What type of meter is used to bill energy for electric storage heaters in a domestic premises?

Explanation:
Storage heaters rely on cheaper off-peak electricity, usually overnight, so the billing needs to differentiate energy used at different times of day. An analogue day-and-night kWh meter provides two separate readings—one for daytime use and one for nighttime use—so the energy used to charge storage heaters can be billed at the appropriate lower off-peak rate. This dual-rate metering is the classic setup for this purpose. A digital smart meter can handle time-based tariffs too, but the question specifically points to the analogue two-rate arrangement. A single-rate meter would not distinguish between day and night usage, and a battery-powered meter isn’t used for this billing purpose.
