blue estate:
Until one Monday on an early start and Click as the battery is flat

I would have thought that a night heater uses more fuel than it does juice from the battery…
If there was a set-up where the battery was likely to go flat whilst the vehicle still had fuel - then the pump for the fuel line would cause the heater to fail how exactly?
The heaters I’ve come across over the years - fail because the fire-up doesn’t work - which you find out the moment you switch the thing on, and all you get is a stink of diesel fumes, but no actual heat.
I’d also be interested to find out how much fuel is used per hour by the different kinds of night heater…
Sidevalve:
Takes my night heater about ten minutes to get the cab reasonably warm on a frosty Monday morning; which is long enough to do your walk round check after you’ve put your card in and switched the heater on.
Don’t see the need to leave it on all weekend, that’s just sheer laziness.
I’d consider defecting it, if the night heater was not firing up, at this point, the current climate being what it’s like…
You wouldn’t want to get stuck out on a night out, only to find the night heater wasn’t working… Would ya?
…Especially if you’re doing something like a Minneapolis to Chicago run right now!

That’s just the point. By running it on a Monday morning you’re testing its ability to fire up from cold. I’ve made the mistake of taking night heaters for granted before, never again!
Eberspacher D4 used 0.11 litre/hr on low and 0.25 l/hr on medium outputs. Assuming it’s a modern well insulated cab, once up to temp it should only need to tick over really.
So on a Friday eve to Mon morn 60hr break maybe between 7 and 10 litres?
But I’m with Sidevalve: if you ain’t in it, it’s unnecessary.
Night heaters are good for panicing people esp if they havent been used for weeks. Get a nice lot of smoke out the backend and someone comes running asking if the truck is on fire (yes I’m evil)
As for the timer, can someone tell me how to set it in a DAF CF as it has a twist knob to set the temp (kindof) amd a switch on the dash for on / off.
Defo no timer although that could be the day driver being nice and leaving it on.
It won’t be running all weekend ,it cuts off at the set tempand comes on and off as required to keep it at the desired temp ,much like your boiler at home
I always thought that if you turn a night heater up to the max on the thermostat - you’ll damage it over time quicker than if you let it cut in and cut out because you’ve set it to a more reasonable temperature, such as 20-24c rather than “max” or “hi”. Actros heaters - get really roasty if you turn them up to the top, I’ve noticed…
Go on then anyone clever enough, if you drive an MAN tell us exactly how to set the heater timer,
Right, I’ll pick up that gauntlet. Yes it is a crap timer and when you think you’ve set it, it’s always a guess as to whether you have or not because there’s no indication it’s set. Stupid!
First step is to make sure the clock is correct.
Press P 5 times and see if the time and day are correct.
If not press the + button repeatedly until the day is right then press P then the same for the hours and minutes.
To set the timer press the P button which makes a little 1 flash top left.
Press + to choose which day you want it to come on.
Then press P again to make the hour flash. Press + to choose the hour. Repeat for the minutes.
When you’ve done the minutes press P again until the 1 is flashing again then turn ignition off and go home.
All being well you’ll have a nice toasty cab in the morning [emoji4]
Just to add, one of the 5 presses on way to clock settings is PH. This is how long you want the heater to run for. I leave mine on max which is 120.
No better sound at 4am than a night heater that’s been running for an hour or 2 when you get out your warm car and start walking towards the lorry.
