Away for a week, hot water on or off?

I will look into getting a timer for it, I just hope the landlord doesn't notice/care.But it doesn't need to be on for the full seven E7 hours-the last two hours should be more than enough to heat a full tank.
I guess I am going to need a battery powered one, because the supply is only live during E7 hours. Any mechanical one will just lose its time when the supply goes dead.0 -
The timer idea might be a no-go right from square one, as I cant seem to find one that doesn't need a constant supply to keep the timer running while the E7 fuse box is de-energised.
I do have a separate supply I could use, but all the timers seem to run from the same supply they are switching.0 -
The timer won't save much. If the cylinder is well insulated it'll heat for the first 2 hours then switch itself off. It will only come on again in the 7 hour period if you use some hot water which is unlikely at that time of night.The timer idea might be a no-go right from square one, as I cant seem to find one that doesn't need a constant supply to keep the timer running while the E7 fuse box is de-energised.

Well tbh, that is what I thought, but others on this thread seem to think otherwise, and I always like to take on board as much advice as possible.The timer won't save much.

Agree with HappyMJ that it won't lose much by having it on for the full 7 hours.
If it is well insulated it really shouldn't lose more than 2kWh in 24 hours with water at 65C. So even if it lost 3kWh in 24 hours that is less than a kWh a night(say 6p)
Also for much of the year that heat isn't lost as it heats the fabric of the house - a mini-storage heater!0
