One of the upgrades we have in our RV is a tankless hot water heater, the Truma AquaGo Comfort. It supplies hot water reliably for showering, rinsing, and hand washing in recreational vehicles. The system tells you when it is time to decalcify with a series of flashing lights on the control, so we knew it was time.
The process
Truma has a video on the decalcification process:

Whenever we decalcify, we always order the next set of tablets, so we’re ready when the control panel tells us it is time. But before we use the tablets, we’ve got work to do. Truma includes small door hanger signs to put on faucets, so no one tries to use the water during the decalcification process, so we hung those up. Then we went outside.
Once the door is closed, it takes 3 hours to fully decalcify the system. We cannot use the water during this time, so we left the RV and ran errands. There are some steps after the 3 hours are over, but it’s mostly running the water until 8 gallons have passed through.
