Velocity Boiler Works (Crown) 270002 TWZ Tankless Coil

As a seasoned technician, you know that keeping a hydronic system running at peak performance means addressing the boiler tankless coil before scaling compromises the entire Domestic Hot Water (DHW) output. The Velocity Boiler Works 270002 is a field-proven TWZ Tankless Coil replacement designed specifically for Crown and Velocity systems. When your customers start complaining about inconsistent water temperatures or a noticeable drop in flow, it is usually a sign that the internal heat exchanger surface has become fouled with mineral deposits. This unit restores that vital heat transfer efficiency without the footprint of an external storage tank.

This genuine Crown boiler part is precision-engineered for a low-pressure drop, ensuring that hot water delivery remains consistent even during simultaneous fixture use. The 270002 comes complete with the necessary coil gasket (PN 270001) to ensure a high-temperature, leak-free seal upon installation. Built for the rigors of residential and light commercial applications, its durable copper construction is optimized for rapid thermal conductivity, making it the standard choice for contractors performing routine maintenance or emergency hydronic boiler repairs.

Key Benefits for Contractors:

• Direct Fit Compatibility: Specifically engineered as a drop-in replacement for the Velocity TWZ series, reducing field-modification time.
• Integrated Sealing: Includes the circular 270001 gasket to maintain system pressure integrity and prevent boiler corrosion from external leaks.
• High GPM Recovery: Restores the on-demand production capacity found in original factory specifications for reliable domestic hot water.
• Thermal Efficiency: Optimized internal flow patterns minimize resistance, helping the boiler maintain its AFUE rating while satisfying DHW demand.

Common Questions:

• Is the gasket included in the box? Yes, this specific SKU includes the 270001 circular gasket required for a proper seal.
• Will this fit older Crown TWZ models? Yes, the 270002 is the designated replacement for Velocity and Crown TWZ series boilers designed for tankless coils.
• Can I use this to replace a scaled coil? Absolutely. Replacing a fouled coil is often more cost-effective than chemical descaling, as it guarantees the restoration of the original heat exchange rate.
