How does shorter time help?
Any water heater looses some heat . The idea is to shut it off at times whan tou are very unlikely to need / use HW .

For instance , turn it off at nite , after your regular bed time . Turn it off early enough , before you regularly get up , to allow it to bring the water up to temp , so you can have HW for your shower .

The schedule can be made more complicated than that .

God bless
