Went tankless to free up a closet, didn't want the risk of a tank of water leaking while vacant(unit below us), and endless showers when 6+ people want to get ready to go out after pool/ocean.

Regulation of temp is not the issue but only at a certain temp it becomes a PITA. Hot water requires a certain GPM float rate to turn the ignitor on to produce hot water from the tank. During extreme hot evenings, there are times a cool shower is necessary but not cold water. If that GPM isn't met, then the heater will not go on to produce hot water. cold water is all you will get and you have to turn your faucet to hot and wait if the heater is a long ways away. Stand away from the cold stream coming out of the shower to prevent shrinkage is no fun. Setting temp is a whole different thing. Temp. balancer at the faucet usually isn't a problem.
