    See how the Rinnai EnergySaver® Direct Vent can work for you.

    With a Rinnai EnergySaver® Direct Vent Wall Furnace, you can be assured of consistent comfort and warmth. Designed to constantly monitor room temperature, Rinnai's unique modulating technology can respond immediately to even the smallest temperature fluctuations.

    How It Works

    • Constantly monitors room temperature 2"? (5 cm) from the floor
    • Consistently detects temperature changes of less than 1° F
    • Within seconds, the Rinnai EnergySaver® Direct Vent Wall Furnace begins to gently heat the room
    • Fan speed and BTU output increase as necessary to reach the preset temperature
    • As the room reaches the desired temperature, the EnergySaver® Direct Vent Wall Furnace reduces fan speed and BTU output
    • In case of a sudden influx of cold air, the EnergySaver® Direct Vent Wall Furnace automatically adjusts fan speed and BTU to quickly restore warmth to the room.

    Heat is distributed evenly and heat loss is minimized since Rinnai EnergySaver® Direct Vent Wall Furnaces require no ductwork.
