I understand you have to wire these things into your immersion switch to get them to function.
Can I heckle my energy supplier to do this? I don't want to be calling out an electrician as no doubt the cost will suck big time.
My immersion switch is in the kitchen and heats the water for both the bathroom & the kitchen. I read that if you put it on for 3 hours during the night when it's cheap, it should last up to about the early evening.
Has anyone managed to install one of them their selves before?
