If you have electric hot water heater they take over an hour to heat up.So you must plan you day.Here in the states we get charged more for peak usage hours such as around dinner time. You will need to leave it on for a few hours and get your chores done, if you turn it on and off a few times a day it will cost you as much as leaving on all day Good luck
