Burnham Boiler 8010801 Aquastat

The Burnham Boiler 8010801 Aquastat is a high-limit immersion controller engineered for precision temperature regulation in hydronic heating systems. Calibrated specifically for a 150°F temperature setpoint, this OEM component is a critical safety and efficiency device for Burnham Alliance water heaters and compatible boiler configurations. It functions as a single-pole, single-throw (SPST) switch that breaks the circuit on temperature rise, preventing overheating by accurately sensing water temperature within the vessel. Designed for 120 VAC, 60 Hz applications, the 8010801 ensures consistent thermal cycling and optimal system performance. Professionals typically utilize this aquastat controller in Alliance AL-26, AL-41, PAL-026, and PAL-041 models to maintain a steady thermal supply. Its durable construction is intended for long-term installation in demanding HVACR environments where reliable aquastat temperature control is non-negotiable for system longevity and contractor-grade reliability.

• Precise 150°F Thermal Regulation: Maintains a fixed setpoint to ensure consistent heat delivery and energy efficiency in hydronic systems.
• OEM Compatibility: Specifically designed as a direct replacement part for Burnham Alliance water heaters (AL and PAL series).
• Standard Electrical Integration: Operates on 120V line voltage with an 8A rating, making it compatible with most residential and light commercial boiler controls.
• Robust Immersion Sensing: Features an accurate sensing bulb for immediate response to liquid temperature changes, preventing thermal overshoot.

Is the adjustment knob included with this part?
No, this specific assembly (8010801) typically does not include the plastic adjustment knob; technicians should retain the original knob from the existing unit during replacement.

What is the primary function of this aquastat in a boiler system?
The 8010801 acts as a limit control that cuts power to the burner or circulator once the 150°F threshold is reached, protecting the system from excessive temperatures.

Can this be used as a universal replacement for other 150F aquastats?
While it shares specifications with some Honeywell L4006 series controls, it is specifically configured for Burnham application; verify the bulb dimensions and mounting bracket compatibility before field substitution.
