Ran our Chinese one at Jericho for about seven hours, didnt play with any settings. Filled it up next morning, 0.65 litre.

Are you concerned that you are burning more (or less) fuel than expected?

The specs on my Eberspaecher states 0.1 l/hr = 1l for 10 hrs continuous running on low up to 0.3l/hr on full noise = 3l/10 hrs

I turn mine on to 20 degrees initially for a few hrs and then run it overnight on 15 degrees in cold weather ie 3 degree o/nite temps.

My fuel consumption ranges from 1.5l to 2.5l per 10 hrs

Either way, they are very efficient, keep warm for less than $5 a day.

It is all dependant of the outside temps as to how much fuel you burn

 I use a 20l container so I dont have to fill so often.

In cold conditions, you wear more cloths so the temperature can be lower and still maintain comfort.

When its cold outside, I wear appropriate clothing but I dont like wearing heavy clothing inside

After 20 years without a experiencing a winter, I had to buy blankets, a doona, long pants and shirts when I left Darwin . I even had to but shoes because crocs dont keep you warm

I removed the doona asap once I travelled north a bit.

Luckily, we are all different and like different things. I had friends in Darwin who used to crank the a/c right down to 17 and sleep under a doona.

Mine was a constant 27 all year long

We also have a eberspecher diesel heater in our van and I have found it uses around 120ml per hour. 

But my guess is that if the ambiant was very low say 2dg C then it could use more.

However we turn it off when going to bed and the first awake in the morning turns it on. This system works for us.

I think that the Question of the original post has been well answered.

We for one, in regards to fuel take the view that no matter the price, unless you fill up you are going nowhere, and similar with the diesel heater.

Anyway, the warmth we enjoy from the diesel heater outweighs and fuel cost.

Very pleased we installed a diesel heater for the winter.

Our van has a 11 year old roof Air conditioner, Sound like a jumbo jet when in operation.

And as you know, on this forum, I have been asking when someone is going to invent a similar diesel cold air unit.

One can only hope it will happens.

was away for the weekend and used my Chinese jobby 3kw for probably close to 12 hours or more a day. temps at night were a guesstimated 5 degrees.
I definitely noticed I needed to turn it up due to it sourcing the cold air from outside to run over the heating element.
I might change that to cycle from inside the warm van to make it more efficient.
I went through about 5 liters of fuel for that , set at a low to medium heat. I set it manually not using the temp, but the van was around 18-20.
I would say that 5 liters got me around 40 odd hours or so as a rough estimate over a 4 day 3 night weekend. I also ran it for a while at full tilt to do a burn off.

It was sooo nice to be at a free camp and have a warm van to go into.
I even left big fire to head in for the night and don't often do that.
