As for the heat expenditure, now that's debatable and it depends on how much time heater stays on vs. off in the "on 24/7" scenario. Since specific heat of weater is essentially independent of temperature, there is no difference between, say, heating the same amount of water for 20 degrees (say from 84 to 104) in one go or heating it up 2 degrees (say from 102 to 104) 10 times.
