Best Smart Thermostat Review- A Smart Device Essential for Energy Savings

The consumption of energy is increasing rapidly because of the various electronic devices that people are using each day. Besides, the rising temperature can add to energy use thus increasing your monthly energy bill.

The good news is you can save energy by using a thermostat in your home. The U.S. Department of Energy stated that you can save around 10% a year by setting your thermostat to 7 to 10 degrees for 8 hours each day.

On the other hand, if you set the traditional or programmable thermostat incorrectly or disable it, you might have higher energy consumption. This problem can now be resolved using a smart thermostat that can automate the temperature of your home thus reducing the use of energy.

What is a smart thermostat?

Best Smart thermostat 2019

A smart thermostat is a device that can manage the temperature of your home wherever you are using another device such as a smartphone or laptop. This device controls the heating and air conditioning of your home in a manner that can be adjusted to the right temperature, which can make you comfortable and save energy.

What are the benefits of using a smart thermostat?

A smart thermostat not only controls the heating and cooling of your home resulting in energy savings but can also do some tasks. Among them are the following:

  • Controls and adjusts the temperature of your home anywhere you are
  • Alters the temperature of your home using your voice as it works with smart speakers
  • Uses artificial intelligence in the case of smart learning thermostats that can automatically adjust the temperature based on your comfort level and occupancy patterns such as when you come and go.
  • Turns off the AC when you leave the room, particularly if you forget turning it off
  • Regulates the temperature of your heater when it is cold
  • Updates you on how much energy you save in a month and tells you how you can save more
  • Provides maintenance reminders and alerts
  • Helps you keep money by conserving energy thus lowering your monthly electric bill

How does a smart thermostat work?

A smart thermostat is connected or plugged into your Heating, Ventilation, and Air Conditioning (HVAC) system using a wired connection. This is then, managed by the thermostat control.

The smart thermostat is also connected to an internet connection. Hence, you must download first the smart thermostat app into your smartphone, computer, or laptop. With this, you can control the smart thermostat remotely or wherever you are.

Another way to control the thermostat is through the device interface on the wall. You can manage the temperature by turning it on or off through the main interface. As well, you can set the schedules from it.

Best Smart Thermostats 2019

We have reviewed some smart thermostats in the marketplace today. And among that tops in our list are the Nest Learning Thermostat (3rd Generation) and the Ecobee 4.

To contribute ideas about these smart thermostats, we would like to partake some details about them that we think could help you choose which one would best suit your home.

  1. Nest Learning Thermostat (3rd Generation)

Best Smart Thermostat 2019The Nest Learning Thermostat 3rd Generation is the best-selling smart thermostats in the market today. Thousands of people all over the globe have been using this smart device and the majority of them are satisfied with its performance.

This smart thermostat is proven and tested as a device that can really save energy. In fact, it is the first thermostat that has the Energy Star certification.

Also, some studies indicate that Nest Learning Thermostat can save an average of 15% on cooling bills and 10 to 12% on heating bills. What we like with this thermostat is that it is equipped with auto-schedule and no need for programming.

It can also alert you if there is something wrong with your HVAC system. Since it is a smart learning thermostat, it can check your energy history and updates you on your energy use.

Hence, you will know if you need to reduce your energy consumption. Another good thing about it is that it works with Alexa for voice control. Also, it has a Farsight feature that lights up to show you the time, weather, and temperature.

Get to know more the Nest Learning Thermostat 3rd Generation from the reviews of the satisfied customers.

“Yes, I’m another proud Nest concert and will never look back! It’s simply awesome for my gas heating and cooling forced air system here in Texas. The weather changes seasons inside of one day here during the winter months so having a Thermostat that switches between AC and furnace automatically is amazing to me.” – Joe Granger

“The new “Far-Sight” feature is awesome and can catch me at approximately 10 feet away even in the dark. When Nest detects any motion it will illuminate with what the current temperature is. This is how it can tell if you are home or not and can automatically place itself in “Away Mode” for energy savings. Being able to control everything from the application on my smartphone itself is so awesome (fan, cooling/heating mode, humidity level, away/home mode, set a schedule, history, etc.). Nest will remind you when you should change your air filters on your furnace because it can base it upon how many times it turns on and off. A significant drop in energy consumption can be seen on my gas bill after month 1. Due to this my father purchased the item as well and has no complaints thus far.                                                                                                                                                                                     – AL

  1. Ecobee 4

Ecobee is the first manufacturer of the smart thermostat way back in 2007. And now, they are releasing their new smart thermostat, the Ecobee 4.

What we like with this thermostat is that it is equipped with built-in Alexa for voice recognition. Hence, you can adjust the temperature using your voices. Besides, you can do many things such as reading news, set a timer, and many more.

Another good thing about this smart thermostat is it has a room sensor. It can manage and control the hot or cold areas in your house and adjust its temperature to make you comfortable.

Also, it can detect occupancy, in one instance, you are out, it can automatically manage the temperature, which can save you energy.

Here are some of the critiques of pleased customers:

“As far as thermostats go, it is outstanding. It has all the capabilities you could possibly want. Like you would expect, you can program modes (home, away, sleep), schedules (what time to trigger modes), and remote access using the app. It also seamlessly integrates with my other automation systems like SmartThings and IFTT. You can also fine-tune lots of little aspects, like the ability to run the fan for so many minutes every hour or how long to run the fan after the AC turns off to help circulate air.” – Tyron

“On top of that, Ecobee has been in the Smart-Stat space for a very long time – much longer than Nest. They have worked through many of the challenges and have perfected the installation and operation of their thermostats. Installation is well documented and easily performed – with wiring display in the stat itself as well as a test mode to validate your install. Sure, the advanced options can be intimidating, but they are easy to configure and give you greater flexibility for your equipment, location, and control needs.
My Ecobee(s) are rock solid and, aside from an occasional wifi loss (which only required a reconnect – which never impacted the A/C operation) they are an excellent product.” -Cowboy Up

  1. I am really no longer surprised that smart thermostats are now being produced due to the advancement of technology. I was actually anticipating it. These would really come in handy in my home as we spend a lot on electricity due to air conditioning and heater in my home.

    Most of the time these costs become high because we always forget to turn them off when we leave the house. We normally leave in the mornings and come back in the evenings with no one in the house but these things keep running and increasing my electric bill without anybody been around to put it off. 

    With fact that a smart thermostat can help in doing this makes it all more amazing. This I really have to try.

    1. Hello Jay. Thanks for your views about smart thermostats. They are actually true. Yes, you can try it and see how it can save energy, which would lessen your electric bill. Wishing you the best!

  2. Hi

    I heard about the smart thermostat and I really like your presentation. It has all the information for someone like me who did not know exactly how it works or the benefits of having one. 

    It is quite money saver ( I’m sorry I see dollars signs everywhere). What I potentially see is the possibility to take control of your energy consumption and spending. You are able to switch it on and off depending on your need. 

    Thanks for sharing!

    1. Hello Adyns. I’m glad you appreciate our article. Yes, it can manage the energy consumption in your house especially your HVAC system. This will lead to energy savings. Thanks for your comment. Wishing you the best!
