Efficient on-demand comfort for modern homes

APUS presents a natural gas tankless water heater designed for indoor installation, delivering hot water when you need it. With 95,000 BTU of heating capacity and a 4.42 GPM flow, the unit can support two showers and a sink at once while maintaining steady temperatures.

Precision and consistency you can feel

Smart sensors and CPU-driven control monitor flow and temperature in real time, keeping water within ±1°F of your chosen setting. You can dial in a comfortable range between 95°F and 140°F for showers, washing, and more, even when multiple fixtures call for hot water.
