Immersion heater - economy 7 timer wiring

Former Community Member over 4 years ago

Hello,

I have a honeywell st6400c controller and an immersion heater.

My heater has 2 switches, off and on peak. My concern is that the heating works only with both switches on. Even if its set to trigger at off peak time only, which it does, both switches light up and if I switch off the onpeak one, the heating stops even tho the offpeak is still lit (testing this at off peak hours ofc). Is this correct ? does this not use much more electricity? I was monitoring this and Im sure it goes against the "night" hours, but my worry is that it uses much more power than it should.

Thank you for your advice

Heya,

same way as the tank - via the honeywell controller.

the whole electricity in the house is a bit insane to me. 70+ spotlights bulbs all over the place. at least they can be lowered intensity but still. during covid we had not much choice as we couldnt personally visit and inspect the house to the detail. its not bad as we dont need them lit almost nowhere at any time.
