Product Q&A

Q:What is a balanced-flue gas water heater?

A balanced flue gas water heater adopts double-layer coaxial flue pipe. It draws all combustion air from outdoors and exhausts flue gas outdoors. With fully-sealed structure, it does not consume indoor air. It is the only gas water heater permitted by national standards for bathroom installation.

Q:What's the main difference between balanced-flue and forced-exhaust water heaters?

Balanced flue model: draws air from outdoors, fully-sealed unit, suitable for bathroom installation, requires coaxial through-wall flue pipe. Forced exhaust model: draws air from indoor room, flue gas vented outside. Never install in bathroom, only for kitchen or balcony.

Q:Do I need to keep the bathroom window open with a balanced-flue water heater installed?

The heater consumes no indoor air for combustion. Still, basic bathroom ventilation for human breathing is recommended, not for the water heater.
