Burnham Boiler Safety Controls & Aquastats

Burnham Boiler Safety Controls & Aquastats: OEM Precision for Hydronic Systems

Burnham has spent well over a century earning its place as one of the most trusted names in residential and commercial heating. Boiler safety controls and aquastats are among the most critical components in any hydronic heating system — and when those components carry the Burnham name, they are engineered specifically to work in harmony with the boilers Burnham builds. Browse the full selection of Boiler Safety Controls & Aquastats to find the right fit for your system.

What Aquastats and Safety Controls Actually Do

An aquastat is the temperature-sensing brain of a hot water boiler. It continuously monitors boiler water temperature and either energizes or de-energizes burners and circulator pumps based on precise setpoint thresholds. A high-limit aquastat shuts the burner down if water temperature exceeds a safe maximum, while a low-limit or operating aquastat maintains the minimum temperature needed for efficient heat delivery. Without a properly functioning aquastat, a boiler has no protection against dangerous overheating — making these controls every bit as important as the heat exchanger itself.

Burnham's Approach to Safety Controls

Burnham offers aquastat controls engineered as direct OEM replacements for their hydronic boiler systems. A standout example is the Burnham 8010801 — a factory-calibrated 150°F aquastat designed as a guaranteed-fit replacement for compatible Burnham hydronic boilers, requiring no modifications at installation. Because it is a true OEM component, technicians can count on exact fit, correct setpoint calibration, and reliable high-limit protection right out of the box.

For boilers equipped with Burnham's IQ Control System, the brand offers the 102717-01 Aquastat IQ Option Card Kit — an expansion module that adds a second, adjustable automatic-reset high temperature limit to the boiler. The kit includes a temperature sensor, an aquastat option card, a dual sensor, a sensor clip, and a thermowell, and installs by slotting directly into the boiler's IQ Option Panel. This modular approach makes it straightforward to add a redundant layer of overheat protection to models such as the Burnham ES2, ESC, and Series 3 hot water boilers — particularly useful for low-temperature applications like in-floor radiant zones or systems where radiators are located within living spaces.
