Bottle heaters, the ideal gas law, and you. A commentary.

[The Shaolin]

So, right now, I've got this beat-up POS bottle heater. It's white, and it's two wires and it gets warm when I give it voltage. I've never had my bottle over 800-850-ish psi...I need a better bottle heater.

I was looking at the NOS brand one...the temperature regulated one.

It says that it monitors the temperature of the bottle to keep it at a constant 80 degrees.

Now, having taken a few chemistry classes in my day, I know, (as all of you should) that PV=nRT.

So, let's say that the bottle is full. X psi. Now it's at 80 degrees, and it's at optimal pressure.

Okay, now the bottle is almost empty. 80 degrees isn't enough, right?

Is it even worth going with a temp monitored one, or should I spring the extra $100 for the super sweet pressure monitored one?

Just get the pressure monitored one. Is the bottle heater you have now good? If so you can just get the kit and use your heater. I love being able to turn it on and not have to worry about it.

pressure monitor is the way to go

i need one, i got tired of turning it on and checking the pressure every 5 minutes just to make sure my bottle wasnt going to explode

800psi seems kinda low dude. I mean, itll work like normal, and I know thats where NOS says to have it, but try getting it up to 900 and see how it feels.

That's not a bad price...$170-ish...the NOS ones were in the neighborhood of $250.

my heater is...okay...it does work, but it really doesn't get that hot.

It gets warm to the touch, but that's about it. How hot should it get if I just turn it on and leave it?

Oh, I know it is. Sometimes it's 600psi or so. IWe've already identified this as a problem...working on the solution.

i have this bottle heater and it works great. stays between 900 and 1000 psi. i highly recommend it!

I would figure though you could just leave the heater on longer to get the PSI higher even though itll be better to just get a better pad.

I'd rather not drop $200+ on a heater...but it looks like that's going to be the way to go to not half-ass this shit.

I personally have the NOS temp regulated bottle heater.

The first thing I did upon installation was to bypass the temp sensor and run the heater straight on. Unlike a lot of people apparently, I have a nitrous pressure guage in my dash, so monitoring it is no problem. I like to keep mine around 1000psi. Through the course of an evening I may turn it on and off as needed and have never seen this as a bother.

To me it's common sense and is not a problem.

As for the exploding part, the nitrous bottle (much like a paintball bottle) has a burst disc setup for safety and will pop that before exploding your bottle. I am not saying I would want to be in the car when that happens though lol.

Well my Edelbrock heater gets pretty hot once its on for a while, I touched it once and didnt do it again.

I have mine set to get the pressure up to the middle of the green on my NX gauge which is like a little bit above 1000. I can tell a huge difference when I spray w/o the heater on (700-800psi) to with it on (1000+psi).

Yeah, my bottle heater is pretty damn hot to the touch.

and you can definately tell a difference in psi. It feels like nothing if I spray low psi. I did not have a heater the first couple of months but it was summer in Fl. so it was not bad, then fall came and I realized how important it was to have one lol.

[slowion2]

the green on the NX gauge should be 900-1100psi, yellow is 800-900psi, and red is anything above 1100psi. I have mine setup like Fury but my gauge is behind me on the bottle, though I can see it from the driver's seat. this will be changing soon though...

[phat95nosdsc2]

i liked spraying around 1100 it always felt better than 800....warm that sucker up!

[slowion2]

oh shit yeah, it feels like night and day

back when Tom in AZ used to post back and forth to me about how important it was I thought he was nuts, till I found out myself

+1, I thought it could not be that important either until I hit it a 1100 and realized what a difference.
