Want to trim your heating costs this winter? Learning how to effectively use your house’s thermostat can help you slash those utility bills.

Learning how to effectively use your house’s thermostat can help.

The average household spends roughly $2,000 a year on energy bills, according to Energy Star, an efficiency program managed by the Environmental Protection Agency and the Energy Department. Nearly one-third of that money goes to heating costs.

Though steps such as sealing air leaks and changing furnace filters can help you conserve energy, knowing how to wield your home’s thermostat is one of the best ways to clamp down on the costs of heating.

Here’s what you need to know about thermostats to stay warm this winter without overheating your budget.

Which is for you?

A manual thermostat is the old-fashioned variety that lets you adjust the temperature in your house by moving a needle or by pressing “up” and “down” buttons. These thermostats — which generally range from $15 to $35, HomeAdvisor.com reports — are common in older homes, and they may be sufficient for people who spend most of their time at home, says Stacey Higginbotham, an Austin-based home technology expert. But a simple thermostat can be replaced by a programmable or smart thermostat.   

A programmable thermostat is essentially a “set-it-and-forget-it” product that lets you control when your home’s heating or air-conditioning system turns on according to a preset schedule.

According to the EPA, proper use of a programmable thermostat helps the average household save about $180 a year in energy costs. For most homeowners, a programmable thermostat is worth the upfront investment, considering it only costs $20 to $150, HomeAdvisor says.

A smart thermostat offers even greater convenience. Typically, these devices enable you to adjust your home’s thermostat remotely from an app on your phone. Some can even detect when you’re away from your house by tracking your phone’s location.

“If you’re gone, [a smart thermostat] can set the temperature to an energy-saving ‘away’ setting. Then, when it detects you are back in your home, it will resume the regular temperature setting,” says Eric Blank, editor at the Smart Cave, a smart-home product review website.

But, smart thermostats —which cost, on average, $200 to $300 or more — aren’t right for everyone. “I think it depends on the homeowner’s habits,” Higginbotham says. “The best candidates for smart thermostats are people who leave their house often, since they can raise or lower their heating and cooling as need be.”

Naturally, smart thermostats are also better suited for homeowners who are tech-savvy, says Pascale Maslin, owner of Silver Spring-based Energy Efficiency Experts, an energy auditing company.

Blank agrees. “If you’re not a techie, it may end up being more trouble than it’s worth,” he says. “Even with the best products, there’s potential for a disconnect problem or a configuration problem. If you end up having to do a service call, the cost of that call will add another year-plus to your payback period.”

So, how can you tell if you’re ready to go smart? “I would say a decent litmus test for technological competence would be being able to set up your home’s wireless router,” Blank says. If you pass that test, you should be able to learn how to operate a smart thermostat without losing your mind, he says.

Maximize savings

No matter what type of thermostat you have, you should be adjusting the temperature before you sleep, Maslin says. Indeed, you can save as much as 10 percent a year on heating and cooling by adjusting your thermostat setting by seven to 10 degrees from its normal setting for eight hours a day, according to the Energy Department.

If your house has more than one heating or cooling zone, installing a separate thermostat for each system can help you save more money, because some rooms (such as the basement or attic) tend to require more heating or air conditioning than others.

Three to consider

Although there are many options, here are three products to help you pick the right one for your needs.

MANUAL: Though most non-programmable thermostats are created equal, Eric Murrell, author of At Home in the Future, a smart home and technology blog, recommends Honeywell’s Deluxe Digital Non-Programmable Thermostat ($25 at The Home Depot). The device is “a reliable option for those with only basic heating and cooling needs,” he says.

PROGRAMMABLE: Murrell likes Orbit’s Clear Comfort Programmable Thermostat ($40 at The Home Depot) because of its large controls and display.

SMART: “While Nest used to be the leader of the smart thermostat pack, other players in the market, like Ecobee and Honeywell, have definitely caught up,” says Murrell, who recommends the Ecobee4 Smart Thermostat ($199 at amazon.com). It has a built-in Amazon Alexa that lets you use voice commands to not only adjust the temperature but also play music, hear the news or set a timer. Plus, the Ecobee4 comes with a room monitor that can sense where you are in your home and adjust the temperature accordingly.
