Immersion heater - economy 7 timer wiring

Former Community Member
Former Community Member
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

    Been here almost a month, from day 2 ive created myself an "electricity spreadsheet" and was putting down the usage. it came to about 2kwh a day and 6 a night. did this for a week. 

    - i believe ive mentioned it in the post that i know the electricity goes against the night rate as ive set the controller up that way. the heating of water goes from 5am to 6.20 which is still the night rate. im just concerned it devours somehow way more than it should. need to start measuring again to doublecheck i guess
