Frequently Asked Questions

Q: How do I choose the right gas water heater capacity for my household?

A:
The capacity you need depends on the number of family members and your hot water usage patterns. For example, if you have a small family with normal hot water demand, a model with a rated hot water capacity of 12 - 16L/min (like some models in our range) might be sufficient. But for larger families or those with higher hot water consumption, such as frequent bathtub filling, you may need a model with a higher capacity, like 18 - 20L/min.
Q: What's the difference between a forced-draft and a balance-type gas water heater?

A:
A forced-draft gas water heater uses a fan to exhaust combustion gases to the outside. It requires an exhaust flue connected to the outside. In contrast, a balance-type gas water heater has a sealed combustion chamber. It draws in outside air for combustion and exhausts gases outside through a coaxial flue. This makes it safer for installation in areas with limited ventilation, as it doesn't consume indoor air for combustion.
Q: How can I ensure the safety of using a gas water heater?

A:
Our gas water heaters are equipped with multiple safety features. Most models have a “7 + 2” maximum protection system, which includes measures like over - temperature protection, anti-dry-burning protection, and flame-out protection. Additionally, features such as error warning systems and water-pressure release devices further enhance safety. Regular maintenance and inspection as per the user manual are also recommended.
Q: Can the gas water heater maintain a stable water temperature?

A:
Yes, our gas water heaters are designed with advanced temperature control technologies. For instance, micro-flame technology allows for precise adjustment of the flame, enabling accurate temperature control. Smart self-adaptation features can also adjust to changes in water pressure and gas supply, maintaining the water temperature within a narrow range, typically ±0.5℃.
Q: How energy - efficient are these gas water heaters?

A:
Our gas water heaters generally have high efficiency ratings, often exceeding 88%. Models with advanced features like condensing technology can further improve energy efficiency by recovering heat from the exhaust gases. Choosing a high-efficiency model not only saves on energy costs but also reduces environmental impact.
Q: Can the gas water heater work in low-water-pressure conditions?

A:
Some of our models are specifically designed to work in low-water-pressure environments. They have a low-water-pressure startup feature, which allows them to activate and operate normally even when the water pressure is relatively low. This ensures that you can still enjoy hot water in areas with limited water pressure.
