  "textContent": "The resistance heater (10) includes a heating component (13) connected between two spaced contact rods (12a,12b) such that electric current flows through the heating component if an electric voltage is applied between the contact rods. A sensor (24) detects at least one parameter of liquid in a liquid system. An analyzer unit (18) is connected to the sensor for analyzing the determined liquid parameter to switch ON and OFF the heating component. Independent claims are also included for the following: (A) a liquid system; (B) a liquid level detecting method; and (C) a liquid temperature detecting method.",
