Who Should Buy A Smart Thermostat

Smart thermostats are the way of the future, and every home should upgrade to one eventually. The energy savings and convenience are hard to pass up. People may at first be intimidated by the thought of purchasing a smart thermostat, thinking that they are difficult to install and complicated to control, but those fears couldn’t be further from the truth.

When replacing an old thermostat or upgrading a home heating system, everyone should consider a new smart thermostat for their home. With a smart thermostat, a person can manually control their heating and cooling, program the system to consistently operate in a specific method, or set the system to automatically adjust the household climate according to the data it gathers about your home.

Important Features to Consider

There are a few important considerations to think through before purchasing a smart thermostat.

  • Type of HVAC system. It is vitally important to know how your home heating and cooling system works before purchasing a smart thermostat. Some thermostats are compatible with only a limited number of home heating solutions, while others claim to be “universal” when they actually only work with the most common types of HVAC systems. Electric baseboard heaters function differently than oil radiators and forced air systems. Understand how your home climate system works before choosing a smart thermostat to control it.
  • Your exisiting smarthome setup. While there are plenty of smart thermostats that will work with a variety of smart home setups, certain brands like to stick together and are not universally accepting of all smart devices. Alexa, Google Assistant, and Siri are the most popular smart home voices we’re all accustomed to hearing, and they don’t always work well with each other. There are smaller smart home companies with proprietary products as well. Make a plan about your complete smart home setup before deciding on your smart thermostat as you may be locking yourself into a specific brand’s products going forward.
  • Voice control. This feature is common among smart thermostats, but it’s not a feature in every product across the board. Virtually every smart thermostat can be remotely controlled through a smartphone, but if you need that extra convenience of voice control, make sure you purchase a smart thermostat that has that feature.

Frequently Asked Questions

What is a smart thermostat and how does it work?

Smart thermostats are thermostats that can integrate within a smart home system, connect to the Internet, and connect to other smart devices such as smartphones and tablets. They install and operate similarly to traditional and manually programmable thermostats, but have additional functionalities.

Most smart thermostats can be interacted with at the physical device itself or through a smart device via a downloadable app. Smart thermostats often include the use of sensors to monitor household temperatures in order to “learn” the home and adjust heating, cooling, and humidity levels as necessary.

What are the advantages of a smart thermostat?

Smart thermostats can be operated remotely through a smartphone, allowing users to adjust settings and inspect temperature data from wherever they may be. These apps often have usage reports that detail energy consumption and costs which allow homeowners to make more informed energy decisions.

The use of additional sensors gives a smart thermostat the information it needs to automatically control household temperatures without human input. Studies show that automated smart thermostats are much more energy-efficient than manual or programmable thermostats, which means homeowners who utilize smart thermostats save money and have a lower carbon footprint.

Do smart thermostats really save you money?

Absolutely! Studies have consistently shown that consumers can save big on their energy bills with smart thermostats. For example, in a study conducted by Nest it was concluded that homeowners could save 12% on heating costs and 15% on air conditioning costs by switching to a smart thermostat.

Are smart thermostats easy to install?

Installing a smart thermostat is no different than installing a traditional or programmable thermostat. Most smart thermostats are easy to install and claim that they can be fully installed in under 30 minutes. You will, however, want to make sure that the smart thermostat you purchase does work with your home’s specific type of climate control before attempting to install. In addition to the typical wiring and mounting, smart thermostats will also require a quick WiFi and/or Bluetooth connection to complete the installation process.
