Sometimes, we thought about how much heating we are using? As we turn on the heater when it's cold and turn off if it feels too hot. But you didn't know how much heat you have been using?

Heating controls are basically the tools that stop all that guesswork. Old ones are simple dials and switches, but the new “smart” ones can connect to your Wi-Fi and let you change the temperature from your phone. Some even figure out your routine—like warming the house before you get back from work or switching off if nobody’s home.

It’s not just about thermostats either. You can get smart radiator valves or full heating packs that let you control each room differently. Handy if you don’t want to heat the whole house when you’re only using one room.
