What Is Two-stage Heating?

523136409Homeowners who are looking at indoor heating options often encounter terms like single stage heating and two-stage heating. These simply refer to the type of furnace that powers a home. While single stage heating and cooling systems are popular, a two-stage system is becoming the ideal option due to a number of reasons.

What is two-stage heating?

Two-stage heating refers to the type of HVAC system that comes with two levels of heat and cooling output. This means that they are more flexible because they can operate low for milder days and high when the temperatures drop during cold winter months.

Advantages of a two-stage heating system

The main advantage of a two-stage heating furnace is efficiency. This system usually operates at 65% of the furnace’s full capacity in most climates. When the temperatures drop to very low during the cold winter months, the second stage takes over to satisfy the additional heating requirements of the home.

A two-stage system is also quieter than other types since it does not operate at full capacity all of the time. This is because the furnace starts operation when the amount of cool or warm air required to cool or heat up  the home is lower. This type of system is also able to provide continuous heating and cooling without temperature fluctuations. These systems have efficient temperature regulation to ensure that no drastic temperature changes occur during the night. The way the system operates also lowers the moisture content in the air because of longer cooling cycles. This results to an even flow of dry air which prevents the growth of mold and mildew.

Finally, the system facilitates more efficient air filtration especially when it is running at low speed. Constant current of air passing through the air filters allow the filtration of more pollutants for cleaner indoor air.

Modern heating and cooling systems operate using multi-stage technology to save on heating and cooling costs. A more efficient operation, lower noise levels and improved air quality make two-stage heating a great option for any home.
