Good quality, safe and durable?

1. Capacity selection

The capacity selection is mainly based on the number of family members and water use habits. Generally speaking, the more people in the family, the larger the capacity of the water heater required. For a family of two, choose a 13-liter gas water heater. For a family of three or more, it is recommended to choose a 16-liter gas water heater to ensure that the hot water supply for the kitchen and bathing can be met at the same time.

2. Type selection

The common types of gas water heaters on the market currently include forced exhaust, balanced, and condensing.

Forced exhaust: more common, but cannot be installed in a confined space.

Balanced: high safety, can be installed in confined spaces such as bathrooms, but the price is higher.

Condensing: higher thermal efficiency, but the price is relatively high.

3. Water tank material

The material of the water tank is directly related to the service life and heating efficiency of the water heater. Common water tank materials include stainless steel and oxygen-free copper.

Stainless steel: corrosion-resistant, high temperature-resistant, good thermal insulation, but relatively weak thermal conductivity.

Oxygen-free copper: excellent thermal conductivity, strong corrosion resistance, but relatively high price.

4. Fan configuration

The fan configuration mainly depends on the fan position and fan structure.

Top fan: slightly lower cost, strong exhaust capacity, but low thermal efficiency, relatively short life.

Bottom fan: high thermal efficiency, longer life, and higher safety.

5. Temperature control method

The temperature control method is directly related to the constant temperature performance of the water heater. At present, the mainstream temperature control methods on the market are gas proportional valve adjustment, water and gas dual adjustment, and water volume servo.

Gas proportional valve adjustment: Control the water temperature by adjusting the gas size, but the constant temperature effect is relatively general.

Water and gas dual adjustment: On the basis of the gas proportional valve, a water volume adjustment device is added, and the constant temperature effect is improved.

Water volume servo: It can actively adjust the water volume of water inlet and outlet according to the instructions of the CPU, and the constant temperature effect is the best.

If conditions permit, it is recommended to choose a gas water heater equipped with a water volume servo.
