Hi
I had a smart meter installed recently and I am finding something strange with my Quantum Storage Heater.
Prior to the installation I was on a Economy 7 rate and my heater would come on at 12am and off at 7am to charge. I knew this due to the LED light on the switch turning on. This occured during my offpeak time, as also confirmed by meter usage.
Now, still on Economy 7, I am observing the heater isn’t coming on until 3am and the light stays lit up until 10am. I have confirmed my offpeak time on the smart hub is active at 12am onwards (I can see the hourly rate changes over) but this isn’t activating or communicating with the heater. And between 7am and 10am, despite the LED light being lit up there is no usage so it isnt actually using my on peak time (again the hub confirms this from 7am onwards), which of course is good.
But it seems the heater has gone out of time. I have checked the settings on the heater and it shows the off peak tariff time is 12am to 7am. This leads me to understand the heater isn’t getting the opportunity to have its full period of charging, and after 7am its trying to keep charging but is getting no power.
So something seems to be confusing either the meter or the heater,
Could anyone shed some light on this, as it worked as expected for years until I had the smart meter installed.
