At present, gas water heaters are commonly divided into flue gas water heaters, forced exhaust gas water heaters and balanced gas water heaters. The flue gas water heater uses natural smoke exhaust to exhaust the flue gas to the outside. The forced exhaust water heater uses forced exhaust or air blast to exhaust the flue gas outside. The balanced water heater is a gas water heater with both air inlet and exhaust outside. Features: fast heating, large water yield, stable water temperature, less scale formation and small land occupation. Working principle: using gas as fuel, heat is transferred to the cold water flowing through the heat exchanger by burning and heating, so that the cold water becomes hot and hot water is prepared.

The storage water heater is divided into closed type Electric water heater And open type electric water heaters. At present, the common water storage water heaters on the market are closed type water heaters, which can supply water in multiple ways. They can be used not only for shower and bath, but also for washing clothes and vegetables. Features: clean, no odor, no need to install in different rooms, the larger the volume, the more hot water. Working principle: When a certain amount of water is heated to the temperature set by the user, the temperature controller is started to maintain the constant temperature, so that the user can adjust the water temperature by opening the water mixing valve.

Instant type Intelligent thermostatic water heater There are two types: instant and multi-mode. The multi-mode water heater has one more outlet tank than the instant intelligent thermostatic water heater, which can meet the needs of large shower and bathtub. Features: instant heating, energy saving, safety and environmental protection, compact size, unlimited hot water volume. Working principle.

The manufacturer of fast heating intelligent thermostatic water heater said that the safety of household appliances is of course important. The heater depends on its heating body, the electric water heater depends on its leakage protection function, and the gas water heater depends on its carbon monoxide alarm device. In the past, there were direct discharge, forced discharge and balanced gas water heaters. Because the direct discharge gas water heater directly discharged the carbon monoxide containing exhaust gas after burning the gas into the room, it was prohibited by the state to produce and sell.

The heating body used in the water storage electric water heater is the electric heating tube used to boil water before. After the heating tube is electrified in the water, the water is heated by converting electric energy into heat energy. This traditional heating method will affect the heating efficiency and safety when the heating pipe is corroded or covered by scale because the heating pipe is immersed in water and water and electricity are not separated.

        Instant electric water heater The requirements for heating body are very high. Its heating body includes non-metallic heating body and metal heating body. The metal heating body is divided into cup heating body and cast aluminum heating body. Among these heating elements, only the cast aluminum heating element is separated from water and electricity, which can truly ensure the safety of users.
