Nitrous bottle heating time?

[atrainsgt]

Got a question for those of you running nitrous and using a nitrous bottle heater. How long does it take for your bottle heater to get the pressure from about 800psi to 1000psi? My NX fire/ice bottle heater/cooler takes over an hour to do that. Seems like a long time.

until the gauge says so.
