A two-stage furnace works by constantly operating at a low power setting, roughly 70% of full power, and switching over to full power when needed. This switch occurs when the room temperature fluctuates two degrees or more below the temperature set on the thermostat.

How does a zoned heating system work?
The basic component of a zoned heating system is a zone valve, which controls the flow of water in a hydronic heating system. Inside the valve, an actuator opens and closes the valve based on the thermostat setting for that zone.

How does 2 zone heat work?
To combat this, at least two zones are installed – one upstairs and one downstairs. As one zone reaches the desired temperature, the thermostat slows the flow of air to that zone, which forces more air to the other zone and creates more even temperatures throughout your home.
Can you have multiple zones with one furnace?
Yes, you can add zones to an existing HVAC system. To convert your existing HVAC system to a zone system, you must do these: Install a zone control panel. Upgrade your thermostats.
How does a multi zone furnace work?
A zoned HVAC system divides your home into multiple zones, each controlled by its own thermostat. This allows you to set each room to the ideal temperature for you, instead of having to heat or cool the entire home to just one temperature.
Do I need 2 thermostats for 2 zones?
Sometimes, central HVAC systems are broken up into multiple zones (through duplication of heat sources, or usage of dampers and ducts). Each of those circuits will require their own dedicated thermostat. If this is the case, we'd recommend a separate smart thermostat for each zone.
Is 2 zone heating worth it?
Lower monthly energy bills: Is dual-zone HVAC worth it?

What Is Zoned Heating?
A standard, non-zoned heating system controls the temperature of the entire house as a whole. A zoned heating system, in contrast, allows homeowners to control the temperature of each room or zone individually, thereby maximizing comfort and minimizing energy costs. A zoned system can be adjusted for numerous factors, including room usage, personal preferences, and environmental conditions. Zoned systems help homeowners use their heating systems more effectively by distributing heat where and when it is needed.
How does a zoned heating system work?
How Zoned Heating Works. The basic component of a zoned heating system is a zone valve, which controls the flow of water in a hydronic heating system. Inside the valve, an actuator opens and closes the valve based on the thermostat setting for that zone.
What are the benefits of a zoned home?
“The advantages of a properly zoned home include savings on heating costs, and greater control and comfort throughout the home ,” points out Daniel O’Brian, a technical expert from online retailer SupplyHouse.com. “If they are individually zoned, unoccupied or rarely used spaces do not have to be heated, and areas of the home that get colder than others can be adjusted directly for greater comfort. Furthermore, programmable thermostats can increase savings by dialing back heating usage when residents are out of the home or sleeping.”

O’Brian explains that a typical zoned heating system treats the main floor of a house as one heating zone and the upstairs bedroom area as a separate heating zone. This allows heat to be directed to the main floor during the daytime and to the upstairs bedrooms at night, allowing unoccupied areas of the home to cool down when vacant.
Can a thermostat be used to zone a home?
There are also a wide variety of thermostats available, including programmable versions, to control a zoned heating system. “Any thermostat can be used to zone a home, but not all thermostats are for the same application,” O’Brian notes. “Voltages, the heating/cooling system layout, and features on different thermostats can be geared more towards one or another application.”
