Diesel Heater Under Passenger Seat With Adblue.

[Stevie K]

Hi everyone,
I'm getting started on my build again in prep for the weather cheering up, and the next item on the agenda is a diesel heater. I've got one on the way from China and now I'm trying to figure out where to put it.
I have a T6 with Adblue, but the only place that really works for me venting out the heat due to the set up of my build, is the back of the base of the passenger seat (battery under drivers). The problem is, from what I've read the Adblue tank is directly under the passengers seat.
My question is: is there space above the Adblue tank/under the floor tray to fit the heater inside, and then route the pipework down through the floor and then over to the drivers side?
... or perhaps could I mount the heater outside, under the drivers seat and then route the heat pipe over and somehow between the tank and up throughout the floor under the passenger seat?
... or is my only option, mount it under the drivers seat, up through the floor under the drivers seat and then have the ugly pipe running across to the passenger seat above ground (I don't want this)?

Any advice appreciated... cheers!

They mount in a similar way to a branded heater, so couldn’t you mount outside under the driver’s seat, with the inlet by the front step and the outlet behind the driver’s seat? Like this?
These are the only bits visible from inside the van (apart from the controller).

This is on an EU6 T6.

You know what, that's not a bad idea. There is a spot where I could have it coming out of the floor behind the handbrake. Another thing I never thought of, do you need to have the inlet coming from inside the van the equalise the pressure? I'd just planned on having it suck air from outside.

The inlet from inside the van is recommended in the Webasto manual.

There is a real risk of sucking in exhaust fumes into the van if it was drawing air from outside . Would be extremely dangerous or even fatal! Don’t do it!

Also, it’d be working harder as it’d be heating cold air rather than air from the van that was pre heated.

Makes sense... cheers for that.
