Combustion heater has settable time switch and control circuit to maintain heater in active or inactive position

摘要

The combustion heater has a combustor without a chimney and with a control switch (20) for adjustable time setting. A control (3) cooperates with the timing switch so that the latter changes the control from a first operating state, such as a heating state to a second state, such as a non-operating state, at a first switching point controlled by the timer. Claims include a switch for a heater using the method.
