Since the 90s of last century, the water heater has become one of the most essential household appliances in China. In the past, people paid more attention to safety, and with the improvement of living standards, the user's choice of water heaters slowly turn to quality consumption, this change led to the upgrading of the entire industrial structure. As the ordinary water heater gradually eliminated by the market at the same time, intelligent safety water heater products came into being.

But there are a wide range of water heaters which make consumers prone to blind selection. At the same time, the improper use of the water heaters also results in carbon monoxide leakage.

However, in real life, the ordinary gas water heater can only be a simple monitoring of carbon monoxide, cannot do comprehensive protection and take actions when gas is leaking.

In order to solve the above problems, Haier learns from the Chang’e II monitoring the gas by a high sensitivity detector and develops a smart double gas security system to monitor carbon monoxide and natural gas on gas water heaters. Once exceeded the standard, it will shut down the gas value and clean the exhaust waste smoke automatically.

Recently, Haier’s new anti-carbon monoxide poisoning Wi-Fi intelligent security gas water heater can monitor the internal and external environment for 24 hours. Once carbon monoxide leakage happened, it will immediately sound and light alarm, and send the information to the binding cellphone.

In this way, family members can monitor home security situation through mobile phone APP on real-time and take actions on time whenever they are. Even if people cannot handle it immediately, the water heaters will automatically shut down the water value, open the fan and discharge the carbon monoxide from the room in 6 seconds

Winsen technology independently developed and produced a variety of gas and carbon monoxide sensor, with high precision, high sensitivity, strong anti-interference ability, widely suitable for commercial, especially civil areas of gas and carbon monoxide concentration detection.
