In winter, always leave your heat on set between 𝟓𝟎∘ 𝐅 and 𝟓𝟓∘ 𝐅. Never turn the heating completely off, as uninsulated pipes hidden inside exterior walls can freeze and burst.
The most popular and highly-rated alternative to the Google Nest is the Ecobee Smart Thermostat Premium. It resolves the main criticisms of the Nest by using wireless room sensors to stop uneven room temperatures, offering built-in smart assistant capabilities (Alexa), and featuring native compatibility with major smart home ecosystems.
Neither thermostat is universally "better," but the right choice depends on your home setup and smart home preferences.
The best smart thermostat depends on your ecosystem, but the universally top-rated models are the Google Nest Learning Thermostat (4th Gen) and the Ecobee Smart Thermostat Premium.

Choosing between ecobee and Sensi comes down to advanced smart features versus traditional simplicity. Ecobee offers premium features like room sensors and advanced HVAC compatibility, while Sensi provides an intuitive, budget-friendly design that feels like a classic thermostat.
Smart thermostats offer great automation and energy-saving benefits, but they can be hindered by a few notable drawbacks. The most common issues include steep upfront costs, complicated installation (often requiring a C-wire), Wi-Fi dependency, and data privacy concerns regarding how your usage habits are tracked.
The best smart thermostats to save money are the Google Nest Learning Thermostat (4th Gen) and the Ecobee Smart Thermostat Enhanced. Both are ENERGY STAR certified, feature geofencing and smart scheduling to stop heating or cooling empty rooms, and will typically pay for themselves within two years.
The most common problem with Nest thermostats is power-related issues caused by a missing "C" (Common) wire. While Nest designs its thermostats to "steal" power from the HVAC system through existing wires, this can cause erratic behavior, dropped Wi-Fi, random system cycling, or a completely blank screen.
The "best" thermostat depends entirely on your smart home ecosystem and heating/cooling setup. However, industry testing and user consensus name Ecobee, Google Nest, and Copeland Sensi as the top overall brands on the market.
The best alternative to the Google Nest is the ecobee Smart Thermostat Premium. It is widely considered the top overall replacement because of its industry-leading remote sensors that eliminate hot and cold spots, seamless integration across all major smart ecosystems (Siri, Alexa, Google), and built-in air quality monitoring.
The "30-minute heating rule" is a highly efficient, money-saving thermostat strategy that involves turning your heating system on 30 minutes before you need a space warmed up, and turning it off 30 minutes before you no longer need it.
No, 68°F is not generally considered cold for a house in winter. In fact, experts at the U.S. Department of Energy recommend 68°F as the ideal, energy-efficient temperature for the winter months while you are awake.
Maintain your thermostat at a minimum of 55°F (13°C) to protect your pipes. While water freezes at 32∘F (0∘C), keeping the ambient air at 55∘F ensures the temperature within your walls and near exterior-facing pipes stays safely above freezing.
The risks of a hacked smart thermostat include inconvenience, higher costs, and exposure of other connected devices. Let's look at these in greater detail and how you can avoid them: Unauthorised control of settings: Hackers could potentially adjust your thermostat's heating or cooling remotely.
To save money in winter, the Department of Energy recommends setting your thermostat to 𝟔𝟖∘𝐅 while you are awake and at home. When you are asleep or away from the house, lower the temperature by 𝟕∘𝐅 to 𝟏𝟎∘𝐅 for eight hours a day to potentially cut your heating bill by up to 10%.
Yes, there are active class-action lawsuits regarding Google Nest products:
Ecobee thermostats are compatible with over 85% to 95% of residential 24-volt HVAC systems in North America, including gas, oil, electric, and dual-fuel systems. They work seamlessly with standard heating/cooling setups, heat pumps, boilers, and multi-speed fans.
ecobee Room Sensor and the next-generation SmartSensor are the only thermostat sensors that detect both temperature and occupancy. They are designed to supplement the temperature and occupancy sensors built into your ecobee thermostat*—unlocking your ecobee's full potential.
Nest Thermostat Alternative
Google Nest officially discontinued support for the 1st and 2nd generation Nest Learning Thermostats. These models no longer connect to the Google Nest or Google Home apps, meaning you can no longer control them remotely. They function solely as traditional "dumb" thermostats.
Whether you should upgrade depends on the generation of your current Nest Thermostat.
When deciding between Sensi and Nest, choose Sensi if you want straightforward, budget-friendly, and highly compatible climate control. Choose Nest if you want sleek design, smart learning capabilities that adjust to your habits automatically, and advanced energy-saving tools.
