Thermostats are designed as manual, programmable or smart. All three work with air conditioning and a variety of gas, oil and electric furnaces.

At their very basic, thermostats don't have to be programmed at all. You simply press a button or move a dial in order to heat or cool and select the temperature you would like. This type of thermostat is perfect for people who are at home a lot and don't mind having to wait for the desired temperature to be reached.

Of course, there are far more complex models on the market that will fit around just about any schedule you have. Some will allow you to set the same program Monday to Friday with the option for something different at the weekends (perfect for people who work and spend time at home on the weekend). Others go even further, allowing you the option to have up to four different temperatures throughout a 24 hour period, and you can even have different programs each day of the week.

If you really want something special, think about a thermostat that will "learn" your schedule. The ecobee3, the Nest Learning Thermostat, and Honeywell's Lyric are three great examples of "smart" thermostats.

The more advanced models will even produce reports telling you how much energy you're using and how you can utilize your system better, a feature well worth the slightly higher investment.

The ecobee3 "smarter" wi-fi thermostat

Their website says it all: "Most thermostats are located in the hallway. Since ordinary thermostats only measure temperature in one location, the hallway is comfortable but other rooms are not. Not every room heats or cools the same. By measuring the temperature in the rooms that matter most, ecobee3 helps address hot and cold spots, keeping you comfortable. Most homes only need a few sensors, however if you're lucky enough to live in a Chateau, rest assured we support up to 32."

The Honeywell Lyric

Lyric was designed for crazy schedules and spur-of-the-moment activities. You can control Lyric from anywhere on your smartphone, or let it adapt to your life as you go. Lyric can save energy when you're away, and get the house warm when you're heading home. No more wasted energy when you're out for the night, and no more getting in from work to a cold house. It'll even let you know when the filter needs changing.
