Hi
My immersion heater is on a timer to take advantage of economy 7. Its a 144 litre tank and is currently timed to go on at 2am until 7am. My question is, does the heater need to be on this long during the night? If I was to change the timings from say 3am to 6am to save a bit would it actually make any difference to the amount of hot water I had? If the actual water only takes an hour or so to actually fully heat (guess) then why would I need to keep heating up for longer if its stored in the tank all day?
Thanks
