Is A Smart Wi-Fi Thermostat The Best Choice For Your Home?

There are massive benefits to making the switch to smart thermostats – they are convenient, they’ll help you save money with reduced electricity bills, plus they pay for themselves in just a few months. 

Traditional thermostats will only allow users to adjust a home’s temperature. As for a smart unit, it allows its user to set a schedule and let the device change the room’s temperature based on a set schedule. 

The most advanced thermostats take this one step further by learning their user’s preferences and they then set the temperature of the room based on previous uses. A smart thermostat can also show energy reports, be controlled remotely, as well as adjust its properties based on conditions outdoors. 

We know you’re curious about how the best smart Wi-Fi thermostat can help you save money. The reason why this small piece of gadget can bring so much savings is because it knows the exact time to run and switch off. Of course, that is the case if the thermostat is programmed correctly. A smart thermostat reduces any unnecessary cooling and heating going on. HVAC systems account for up to 50% of a home’s electricity bill. Any reduction in its usage will definitely bring massive savings on your utility bills. 

How Does Programmable Thermostat Save Money

With 50% of your utility bills spent on heating and cooling your home, installing a thermostat can save you lots of money. As you know, programmable thermostats let you program your heating and cooling schedule and once programmed, the basic thermostat takes care of your heating and cooling.

In other words, it switches on and switches up, down or off as required at the time you set it for. The more complex models reduce energy consumption by offering more flexibility to further reduce your utility bills.

There are thermostats you can access from office to change settings in case you won t return be able to go home at the programmed time. Some models even let you change the system settings to adapt to local weather or humidity levels from your laptop or desktop.

There are also some models which tell you how much energy you consume and analyze elements like local weather conditions, your building size and the amount of activity in it to enhance your energy consumption.

So regarding the amount of money the thermostat can save you, it depends on the unit as the more advanced its technology, the more you can save. Of course, even the basic programmable thermostats can help save as much as 15% of your energy bills while the more intricate ones can save you anywhere up to 20% and more.

The savings in fact override the amount spent for most programmable thermostats! For example, if you presently pay $2000 for your utilities, a 20% savings mean you save about $300-$400 which is more than the unit s price. So installing a programmable thermostat proves beneficial as it pays for itself in no time.

Features Of The Best Smart Wi-Fi Thermostats: 

It pays to know which features you want for your new smart thermostat as this will allow you to narrow down your choices and understand what you are investing your hard-earned cash in!

  • Smart Settings

  • If you spend lots of time at home, you can definitely choose the most basic thermostats that don’t require any programming. However, if you go out of your house every single day and you maintain a regular schedule, you could definitely make use of a more complex model.

    Opt for the smart thermostat that will let you set several different schedules for your work days as well as the weekend. Most units will let you set a maximum number of temperatures daily while others, especially the ones that are most advanced, won’t require any programming as they’ll simply “learn” your schedule. Very convenient, right?

    The main reason why most homeowners are trying to get their hands on smart thermostats is because of the cost savings and convenience they bring. You'll be able to program a smart thermostat to switch off while you’re away. An hour before you return, the thermostat will start cooling down or warming up your home. You won’t just get a comfortable environment, but you will save money as well!

    Because your new smart thermostat is Wi-Fi-enabled, you will be able to update the settings or temperature of your home on the go! Yes, you heard that right. With the device, there’s now one less thing that you need to remember as you walk out of your front door each day. This feature will also come in handy whenever you go away for a weekend trip and you want your home to be ready and cozy when you come back.

    Remote access can be useful as well if you’re installing a smart thermostat in your vacation home. Before your arrival, simply turn on the air conditioning or heater from your smartphone to make sure that the place is set when you get there. If you’re renting your home on VRBO or Airbnb, you most definitely need a smart Wi-Fi thermostat to ensure all renters are comfortable when they arrive. When they leave, you can also make sure that your space’s HVAC system is switched off. 

  • Energy Reporting 

  • A smart thermostat will let you monitor your energy consumption. It can even offer you a comprehensive report on the energy that you’re using at a given time as well as how much you have saved since you installed the device. 

    As for the most advanced units, they will inform you of the current condition of your home’s HVAC system. The reports we’re talking about can be accessed online or through an app on your mobile phone. In some cases, the reports will offer further recommendations like the best ways to configure the thermostat in order to reduce your electricity bills.   

  • Smart Home Integration 

  • As you may know by now, digital assistants are getting more and more common! Millions of Americans today are letting “Alexa” run their homes and Amazon has already sold millions of Echo devices. Google followed suit as well. They introduced Google Home devices to the market, and then Apple launched HomePod which brings Siri inside your home.

    If you’re currently using a smart home device, then you definitely need to get a thermostat that works seamlessly with the system that you’re using. Most thermostats integrate with Amazon Alexa, which is constantly getting upgrades. Years back, Alexa was capable of playing music, providing weather information, making to-do lists, and so much more. Now, it can let you control your home’s temperature as well. You'll also be able to use Alexa to find out your home’s current temperature, set a target temperature reading, and decrease or increase the temperature.

    Of course, you can only enjoy all these features if you make sure that your new smart thermostat is compatible with your smart home hub or home automation hub.

    Apart from Alexa, smart thermostats can also work with all other home automation hubs such as Apple HomeKit, SmartThings, and Wink. If you have a smart home system already, we can’t stress how important it is that you check your new thermostat’s compatibility with it if you want to make use of its advanced features.

  • Wireless Remote Sensors 

  • The newest smart thermostats have wireless remote sensors that address the one flaw of typical thermostats which is measuring only the temperature of the areas that they are located in. This is usually the reason why most of them are installed in “hot rooms” of homes. More often than not, homeowners need to deal with the temperature inconsistency and crank up their HVAC systems to reach the dead zones. You may be able to reach dead zones and get them to comfortable temperatures, but you’re wasting energy by doing so. 

    Wireless remote sensors, as mentioned earlier, resolve this issue. The sensors measure temperatures of several rooms, and they allow you to manage the temperature of any area. If you want to have a more consistent temperature regulation throughout your entire home, then you need your new thermostat to come with several wireless remote sensors. 

    How To Choose The Best Smart/Programmable Wi-Fi Thermostat?

    Smart thermostats have a common issue: the one that you get must be compatible with your existing HVAC system. HVAC systems vary with most consisting of one or two-stage systems. Typically, thermostats support only a single cooling system or heating with multiple stages. But, some can have three cooling and four heating functions. For instance, you have a system that has air conditioning, baseboard heat, and hot air system. In such case, you have one cool and two heat system.

    A common system nowadays is the central cooling and heating system. It can be gas, electric, 24V or oil. If you’re not sure what you have, then check your furnace. An electric system doesn’t have glass windows. As for a gas furnace, it usually has a small window, as well as a blue flame that’s invisible inside. 

    Another important consideration that you need to take into account is whether your system makes use of a “C-Wire.” This will determine how you’ll provide power to a thermostat. Most smart thermostats need a C-wire, unlike traditional ones. 

    There are ways for you to install a programmable thermostat without requiring a C-wire; however, it’ll take more effort from you during the installation process. You always have the option of hiring an electrician to perform the process for you.
