We moved into an all elec. flat a year ago. Since then we have been trying to get OVO to instal a meter wich sends a signal to our Gledhill hot water boiler when the cheap periods occours, (so that it can heat its thermal store on E10 rate). After 4 meters installed by OVO then finally admitted that their installer does not fit this type of meter! EDF do but their rates are prohibitive.
How does your boiler turn on in the cheap periods?
