What is the primary role of an aquastat in a heating system?

The primary role of an aquastat in a heating system is to respond to water temperature changes. An aquastat is a temperature-sensitive device that regulates the operation of a boiler or a hot water system based on the water temperature. It measures the temperature of the water and activates or deactivates the system accordingly, ensuring that the water reaches and maintains the desired temperature for efficient heating.

When the water temperature falls below a set point, the aquastat will trigger the heating system to turn on, allowing the water to heat up. Conversely, when the desired temperature is reached, it signals the system to shut off, preventing overheating and conserving energy. This function is vital for maintaining comfort in heating applications and for protecting the system from potential damage caused by temperature extremes.

Understanding the role of an aquastat helps in diagnosing issues within a heating system and emphasizes the importance of temperature regulation for efficient operation.
