What is the difference between the B2, BN2 & BN4 Eberspächer model heaters? I see several on eBay and I would like to buy one for the 66 Camper that I have a deposit on (still waiting for the title). I also see on this Samba site several for sale so perhaps it would be better to buy from this site instead of eBay. I found this really nice site with lots of info on the heaters http://web.telia.com/~u11107929/html/heating.htm.

Do these run on gasoline or diesel fuel and how safe is that? Which model should I look for and what should I look for? If I buy one and it needs repair is there a place or person anyone suggests that I can send it to for a complete rebuild. Or should I just buy the new heaters that have been listed (I think they are different fuels).


Thanks,
Linda

Where on the east coast are you? If this guy is still alive he's a source of answers to all your questions and will have the BN4 you need. He called himself "Meister Betrieb" but his real name is Ark Mirvis. He's in Hapotcong, New Jersey at 201-398-6363. This info could be old as I haven't contacted him in awhile. On the west coast there is Crofty, I believe, here on TheSamba.

the matching heater to your bus is the BN4, I'm currently restoring one for my 67 westy and it's funny and I'm learnig alot.
They run with gasoline, they took it from the tank. This heaters are safe if they are in good codition and if you pay attention to maintenance. New Espar heaters are expensive...
This issue is covered in lots of threads...

Thanks for the help I am looking at a few heaters for sale but I would rather a refurbished one that I can trust even if I have to pay a lot more for it. If you or others know of where I can find a refurbished one let me know.

I am going to have to wait a few more months for the title for the 66 Westy because they have not files on record but as soon as the DMV says it is in the process I'll pay the rest of the monies as the owner in loosing his home due to foreclosure and he could use the cash as he had to put the bus in storage for me.

My dear father just passed away on Friday and the Samba keeps me from being so sad.

How do I post my picture of the Westy?
Best wishes to all,
Linda

I will restore the one I purchased to get some spare parts... But I thing shipping from Europe isn't a good idea.

I think Crofty refurbished some BN4s and sold it with factory specs settings... So you know what you get is a working unit...

I get mines from ebay.de.

I'll fix my exhaust this friday... I think this shouldn't be the hardest part to fix in a BN4... Pipe+welder

As time went by the company made changes/improvements to the heaters. The earlier ones with one glow plug do not fire up as quickly as the later ones with a glow plug AND a spark plug. Some have carburators. I don't know all the differences.
They do run on gasoline, just like the gasoline that the engine runs on.
Is that safe? No, gasoline is a dangerous flammable liquid and completely unsafe.
Is it more unsafe to have a gas heater as well as a gas engine? Well, you already have a tank of fuel there, so.... I wouldn't think so.
The thing is it is pretty easy to find the heater itself, but they rarely come as a complete ready to install unit.... they tend to be missing the exhaust, the switch, the ducting, etc. (note to anyone parting out a bus with a eberspacher)

Here is the Eberspacher in our '56 Westy.
It was buildt before they started using the BN- numbers.
I believe this was a dealer install. It was there when the previous owner bought the bus in the early 70s. The heater says it is a 1957/58:

The BN numbers refer to Benzin (gasoline) and the number 2, 4, 6 is the heat input in Kcals. DA-6, as used in a diesel vanagon is a diesel auxilliairy heater with 6kcals input.
I don't know what number was used in different early buses, but BN-4 probably would have been stock
If you are looking to be original, that is. If you are just looking for camping heat, these are not the best choice. Probably Carver, Propex or Truma lp heaters are much better. Or the newer Espar heaters, DL-1C comes to mind.All these are expensive Like $600=$1100. But they are quiet and use very little electricity and fuel.

I don't speak french Major Woody... Very Happy
Catalan is a spanish dialect spoken in Catalonia, that is next to France... So pronunciation can be little similar...

Yesterday I calibred Pressure regulator - Valve Solenoid. This part should deliver 20-21cm3 of fuel in 2 minutes... So it's not difficult...

Also calibrated temp regulator switch but not finished...
Tonight I'll post pics.
