I fitted ours underneath the van, that way I did not have to worry about where to put the furnace intake or exhaust. I placed it in a box that can be purchased from the supplier for that purpose. The unit can be rotated 90degrees so the intake and exhaust are exiting from the side, this makes the whole unit and pipework ery neat and out of the way.

The only hole in the floor is the hot air inlet which I have led to two outlets. I also take the hot air from the interior and feed that back into the unit, this way I there is no risk the heater is breathing in the exhaust fumes and it is just recycling hot air.

Never had any complaints with neighbours, used it two weeks ago and our friendly neighbour said he heard it start up and asked us about it as he wants to fit one also.

Hi Iana, I installed mine under the seat.( mainly for the wiring loom protection and out of the weather) the exhaust out the back r/h side facing back, you can run them while driving so nice and warm when you stop. the only smell is for about 10 seconds when firing up otherwise no smell at all. I wouldn't run to annex side, if annex all zipped up your filling it with fumes ????. the main thing is to rubber mount everything you can (fuel pump, fuel lines and even leads) and put the electric fuel pump as far as way from where your sleeping or relaxing as the tick tick noise when everything is quite seems to amplify????

And you can draw air from outside, whether you install the unit in the van or not, drawing air from outside sort of pressurizes the van with warm air which is great, the down side is if you have been on a dusty road then you have dust blown into van. Each to their own.

 

Sorry all, I said van and meant caravan. That's a great picture Landfall, and I will shortly crawl under our "Caravan" to see how the unit may fit. My main concern is how to bring the air to be heated, and the hot air tubes up and into the Caravan.
I don't have a lounge, the bed is in the center, ensuite at rear. two water tanks and a grey water tank.
This is not an easy journey.

This was the main reason apart from the noise factor that I was concerned about.

We have had one fitted into our yacht for about 7 years now and they are terrific, but can be noisy.

The exhaust gets very hot, also be aware that the pumps ticking can be loud as well, this needs to be sound proofed if possible.

If I can be of any further help, just give us a yell.

Cheers

We installed a diesel heater, last year. Now I have to wear hearing aids, but not at night or when the heater is on. So I hear nothing, on the other hand, Dee has good hearing and says we have no noise re our heater.

Soooo I guess that I must have done a good job in installing same.

The heater was a blessing last winter and we will be hopefully enjoy warm and snug conditions again this winter as we travel the outback of Victoria New South Wales and Queensland.

 Could be the placebo effect the heater is not working, but you feel warmer save a bundle on fuel.

Nothing beats a nice warm van on a cold winter morning.

I mounted our Eberspacher diesel heater directly on the floor and yes you have to pay attention to sealing the floor penetrations well but you would anyway to prevent the ingress of water and dust as well as the exhaust gas. It was mounted under the sink area, from memory between the mudguard and the cupboard door, if you get what I mean. It was a tight fit worked well with a very short warm air duct.

However don't put the exhaust out under the awning and don't put it out under one of your windows.

I used a flexible exhaust pipe with a muffler and directed it to the left side of the caravan and dropped the end of the pipe down facing the ground so the exhaust hits the ground and dissipates well.

Don't forget you will always be there when you run the heater but you may not always have neighbors and as Stl says there is a slight burnt kero smell that is gone in 10 seconds or less. Even if you take it out the back you still may have rear neighbors.

We never had a complaint or comment about our heater starting or running.

I also fitted ours with an inlet silencer and ALL items were mounted on rubber with the fuel lines mounted in rubber saddles. Make Clarke rubber your friend.

The result was an absolute silent heater and comfortable caravan.

Don't despair the planning and prep time, I was asked several times how long it took to install and when my reply was 2 weeks people would look at me as though I had two heads but you only get one shot at doing it properly-it's the old story, measure twice cut once.

Good Luck.  

 There was never enough heat given off the heater body to cause me any concern, even mounted on the vinyl floor and the cupboard door closed at all times.

Hi Iana,
A very definate no!
I think you should definately not fit the heat as you show in the photo. You need to ensure the exhaust pipe, diesel pipe and air intake are outside the van.
The installation manual shows how the furness must be fitted. You should follow this instruction.
Usual fitting of cutting one large hole in the floor with all the pipes outside the van. With your proposal all pipes will be inside the van where they entre the furness the result would be a high risk of fire and I would expect any resulting insurance claim being rejected.
If the chassis is in the way you need to find another location.
If you are in any doubt about how to install then get it professionally fitted it could prevent a disaster.

Yes I have a similar downward opening door under the stove, but nowhere to bring out the hot air inlet and heated air ports, also this area is also housing my emergency brake controller, not much room as you say very tight.

Thanks but this job is giving me plenty of grief.

This is what I want to hear. Thanks.

There is a genuine mounting plate for this type of installation,the plate can be viewed on the www.dieselheat.com.au site. Click on the caravan on the hhome page, then click on Belief 2kw heater, follow this down the left hand side and you will come to mounting plate heavy duty.  This makes the through floor fitting very easy.

 Yes a plate very similar to that is what the supplier was suggesting. It would have to be made so the flange was higher, again something to consider.

Thanks for the input.

Hi again,

This was the area I had many sleepless nights over.

I have our fuel tank under one of the seats inside the van, thus it is considerable HIGHER than the furnace. After drilling the appropriate exit hole in the floor I then went out along the bottom of the chassis rail, bolting the fuel pump at the upper level of the rail, this gave me he slight incline needed. It does not have to a continuous rise, only at the entry to the pump. My fuel line is three metres long. 

For the initial purge I attached a brake bleed vacuum pump to the fuel line at the fuel pump connection and sucked the fuel through, hooked it up and pressed start. Fired up first time with no code errors.

Just an update on the project. I have mounted the diesel tank on double acting ball bearing draw runners, and attached the assembly inside the front boot of the caravan. Now by opening the side door of the boot, I can pull the tank out so any spillage when filling does not spill in the boot. I have fitted a vent that will be plumbed to outside the van, so hopefully there will be no diesel fumes coming into the van.
Fitting the two sharply angled bends, will enable me to fit the heater body under the floor. Still doing planning at this stage, I am looking at mounting the heater so that the exhaust and combustion air inlet are vertically down, I'm doing this so that any water can drain out, if the occasion arises where water may reach the unit. Mounting the heater on its side would mean water remains in the combustion chamber of the unit. I have plenty of height to work with.
I am a bit concerned about the heat of the air that will be going through the floor from the hot air outlet of the heater. Planning on cutting a 100mm hole in the floor and packing it with fire proof rope as used in slow combustion heaters, clamping it with aluminium plates each side of the floor, ho can begin.pping this will cut back the heat going into the floor, and at the same time keep ants out.
The final part of the design is now the enclosure to protect the heater unit from dust, mud and water. When this is all worked out the hole making

Some have asked where I got the mesh.

A couple of notes, when starting at 100% setting, the unit, and the heat outlet hose gets pretty dammed hot, I am going to have to insulate the "Hot air outlet" hose, as too much heat is being lost inside the cupboard, I would not want that under the bed amongst storage stuff. The exhaust pipe gets really hot, and indicates to me that using the heater at a setting over 50%, would be a waste of energy, as the heater is just passing the heat outside.
Some noise from the pump, so I am going to have to wrap some sound proofing over it. The combustion inlet also had noise, and am planning on a air filter to clean the air and silence the intake.
At 50% or less the heater performed well.

Hi guys, Have just purchased a 2.2kw Tuit from Ballarat guys.
Now while i wait for the delivery i have a couple of question ( probably more to come )
Firstly i propose installing the unit in the cupboard under the dining seat.
Now i am thinking about making a timber box to enclose the unit,should i insulate the box ?
Next i am mounting the fuel tank on the rear bumper and thinking about putting the filter and pump close to the tank.Is that a issue with distance to push the fuel ?
I am thinking of blowing the hot air under the table and sucking from the end of the bed.What have others done.
Thanks
Brian
