Suggest you turn the unit off. Remove the drain plug on the unit. The water drained should come out clean. If there is a lot of scale coming out with the water you may have to buy a cleaning wand that hooks to a garden hose and you insert it into the drain opening and wash out the scale and calcium deposits from the tank.
If there is a lot of scale and deposits in the unit, that might be the reason for its lengthy heating time. My 10 gallon unit will heat water in about 10 to 15 minutes on gas. Takes much longer on electricity. As you can see from the above posts, the heating time does vary a lot.
Your wh should, at minimum, be flushed at least once a year with a cleaning wand from camping world or camco. The ideal way to do this would be to put in 1 gal of generic white vinegar per 15 gals of water into the fresh water tank, run each cold/hot water outlet until you smell vinegar, allow the wh to fill. Let sit for 4-6 hrs then drain the fresh tank and wh. Then use the wand to flush the junk from the wh , then refill the system with fresh water. Performing proper maintenance on your rv will noticeably reduce problems later.
