Hi,
My new hot water cylinder, unvented type, has two electric immersion heaters. I need a controller which will do two things:
1. automatically turn on and then automatically turn off the lower heater at night, during the Economy 7 hours
2, allow me to use only the upper heater as a booster during the daylight hours when I need to.
My only experience of such a controller was many years ago and I found it very complicated to use. I'd be grateful if someone could advise me on a simple device that will do what I want.
Cheers
