Nest E vs. Nest 3 Thermostat

If you’re looking to add a smart thermostat to your home for that added level of convenience, comfort, and savings, the Nest E and Nest 3 are some of the best options on the market.

A smart thermostat allows you to make the most of your heating and cooling system without wasting money or energy. With a smart thermostat you won’t have to choose between comfort and affordability, you can have both. Here we are going to discuss the similarities and differences between two of the most popular smart thermostats, the Nest E and Nest 3 thermostats.

First off, let’s discuss the difference between a “Smart” thermostat and a standard thermostat.

Nest E. Nest 3 ThermostatNest smart learning thermostats are made to be easy to use and simple to install. The Nest thermostat does all the hard work for you. The quick setup only requires you to answer a few questions and the Nest thermostat will be ready to learn and operate. If assistance is needed during installation, professional installation services are always an option.

After some time of getting to know you, Nest personalizes its settings according to your schedule. If you tell the system that every night you go to bed at 11PM and wake up at 7AM, it will adjust its settings accordingly to ensure optimal comfort and energy savings. The system will also learn when you’re away from home and automatically adjusts the temperature during that time to save energy. The thermostat also adjusts to correspond with the type of of system you have, whether it be dual pump, forced air, etc.

Adjust your temperature from anywhere!

One of the biggest selling points of a smart thermostat is that it gives you the ability to control your heating and cooling system remotely from anywhere in the world. The Nest system has built-in Wi-Fi which allows you to access the device’s settings and features on your smartphone, tablet, or PC. This way you’ll be able to adjust your home temperature and settings while you’re away, check your schedules, and view energy usage over a period of time. As a Nest user, you will also receive a monthly email which details your usage and explains how the changes you’ve made affect your bottom line.

Now, let’s take a side-by-side comparison of the two Nest smart thermostats.
