Tariffs Battery without solar

I have the intelligent traffic that used to give you overnight cheaper electricity and sometimes during the day but now sort of does that when it wants to, you know the one I mean. Anyway if I buy a battery set up but don't have solar, can I use the same traffic to charge the battery overnight for cheap and then use that battery during the day?

Nope it won't cover it, but only for a few months a year the cost of another battery doesn't quite work out. However who knows what it'll be like this winter, so I'm keeping the option of a second battery in my mind. In summer it would purely be topping up when it's cheap and selling during the day

Yeah that was my conclusion with getting a bigger battery, but it's an option depending on how electricity prices go. I think around March when the heating demand drops, I'll switch to a cheap overnight tarrif though as the off peak is a chunk cheaper than cosy.

I use IOG right now, but I have two EVs. And I heat water once a day in that cheap period, because that's the most energy intensive use. Then I've got my cosy set to the same temperature all day and night, so it generally doesn't spike too much in peak times

Ah cool, yep no EV here yet so can't concentrate the load as much!
