration system a bit more if we feel like we need to.

Are the heat exchanger plates effected by altitude?

@SnowAndCurt 4 года назад

No they are not. Great question! Our air heater is, we have the altitude kit on it, but no effect on heat exchangers.

@@SnowAndCurt What size is that I'm designing a hydronic system but stuck on how big of a reservoir to install

@keithmccabe3127 4 года назад

I have the same system in my van and have it all operational except the Kalori fan. I can't figure out for the life of my how to wire it. Do you have any pictures or videos of the wiring? It looks like it should be super simple but I can't figure it out. The one wiring harness is pretty straight forward but the second harness I can't figure out. It has a relay in the middle of on one side a single red/white wire with a clip that looks like it should plug into the back of a plastic connector. The other end has a solid black wire and a black wire with a violet stripe. I plan on only using the max speed of the fan so dont need to wire for the the other lower speeds. Any help or pictures would be greatly appreciated.

@SnowAndCurt 4 года назад

Unfortunately, we were not videoing during most of the build. There's oy a few pictures, but none during this phase!

@@SnowAndCurt What is the capacity of the coolant expansion tank? Your parts link indicates it's a plastic tank designed for a Ford. How difficult was it to fit in the engine area of your Sprinter?

@mike.repucci 4 года назад

Hi again Curt and Snow. Another quick question about your coolant loop and reservoir: Do you operate the reservoir vented or closed? I don't see a coolant return to the reservoir on you diagram. Does it loop back to the reservoir?

@radu98012 4 года назад

Sorry to bother. Waiting for my van I try to purchase the needed stuff. I did buy through your website the telescopic leader and it seems a little bit to small for the van. What hight is yours?? I still can return it if it's not the right one. Thanks

Would such a heating system be able to run an in floor radiant heating system?

@SnowAndCurt 4 года назад

Yes! We know that it can, but we didn’t research all of the details for this option.... it would add a lil to the floor thickness... and curt has no room to spare - he’s 6’2”

@Humano321 3 года назад

You would need a small buffer tank to keep the efficiencyof the system, but yes! Def would.

@joekub7 4 года назад

thank you for the info. do you have any videos of your system running? I am curious as to how it sounds, from inside the van and outside the van when running at full speed. I have heard these hydronic heaters can be very loud, so i'm wondering if the volume would keep me awake at night, or disturb nearby campers. any info would be appreciated. thanks!

@SnowAndCurt 4 года назад

We will try to do a sound text and get it in the next video for you guys! That's a great question. In the meantime, it's not too loud... Kind of a constant hum... No where near as loud as a generator. Stay tuned!
