Lochinvar 100140997 Copper Fin Atmospheric Water Heater with Pump 270000 Btu/hr Natural Gas Cwn Series

Product Description

The Lochinvar 100140997 is a 270,000 BTU/Hr copper fin atmospheric water heater designed for commercial and light industrial hot water applications. This unit is part of the Lochinvar CWN Series and comes equipped with an integrated pump and intermittent spark ignition for reliable, automatic startup. It runs on natural gas and is built to deliver consistent, high-volume hot water output in demanding environments such as hotels, schools, laundromats, multi-family housing, and commercial facilities where dependable hot water supply is critical every day. HVAC and plumbing professionals trust this series for its straightforward installation process and long-term reliability. The copper finned tube heat exchanger sits at the core of this water heater. Copper is a proven material in heat transfer applications. It conducts heat efficiently, resists corrosion, and naturally inhibits lime scale buildup, which is one of the most common causes of heat exchanger failure in hard-water regions. The gasketless copper tube heat exchanger design eliminates a frequent failure point found in conventional water heaters. Without gaskets to degrade over time, the risk of leaks and costly system failures is significantly reduced. This makes the 100140997 a dependable long-term investment for facilities that cannot afford downtime. The atmospheric venting design keeps installation simple. The 8-inch vent size accommodates standard commercial venting configurations. The 3/4-inch gas connection is compatible with typical commercial gas supply lines. The intermittent spark ignition system replaces a standing pilot, reducing gas waste and improving safety. Plumbers and mechanical contractors working on replacement or new-construction projects will find this unit easy to spec and install. The CWN Series is engineered for straightforward serviceability, which reduces labor costs over the life of the equipment.

• Copper finned tube heat exchanger resists lime scale buildup and corrosion for extended equipment life
