Just become the owner of a Eberspacher BN4 petrol heater with various bits of ducting etc, and have been told it works. The first thing to do is to give it a test run, safely outdoors to see if it actually fires up and performs as it should There's plenty of info HERE Then I can think of installing it. Pictures on the web suggest it should go to the left of the engine compartment, but this would require removing my second battery (opposite side from the prime battery). Zed has successfully installed a different type of petrol heater inside a T2 Westy cupboard. I wondered whether a good place to install mine might be under the rear R+R seat rather than in the engine compartment? The recommended ducting seems complex but the underseat idea would simplify installation rather. Any other suitable places? There is no solid exhaust pipe, which must surely be needed, but otherwise the kit seems reasonably complete. Anyone know where spares are available? I'm looking forward to the project
No he hasn't, must be someone else. I chopped out the spare wheel well so I could have it higher up and also have a leisure battery, but it's in the engine compartment. Perhaps you could adapt the ducting and do similar.
I have stuck mine in the spare wheel position but piped it through the engine bay then into the rock n roll bed then out the front of it
Ah, must be someone else starting with a "Z" - Zebedee - http://thelatebay.com/index.php?threads/how-to-fit-an-eberspacher-heater.391/#post-3312
Mine is in a similar location to under the bed, maybe not so far back, (its in the crewcab) it pipes into the heater pipes under the front floor
Goes through the bulkhead as in pic 1 then out the front of the RnR bed, i use it as an extra, not plumbed into the original, but i guess you could go through the floor into the existing pipe from inside the bed
Mine is under the rock and roll....I don't have a clue how it works though, as I've not had it running! I have the instructions though :0)
Well, the Eberspacher was tested on the lawn today and fired up beautifully. Just ordered a load of hose (NON braided SAEJ30R9 ), filter, fittings etc etc for the fuel supply -£50 so far and that's just the fuel supply! Just a thought before fitting it. The supplied ducting kit takes the warm air through two bulkheads, past the tank and out under the rear bench seat. Would not a better system be to introduce this heated air into the existing heating system so that instant warm air could be applied up front. Just where it's needed, and a quicker way to demist the windscreen?? There'd need to be a flap, to close off the existing system before it reached the "Y" junction, so that 1. When the engine was off, the Eberspacher recycled warm cabin air only and ... 2. The flap opened when the engine was running, so that the normal heater system worked but the Eberspacher system supplemented it when required.
Mines as it was intended works luvly stick it on when we get loaded then switch it off as it's so toasty in the van Don't forget about the ebers exhaust some have the recirculating bit don't think mine has that. mr @davidoft is the man in the know.
I'll probably go the "remove the spare wheel well" route as suggested above, to allow the second battery to remain. Cutting through the bulkhead seemed daunting at first,but the article at http://type2.com/rvanness/caspbn4.htm suggests it's not too difficult. A case of measure twice cut once, and if there's a smell of petrol RUN!!!
It's a different model of Eberspacher, and looks the perfect place for a supplementary heater. What's the black corrugated pipe in the background?
Here's some pictures of mine I just installed. Let me know if you have any problem because I've had to fix up three of these now and I'm getting pretty good at it lol. I've also got some spares so let me know what you need
I've not had a proper look at it yet... weather has been hanging here, and I only picked the van up last Friday!!
It's a BA6, I have one on mine which wasn't working correctly but after a bit of investigation i know get complaint from the children about being to hot
I don't think you need to remove the spare wheel well to fit the battery, the heater itself is fairly easy to pop out to change the battery
