Offpeak (controlled load) electricity supply Hardwired dedicated circuit electricity supply) Some utility providers offer discounted electricity prices for dedicated circuits, including water heating that can be controlled by the utility. Availability depends on meter type, meter configuration and available tariffs. Power to your water heater is provided between a defined time period only. This is usually determined by the distributor, and must be hardwired to the dedicated circuit. At prescribed periods as detailed by your utility provider. Dedicated circuit off peak are not suitable for solar systems with a gas booster, or with circulation pumps.
