High Performance for Modern Homes

PHNIX airNova water heater uses R134a refrigerant and delivers hot water up to 140°F (60°C), meeting diverse household needs from showers to kitchens. With an ultra-quiet operation of just 48 dB(A), the system ensures comfort without noise disruption. Designed for both new construction and retrofit projects, it provides distributors and installers with maximum application flexibility.

Maintenance is simplified through a duct adapter that converts a large duct into a small duct for easy connection and flexible installation. All serviceable parts and condensate lines are front-facing, allowing for quick maintenance by simply removing the front cover—no need to move the unit.
