Espar Heater Question

Hi everyone,
Can someone tell me where Sportsmobile mounts the Espar unit on the RB50 and/or EB50 model, please? Are they inside or outside? I want to know if they get mounted in different locations based on other equipment selected.

If anyone has photos that would be nice.

Thanks.

steve

Re: Espar Heater Question

Yes they are mounted in different spots depending on other equipment and available space. And there is part interior and part exterior to the van.

Re: Espar Heater Question

Are you talking about the Airtronic (Space Heater) or the Hydronic (Water Heater) unit. On my EB50 the Airtronic is all inside (expect the fuel pump). The heater is located just behind the drivers side rear wheel hump. Its a bugger to get to. There is one duct leading from the heater that comes out at the floor below the sink. The combustion air intake duct is routed up between the frame and the house battery, the exhaust duct is just behind the rear wheel well.

Sorry, too dark for pics.

Re: Espar Heater Question

If I were doing my build over, I would find a place where it would be easy to access for the routine maintenance even if it meant loosing valuable storage space. At the present location, I have to unload everything out of the forward closet and then try to work on it. Not fun at all.

Re: Espar Heater Question

Thanks guys. I am talking about the Airtronic. And since I know they need to be serviced I wanted to know the easiest place.

What about in the interior box above the rear passenger wheel well. I think those of you with showers may have the shower there.

So just to be clear the entire Airtronic unit is inside the van and only the fuelpump is outside (other than hoses)?

Re: Espar Heater Question

My shower is on the passenger side where there is an access panel under the bed. I wish my airtronic was there instead of below the closet. (the inverter might be a problem if heat is an issue)

Re: Espar Heater Question

Thanks Dave.

Anyone else have theirs in a different location or even mounted outside?

Re: Espar Heater Question

After I posted those photos of my Espar, I ended up taking the unit out (and in and out again a couple times...). On my RB50 the heater is next to the wheel well hump. To get it out the first time, I ended up cutting part of the lower side wall of the cabinet out. I kept the piece and reinstalled after getting the unit back in. Alan told me the heaters are installed after the cabinets are in but I can't see how. Of the four screws the hold the lower mounting plate to the floor only one screw head was accessible while it was in the cabinet. The body of the heater blocked access to the other screw heads. The installation location of these heaters was clearly not designed for regular service maintenance. After doing it a few times, I had it in and out without taking all day, but it is not easy. The hole in the floor under the heater has the intake air pipe, exhaust pipe, and fuel line in a tight space. The hole needs to be sealed as the unit is installed. I added some 3/8" closed cell foam under the mounting plate to help seal the hole. I took a bunch more photos but never got them posted after all the hassles with it. Gotta do that someday...

Re: Espar Heater Question

No. There are intake and exhaust hoses for combustion that are outside the van. I don't think it would be a good idea to have those inside.
