Diesel Night-heater hot air outlet

[DaveyB]

I plumbed mine in using the OEM parts to put the inlet through the drivers step and the outlet through the b-post because all my leisure electric circuits are under drivers seat.

@DaveyB drilling a hole on the drivers step isn't a problem for the inlet. However, the pip work for the proprex doesn't fit up the B Piller. I cant afford to purchase all those VW parts. I just need a safe point to drill a simple 70mm hole.

I have the extreme battery supplied by travelvolts mounted front to back. A ctek charger and small fuse box with the heater duct under the drivers seat. There is plenty of room to fit all that under there.

Hello. I’m trying to figure out this exact setup under my drivers seat. Do you have a pic of your layout including the heater duct and do you know what battery it is you’ve got under there, or just the dimensions if possible please?
Thanks
David

Hi David
Sorry that is the only picture i have , it is the extreme battery supplied by @travelvolts , as part of his leisure battery kit, with a planar diesel heater.

Thanks

I put my diesel heater underbody drivers side and put inlet through drivers step as per usual and put warm air outlet exiting under passenger seat as I have a camper conversion with ķitchen down drivers side.
I brought duct across just above exhaust pipe.Had to drill 70 mm holes through heatshield and plastic underbody trays.
I put extra lagging on exhaust pipe where duct passes close and put insulation on duct to limit heat loss.Works great.
Warm wife, happy life.

Hi there. This is what i am trying to achieve but was unsure. Is this picture looking from the front of the van? Is there a specific place i need to drill my 64mm hole under the passenger seat base or just anywhere. Also did you have to remove the plastic from below the van as i heard that was a big job. I currently have my drivers side plastic off and hope to fit my heater tonight under that side & have someone else complete the fuel line on a ramp for me. Does the exhaust wrap just protect the duct from the heat and is that foam you have on just for rattles. Sorry for all the questions

 

[AussieMick]

Hi, I removed all the plastic under trays and it wasn't that hard. I wrapped the exhaust pipe where the duct crosses it just in case it got too hot for the duct, I wasn't sure but I was being careful.
I put heatproof sleeving on the duct to minimize heat loss under the van.
When I removed the passenger seat I drilled the hole where it cleared the wiring and it was clear on top and underneath from ribs etc.
It was a flat bit and I drilled a pilot hole to check first.
Keep your duct as straight as possible or you will obstruct airflow. I used a right angle piece from the heater outlet as this pointed the duct across to the passenger side without a huge loop.
Ask as many questions as you like because I should be able to answer them hopefully.

great thanks for your help. I haven’t any 90 degree bends so hopefully I’ll be ok. I presume you used the 70mm just do you had a bit more room to play with?
Hopefully I can find something to wrap the exhaust and duct with.
I’ve went through 2 cutters trying to cut my step hole in and didn’t know I had to cut it slow

 

[AussieMick]

google is your friend, if your unsure about something often looking it up can save a bit of pain.
I got my exhaust wrap from an auto shop and duct insulation online but from Australia so not much good for you, Yes I used 70mm for penetration holes to give a bit of clearance.

Hi all,

Started the journey to investigate a diesel heater plus installation and decided on a Eberspatcher model.

I'm wondering on peoples experience and recommendations with the product and the possible locations of the vent. Most research I see positions a vent either in the drivers foot-well or under the drivers seat. I have two captain seats and know the drivers includes the leisure battery plus solar controller, something completed by the converter so not sure of the available space. Assuming the heater is installed underneath, what options exist for the vent?

Also, any recommendations on installers in the South West area? Happy to travel for the best installation.

All advice welcome

Thanks,
Matt

I personally would fit an out let near the drivers step as you say and one just behind the drivers seat, yes that’s where mine are but it works well give plenty of room for locating the exhaust underneath and air intake, I have left the space under the drivers seat free for other storage hence why the oilers are where they are

 

[Niknak]

Make sure being picky if your under slung mounting you see that who ever fits it primes and paints the holes in the body work, it’s becoming my pet hate at the moment

Hi all, I've had a autoterm planar heater fitted but the company have fitted both the heater out put and air intake next to each other under drivers seat, as opposed to intake coming from the drivers step. Can anyone forsee any issues with this?

 

[oldiebut goodie]

Yes! Stupid idea.
Extract from Webasto manual:



Remove the hose from the inlet and allow the air to enter from under the seat alone is the easiest solution. Change the vents for directional ball vents could be done also to stop the direct flow from out to in. Amateur installation with no thought as to air flow, some people should not be allowed to install heaters.

Thanks...my fears confirmed!

When the inlet is taken from drivers step, does it exit the van body there and underneath or does it work its way back under the seat then exit the floor pan? My concern is I now have 2 holes under my seat.

 

[oldiebut goodie]

The inlet in the step is only used when you have a heater OEM mounted underneath the van as it is close to the inlet on the heater.
Is your heater internally or externally mounted?

Thanks, it's externally mounted. So in theory shouldn't be too hard to change over the inlet ?

The two holes under your seat look to only be in a piece of aftermarket trim panel which could easily be remade with only the outlet hole. If as @oldiebut goodie says the inlet is taken from under the seat base no additional hole is necessary. However do make sure that a grill is fitted on that inlet to prevent items entering the heater and fouling the fan.

 

[oldiebut goodie]

What I would do is just have the inlet under the seat - there is plenty of air flow under a seat for that. Just terminate the duct with a grill somewhere where it isn't likely to be blocked with anything loose like cloth or papers etc.
You could then convert the inlet on the panel to another outlet with a Y-connector to save having to replace the panel. With directional vents it can then direct heat to both sides of the van.
