How to Choose the Right Programmable Thermostat for a Gas Furnace

Choosing the right programmable thermostat can significantly impact your home’s comfort and energy bills. Here’s a breakdown of key features to consider when selecting a thermostat for a gas furnace:

Compatibility with Your System

The most crucial factor is ensuring the thermostat is compatible with your existing gas furnace setup. Most programmable thermostats work with standard forced-air systems (gas, oil, or electric), hot water, and steam. However, compatibility isn’t universal. Specifically, avoid thermostats that don’t work with electric baseboard heat (120-240V) if you have that system. Multi-stage furnaces require thermostats specifically designed to handle them (like the Multi-Stage Programmable Thermostat 2H/2C), while simpler systems work with basic 1H/1C models. Always double-check the thermostat’s specifications and your furnace’s documentation before purchasing. Failing to do so can result in a non-functional thermostat or, worse, damage to your furnace.

Programming Flexibility & Features

Programmable thermostats offer varying levels of scheduling control. Consider your lifestyle and how much customization you need.

  • 5-2 Day Programming: (like the Honeywell RTH6360D) offers separate schedules for weekdays and weekends, a good balance for many households.
  • 7-Day Programming: (like the Honeywell RTH7600D) allows unique schedules for each day, ideal for irregular routines.
  • Simple Programming: (like the Honeywell RTH221B) is best for those who want basic scheduling without complexity.
  • Smart Features: Some thermostats (like the Honeywell RTH6580WF) learn your preferences and adjust the temperature automatically (Smart Response Technology) or offer remote control via a smartphone app. These features can maximize energy savings but add to the cost.

More programming options provide greater control and potential savings, but also require more initial setup.

Display & User Interface

The thermostat’s display and user interface significantly impact ease of use.

Consider who will be using the thermostat and their comfort level with technology. A clear, easy-to-navigate interface will ensure the thermostat is actually used to its full potential.

Power Source & C-Wire Requirement

Most thermostats can run on batteries, but some require a “C-wire” (common wire) for continuous power. The C-wire provides a constant electrical connection, which is essential for Wi-Fi enabled thermostats and some advanced features. If your existing wiring doesn’t include a C-wire, you may need to install one (requiring professional help) or use a C-wire adapter. Battery-powered thermostats are simpler to install but require periodic battery replacements.

Other features to consider include:

  • Filter Change Reminders: Alerts you when it’s time to replace your furnace filter.
  • Humidity Readouts: Provides information about the humidity level in your home (Honeywell RTH8560D).
