What temperature settings are recommended for Rinnai heaters?

April 5, 2026

Quick Answer

Rinnai heaters are typically recommended to be set between 68-72 degrees Fahrenheit when occupied and 55-60 degrees Fahrenheit when unoccupied.

Understanding Rinnai Heater Temperature Settings

When it comes to setting the temperature on a Rinnai propane wall heater, it’s essential to strike a balance between comfort and energy efficiency. Rinnai recommends setting the temperature between 68-72 degrees Fahrenheit when the space is occupied, as this allows for a comfortable living environment while minimizing energy consumption.

Factors to Consider When Setting Temperature

Several factors can influence the ideal temperature setting for your Rinnai heater, including the size of the space, insulation levels, and personal comfort preferences. If you have a larger space or poor insulation, you may want to set the temperature a few degrees higher to ensure the space remains warm. Conversely, if you have a well-insulated space or prefer a cooler temperature, you can set the temperature lower.

Temperature Settings for Unoccupied Spaces

When your space is unoccupied, it’s recommended to set the temperature between 55-60 degrees Fahrenheit. This helps reduce energy consumption and prevents overheating, which can lead to equipment damage and increased energy bills. Additionally, setting the temperature lower when the space is unoccupied can also help maintain a consistent temperature when the space is occupied again, reducing the need for constant heating and cooling cycles.
