What does an aquastat control?

Steam pressure
Oil burner ignition
Water temperature
Smoke detection

The correct answer is: Water temperature

An aquastat is a critical component in heating systems that regulates water temperature within a boiler or hydronic heating system. Its primary function is to monitor the temperature of water and ensure that it remains within a set range. When the water temperature drops below a predetermined level, the aquastat activates the heating source, such as a boiler, to raise the temperature. Conversely, when the desired temperature is reached, the aquastat will turn off the heating element to maintain efficiency and prevent overheating. This precision in temperature control is essential not only for comfort but also for the safe operation of the heating system, as excessive temperatures can lead to damaging conditions. Understanding this control mechanism is vital for anyone involved in the operation and maintenance of low-pressure boilers.
