  • As it's currently GMT, the winter time line should point to the current time. There is no need to change it between GMT and BST as the Economy 7 hours do not change with the time. As long as you are on an Economy 7 electricity tariff, then it is the cheapest way to get hot water. Most immersion heaters are 3kw.
  • If you have seperate boost/overnight elements, and if the light came on, it is more likely to be an issue with the element/thermostat. But it would need investigating with a multimeter to be certain.
  • It is set by the installer to be economy 7 hours. Changing it requires opening the unit, so is best done by a professional.
  • The Economy 7 hours are set internally when the unit is installed. The current time can be set by rotating the dial clockwise.
  • I would guess you have two immersion heaters on your cylinder. One at the top for boost and a bottom one for timed. If you are competent to do so, check if power is being sent to the bottom immersion heater when it is timed to be on (E7 hours). If it is, then it is a problem with the thermostat or heater. If not, then the timer is the likely problem.
