I have version 0.2 in my London apartment - the bottom element of the water heater is connected to a different electric supply, with a separate meter, with energy that's almost 3 times cheaper than the rest of the wiring energy. The catch? The circuit is powered only when the power company feels like it (i.e. They need to dump excessive power somewhere), but they guarantee 2h power on by day and 6h by night.
Since this is the bottom element, and the top element is controlled by a thermostat (guaranteeing hot water on demand), this is a great setup for both the consumer and the power company!
- throwawaycanada 8y agoWhat an unusual arrangement. Are you allowed to connect other things to that power source?
- ddalex 8y agoI am not sure, I also have a storage heater on the same circuit. Probably I need to speak to the power company if I want to connect a power bank of some sorts, like charging a car. The tariff is called Economy9 for reference. It's not widespread outside London.
- gambiting 8y agoIs it not? I know at least a few people who use Economy9 in Newcastle. And yes, their storage heaters are hardwired to this secondary circuit.
- richjdsmith 8y agoWe're on economy9 in Warwick. As I understand it, the landlord added it fairly recently (within the past decade).
- twic 8y agoI had Economy 7 when i was a student in Oxford twenty years ago. How things have come on - just imagine, by 2040 we may be up to Economy 11!
- laurencerowe 8y agoI had economy 9 heating in the flat I rented in London. It would come on at night and heat up large concrete blocks which would slowly release the heat while I was out at work during the day. Had the drafty Victorian building been properly insulated it might have worked quite well.
