Bunk Heater Question

Hey all,

So I'm currently in training and spending the weekend at a pilot in NY while my trainer takes his home time. He left me the truck (2015 cascadia sweet! not like i can go anywhere though haha) And its getting pretty cold here tonight. How long can I keep the bunk heater running before the batteries get drained? I'm thinking its hardwired and not run through a low voltage detector so I wanted some input before I killed the truck haha

Travis, don't worry about it. You can run that thing for a couple of days and be just fine.

Awesome, I was hoping that would be the answer. Thanks Old School!

Just don't underestimate that heater. That thing can get the interior so hot you'll wake up from your deep sleep and sprint out of that truck. But like OS said, don't worry about draining the batteries. It runs off diesel.

You got an APU on bored? If so that'll kick on too and recharge batts...

I can go all night with my bunk heater on and it won't even kick my APU on. If I turn the fan on, it'll kick on in the middle of the night. But the heater its self won't.

Generally most are hardwired in if I'm not mistaken.

Like Daniel said, that little heater will heat up cab pretty quick. Especially if you have the back closed off. I had to get a window cover just so I could keep my bunk area open more.

APU:

Auxiliary Power Unit

On tractor trailers, and APU is a small diesel engine that powers a heat and air conditioning unit while charging the truck's main batteries at the same time. This allows the driver to remain comfortable in the cab and have access to electric power without running the main truck engine.

Having an APU helps save money in fuel costs and saves wear and tear on the main engine, though they tend to be expensive to install and maintain. Therefore only a very small percentage of the trucks on the road today come equipped with an APU.

I remember one time I woke up at 0300 super cold. Half-asleep, I turned on my bunk heater. Was too sleepy to realize I put it on full blast.

20 minutes later I wake up and my interior thermostat reads 107 degrees. I almost died!

No, unfortunately no APU on board, but after having this bunk heater on for just a few minutes it's nice and toasty in here. Glad I only put it on 75 instead of full blastin it haha

Yep that bout sums it up... My heater fan is controlled by temp so I can set my temp to 65 and have basicly a low fan, or goto 75+ and get superbfan speed..

I can also turn my ac fan on and cool it down a little if its to hot.. Kind of cool in a way. (No pun intended) but I do enjoy having control over temp instead of just one setting. I keep it at 68 and don't wake as much as I did with it at 70.. I'm sure once winter fully hits It'll go up.
