Worst case, it is on only the entire time the timer is set for on a daily cycle.

Yes, those timers are useful, but with my 1.8kw coolant heater, if my pump fails the heater element is likely to be toast within minutes, and if the thermostat fails it is likely to be toast within a couple of hours. The company who makes these heaters sell far more 3kw units than 2kw units but I wanted a bit of a margin for error!
I'm not complaining, and I like that my more powerful heater can make a useful 40 degree C temp rise in 20 minutes, but keeping the power of these heaters below the level where thermostats and pumps are necessary is quite smart from the KISS and reliability point of view.
