Although the relevant state departments have already banned the direct-discharge gas water heaters, they can still be used by gas customers. Recently, there have been incidents of casualties in the country due to the use of in-line gas water heaters.

Because the flue gas generated when the in-line gas water heater is burned will be directly discharged into the room, causing carbon monoxide poisoning. As early as 1999, the relevant state departments issued the "Notice on Prohibiting the Production and Sale of In-Line Gas Water Heaters for Baths", prohibiting the production and sale of direct-flow gas water heaters for baths. However, due to the low price and simple installation, such products have been banned in the market. Some residents still use in-line gas water heaters to leave hidden dangers for safety.

In addition, choosing the right and appropriate installation site is also an important prerequisite for safety. The bathroom should not be installed with flue-type and forced exhaust water heaters; no gas heaters of any type can be installed in the living room, bedroom, basement, stairs and safety exits, and cabinets. .
