How do instant water heaters achieve "instant heating" and "no water storage required"?

I. How Instant Water Heaters Work
The "instant heating" feature of an instant water heater relies primarily on its instant heating and no water storage design. Its operating principles are as follows:

1. Instant Heating
When a user turns on the faucet, cold water flows directly through the heater's internal heating element (such as a metal heating tube or heat transfer tube). This is then rapidly heated to the set temperature through electric or gas heating.

Electric Heating: High-power electric heating elements (such as copper or stainless steel) rapidly heat the flowing cold water, achieving "instant heating."

Gas Heating: Cold water is heated through gas combustion and is suitable for gas water heaters.

2. No Water Storage Design
Instant water heaters do not require a water tank, eliminating the need for preheating or insulation. This avoids the energy consumption and scale buildup associated with the water storage, insulation, and heating processes of traditional storage water heaters.

Tankless: Instantaneous water heaters instantly heat running cold water, eliminating the need for water storage. Therefore, there's no need to wait for the hot water tank to fill up or maintain heat.

No Scale: Since the water is heated by "live water," it avoids the scale and bacterial growth problems associated with long water storage periods in storage water heaters.

3. High Energy Efficiency: Instantaneous water heaters instantly heat only the hot water actually used, eliminating the "standby energy" and "preheating energy" of traditional storage water heaters, resulting in greater energy efficiency.

II. How They Achieve No Water Storage: The "no water storage" feature of instantaneous water heaters is primarily reflected in their structural design and operating method:

1. Tankless Design: Instantaneous water heaters lack a water tank, eliminating the need for preheating or maintaining heat, and eliminating the need for concerns about corrosion and scaling.

Tankless: Instantaneous water heaters instantly heat running cold water, eliminating the need for water storage. Therefore, there's no need to wait for the hot water tank to fill up or maintain heat.

No Scale: Because the water is heated by "live water," it avoids the scale and bacterial growth problems associated with long-term water storage in storage water heaters.

2. Instant Heating: Instant water heaters instantly heat running cold water, achieving instant heating. There's no need to wait for the hot water to fill or maintain heat.

No Preheat: Instant water heaters don't require preheating, so there's no need to wait for the hot water to fill or maintain heat, saving energy and space.

No Scale: Because the water is heated by "live water," it avoids the scale and bacterial growth problems associated with long-term water storage in storage water heaters.

In addition, some models are equipped with a leakage detection coil that quickly cuts off the power supply in the event of a leakage.

Dry-boil protection: This feature automatically cuts off the power supply when there is no water or insufficient water in the water heater, preventing damage or fire caused by dry-boil. This feature works by detecting water level or temperature fluctuations.

Scalding protection: Instantaneous water heaters typically have scalding protection, which uses an intelligent temperature control system to control the water temperature and prevent burns caused by excessive water temperature. Some models also feature a constant temperature function to ensure a stable water temperature and enhance user comfort.

Overheat protection: Instantaneous water heaters have a built-in temperature control system that monitors the water temperature in real time. If the water temperature exceeds the set safety range, the system automatically cuts off heating to prevent accidents caused by overheating.

Electric shock wall technology: This technology separates the water in the water heater into sections to prevent short circuits and other electrical hazards, ensuring user safety.

Multiple Safety Protection Systems: Instantaneous water heaters are typically equipped with multiple safety protections, including overcurrent protection, overtemperature protection, leakage protection, and overpressure protection, to ensure timely response in abnormal situations and protect users.

Grounding Protection: Instantaneous water heaters are typically equipped with a grounding protection feature, ensuring that in the event of a leakage fault, the ground wire effectively conducts the current, preventing electric shock accidents.

Water-Electricity Separation: Instantaneous water heaters utilize a water-electricity separation design between the heating element and the water supply, ensuring that the water does not directly contact the heating element, minimizing the risk of leakage.

Intelligent Control System: Modern instantaneous water heaters are typically equipped with an intelligent control system that monitors the operating status of the device in real time, predicts and alerts potential safety hazards, and enhances user safety.

What maintenance precautions are required during daily use?
