0.2gph X 10 hours = 2 gallons X $3.50 per gallon = $7.00 per night in fuel, plus maintenance X 100 cold days per year = $700 in fuel consumed

0.02gph X 10 hours = 0.2 gallons X $3.50 per gallon = $0.70 per night X 100 cold days per year = $70 in fuel consumed.

Ignorance is bliss, indeed. :lol:

 

Yup, you just proved it, wasn't talking about that. Now, where is that big "L" icon that I can post.

 

Heat a cab on less than a quart of fuel on a cold night????? I don't think so. Not enough BTUs to do the job. No matter what you use.

 

You can't say that stuff. That's like science, logic and common sense. That's just too much for people to handle!!! lol

I should mention also. I have a 12" 110v exhaust fan in my bunk running full blast and the driver window cracked open 2" all the time. I like fresh air blowing through the cab while I sleep. If I shut the fan off and close the window my heater can bake me out of the cab.

 

you've used the diesel fired bunk heater?

 

It's science. It's as simple as the definition of a calorie. Doesn't matter if it's an electric heater, gas heater, diesel heater or solar heater. A BTU IS THE SAME no matter what the heat source is and an area requires the SAME amount of BTU's to heat the same area to the same temp, period.

 

1 more vote for the Espar or Webasto bunk heater. I have a Espar and love it.

Spent a night in Gaylord MI last winter at 5 degrees had my Espar on low/med and without the curtain pulled in my sleeper I woke up sweating and my cab was 72 degrees.

I thought they used .08 gallon per hour even that is only .8 of a gallon in 10 hrs.

Steve A 12" exhaust fan going in the Winter? Man you must eat allot of roughage LOL

Oh ok I see,I admit I'm wrong and you are right.

 

The specs give a range, depending upon how high you have it set. At .08 gph, I would assume that is somewhere in the middle. Mine is usually barely on, which is why I use the .02 gph calculation. But even at 0.08, you're still using less than half of what Steve is, and you have more heat to show for it. Steve just doesn't believe that we are getting roasted out of our cabs. That's because he is an idiot.

Really all it shows is how inefficient APU's are, which are a hell of a lot more efficient than the truck engine.

Diesel bunk heaters are extremely efficient, since they are using a very small, high powered electric fan, and ceramic plates. My fuel line going to my bunk heater is 1/8". I can hear the mechanical pump click about three times a minute at best. My Webasto puts out 12,000 BTU on 0.02 - 0.11 gph. When the dial is set low, it uses 0.02 gph, and when it is set high, it uses 0.11 gph. The fan runs at a constant speed.
