Best Wifi Thermostat Reviews - The Ultimate Buying Guide
Buying Guides
First of all, you should know about basic information about choosing the right thermostat
Tip 1: Knowing about your heating and cooling system
- Compatibility :
In modern day homes nowadays, the most common central heating and cooling systems can be 24V, oil, gas, heat bump or electric. However heat pump systems are more efficient than other heating ones as they allow you to choose how much auxiliary heat to use. It’s said that a smart thermostat can be compatible with many types of HVAC system, but you don’t set up a thermostat and realize it doesn’t work, simply because that thermostat doesn’t not support your heating and cooling system. Remember, compatible or not, this thing needs to be confirmed 100%!
- C-wire or not :
Most kinds of thermostat do require C-wire to provide power for itself. Make sure your HVAC have C-wire or that thermostat has its own battery. You may find another wire to assume that function, but you cannot be sure about the stability of power in this case.
Tip 2: Understand your using habit
If your timetable is stable, for example, you go out to work every weekday at 8 am, come back home at 7 pm and usually spend most of your time on the weekends, a thermostat can learn your habit or support weekend program will be wonderful.
If your time at home is totally irregular, a thermostat knows when you’re away or you’re about to reach home will be so useful.
Tip 3: Consider your interests
You are a geek, aren’t you? Then I’m sure you won’t skip types of thermostat allowing its owner do things as much as possible. It’s usually not easy to use much and the price will be higher though.
In addition, if you do care about the look in your house, do not ignore thermostats with beautifully designed cover.
I love using and researching about wifi thermostat and one of my picks below will definitely give you which thermostat you really need.
