What does nfc function of water heater mean?

It is realized by its own patented H valve. By installing the farthest end of domestic water through this assembly, cold water can be prevented from flowing into the hot water pipe, thus achieving the purpose of circulating heating of hot water. No matter how long the pipe distance is, the hot water can be achieved by turning on the tap for one second.

Ordinary zero-cooling water heaters need circulating pumps and return pipe, which are usually embedded before renovation. Obviously, it was impossible to take into account the cool home when decorating more than ten years ago. If we want to realize the function of zero cold water without considering redecoration, we can only start with the design of the equipment itself.

Matters needing attention in the use of water heater

For families who don't often use electric water heaters, the frequency of use is not high. In such a family, electricity is turned on one hour before bathing, and the water heater is turned off after bathing, and the water heater is turned off at ordinary times. In this way, the power consumption can be kept at a minimum, thus reducing the electricity bill to the greatest extent.

For families who often use electric water heaters, if the kitchen and bathroom use a water heater at the same time, hot water is used for cooking, washing dishes and bathing. Keep the water heater in a constant state, and adjust the hot water temperature according to the frequency of use and the amount of hot water. When the dosage is small, the temperature can be lowered a little, and when the dosage is large, it can be raised a little.
