Zone heat with baseboard heaters
If you have baseboard heaters, you probably know they supply heat to each room individually. If you have thermostats in separate rooms, you can use the concept of "zones" to heat certain areas of your home more than others, which saves up to 20% in energy use compared to heating both occupied and unoccupied areas.
Step by step:
- Turn it down or off. In rooms you tend not to use—such as guest bedrooms—or if you are leaving a room for a while, turn the baseboard heater down or off. Close the doors to these rooms to keep heat from leaking into them.
- Heat as needed. Turn the baseboard heaters on in rooms you are currently using or tend to use frequently throughout the day. If you are using a single room or a zone of your house that is fairly isolated, then close the door to keep the warm air inside.
- Monitor the dials and doors. Look through your house at the beginning and end of the day to make certain your heat use matches your room use. Close doors to rarely occupied rooms and areas.
In this context, a "zone" is an area that is somehow separated from other areas of your home by the presence of a wall, door, and/or a separate heating unit. You may have a "warm zone" and a "cool zone"—or multiple zones—in your home based on rooms you tend to use or not use. Good to know:
Keep the "cool zone" well above 32°F to avoid freezing pipes and other problems.
