   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 ...

5. Electric boiler - Wikipedia

   en.wikipedia.org/wiki/Electric_boiler

   A heat exchanger brings the heat from the burner to the water. Its job is to bring heat to the water without having contact with the water, similar to boiling water in a pot. An exhaust stack takes the hot gases and transfers them away from the boiler. Boiler controls are there to make sure the hot water or steam is produced in a safe way. [5]

6. Tankless water heating - Wikipedia

   en.wikipedia.org/wiki/Tankless_water_heating

   Maintaining constant shower temperature: Similarly, unlike with a tank heater, the hot water temperature from a non-modulated tankless heater is inversely proportional to the rate of the water flow—the faster the flow, the less time the water spends in the heating element being heated. Mixing hot and cold water to the "right" temperature from ...

7. Electric water boiler - Wikipedia

   en.wikipedia.org/wiki/Electric_water_boiler

   An electric water boiler is a device comprising a water reservoir equipped with a heating element positioned at the bottom. While some models offer the convenience of multiple temperature settings, others are integrated into larger water systems capable of boiling water and dispensing it in various forms: hot, cold, or lukewarm.
