Burnham Boiler 8010812 Aquastat

The Burnham Boiler 8010812 Aquastat is a mission-critical SPST immersion-type controller designed for precise temperature regulation in hydronic heating systems. Engineered for high-reliability switching, this aquastat controller operates within a 40-180°F range, making it a standard replacement for various Burnham series residential boilers. The unit utilizes a liquid-filled sensing element to provide accurate thermal feedback to the burner circuit, ensuring the system maintains consistent water temperatures. For field technicians, the 8010812 offers a straightforward immersion well mounting configuration, facilitating rapid installation and calibration during service calls. Its robust internal switching mechanism is designed to handle the inductive loads common in HVAC boiler control circuits, providing a dependable solution for boiler high-limit protection or operating control. Maintaining this component is essential for optimizing fuel efficiency and preventing thermal overshoot in pressurized hydronic loops.

• Precise Thermal Control: Adjustable 40-180°F range allows for fine-tuning based on specific hydronic system requirements.
• Rugged SPST Switching: High-quality Single Pole Single Throw contact action ensures reliable circuit interruption.
• Universal Compatibility: Direct OEM replacement part designed specifically for integration with Burnham boiler parts and assemblies.
• Fast Thermal Response: The immersion sensing bulb detects temperature fluctuations rapidly to prevent short-cycling.

Is the 8010812 compatible with other boiler brands?
While this is a Burnham OEM part, it may function in other systems requiring a 40-180F SPST immersion control; however, checking the insertion depth and well size is critical for proper fitment.

What causes an aquastat to fail?
Common failure points include sensor bulb fatigue or pitted electrical contacts, which can lead to the burner refusing to fire or failing to shut off at the high limit.

Does this unit include the immersion well?
This model is typically the controller head and sensing element; it is recommended to inspect the existing immersion well for scale buildup before installation.
