Most thermopots use two separate heating elements or a single element with two circuits: Main Element ( EK1cap E cap K 1 ): High power (700–900W) for the initial boiling phase. Keep-Warm Element ( EK2cap E cap K 2
) that permanently breaks the circuit if the thermostats fail and the pot overheats dry.
Once boiling, the main thermostat opens its contacts. The circuit then redirects power through the secondary "Keep-Warm" TÉN or a control relay.
A manual bellows-style pump that works without electricity. 2. Operational Logic (How the Circuit Works)
