There's a chance I could fit a 30.25" tank but it will be tight. Mounting the Propex about 1.25 inches rearward would simply encroach upon 1.25 inches more of (the bottom of) your underseat storage.

Looking good. Love the rubber mount idea. I screwed mine right into the panel. Looking forward to see the finish under the bench seat. |

I am going to do the same install in a few weeks, just ordered the 2211 today with grommets.
A question; I'd like to mount the 2211 and a 2nd standard LP tank on the passenger side. I've looked through the 2211 threads and was looking to find out if anyone has done that - or if it's possible. I couldn't find anything definitive.
Looks like there is room - needs 30" - but thought I'd query. (Our van is down south so I can't measure it )

In this pic you can see the back studs for the tank, you'd have to make a bracket for the tank if the propex was in that same spot.
I had a look at a friends a couple of weeks ago and there isn't enough room the way he has his mounted.
There is roughly 54" in that space and when the tank is mounted in the correct position from the back cross beam to the end of the tank in the back is about 11.5"
You'd have to take in consideration the frame tapers in the front too. |
Timwhy thanks for pointing out the existing mount holes. I didn't realize they had a stock passenger side location. Sounds like I'll have to mount the tank farther forward if possible.

Thanks Sodo, I appreciate the time to lay that out. Looks like I better plan on spending some time mocking it up before drilling any holes. Will have to consider the loss of underseat storage too, not an easy choice! _________________ '91 Westfalia, Bordeaux Red Pearl 2.1L 2wd Auto

I try to balance all the plusses & minuses. The Propex (& 2nd tank) fitting into a previously un-accessible space is a significant victory that is worth the loss of a little underseat storage IMHO. _________________

I agree, the passenger underside seems like prime real estate and it would help offset the full camper load issue too (which will keep us from circling the country to the left )
Having the van down south and not in the garage is a bit maddening, but at least it's forcing me to have my ducks in a row. Only have 5 days and don't want to get halfway installed and run into that "oh s***, that's not gonna work!" moment. Thank you for the info!
Oops, another question. The silicone you used - anything special? And any bare metal treatments added? I can probably find anything I need in the Tacoma area, but having it there before my arrival is even better. _________________ '91 Westfalia, Bordeaux Red Pearl 2.1L 2wd Auto

>>>>The silicone I used - is it SPECIAL? Only that it's BLACK.
Today I started on a guard for the propex heater.
Welded of rectangular steel tube.
Mounting tabs are 1/4" and 3/16" thick
I used Riv-nuts for mounting - I like rivnuts. These are M6 size. I hoped to use M8 size but M8s won't fit in the center frame rail (see middle photo above) because there's not enough "depth" in the frame-rail assembly for the height of the (un-collapsed) M8 riv-nut.
I coated them with sealant before shoving them into the hole. I used "Permatex Ultra Grey" which sounds like it might be so ultra gray that it's black (but it's just gray as all good getout ).
Using a home-made manual rivnut setter. I keep putting the official tool in my Amazon shopping cart but fail to buy it for some reason. Then I use this home-made rig again, and it works fine, and I forget to order the official tool.
Heres the 5 mounting points.
I will add a blast fence for rocks tossed up by the the front wheel.
Planning to cover the bottom with expanded steel. That's tomorrow! _________________

Do you put your Riv-nuts in wet with paint on them for corrosion protection? _________________ This free advice is worth exactly what you paid for it.

Sort of - I put them in wet with Permatex Ultra Gray. Hoping it seals up against the bare metal holes (for corrosion protection).

Could I ask about road spray? Propex states in their documentation that although the unit is sealed and made from corrosion "resistant" materials it should be fully protected from road spray.
My experience with Wet and snowy\slushy roads is that the underside of the van gets plastered.. literally. Especially in line with the wheels. Even my drive shaft protection bars and shaft itself get coated with sand\salt and Ice. I would be extremely nervous having my heater hanging down there. Any long term feedback? |
Apparently it's made for under-vehicle use, but probably not intended for a direct, forceful water blast. A forward-facing 'fence' seems necessary. On my list is a cargo carrier (forward of the heater) that will protect it from stuff coming up from the front tire. No longterm feedback yet!
Does anybody have a Westfalia heater box they'd like to sell? Especially in Seattle? Please send a PM directly. _________________

OK I got the guard done, and installed.
Someday I'll make a cargo compartment for the area (ahead of the heater) that will shield it from rocks and spray off the front wheel.

Got a question from a member that I didn't show the final warm air outlet. He;s right! So here it is.
Heres the ducts coming up from below into the rear seat storage area. I have not yet built my intake screen/box. The return air just comes in around the gap under the seat.
Dimensions where I cut my hole. There's a 3/8 in just about every dimension on this job. I don't know why.
Warm air. Normally you want your outlet far from the intake. But a van just doesn't have that much space. So here I'm hoping the moving jet of airflow gets the warm air AWAY from the intake area. It seems reasonable,, it's a lot of air moving fast. _________________

i solved this similar, but i put the heater away from the door to the driver side of my split to make sure i am not heating the outside. _________________ regards

I made another guard, mostly just to practice welding aluminum. I hoped this Aluminum unit would look better, lightweight and rust-free.
Hers a pic of the "old" and the new.
The gray is the steel guard I made in 2016.
Silver is the Aluminum unit (made today).
Some of the welds are nice. It's aluminum wire-feed, with a spoolgun, and the sq tube is .120" thick.
Most welds came out OK, but the three VISIBLE welds, are gloppy, dangit. It's strong cuz welded on both sides, but the three worst welds are visible under the slider door. If I did it again I would weld only the backside.
Sometimes the MIG welds easy, other times, with no apparent difference in method or preparation, it "welds crappily". Also I can't discern a weight difference between the Alu and the steel version. _________________

I'd make another if you are happy with welds like what you see here cuz that's all I got. They could be better or worse. It would be plenty strong enough just welded on the backside (omitting the visible weld). Steel is easier, but then you have to paint it. Send a PM if interested.
Maybe a guy/gal could use the guard to support the Propex (rather than screwing the propex up to the bottom of the floor). You'd have to do a little further fabrication to attach the Propex to the guard. You can get aluminum shapes at HomeDepot and use self-tapping screws (or tap the holes).
Would be interesting to compare the sound/silence of mine (rubber mounted) to a Propex that's solid-mounted. _________________

Anyone else who has done this mod, or is planning to, and wants to get a rock guard from Sodo, PM me! I'm doing it this spring, and think the guard is perfect. Best spot for the Propex, and way too expensive and time-consuming mod not to have it protected properly. _________________ 1990 Syncro 16" DoppleKabine 2.1 DJ 112i

I know a guy who did the Westy - passenger side additional storage 'box'. It required cutting out the floor...but he was able to put his propex, and aux battery in that storage box. _________________ Brandon

I made four of these Aluminum guards, sold two last spring.
Today I finished #3 and posted in the classifieds.
https://www.thesamba.com/vw/classifieds/detail.php?id=2343655
I'll put the last (aluminum) one together soon if anybody's interested.
It's a little 'less attractive' than #3, but does the job under-the-van.
These seem real simple, but they take more time to build than steel. _________________

Installed 6 years ago (2016) my Propex 2211 is putting out less heat than I recall.
I have a new Marshall regulator and propane pressure measures 11" WC.
TODAY, this evening the outside temp is 45°F.
Running the Propex:
thermostat knob at max
for 45 minutes,
westy camper top closed,
the inlet air temp is 165°F
The temperature in the van is 65°F
I'd like to get more heat out of it.
65°F inside is OK at 45°F but it took a long time to get to 65.
I'd like to be comfortable when it's 20° outside.
Apparently the outlet temp should be around 200°F so I'm certain that it's not putting out full heat.
Does anyone have suggestions to restore performance? _________________

I've managed 180* F entering the van from my 2211 after adjusting the propane regulator. 200* F would be nice but I think we might be dealing with a heater that has limited capacity to heat the van.
The Propex is amazing in cutting the chill and I appreciate that a lot! Although I'm not sure if it's up to the task of converting 20*F outside to 65* inside. I've been considering a CDH for at least several years as a replacement. Syncro Jael did some comparisons a few years back that showed the improved heating capabilities of a CDH.
As for your questions, Karl at WestyVentures or the gang at RMW may be able to provide tips for restoring your out-of-the-box performance. You're one-step ahead in measuring WC.
