Is the thermostat set at a suitable temp so that consumption is
minimal if water is not being run off?

Good idea; I've already adjusted it up quite a lot but I might as well
max it out as a trial, I'll check it's not scalding.


I was more concerned that you may have it too high and be wasting energy.
The hotter it is = the greater the losses, but the less you use.

As the problem is caused by running out of hot water, getting it hotter
and so using less of it, may solve the problem.

Is this flat in a hard water area though ?.
A timer that gives two periods of 30 mins per day, set to occur just
before the most common usage time, with a boost override might seem
a better idea.
