Hi Everyone,

Thank you to all those who helped last year regarding Air Source heat pump as my oil boiler went down and i was having trouble with my housing association about when it was going to be installed etc. That was in May last year.

Fast forward to this year we now have a heating system ....its Storage heating and I spoke to OVO regarding all this being changed in January this year apparently yes then at the last hour it was no. Ok so I tried to look for a different company that do Economy 7 tariff.

Found one but now OVO don't want to let me go due to a huge bill which I have due to it being wintertime and having to use electric heaters due to no heating system can anyone advise me what to do obviously I didn't really want to leave but ....its a case of having to but then if OVO did Economy 7 or something similar I wouldn't have to.

... will Viv1966 be able to get a duel tariff like Economy 7 with the meter setup they have ?

If you’ve been advised that we can’t switch you to Economy 7 (which is generally the case)

We can’t tell whether this meter is capable of switching an offpeak circuit on and off. Even if it did have the internal switch necessary, there would have to be an external contactor to do the actual power control.

…

It seems that the magic use-excess-solar-generation-to-charge-heaters system only works if the heaters are wired to a constant circuit (i.e. not having the charging bit separate from the control bit so charging only happens during offpeak hours). Again, we can’t tell whether this is Viv’s arrangement. It involves installing some extra bits and bobs including a CT clamp, all included in the optional Solar Box.

As @Firedog suggests, a separate supply is not needed for these
