BTW, does your screen name EL34 have anything to do with the audio tubes?

Yes, my business is Tube amp building supplies for vacuum tube guitar amplifiers
I used the name EL34 in games going back to mid 90's
Quake 3 was probably the first time I used it

So I have been using it ever since on forums Smile

Howard Dumble comes to mind Santa Cruz not far from me. Do you do mods?
Sorry that was off topic.

Cool...I have a few EL34 and EL84 stereo amps, is the reason I asked...

I even have a review of a little tube amp published over on Tube Depot. 

Well small world.

Ok, back to pipe heaters and heat pipes....

Back when I first got my RV and heated with the stove on low, I found that turning the burners down really low, sometimes the flame went OUT. Now you have raw propane being emitted.

I'll stick to using heaters for heat and stoves for cooking.

I thought I would do another test this morning of the stove heater
BTW, my van is in my driveway, I don't live in the van Smile

I meant to get out early when it was 13 degrees F but I forgot

It was 23 degrees F when I entered the van and 23 F is the high of the day

I set the stove flame on low and the 12 volt stove fan on high so it would blow the heat away to the side faster

One hour later is was 44 degrees F in the van

Pretty good considering the entire interior shell keeps radiating cold and it's way harder to bring up the temp from a very low temp like that

It way easier to maintain a temp or bring the temp back up a bit if the interior has already been warmed up previously

Anywho, just throwing out info here if case anyone wants to try this, modify it and take it a bit farther

May I suggest, if you have a similar day, to run the test over without the computer parts, just the fan blowing on the pan. I am curious if there would be any difference since the flame is a constant and the only source of heat.

Yes, we need to plan a man in a van with a fan blowing on a pan.

I don't think I am not going out to the van today, it's 5 degrees F right now  Undecided


Also, I don't want to take my rig apart
It has thermal paste between the pan and the aluminum block on the heat pipe which gets messy and I don't have any more of it on hand

I probably have several old mother boards and computer cases with 12 volt fans
Most like a bunch of people here do also


If someone else wanted to try that....
You would have to set the fan off to the side away from the heat because they are plastic
And you would have to raise it up and aim it at the pan so you did not blow out the burner flame
And somehow hold it in that position so it did not vibrate around and move
