Espar Hydronic Heater Wiring & System Start-Up: D5E Hydronic Heater for Vanlife

Espar Hydronic Heater Wiring & System Start-Up is the focus of this video. We are installing an Espar hydronic heater system in our sprinter van conversion. This is a hot air hot water one source van build, meaning that this system will provide all of heating and hot water needs for us while living in the van. WE had some difficulty finding good installation instruction for the heater wiring, so we have gone over it in this video. And then we filled up the system and fired it up! A hydronic heater for vanlife is a perfect solution and we can’t wait to get it on the road and really test it out!

We're installing the same system in the UK (so Europe) we usually use black for ground and red for positive in 12V systems. Brown is also sometimes used for ground, but the black-coated red wire for the positive threw us off as well, they could have at least used red heat-shrink!!

[ntran]

Thank you for sharing the process. I know how time consuming it is to film the whole process why trying to figure out how things work. I did not see you mentioned in your videos. Did you need to bleed your glycol system? If you did, do you mind sharing how you did it? Thanks again.

Why two heat exchangers? Why doesn't just one work? And could you route them in parallel instead of series?

[Entering.happiness]

Hay guys! I was wondering how long does the water in your shower Stay hot if you’re running it constantly? Since I install my system, I can only get the water to stay hot for about a minute or two before the heat exchanger goes cold and I have to shut it off and let that warm up. This is all while I have the heater running and I have already let it heat up for 10 minutes before turning the water on. Any suggestions could help as well

[alanmoore]

Brown is always ground (and Red is +) on European vehicle wiring based on the Bosch standard. Other 12v systems commonly use Red (+) and Black (-/Gnd). 240V house power systems tend to use Green/Yellow spiral as ground Brown as Live(Hot) and Blue as Neutral at least in flexible wiring - e.g. power cords for appliances.

Question: In the event of a power interruption to the heating system, when power is restored, does the heater come on in the same mode as before the power interruption? For example, if the system is in heat mode and is running, the power is interrupted and then restored, will the heater go into heat mode and run? Ir will it require a person to turn it on?

Why did you use two heat exchangers on your hydronic system and did it work out for you.

[wanderingzythophile]

I'm so glad I came back and watched this video again! I'm in the midst of puzzling out my wiring harnesses for the same unit.

Yours are a little different; I don't have the bigger red/white wire you mentioned, and for a brief bit I didn't think I had the black/red one either - but oddly enough, there's a little black/red wire that comes out of the main bundle, hooks back around and is taped down on the outside of the main bundle where the model number label is. I suspect this wire has the same use as yours does, so I think I'm going to try it with my Kalori air matrix/Webasto controller as well.

That said - how did you guys manage to keep air heat going overnight in cold conditions? You say this one wire will prevent the Kalori fans from blowing when there's not enough heat in the system; does using that wire make the Webasto controller cause the main hydronic furnace to kick on and heat the glycol? Or does the main furnace controller have a timer you can set to run for a few hours as needed?

[rmpage]

I'm from Germany and the house installation is brown or black for the conductor and blue for the neutral conductor

and in the 12 and 24 volt range, red is for the conductor and black for the 0 conductor

[tipatses]

Hi ! I've just start running my Espar D5E S3 and even if I select "Infinite" time running on the Easy Start Pro, it stop every time after many hours ( Fault code P000e01 : Runtime limit exeeded). Do you had this issue with yours ?

[rogerlittlejohn]

what fittings did you use to hook the calorie fan to your (orange) coolant line? looks like 3/4 shark byte elbow then what? Thanks.

[christiansthilaire]

You mentioned black and red on pin 1. Is that the pin that says un-used in the webasto instructions?

[austinmabry]

Hard to tell from the video, but you're not running straight propylene glycol in the system, are you?

[michellearneson]

So what is the coolant for? Did you say this heats water and warms interior of van?

[thecodingworkshop]

Here in the UK on a single phase system i.e 240v we use brown=live, blue-=neutral and yellow/green = earth or as you guys say ground.
in a three phase system i.e 415v we use brown/black/grey all live conductor and we would normally use the black as ground wrap in yellow/green sleeve if that cable is part of a 4 core cable.

On the DC side its typically black and white core where white=positive and black=negative

[Joe-nxnj]

im building a sprinter and i am thinking of going in the same direction. how has the heater held up? also how has it been for hot water ? its hard to decide between this and two individual systems

[jsj]

Yikes! Amazing job figuring that out. The smile on Sandy's face when the thing fired up... priceless. Quote of the day: "And yet... another perfectly good hole in a perfectly good van." Thanks for the education! -Burt in NJ

[cluek]

Congrats! Looks like you are luxuriating in space for these and plumbing connections. (Next build, I’ll bet you design space-use tighter)

[tipatses]

Nice video ! Very helpful ! It's me or the Kalori fan blower sounds very loud when running at 17:55 ? Or maybe it's because the camera was to close to it ?
