Burnham 80160452 3/4" Immersion Well Assembly for Boiler Aquastat Control

The Burnham 80160452 is a genuine OEM replacement immersion well assembly designed for use with aquastat temperature controllers in Burnham V8H series residential water and steam boilers. This copper well assembly is manufactured by Honeywell (model 123871A) and provides a protective housing for aquastat sensing bulbs while allowing accurate temperature measurement of the boiler water.

Key Features:

• Copper construction for excellent heat transfer and corrosion resistance
• 3/4" NPT male threaded spud for secure installation
• 3" insertion length reaches into the boiler for accurate temperature sensing
• 3" insulation depth accommodates boiler jacket insulation
• 3/8" internal diameter shell accepts standard aquastat sensing bulbs (3/8" x 3")
• Protects sensing bulb from mechanical damage and chemical interaction
• Allows controller removal for testing or replacement without draining the system

This immersion well is compatible with Burnham UR and WR series boilers and works with Honeywell aquastat controllers. The threaded NPT connection provides a reliable, leak-free seal superior to packing nut installations. Professional installation by a licensed HVAC technician is required for all boiler components.
