If you don’t understand gas water heater in advance when buying a gas water heater, you will definitely be cheated by the merchants when you go to the mall!

I am a good example. When buying a gas water heater at home, I didn’t just listen to the guidance from the shopping guide, but problems always occurred when I bought it and used it at home.

Today we have summarized what you should pay attention to when choosing a gas water heater, so don’t waste your money!

Buy the water-gas dual-adjustable type instead of the mechanical one

The quality of the constant temperature effect of a gas water heater depends on the built-in temperature control technology. The traditional mechanical temperature control has low accuracy and should be eliminated long ago! Nowadays, water and gas dual-adjustable water heaters are popular. When the water output changes, the firepower and water inflow can be adjusted at the same time. The water pressure and water temperature are constant, making water more comfortable.

Buy a variable frequency fan, not a DC fan

No matter what kind of smoke exhaust gas water heater, there must be a fan, Its quality directly affects the performance and comfort of the water heater. Common water heater motors include DC and variable frequency . It is recommended to choose frequency conversion rather than DC. The variable frequency motor can adjust the working frequency according to the amount of exhaust gas, with stable operation, energy saving, low noise and long service life.

Buy an oxygen-free copper water tank instead of an aluminum water tank

The water tank is the heart of the water heater. If there is a problem with it, the entire gas water heater will basically be scrapped. You must pay attention to its quality when purchasing. The more common ones on the market are copper water tanks and aluminum water tanks. Try to choose copper water tanks if possible. They have strong anti-oxidation and corrosion resistance, high heat transfer efficiency, and are more durable than aluminum water tanks.

Buy a V-shaped fire exhaust, do not buy a T-type fire exhaust.

The fire exhaust mainly plays the role of combustion and heating. Its shape will affect the heating efficiency and effect of the gas water heater. Common ones include T-type, V-type, Z-type, and U-type fire exhausts. Among them, the V-type fire exhaust has the best performance. It has strong flame focusing ability, high combustion efficiency, reduced exhaust gas emissions, and good hot water constant temperature effect.

As for the external design of the gas water heater, such as the shell and functions, you can choose and buy according to your personal usage habits, and you do not have to blindly follow the trend.
