Mornin y’all …
As winter arrives, I have gotten to pondering about the workings of that wonderful contraption known as the night heater …
All I know on my Scania the ambient cab air is pulled out of the little vent behind the passenger seat, and then warm air magically appears from the vent behind the drivers seat, but what happens inbetween??
Anybody good at explaining such things to a thicko like me?? 
It burns desiel there’s no magic to it
Good chance nothing will happen if you have not given it a whirl a few times over the summer months.
Same as your central heating at home,don`t leave servicing until its to late when engineers are at their busiest and you have to wait for a slot in the cold
go on the link and scroll down a bit.

Might as well be with my night heater 
as it’s up the spout
Our lot brought a couple of Rigid MAN’s in the summer, both with sleepers, one of them found out a couple of weeks ago that it hasn’t even got a night heater [emoji951]lol, apparently, the rumour is-it’s gonna cost around £5,000 to instal one [emoji15]

I’ll ask the guy at our work who has a sleep one, if he has a night heater.
Although currently he doesn’t have a truck, as an agency driver turned the back into a parallelogram last week!

Like this 
Little diesel pump shoves fuel into a chamber.In the chamber is a red hot plug so the diesel burns(combustion chamber) Outside this chamber is another chamber that has air blown through it.(heat exchanger) The warm air from the outer chamber is blown into the cab the inner chamber exhaust gasses are vented through an exhaust under the cab.

I still think this explanation is correct
I want one like Nick’s
Word of advice, never kill the power to the truck with a night heater running, you’ll melt the plastic.
I used to like the Webasto type, heated the water in the cooling system so a warm engine to start and a cosy cab.It was not noisy either, unlike the Eberspacher types.
