You can stay warm (or cool) in your home, use less energy, and save money by replacing your old thermostat with an easy to use learning (smart) thermostat. The operative word here is easy.
With a little training from you, a smart thermostat will learn your household’s temperature preferences, adjust to changes in your schedules, and suggest settings to save energy.
For instance, during the winter a smart thermostat will learn what time to turn your furnace down at night while your household is sleeping. On a hot day, a smart thermostat will learn when to turn on your air conditioning so that your home cools down before your kids get home from school or you arrive home from work. If you sign up for an account and download the app, you can control your thermostat using your smartphone and get detailed information about your home heating and cooling energy use.
A smart thermostat is likely to cost you between $150-$250, plus sales tax and possibly shipping if you buy it online. You may be able to install it yourself or with the help of a friend, but if not, hiring an installer will add to the cost. Most manufacturers claim that a smart thermostat could reduce your home heating and cooling energy use by at least 10-15% and that the thermostat will pay for itself in energy savings in two years or less.
There are probably 100 million thermostats hanging out in hallways across the United States. Imagine if every household had a smart thermostat. We could be comfortable in our homes, save some money, and most importantly decrease our reliance on burning fossil fuels to heat and cool our homes. When millions of people make even a small change, it can really add up to make a significant positive impact.
That all sounds wonderful so smart thermostats should be flying off store shelves, right?
I am highly motivated to curtail my energy use and yet it took me five years to decide to buy a smart thermostat because I was evaluating the purchase using outdated cost/benefit thinking.
Is a Smart Thermostat a Good Investment?
I have been eyeing smart thermostats since 2012 when I wrote about them in the post Use Your Thermostat to Save Energy and Money. At that time, I did the math and decided that replacing our old thermostat with a smart thermostat did not pencil out, meaning it did not seem like a good investment.
My spouse and I both work out of our home office so since we are home during the workday we use energy all day. However, we live in a temperate climate where the average winter temperature during the day is in the 50s and we do not have air conditioning. If we managed to save 10% a year on our natural gas bill, I estimated it would take at least four years or more for the energy savings to equal the cost of the smart thermostat.
So, what changed my mind?
First, I had to admit to myself that I was never going to learn how to use our existing programmable thermostat and that manually turning it on and off and adjusting the temperature when I thought about it was not an energy saving practice.
Once or twice during the ten years, we have lived in our current home, I opened the thermostat cover and looked inside with the intent of learning how to program it. The inner workings seemed complicated and difficult to use. I sighed and closed the cover feeling defeated. I know I could have tried to find the instruction guide online, but I never did.
Then there was the argument that our current thermostat was operational so it would be wasteful to get rid of it. Eventually, I realized that using more natural gas than we need to is much more wasteful especially considering that extracting, processing, and burning fossil fuels is harming people and the planet. We need to get off burning fossil fuels sooner rather than later and decreasing our own use is a step in the right direction.
The seemingly long payback period made me hesitant to spend $200 on a new thermostat. My only excuse for that holding me back is that I spent a couple of decades working in corporate America where every product purchase was evaluated based on how long it would take to pay for itself in either sales revenue or cost savings. Every decision was made with an eye on the financial bottom line.
My narrow thinking kept me from buying a smart thermostat until near the end of last year when I was researching and then writing about why you should learn to read your natural gas and electricity bills. My purpose was to empower readers to understand their own energy use and be responsible for decreasing their fossil fuel use. While I was editing my posts, I realized that I could and should do more than I was doing to reduce our household energy use by purchasing a smart thermostat.
Smart Thermostat Installation
Fortunately, my spouse agreed that we should move the dial forward on our goal to reduce our home energy use by purchasing a smart thermostat.
Of course, there are many different makes and models of smart thermostats on the market in a variety of price ranges. We opted for a Nest Thermostat E for $169 because it has a cool looking design and seemed easy to install and to use (it was and it is).
The picture at the top of the post shows what comes in the box accompanied by an easy to follow instruction guide. My spouse installed the new thermostat, however, even though I am not mechanically inclined I think I could have done it.
An optional rectangular piece of plastic comes in the box so you can cover up the outline and screw holes left on your wall from your old thermostat. My spouse is very handy, so we decided to spackle and paint over the wall.
Sure, replacing our old thermostat with a smarter version is a small change but imagine if everyone did it. If we want to have a habitable planet to live on in the future, we had better expand our vision of what constitutes a good investment.
