    Would a Webasto 5KW water heater KEEP a truck warm sitting overnight in the teens? This would be using the heater to maintain heat in the engine/ heater core not so much heating from ambient. Would running one all night kill the batteries?

    I think it will heat the engine to 160 ... that unit uses a fair amount of fuel and yes, overnight it would drain the batteries.

    I have used Webasto water heaters since 1989 and have found that the old (dw?)2010 was a combo unit plumbed through the bunk heater and a 4 battery set would last 8 hours at 0 degrees F and still start the truck, 9 hours and no start.
    The TSL 17 that I have used did not heat the bunk, it was plumbed direct to the engine only and had a 2 hour timer that was more than enough to start a 3406 Cat,12.7 Detroit and a 13L Volvo at 25 degrees F below even after a long weekend.
    I have not used the TSL 17 without the timer and would not recommend it.

    The heater I am referring to is a thermo top c 5.2KW
    https://www.webasto.com/fileadmin/w...eet/usa-heavy-duty-datasheet-thermo-top-c.pdf

    The idea is to let the engine coolant heat the cab while the engine is running and upon shut down for the night use the thermo top to keep the coolant at 140~150 F overnight? That would not be a continuous use perhaps? With a winter front on the grill keeping the heat loss down, maybe run the heater for an hour or two then cycle an hour off repeat overnight?

    I don't plan to be in low teens, mostly low 20's high teens 15+ I stay on the southern routes but it does get cold in New Mexico and northern Arizona

    This is one idea, the air heater is another however I would like an engine heater as well. My c13 is kinda cold blooded anyway. Battery life seems to be the key issue. I wonder if adding some lithium batteries for the heater would work? They don't like cold either, they could go under the bunk?

    Just get the combo heater every one uses. Small one on frame rail that only heats engine on time set for 1 hour before you get up.

    Then have a airtop 2000 for the bunk.

    No battery issues and everyone including your engine is warm and happy.

    The problem with your idea is you have to run the truck heater fans to get heat and they will suck your batterys down fast. Just not very efficient. And why do you need your engine at 160 all night? 1 hour before you get up is plenty on a modern electronic diesel.

    There are switches that cut the power if the voltage dropps beneath a certain set voltage.
    Allways leaves you with enough juice to start.

    I agree that the air and water heaters are the "right way" to go. I was searching for a single point solution for occasional use.

    The generator and space heater are looking better, I did see the other post about space heater in trucks by the way.
