Ducting for diesel heater


With my fiture van build Im planning to install a 2kw diesel heater, a cheapy as the van build will set us back a lot

Ot appears the chinese copies only have one hot air outlet for heat into the van. Is there a ducting unit for these?

Thanks

You just need  T piece or a Y piece and you can run two ducts

No worries df

The front duct not far from the heater allocation. The rear duct 4 metres to the ensuite. Might restrict the fron one a little to get the ensuite one working well.
Thanks

I had a diesel heater in my 21 foot van and found that 1 outlet was more than enough. I would not worry about the second. You will love it when you get it working- cheap to run and warm. Enjoy.

on my previous heater/van, there were two 1mtr ducts supplied, but my new cheapie there was no ducting for the air intake, so I put in a small grill to allow air to be sucked into the area under the seat where the heater was. It works a treat.

 Thanks treecrest, that means the air intake is from inside the van. That would make heating more efficent but it wouldnt introduce fresh air. I assume the way you installed it is the norm.

Yeh, doesnt seem that hard. Regards

The air to be heated, is circulated within the RV. The further apart the inlet and outlet are from each other, the better the RV is heated. For your information, you can get tight 90' bends that clip to the outlets of the heater, for those awkward installations. I have mounted the heater outside the van, as there was no suitable spot inside, works fine. The fuel tank is mounted in the boot, out of sight, but it is on runners, so I can pull the tank outside when filling so there's no spillage inside. I also have vented the tank outside the van so there is no smell.

The hot air ducting can get very hot, I have insulated this ducting so there is no heat loss.

In our case the heater is in middle of sofa seat . Inlet is behind drivers set . Outlet is opposite. About 1m hose each side . Keeps noise levels down . May fit another T on inlet as we store things between drivers seat and sofa. Often restricting ? So another inlet to the side would help .. I assume the fan pushes air better than sucking. Thereâs vents through roof etc for fresh air . Open window if required . Heat setting is too high in most cases if stuffy anyway .

 The short answer is - they all only have one hot air outlet. The standard basic kits for all of them is just one hose. You have to purchase the splitter separately if they do not offer a two or three outlet option.

I have always been able to locate the inlet vent/s near the doorway - that way fresh air, thru the bottom grill of the door, will enter the van if required.

Hi Glen. My only concern with that is LPG leakage say from the stove connection. LPG goes to the floor then uses the vents in the door to escape...eg the reason for the door vents. If the intake is there wont it get sucked in there and LPG be circulated around the van?
