2. Water heating - Wikipedia

   en.wikipedia.org/wiki/Water_heating

   An 80 US gal (300 L; 67 imp gal) electric storage tank water heater was able to have a minimum energy factor of 86% under the pre-2015 standard, while under the 2015 standard, the minimum energy factor for an 80-gallon electric storage tank water heater is now 197%, which is only possible with heat pump technology. This rating measures ...

3. Thermostat - Wikipedia

   en.wikipedia.org/wiki/Thermostat

   The power through the thermostat is provided by the heating device and may range from millivolts to 240 volts in common North American construction, and is used to control the heating system either directly (electric baseboard heaters and some electric furnaces) or indirectly (all gas, oil and forced hot water systems).

4. Electric heating - Wikipedia

   ANITA Mk VIII. The ANITA Mark VII and ANITA Mark VIII calculators were launched simultaneously in late 1961 as the world's first all-electronic desktop calculators. [1] [2] Designed and built by the Bell Punch Co. in Britain, and marketed through its Sumlock Comptometer division, they used vacuum tubes and cold-cathode switching tubes in their logic circuits and nixie tubes for their numerical ...

6. Heating element - Wikipedia

   en.wikipedia.org/wiki/Heating_element

   Home Appliances: Common household appliances such as ovens, toasters, electric stoves, water heaters, and space heaters rely on heating elements to generate the necessary heat for their functions. Industrial Processes: In industries, heating elements are integral to processes such as metal smelting, plastic molding, and chemical reactions that ...

7. Electrical resistance heating - Wikipedia

   en.wikipedia.org/wiki/Electrical_resistance_heating

   Electrical resistance heating is used by the environmental restoration industry for remediation of contaminated soil and groundwater. ERH consists of constructing electrodes in the ground, applying alternating current (AC) electricity to the electrodes and heating the subsurface to temperatures that promote the evaporation of contaminants.
