We have 3 valve system and no check valve.
No back flow, no lack of hot water due to stuck/failed check valve.
T-stats will shut off electric/gas heat when tank temp reaches set point.....so even without water the tank will not be damaged. Electric element may burn out due to lack of water but tank will be OK (Damage could occur if tank was HOT and cold water was put into the HOT tank)
