Disclaimer* We aren't professional “Van converter people '' so this is our experience with installing a hydronic heating system. There’s no one way to do this, and it never hurts to check out other content/professionals to get a second opinion. *
Speaking of other people’s content, we got inspiration from a few other KZfaqrs, and would like to thank them!

Anyway, this is our install of the D5S Hydronic heater from Heatso, which has been tested and is up and running!
We chose the D5S which is compatible with a high altitude kit, because we sometimes camp at elevations greater than 10,000ft. For most of you, the newer model D5E is a great option. Luckily for you, almost all of the installation process is the same, so follow along, and we’ll point out any differences.
You can grab yourself a D5S or D5E over at Heatso!

You might be overwhelmed by everything that comes along with your kit, but if you go step by step, it all starts to make sense. We started our install with all the components that needed to be installed on the exterior of our van. Here’s a few of the items we used in order to do that.

Makita Kit: amzn.to/3uNOHkE
Thread Lock: amzn.to/3LsCOqh

For many of you with newer vans, you may already have an auxiliary fuel line installed. All you need is a quick connect adapter to tap into it. Here’s the link for the supplies you’ll need to tap into an existing line:
AUX Quick Connect: amzn.to/3HPeYTi
AUX Quick Connect Tee: amzn.to/3GMlNUq
If you’re unlucky like us and you need to install one, you'll need to drop your fuel tank and pop it open to run the new line.
¼” Hose: amzn.to/3BkCeGr
¼” Loom: amzn.to/3Bgaa6Z
In order to run our glycol lines from the heater to the van, we needed to measure and cut holes in our subfloor.
Hole Saw Kit: amzn.to/3gLsf3c
Cable Boot: amzn.to/3gKZnYR
We had to purchase several fittings for our Two Pipe system. Here's a few links to the products we purchased.

The wiring requires a few special tools.

We purchased a premixed propylene glycol product called CryoTek 100. Use the table on the jug to determine if you should dilute the mixture, depending on the length of your system tubing, the size of your lines, and the temperature you want your system to hold up to.
CryTek 100: tinyurl.com/4m832t26
With our lines hooked up and every component wired, we ran a test of the system.

We’ve tested the heated floor and the air matrix a few times and they seem to be operating well. We don't have our water lines hooked up yet, so we plan on putting out a full review detailing the efficiency of the system and energy/diesel consumption in the future.

Consider putting some sort of bug and debris filter on the end of the intake and exhaust of the furnace. I used stainless steel washing machine lint filter for the intake and the exhaust came with one. It would probably be "bad" to get something crawling or sucked into the furnace. I really enjoyed watching your installation. You do a great job.

I just added a floor heat loop to my Espar D5WS. Bypass with just three standard ball ball valves. One ball valve on each leg going to the floor heat loop. One ball valve in the center of the bypass. To add the floor heat to the glycol loop, open both ball valves and close the third ball valve in the center. This will allow glycol to flow through the floor loop. To bypass the floor loop, close both vlaves going to the floor loop and open the third valve in the center of the bypass. Easy peasy, commonly available valves from any hardware store.

As you have a twin line water feed, why did you need the three way valves for the floor bypass? I agree if you have a single line system you would need this, but with a twin line system all you need is a single on/off valve to shut the floor loop off in summer, especially since your bypass leaves liquid in the floor loop so really no benefit with the complex bypass setup. It may even cause issues as this will allow hot water to flow via the least resistance path through the bypass valves back to the heater causing this to regulate (reduce output) or even maybe shutdown. Sorry if I’ve missed something here, but I’ve fitted a few of these Webasto style heaters on several vans.
@dogcatmanvan 2 жыл бұрын
You’re probably write. We’ve received a few comments suggesting the same thing. This was our first go at a hydronic system so I figured a bypass is what we needed, but I can see how a simple shut off valve would do the same trick. Wouldn’t the fluid still sit within the heated floor loop though? Or would the pump pull it out once the heated floor section is cut off?
@theonlywoody2shoes 2 жыл бұрын
The glycol fluid will “sit” in the floor loop, but this really isn’t any different to the fluid sat in the header tank; it doesn’t “go off” or anything just sat there. Think of it like an electrical circuit with a switch disconnecting either the positive or negative connection to the battery - nothing flows until you turn the switch/valve on (I guess you could say that in an electrical circuit the power is just sat there, waiting to flow once the switch is turned on too). The pump won’t suck the fluid out of the floor loop, as there is no pressure created, the fluid will just circulate via the plate heater for your hot water and the air heater matrix instead - that’s the great benefit of using a twin feed/return design as you have. Those circulating water pumps don’t make a lot of pressure either, as they are a different design to the pump you have for a faucet on a sink. They were originally designed for use as engine pre-heaters in cars/vans/trucks, so the electric pump circulates the engine coolant fluid when the heater is running, but allows the coolant to flow through it when the heater is off but the engine (and its coolant pump) is running. I hope this helps you understand things a little better.

There’s a bit to it, but the premise is that a tiny microprocessor called a Wemos d1 mini turns on and off a relay that turns on and off the heater. That microprocessor talks to another small computer called a raspberry pi. That runs home automation software that talks to the iPhone through HomeKit. So when you turn on the heater through the iPhone, it talks to the small computer. Then the small computer talks through the vans WiFi to the microprocessor. It’s way easier than I’m making it sound. Then when the van gets to the temperature set by the iPhone, the relay turns off and the heater shuts down. When temperature cools down the reverse happens, and the heater turns back on.

I agree you should have spaced the PEX in the floor closer, I also would have heated the entire floor even under cabinets, benches, that way the entire floor becomes a radiator. Just remember space heating is not just heating the air inside the van everything inside the insulated envelop is being heated, counters, cabinets, the sink, the bathroom, everything so having the underfloor PEX running under everything helps heat the entire space. There should also be heated floor under your freshwater tank and batteries/electronic for obvious reasons. draw the exact path the PEX in the floor takes on the top of your subfloor so when you are mounting cabinets or 80/20 modules you will not pierce the hydronic lines.

You don’t want the fumes creeping in every nook and weeping hole under your van. I went with Rixen's Hydronic heater and after seeing your video I am glad I did, so what you talked about at the end is not an issue with Rixen's. Hooking up all the wire was dramaticly simplified and you don't need to do near as much work to integrate all the wireing end points. The support you get from Rixen’s is superb! Really more than half the time you get Jim Rixen on the phone and he is happy to help the DIY folk. I actually think he likes being on the front lines so he can hear the issues first hand. I wish I had decided on the Rixen's system before I completed my flooring. No in floor heat for me.

I put one of these in my van and thought I might regret putting in the heated floors. The Kalori blower that comes with this system is SOOO loud I scrapped it and put a Chinese diesel heater under the passenger seat floor which has worked incredibly well and from the back of the van I can barely hear the heater even on high. I went skiing yesterday and camped there the night before. Temperature was 8 degrees F. We actually didn't have the heat on all night and woke up to a pretty cold van. I turned on the diesel heater and it just could not seem to warm up the van comfortably. When I turned on the floor heat the van heated up quickly. So long story short I would definitely recommend the floor heat because the floors get really cold and just having an air heater might not be enough. The chinese diesel heaters are cheap so would recommend going that way instead of the Kalori blower.

RE the floor, although I don't know the best way, the problem is that you don't have enough tubing in the floor. I would lean towards trying 1/2" tubing, to slow the fluid and enhance heat transfer, and lots of it. The pump might be too light for smaller tubing and you would just increase the length. The spacing is way too far apart.
@dogcatmanvan 2 жыл бұрын
Yeah we came to that conclusion at the end of the video. We are using 1/2in tubing for the underfloor heating. They definitely need to be closer together, but I also think the flooring needs to be different. I wonder if I could've gotten away with 1/4in subfloor, but who knows if that would make much of a difference.
@NoOne-xp1pe 2 жыл бұрын
@@dogcatmanvan As nice as a warm floor is, I'm thinking all solutions lead to a lot of work, added weight (bad mileage), and slower heating. Perhaps adding more radiator type with or without fans would be more practical. A long radiator without fan could hold a good volume of heated solution, radiating heat while the pump is off. You're kind of asking the same of the floor, but you have reduced radiation, and only a hard surface will keep the heat, giving up more space and increasing the weight even more. Interesting build, good luck.
@kaymarpee 2 жыл бұрын
Not sure how far along this van is but a possible adjustment could be made at this point. You can router out grooves on top of the subfloor and place flooring directly on top of the tubing. That’s my plan- I’ve got these layers 1) furring strips with insulation on top of the van metal floor, 2) 3/4 inch ply resting on the furring strips 3) pex tubing inlaid into the top of the plywood via routered channels (the pattern of the furring strips should support the ply, I’m using 3/8s pex), 3) cali cork plank click lock flooring floating on top of that....click lock floating should reduce any problems from floor expansion changing temps

Be sure to place the plates upward to help spread the heat on your floor material. Again, love your ambition and common sense.

@brutusmaximus5380 6 ай бұрын
@@dogcatmanvan If you are going for heat conduction through solids, I suggest copper foil adhered to the underside of your wooden top floor. However, you would have better results with ceramic tile with a copper foil underside. Copper is expensive. Aluminum may be cheaper and it doesn't corrode in a humid cabin but since it's near the top most layer, condensate from the cold metal floor would be negligible. Most of your heat loss is coming from your air matrix and the heat exchanger since they are the 1st in line and that's why the rear of your van is much colder. I'm going by Bernoulli's' principles of fluid dynamics here and looking at your diagram, the pass through connection from the heater to the heat exchanger looks like it's going to suck in the colder fluid from your reservoir, through the heat exchanger and mix it in with the heated fluid coming out of your heater but that's depends on the pressure difference between the heater and the outlet of your heat exchanger as well as the amount of flow resistance created by the heat exchanger. What I'm saying is that the fluid flow through the heat exchanger looks like it would be opposite of it's intended direction in the diagram. I would have connected the heat exchanger, air matrix and floor line in parallel. But it looks like that single pump has enough negative pressure to keep the flow in the proper direction.

The point of the heating floor, is that is working when loosing the temperature, so you never should put insolation, between the tubes and your floor, you always have to put it under, to avoid lost this temperature from the bottom. The floor should lose the temperature from the top, and the temperature that the floor lose, is the way it works to warm the air. For that you need a surface with a high thermal inertia, so it take a lot of time to warm the floor, but after that it will be really efficient, because you will need a small amount of energy to heat the area. This type of heating is not the best for vans, because you are switching on and off all the time the heating. the heating floor in a house, normally have a first period that it need a lot of energy to warm the floor, but after that just a small amount and also it takes 1 or 2 days to have the proper temperature at home

Nice! I don’t have the same stuff, but my air heater does have a valve on it to make it hot or ”cold”. On my heater in outputs do matter. I didn”t see any valves on yours so you should nit care about direction. My floor lines runs roughly 20 cm apart from each other. Even after a whole night running you still feel colder areas in between. Lack of concrete😅 I insulated all my pipes as they do heat up quite a bit. And try not tu build to much stuff around as you always want to check your system!!!had 2 month great than started leaking...you never know on this diy systems. Btw, i only use the fan to warm up quickly,than it only maintain heat via the floor, really nice. Had this weekend -3C out and staedy 15C inside. Wish you both all the best. Cheers

The reason it's more efficient to only have the one line connected in the expansion tank is that you are not circulating the water THROUGH the tank, which would have all of the hot water going into the tank, and leading to heat loss. If the only water that enters the expansion tank is the water that 'expands' out of the system due to heat/thermal expansion (hence the term), then it doesn't expose all of that heated water to a poorly-insulated tank that will just radiate and conduct the heat away. In times when you're trying to heat the space (ie; winter) the losses probably won't matter too much since most of the heat will be lost inside the living space anyway, and just contribute to the overall effort. However, in the summer months, losing heat to the interior of the van not only hurts the efficiency of your water heating system, but also creates more work for your cooling system, causing both systems to work less efficiently. I'm surprised nobody was willing to provide an explanation.

I would warn against tying into the existing high pressure fuel line. I would also run the wires, then build the harness so you can get wires through smaller holes. Looks cool.

From your neibor to the north. I did not see any isolation valves on either side of the circulation pump. They are very good to have when you have to replace the "water" pump. No need to drain the system . Have a nice day. Tom up in Canada in the Maritimes at the NB-NS border.

Thank you for putting all of this info together! I know this isn't a recent video, but hopefully you see this comment. Was there a specific way you purged the air from the system? That seems important with the 2-pipe layout and only one port leaving the expansion tank. I've basically replicated your system, and im ready to fill with Cryotek-100, but I want to avoid getting airlocked.
@dogcatmanvan 3 ай бұрын
Hey there, your expansion tank should have a breather line towards the very top of it to allow for the air to expel as it cycles through the system. The only way we were able to successfully purge the air was to run the system and take the van for a drive. Hitting a few bumps and vibrating the system while the pump was running worked the air out of the lines. I drove while Julie kept an eye on the expansion tank and she was able to visually see the air bubbles coming up. The air wasnt really purging itself before we drove the van. Hope that answers your question!

Very nice to see you have made the hydronic system working. I did the hydronic system in my sprinter 4x4 with single loop system. Floor does not get hot but it is warm enough to walk on it with bare foot when out side Temp is below 20 degrees. Do you have any issues with not controlling the fan speed. I can not control fan speed on my setup. other than that heater works great.

We've been able to control the fan speed thus far. It's a bit delayed when switching between speeds, but it works fine.

I know this is really old. But I’m thinking a 3-loop manifold would really clean up all that plumbing. One loop serves the heat exchanger, next loop serves the air matrix, third loop serves the floor heat. Easily isolate the floor heat at the manifold for the summer months.

Built Hydronic floor , using 1/2 inch pex , routered into 2" XPS with aluminum dissipators sandwiched in place. The length of tubing is critical. 3/8 can actually deliver enough heat (and bends easier ) You need to be able to dissipate thru the floor. Your test with the Aluminum fin up failed because it is such a short tubing and not in direct contact with wood floor , ( needs to be stapled but that is impossible with pipe already in place.) 100 feet of tubing is closer to what is required for X,000 BTU heat transfer. (to get the effects you were expecting.

Hey guys! Are you functional with the heating? We purchased from Heatso the espar D5S, the Kalori EVO1. It was a kit, we just bought that as it was listed. Buyers remorse. The Kalori doesn't get very hot, the D5S only runs for 3 programs for 120 minutes each. Not thermostatically. The Kalori only raises the temp 10 degrees over outside and it is so loud you can't have a conversation. Heatso not helping at all. 3000$. 😿 Hope anyone reading this will save themselves the grief. Not Heatso, Not a D5S. Maybe we have a bad Kalori. For sure the D5S is a disaster. If you are cold weather camping, thermo control is essential. Hope to hear yours works perfectly, and maybe then we can get a warranty replacement.

Yes we've been utilizing our heating system this winter. There is an override setting that you can find within the instructions that will allow you to set your heater to run for as long as you need. We will do our best to include a video showing our thermostat hookup for the system before we are completely done with the build serious.

Our purge line just runs underneath the van and when we want to empty the lines we just place a bucket underneath it. Other than that, it's not attached or running to anything.
