You have to run the engine for that though.

from reading its about 1 to 2 litres per hour could be more all depends if it on high or low
theres charcoal heaters and rocket stove heaters
ive got a brick built shed so i can use a rocket stove system 11 x 9 and its too warm with what i have in there

Having it inside would be more efficient I would imagine. Also the exhaust could take a longer route to outside the wall. For safety, and peace of mind, a carbon monoxide meter fitted near the exhaust would be wise, I think. Looking at the details, the heater is a lot smaller than I thought, and that was the main reason for it living outside.

I dont think its as much as that, the specs on mine say 0.12-0.24 liters per hour,only used around 5 liters all december.

100% calorific value of 1 Litre 35 Second viscosity Heating oil (Gas Oil) = 10.85 kw/hrs so 5KW heater is going to use 0.5 ltr ish for 1 hr at 100 % so with loss of exhaust heat 0.64 is looking about right (poss if not a little low ) so road fuel you are looking 70-80 p hr on full, obviously with kero a LOT less cost, now with a large motor home I would guess it would be on 80/90 % of the time in cold weather, due to heat loss through large body, also as an average normal front car heater produces 7-10 KW's and doesnt usually have enough heat for the rear too, hence most large vehicles have front and rear heaters run off the engine coolant, albeit single glazed and that normally is travelling so heat is usually lost due to movement, imo.

yes had that issue with the one I fitted, the pump used its std bracket and was noisy I wrapped it in foam IIRC and the exhaust was little noisy too, in middle of the night, a little silencer sorts that £70 ish

If you read his requirements
You will see why.

I need to have the best of both worlds, I want to run it whilst driving but also when parked

Hi just a quick comment..
they draw quite a few amps on start-up (all makes) and if your vehicle or boat has a slightly low battery, or thewires to the heater have any dry joints or corroded battery, fuse, switch or breaker connections, then the heater won't flash, may also develop a fault code inits ECU, "return to authorised service agent" and all that palaver.
You need good thick wiring to them, clean fuel, and make sure the exhaust isn't blowing back into the van..
Edited to add, they do use leccy, and are perfectly capable of flattening your battery overnight!

Weirdly , if i add a fuel filter it has an error code and doesnt fire, take the filter out and it works fine
I've been looking at the chinese ones on ebay for my workshop and I'm not sure if I would trust one as they are so cheap, that led me onto a 2nd hand eberspacher but I don't know much about them. Does it matter what make of vehicle they come from? Is it just a case of buying the heater and controller, feeding it 24v (or 12v) connecting the pump to a diesel tank, sort the combustion air inlet and exhaust and away you go?
Is it possible to replace the controller if its missing with a simple circuit? I'm not bothered about thermostat control or controlling the heat output, a simple off or on at max output is ok.
Finally whats the options on fuel? Looking at Norms post using road diesel puts it at a similar price to electric heating so its pointless using it my workshop as I already have a couple of fan heaters.. However if I could use something else it would work out cheaper? I've never tried to buy red diesel so have no idea on price or how easy it to get 5 or 10 liters at a time.

1.5mm2 is fine unless you have a stupidly long run of cable, as for dry joints/corroded connections etc well no electronics likes poor connections.
As for flattening your battery, well you really should have a twin battery setup if your running anything off a battery with the engine not running, unless you like bump starting your vehicle
I never fit a fuel filter to a diesel powered heater, just a dip tube that finishes an inch or two above the bottom of the tank so you can't drain your tank by running your heater, ideally you should stop muck getting in your tank in the first place rather than filtering it as it comes out. The pump isn't very powerful but that's deliberate to try and minimise the electric requirements.Weirdly , if i add a fuel filter it has an error code and doesnt fire, take the filter out and it works fine
I Have 6 of the Eberspachers, I love them, one D2 in the VW T5, one D2 heating the workshop/shed, soon to be replaced with a spare D4 as I need the shed D2 for a new Van project.
One D4 plus that's a back up heating system for the house, and a couple of older D1LC compacts as backups.
The D4 plus puts out a huge amount of heat and can heat up a large space really quick. (noisier + uses a lot more fuel, it moves a lot more air then any of the other models)
Run all but the one in the T5 on 28 heating oil 35p Lt in the summer.
They run better and hotter with less carbon build up issues on Heating oil/ kerosene.
Once set up they usually problem free, just need to change the glow plug atomiser screen every 400 hours or so, (£1 each posted from china) £8-9 from the UK.
To the OP stick with the tried and tested Eberspacher/Webasto as they are known safe/ reliable!.
One thing with the Eber's always use the Eberspacher correct pump, lots of Chinese copies about and the rarely deliver the correct amount of fuel this can lead to issues with starting/ low heat output and smoke.
Simple and efficient +very cheap to run.

Thanks I knew we had to have a collector amongst us
I have been offered a 24v one cheap could I just use a small step up tranny?
Im using one on mine.
I did read somewhere when i was looking that there fine on webasto's but Eberspacher don't work on them, dont know if that's true.
