Before diving into the best smart thermostats, it’s important to understand what heat-only systems entail.

Smart thermostats bring a host of advantages to heat-only systems. They provide precise temperature control, adaptive learning, and the ability to manage your heating system through smartphone apps remotely.

Smart thermostats optimize energy consumption and save you money on utility bills by intelligently adjusting temperatures based on your preferences and schedule.

The Nest Learning Thermostat has gained fame for its sleek design and learning capabilities. It adapts to your schedule, automatically adjusting temperatures to match your habits.

Its compatibility with heat-only systems makes it a great choice. The Home/Away Assist feature senses your presence, ensuring your home is always comfortable.

The Nest Learning Thermostat has been around for a while but is still one of the best smart thermostats. Like many who chose it, I liked its clean, high-end aesthetics and the promise of having more control over my heating system and the temperature in individual rooms.

I was hesitant at first about the integration process despite being attracted by Nest’s promises. My house is more than 120 years old. Even though the heating system is newer, it’s still a little geriatric. A Wi-Fi-enabled, AI-based, smart assistant-communicating thermostat connected to my home and expected to work perfectly with a heating and cooling system that’s been around for 20 years caused some cognitive dissonance that made me wonder if this could work.

Although there were a few bumps along the way, the installation process was positive. It taught me how well cutting-edge systems can integrate with legacy infrastructure when designed correctly. I won’t spoil the ending.


  • Clean, simple aesthetics

  • Wide-ranging compatibility, even with older systems

  • Excellent voice assistant support

  • Reliable automated temperature control


  • Lack of granular notification controls

  • Initial training can result in some chilly/sweaty times until it gets a grip on your preferences.

The Honeywell Home T9 Thermostat boasts a responsive touchscreen and geofencing technology. Its wireless Smart Room Sensors provide balanced comfort by considering temperature conditions across different areas. This thermostat also offers energy-saving insights to help you make informed decisions.

Using this kind of feature was the first feature offered by a consumer-based smart thermostat, Ecobee.
