What is the difference between a single-stage and a 2 stage thermostat?

A furnace with single-stage heating contains a fixed gas valve and a single-speed blower motor. These furnaces are either on and running at full capacity or off. A model with two-stage heating contains a two-stage gas valve and a variable-speed blower motor.

Can I use a single stage thermostat with a 2 stage cooling?

Can you use a single-state thermostat on a 2-stage furnace? What is this? Yes, you can use it on a 2-stage furnace with a caveat. 2-stage furnaces normally have control boards that can be adjusted to work with a single-stage or a 2-stage thermostat.

What is the difference between single stage and two stage thermostat?

Single-stage heating requires only a fixed gas valve and a single-speed blower motor. While these get the job done, they allow the furnace to run at only one speed. This kind of furnace is either on or off. Two-stage heating requires a two-stage gas valve and a variable-speed blower motor.

Do I need a 2 stage thermostat?

To sum it up: If you plan to keep your home at a constant temperature, you don't need a two-stage thermostat. If you want to vary the temperature of your home during the day or night, a programmable two-stage thermostat is the way to go.

What does a 2 stage thermostat do?

Two-stage heating means the furnace has two levels of heat output: high for cold winter days and low for milder days. Since the low setting is adequate to meet household heating demands 80% of the time, a two-stage unit runs for longer periods and provides more even heat distribution.

What is the Difference Between Single-Stage, Two-Stage, and Modulating Furnaces?

What kind of thermostat do I need for a 2 stage furnace?

Normally a two stage furnace would require a four or five wire thermostat, and the thermostat would control the call for heat, by mode and stage.

What is better a single stage or two stage furnace?

If your home contains two or more levels, a two-stage furnace will be able to warm it much more evenly than a single-stage furnace--and for less money. If you plan to stay in your home long-term and are suffering from high heating costs, you'll have the opportunity to reap the benefits of this updated furnace design.

What is a single stage thermostat?

A single stage heating or cooling system means your furnace or air conditioner has only one level of heat or cold output. Single stage thermostats are used to control single stage HVAC systems—thus, if you have a single stage heating and cooling system, your home needs a single stage thermostat.

Does a 2 stage furnace save money?

The two-stage furnace is more efficient than the one-stage because it doesn't release as much fuel into the heat exchanger when the home is only somewhat cold. If it's 5 to 10 degrees outside, a two-stage furnace will run in the partially-open position and only use 70% of the energy it normally would.

Can I use a 2 stage thermostat with a single stage furnace?

Yes, I meant to say any two stage furnace... Using a 2 stage thermostat will not harm the furnace. And because the control board is compatible with a single stage thermostat, the furnace will still operate both stages. The control board would, as you say, start the second stage after about 10 minutes.

Does a 2 stage furnace run all the time?

On average, a 2-stage furnace runs on high about 25% of the time. A 2-stage furnace runs for longer periods of time because it's running on the low setting BUT this type of operation provides a more even heat distribution so it reduces air fluctuations or cold spots in your house.

Why are 2 stage heating thermostats used on heat pumps?

Improved humidity control — A two-stage heat pump runs for longer cycles than a heat pump with a conventional one-stage compressor. This gives the system more time to remove humidity from your air. In fact, a two-stage system can remove nearly twice the humidity as a single-stage heat pump.

How do you install a 2 stage thermostat?

What is the most reliable furnace brand?

What is the advantage of a 2 stage furnace?

Two-stage furnaces are able to produce more even heat distribution by using two levels of heat output. This allows the furnace to use technology to determine what level of heat output is needed for the current situation. These settings would include high for extreme cold and low for milder days.

Does a 2 stage furnace use more electricity?

For two-stage designs, the DOE test procedure consistently shows a reduction in energy consumption by about 3% compared to single-stage furnaces at the same AFUE level. In contrast, the 2006 AHRAE test procedure shows almost no difference in the total energy consumption at the same efficiency level.

What is 2 stage cooling?

Two-stage cooling means the air conditioner or heat pump has a compressor with two levels of operation: high for hot summer days and low for milder days. Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and produces more even temperatures.

Is a 2 stage heat pump worth it?

Two-stage heat pumps are highly efficient: they consume less electricity at lower speeds and run for longer periods of time. Long run times circulate air throughout the home, eliminating the likelihood of hot and cold or humid and dry spots.

Does a 2 stage furnace use less gas?

Two-stage furnaces cost more to purchase and install than traditional models. But factoring in their 20-25 percent fuel efficiency advantage, and assuming a normal lifespan of about 20 years, the extra cost will be more than erased by the cumulative energy savings.

Is a variable speed furnace worth the extra money?

The best news … a variable speed furnace motor is 80–85% more efficient than a standard furnace motor. So, if you are going to upgrade from a 90% to a 96% efficient furnace make sure it has a variable speed furnace motor, and you could enjoy energy savings of up to $400 a year. Otherwise it's not worth the investment.

Will any thermostat work with any furnace?

Know Your Equipment & Your Wiring

Not all thermostats are compatible with existing HVAC systems, especially smart thermostats! Some thermostats work only with furnaces and air conditioners, for example. Others may be designed to monitor heat pumps or multiple-stage heating and cooling systems.

How do I know what type of thermostat to buy?
