Smart Thermostat Buying Guide

How to choose the best smart thermostat for your home? There are a number of factors you will need to consider to choose the one that fits your need.

  • Ease of use and installation 

It’s always better to buy a smart thermostat you find easy to use and set up. No point in investing in a unit where you need to resort to the manual each time you have to change the settings.

Regarding its installation, most thermostats are easily installed just by attaching your heating or cooling system with two low-voltage wires. 

Preferably install the thermostat on an interior wall away from vents and other heat and draft sources which may affect the temperature readings. However, it’s better to call the professionals if you plan to do more than a simple replacement.

  • Compatibility

You have to choose a thermostat which relates to the type of heating or cooling it works with. While single and two-stage are the two most common options, you also have three-stage support for heating purposes. This means that multiple stage furnaces have more than a level of heat output for additional efficiency and operation.

There’s usually one heating and cooling system to work with multiple stages, but some thermostat models work with as many as 4 heat and 3 cool functions. Some models with the main heating source which doesn’t support two-stage heating let you set an auxiliary heat source like a second stage.

This means if your system comprises air conditioning, a hot air system and baseboard heat, then it’s a ‘two heat and one cool’ system where the baseboard may be the first stage and the hot air system, the second stage. As backup heat is considered to be an additional heat source, you will need a thermostat supporting three heat sources and one cool in the above mentioned case.

  • Programming requirements

You need to choose your thermostat based on your thermostat needs, which are best evaluated based on your living situation like the regularity of your schedule, your climate and if you are regularly out of the home.

Smart thermostats needn’t be programmed for basic needs; you just have to press a heat or cool button and select your desired temperature. This is best for those who are home most of the time and who don’t mind waiting to reach the desired temperature.

Then there are complex models befitting any schedule you may have. Some let you set the same program through the week with an option for something different at weekends, and others even let you set four different temperatures throughout a day or different programs for each day of the week.

  • Energy-saving capacity

Practically all programmable thermostats today emphasize saving energy, mainly because they know your schedule. There are more advanced models which report how much energy you use and how you can use your system better. While this additional feature may cost some money, it is worth investing in.

  • Remote access 

Smart thermostats should preferably be wireless as they provide you with more freedom to adjust your HVAC when not at home. However, if this is the case, you need a Wi-Fi connection to install the thermostat and when you want to connect to and change system settings.

Additional Features to look out for

Different smart thermostat models have different features. Take a look at the various features available so that you know what to look out for a while choosing your thermostat.

  • Auto changeover switch

These thermostats automatically switch between heating and cooling and are a handy feature on warm days and cooler nights.

  • Adjustable cycle

An adjustable cycle helps as it prevents frequent on-off cycling for heating and cooling systems. With an advanced recovery setting, it’s possible to start heating or cooling anytime required so that your home is at a preferred temperature when you reach it.

  • Intuitive controls and bold prompts

It’s possible to avoid energy-wasting mistakes with its intuitive controls and large temperature and time readouts. For example, a bold ‘hold’ prompt reminds you that you are overriding the energy-saving mode for added comfort.

The touch screens of most models today replace the older version buttons and knobs. Programming and reading the display in the dark is made easy with the thermostat’s large backlit display. You are also informed of an activated heating or air-conditioning system through a clear system-status display.

  • Reminder

Smart programmable thermostats come with convenient additional features like a reminder for changing the AC or furnace filter based on elapsed time, and a memory-saving feature where all programs made are saved in case of a power outage.

Types of Thermostats

Thermostats are no longer only rounded; they now have brighter displays with exact settings to ensure optimal heating and cooling pleasure. The programmable versions come in two main types; those with and without remote access.

Thermostats with remote access let you control your thermostat remotely using your iPhone, Android or Windows Smartphone or computer. They have numerous sensors monitoring the different temperatures in different parts of the house and can even tell and make adjustments in occupied rooms. There are also some apps which can be used with these thermostats to collate your energy usage data to customize your heating and cooling schedule.

Its benefit is that it’s energy-efficient, convenient and offers better control of your HVAC system for reduced carbon footprint and energy bills. However, they are a bit expensive, and not all of them work with your home’s HVAC system.

Thermostats which don’t offer remote access have to be manually set along with your HVAC unit’s heating and cooling cycle. Most of these thermostats are programmable with a digital interface called digital programmable thermostats and offer an option of automatically scheduling your house’s temperature based on time.

These thermostats are cost-effective and offer various temperature points to set for different days of the week. However, they are not as accurate or site-specific as thermostats with multiple sensors.

How does a smart 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 the office to change settings in case you won’t return and 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 on 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 smart thermostat proves beneficial as it pays for itself in no time.
