Background technique

Current electric water heaters generally have two forms: one is "storage water heater" and "hot water heater". The storage type water heater has a relatively large volume, and has a water storage tank in which an electric heater is provided (this water storage tank is also called a water heater inner chamber, that is, a water-filled electric heating chamber). Preheating and heat preservation are required before use; the electric power is generally small, the electric heating time is long, and there is a certain heat loss.

The instant electric water heater has a fast heating and hot water speed, that is, it is hot, no water storage, small volume, and power saving; small non-metal (smaller thermal conductivity) heating body, small non-metallic heating body and flow rate The higher water contact surface is small, so the temperature of the small non-metallic heating body needs to be very high, and the electric power is at least 5~6KW to ensure normal use. The standard of the Civil Building Design Code JGJ/T-16-92 is that the capacity of entering the house can only reach 5KW (20A meter). That is to say, with this instant water heater, appliances such as air-conditioners and refrigerators should be turned off; and it is necessary to pull a wire for it.
