  • Control system for charging and discharging an electric storage heater
    Patent number: 4213032
    Abstract: The invention relates to an electric storage heater assembly which includes a core and a resistance heater for the core. A low tariff period switch and a charging switch are in series with the resistance heater. A triggering unit, which includes an integrator in one embodiment, and an integrator and comparator in a second embodiment, operates the charging switch. A feed circuit for charging the integrator is responsive to the indoor temperature and the unregulated heat loss from the core. A scanning circuit which produces the opposite effect is responsive to the regulated heat loss from the core and the outdoor temperature. The scanning circuit can be connected to either the integrator in one embodiment or to the comparator in the other embodiment.
