Default Why would you heat a Nitrous bottle?

Realize I have no intention of using NAWS in my car, just curious why you would want to heat the bottle.

If a bottle gets too cold, it will reduce pressure in the bottle. If you heat it up, it will increase.

My guess is that if it gets too cold, you're getting less NOS, and if you give it just a little heat, it will keep the pressure constant. You don't want to keep the bottle "hot" though...too much pressure...

keeps the pressure high and constant to get the best N2O flow.

To answer my own question, I found this in a faq

A bottle that had 800 psi at 75 degrees would fall to 450 psi at 30 degrees, and only 275 psi at O degrees.
On the other side of the coin, heating the bottle increases the pressure, but heat also tends to make the N2O vaporize in the line between the solenoid valve and the discharge nozzle, which upsets metering and reduces N2O flow. Ideally, the bottle and lines should be kept at room temperature. At the drags, some cooling of the bottle may be required to achieve this while the car sits in the staging lanes, but a damp cloth or towel wrapped around the bottle will generally be all that's required. If you really want to pursue additional cooling, chill the line between the solenoidvalve and the nozzle, and keep that line as short as possible to reduce the likelihood of vaporization before the discharge nozzles.
