Storage heaters on the ring main

[EBH]

I would like to fit storage heaters in my small flat. There is no economy 7 unit, so I would like to reduce costs by connecting to the existing ring main. I have four questions:

1. Is it "legal" to connect storage heaters to the ring main?
2. What (if any) is the power limit?
3. How should I do it - spur?
4. If connected to the normal consumer unit/meter, does the stoage heater still use cheap rate electricity?

Any advice would be gratefully recieved

Hi, not advisable to fit such large fixed loads to existing ring, would need local time clocks to switch each one on at 'off-peak' times, which do not automatically attract lower charge rates. You must get a dual rate meter fitted and agree a tariff with your supplier, regards
