Propex HS2000 VW T4 Install Gas Heater Camper Conversion Propex Installation Guide

- In this video I show how I install my Propex Heatsource HS2000 Gas Heater in my VW T4 campervan conversion (See links below for Propex heaters). The videos covers the full Propex installation from start to finish including cutting holes in the floor panel for the Propex HS2000 pipework to sit in, running the gas pipework to the Propex unit, installing the intake & exhaust pipes, completing the Propex wiring and test firing the unit to show it working.
After I finish installing the Propex HS2000 unit I build a box unit around it to help reduce the noise of the fans and to hide the unit away so it doesn`t get knocked about. Now that I have completed the Propex install I will get it checked over by a motorhome safety engineer along with all the other gas connections and electric hook up. When carrying out any gas installations, whether they be for the Propex, fridge, cooker etc please take a safety first attitude and get it checked once complete.
I hope the video of the installation guide of the propex hs2000 was useful and if so, have a look at my channel for more useful videos.

Those heaters are loads smaller than what i thought.. and the noise wasn't too loud either. Excellent video for showing us these 2 important features
Great explanation its given me a good insight how it all works thank you very much 👍😉
Glad to be of help
Thanks for the video, I'll be installing mine soon
Glad to be of help
You might want to use more than zip ties to secure the copper gas line as well as using some kind of dampener between the copper and the body metal. Vibrations will be rubbing holes in it.
Good video well done 👍
Thanks, nice straight forward install
Thanks great video
Glad it was helpful!
Hi
Thanks
Any follow up vid planned after x hours of field i.e.?
I love the video. I would be a bit nervous about those gas pipes underneath though. If you ever bottom out the van, it could be a world of hurt. Bringing the pipe through the vent was a stroke of genius though. Brilliant idea.
Thanks, I''m not concerned about the pipes though as they have been secured high and tightly to the main beams running down the van so are probably well over 40cm clear from the ground and above the sill line which would bottom out first, although I can't see that being a problem anyway, the van isn't lowered and will be getting larger wheels too
Great videos you are putting out! I was also concerned about the pipes under the van, my thought was that running the copper pipes that close to the beams could have them rubbing and wearing out over time which could also me a major risk. I would have slid some heavy duty hose over spots that could rub against the van. Just my thoughts though, as I said great videos!
Thanks, a bit of hose would be a good idea but caravans have exposed piping mounted underneath in the same way as I've done so I can't see there being a problem
Do you recommend a pressure regulator that will work with the propex heater?
It says in my manual that came with the heater that the holes are supposed to be 40mm for the exhaust in intake pipes. That does not make sense to be as the pipes are around an inch.
Great video. Thanks. Given me more confidence to have a go myself.
In regards to wiring, for power did you wire it to the thermostat controls which were connected to the control panel which in turn is wired to the battery?
Thanks, Wiring for this model is very simple, there should be 2 cables from the unit, 1 for the thermostat and the other should have red & black for the power. Just wire the red & black to a 12v (fused) power source and thats it, I only took the thermostat apart to run the wiring from the unit up behind my panel and had to poke the cable through the panel.. I have ran the 12v power to my main switch panel first before connecting to the unit but this isn't needed as the thermostat had switches on it too, I just wanted to be able to shut the unit down if the cool down fans were running for too long. If you're still unsure on the wiring, have a look at my channel as I have a video where I test this unit before fitting which shows all the cables
CamperConversion ah great very simple then. Thank you. If I'm honest my main concern is drilling holes through the floor of the van.
I was nervous the first time I had to do so on my last van for the gas pipes & drop out holes, just start with a small drill bit to make sure its gone through in the right place, then use a hole saw to widen it out as required, treat the metal and job done. This van has had 8 holes put in the floor and 18 in the roof so far
Hi, do you have to run the gas pipes under the van, would it be possible to use hose? I have no knowledge of these things , really enjoying your vids
Thanks
The pipe doesn't have to go under the van, I just ran it like that as my bottle locker was the opposite side of the van and wanted the pipe under the van so its out the way, flex pipe should be avoided if possible as it can perish, split and leak over time, copper stays solid.

Thanks for the reply
From other videos and Propex themselves I'm under the impression that the air intake and exhaust pipes had to be the same length to keep the unit in calibration. You showed where you lengthened the exhaust but didn't say anything about the intake. Yes/no? Maybe the states have different requirements. I'd also replace those zip-ties underneath the van with real clamps. Zip-ties will vibrate and cut/break through.
I emailed Propex who said there was no issue in extending the air intake and the system has been used multiple times since fitting and its worked 100% every time.
It looks like the floor of your van is wood and possibly insulated. My van has 1" of polyiso covered with plywood. Does the combustion exhaust get hot enough that it would be a hazard?
I would not think it should not be too much of an issue considering these are made specifically for campervans/motorboats etc where they should know there might be wood/insulation involved but if you are ever unsure on Propex matters, just email them, they replied to every question I asked when I bought my first unit and were more than helpful even though it was discussing a model 10+ years old...
Is your power source a dedicated 12V battery? If so, how long to you think it will provide enough current to operate the fan?
+Raven Feather the Propex is wired to my 2x110ah leisure battery bank which is topped up by solar panels so I can't see my batteries running flat anytime soon but I think the draw is about 1.5a per hour
Thanks. I know zilch about electricity but that should be enough information to figure out how long it will take to draw down my battery the recommended max. After I take a look at the battery for specs.
I'm currently using a Buddy Heater and it does a good job here in the mid-west although it's either on or off (it's not thermostatically controlled) and it can actually get uncomfortably hot in my small rig. And in the Rockies at higher elevation the windows in my rig have to be open in order for it to get enough oxygen to stay lit - which kinds of defeats the purpose of having a heater. The installed heater sucks too much juice if you're not hooked to shore power and it's very loud.
Just get a good sized leisure battery and it should last a long time, if you get a 100ah battery and the heater was left constantly on at 1.5a, the basic maths says the battery would in theory last 75 hours (although you're not supposed to run a battery flat, voltage drop etc) but the heater wouldn't be drawing that all the time, only when running until it clicks back off again. If you're driving you could get a split charge relay to charge the leisure battery while on the move to keep it charged up or a solar panel stuck to the roof like I have.
Can the gas hose be a rubber flex hose? And will the heat from exhaust char the ply floor?
It should be copper for safety sake and I didn't notice any effect to the flooring
Hello,
I just bought one but I don't know what gaz regulator I have to use with it... I have got a 50 mbar gaz regulator should it work? If not, please let me know which one I should get... Thank you
Generally 30-37mbar from butane or propane bottles, should say on the unit or on online instructions for it if it will accept other pressures but I think the 30-37 range is whats its designed for
@@TheCampervanBuilder I'll do it. Thank you for your quick response!
I've got one of these. Can not get it working. I'd go for the diesel heater instead.
Contact propex, their support is superb even on used / older models
Had to smile when I saw the exhaust pipe fixed with plastic cable ties... bet they wont last 30 mins when the heater is running.
Well the heater has been fitted over a year, used multiple times and the ties are still as they were, I used stupidly large heavy duty ones
I can't get mine working it's just flashing red I've plenty of gas to ie blue bottle 😊
Contact Propex directly, they offer excellent support on their products, whether bought new or not
Howdy Folks who might choose to do this for them self’s ....
Suggest using a metal attachment for the exhaust pipe of heater.
This video happens to demonstrate us of plastic zip ties... will melt.
The exhaust pipe is metal and the zip ties are only used on the cold air intake so will not melt at all. Maybe watch it again it more detail
That’s a lot of soft copper pipe under the van 🤔
That there is, but of which is all securely fastened to the bodywork and is no different to a caravan gas pipe setup as they also have bare copper pipe running underneath.
Great video, thanks! But you talk as though you are singing 😳
