Different sort of meter, we have a timer to tell our Gledhill when E10 times are. As an aside, our Electramate 2000 needs replacing, and I find that Gledhill no longer provide a like for like replacement – they only do domestic hot water stores. I’m having awful problems finding someone who install me a Thermaflow or McDonald system. There are another 20 in our block, all of which will fail sooner or later. I’d hate to have to move to night storage.
