Hi all,
I've been having an eternally long nightmare, of which I have only just realised stems from a nest install from back in 2019.
As it turns out, my electricity bill woes are due to my unvented cylinder using its built in (3kw!!) emergency heater, rather than calling for heat from the boiler! So for 2 and a half years, all of my hot water has been heated from this electric backup (Yes, my electricity bill has been stupidly high and I have been going crazy trying to figure out why! I had never thought of this as I thought the hot water was working fine from our gas boiler!)
I have since had a qualified nest technician come out to replace a faulty heat link around a year ago, but I still have the issue.
Does anyone have a clue why my nest / boiler / cylinder aren't working together? My HW schedule in my nest is set to 24/7. The cylinder just isn't calling for heat from my boiler for some reason.
I thought my stupidity maybe mis-wired something, but surely the qualified engineer that came to replace my faulty unit would have spotted an error??
So does anyone have any suggestions for my circa £5000 mistake?
Thanks in advance
