Utica-Dunkirk 43360408 Coil Kit

When you're servicing an Empire oil-fired heating system, a fouled or leaking domestic hot water coil is a non-negotiable fix. The Utica-Dunkirk 43360408 Tankless Coil Kit is the direct OEM replacement engineered to restore peak thermal transfer and domestic hot water performance. Rated for a flow rate of 3.7 GPM with a maximum working pressure of 150 psi, this high-efficiency copper tankless coil ensures a steady supply of hot water without the recovery lag of a standing tank.

This kit is purpose-built for technicians working on Empire Water 2 and EV models, providing a precise mechanical fit that eliminates the risks of "universal" alternatives. Constructed from heavy-duty copper for superior conductivity and resistance to mineral buildup, the assembly includes the coil gasket and necessary hardware to ensure a pressurized, leak-free seal. For contractors, the 43360408 part number is the standard for maintaining Utica-Dunkirk boiler integrity and ensuring the hydronic system maintains its domestic water temperature setpoints effectively.

Is the gasket included with the 43360408 kit?
Yes, this is a complete tankless coil replacement kit that includes the essential gasket required for a watertight installation.

What causes a drop in hot water temperature in Empire boilers?
Often, calcium and scale buildup inside the 3.7 GPM coil or a failed tempering valve reduces heat transfer. Replacing the aged coil with this OEM 43360408 unit restores the system's ability to reach desired DHW temperatures.

Will this fit the Empire Water 2 series?
Yes, this specific Utica-Dunkirk coil is the designated replacement for Empire Water 2 and EV models, ensuring exact bolt-hole alignment and flange sizing.
