How long does the potable water system take to warm up on the CRJ 200?

Explanation:
Hot water for the galley is produced by a potable water heater, and it needs time to bring the stored water up to a usable temperature and build pressure. On the CRJ 200, the documented warm-up time is about 15 minutes after power is applied. This window accounts for the heater’s heating rate, the reservoir size, and the electrical power available. Five minutes isn’t enough for the water to reach a safe hot temperature, while 30 or 45 minutes would unnecessarily delay service and isn’t the standard operation. If you want hot water sooner, start the heater as soon as electrical power is available and plan for roughly a 15-minute wait.
