Article Summary:
The Nest Learning Thermostat needs to know what kind of heating system you have so it can correctly control it. To help you identify what system you have, here’s a breakdown of how each system works.

During setup, the Nest Learning Thermostat will ask what type of system you have. The Nest Thermostat supports three kinds of heating systems:

FORCED AIR

IN-FLOOR RADIANT

RADIATORS

They’re similar to in-floor systems, since they don’t use vents or fans, but radiators aren’t installed under the floor.

Warm air comes out of vents or registers throughout your home.

Electric coils or hot water pipes under the floor heat your home.

Radiators are sealed metal containers filled with hot water, steam or electric coils.

If you’ve already set up your Nest Thermostat but you accidentally selected the wrong type of heat, you can adjust this setting in SETTINGS > EQUIPMENT > HEAT TYPE.

If you’re still not sure what type of heating system you have, contact a Nest Pro installer or our support team.
