Two-Stage Heating

Two-stage heating means your furnace functions at two levels of heating output, depending on the temperature outside.

What is Two-Stage Heating?

Two-stage heating means your unit functions at two levels of heating output, depending on the temperature. Two-stage heating is an energy-saving feature found in many furnaces and heating units. It’s designed to work two ways: in colder weather, the two-stage heating system typically runs at high output, working hard to keep your home warm and comfortable; on milder days, the two-stage system can run at a lower output for greater efficiency. 

This two-part system maximizes your energy savings, as you won’t be paying to heat your home to an unnecessarily high temperature on milder days.

The difference between one-stage and two-stage heating systems

One-stage heating systems are the more traditional model. They run at a constant output, regardless of your home’s heating needs. This means that on mild days, you may be paying to heat your home more aggressively than needed, or to an unnecessarily high temperature. Two-stage heating systems are designed to address this issue, as they adjust their output depending on how close the current temperature is to the desired temperature.

Benefits of two-stage heating

There are several benefits that come with two-stage heating systems: 

• Increased comfort: As two-stage heaters function differently depending on the outdoor temperature, they can provide greater comfort throughout the year. 
• Lower energy bills: In certain situations, using two-stage heating can significantly reduce your energy bills, as you won’t be paying to heat your home to an unnecessarily high temperature. 
• Longer lifespan: Two-stage heating systems often experience less mechanical stress because they are able to operate at lower speeds, meaning you may not need to replace your unit for a longer time.  

Why you should consider a two-stage heating system

Two-stage heating is an excellent way to maximize efficiency and save money on your energy consumption. With two different stages of output, it’s designed to keep your home comfortable while minimizing costs in warmer months. If you’re looking for a more efficient and economical alternative for heating your home, two-stage heating could be the ideal choice for you.
