For this piece, she spoke with tech experts to learn whether a smart thermostat is worth the investment, and just how much money one could save you. 

 What is a smart thermostat? 

Some of you might be sitting there wondering what a smart thermostat is in the first place. Essentially, a smart thermostat is a piece of smart home tech for a more energy-efficient automated home. 

These Wi-Fi-enabled devices automatically adjust the temperature settings within the home by learning your daily routine and then creating heating and cooling schedules accordingly. They're easy to use, make your home more energy efficient, and can even be controlled from your smartphone.

How much money could you save on your energy bills?

So now we've established what they are, the big question remains - are smart thermostats worth it?  

In most cases, these devices will end up paying for themselves over time as they help you to reduce bills. 'By learning your heating and cooling habits, a smart thermostat can adjust your temperature settings to minimize energy usage, which can lead to significant savings over time - in some cases, up to 30% on your energy bill,' explains Adam Roper (opens in new tab), blogging expert in renewable energy, sustainability and off-grid living.

Google Nest (opens in new tab)estimated this would result in an average saving of $131 to $145 a year. However, it's important to note that the amount of money you save will depend on a few factors, including the type of smart thermostat you choose, the size of your home, and the climate you live in. 'For example, if you live in a warmer climate, you'll likely see greater savings because your air conditioner will run less often,' says James Calderon, tech expert, and Editor of Alrigh (opens in new tab). 

If you have a modern gas boiler, Adam Chapman, heating expert and founder of Heat Geek (opens in new tab), says you ought to look for a modulating smart thermostat if you're looking to save as much as possible on your gas bill. 'Most smart thermostats are just on/off, which means they send a 'fire' or 'don't fire' signal to the boiler,' he says. 'A modulating stat will instead tell a compatible boiler what flow temperature to fire to, which can help you to save more money.' 

If you purchase one of these modulating varieties, you should be aware that they need wiring in a different way, which is likely to come with added installation costs. 

How much does a smart thermostat cost?

We're sure none of you are likely to turn down an opportunity to cut your energy bills, especially in our unpredictable climate, but how much will a smart heating system like this cost you?

Like anything on the market, the cost of a smart thermostat varies hugely depending on how advanced the model is. For a good all-rounder with a reasonable price tag, we think Amazon's smart thermostat, available here on Amazon, (opens in new tab) is a fantastic choice. ENERGY STAR certified, and with DIY installation and voice-activated control from Alexa, it comes in at $59.99. 

The Google Nest was the pioneer of the smart thermostat world, so, understandably, their models have some pretty advanced functions. The Google Nest learning thermostat, also available at Amazon (opens in new tab), is top of the range option coming in at $249. There's no need to program this small little stat - with its auto-schedule software, it programs itself by learning from your habits.

If you're on a tighter budget, the Honeywell Lyric T5 Smart Thermostat, here on Amazon (opens in new tab), is another sound choice. 'One of the best things about the Honeywell Lyric T5 is that it's compatible with a variety of smart home devices and platforms, including Amazon Alexa, Google Home, Apple HomeKit, and more,' says James. 'That means you can control it with your voice, with your smartphone, or with a variety of other devices.' At $125, it's a great value option, although its design is a little less sleek. 

For the price you pay to purchase a smart thermostat, the chances are it will have paid for itself in a year's time (or two, tops!). Practically speaking, we think they're certainly worth the investment, and not only will they help you save money, but they'll benefit the planet, too.

Which smart thermostat should I buy? 

Before investing in a smart thermostat, it's important to do your research to find the best option for your home. The type of heating system you have, your current lifestyle, and the size of your home are all important factors to bear in mind.

'You should also consider which features of a smart thermostat are most important to you, such as ease of use, compatibility with your HVAC system, and cost,' says Adam R. 

We love the low price and sleek design of the Amazon smart thermostat, but the Nest is probably the most hi-tech and user-friendly option on the market.
