Lochinvar COPPER-FIN GAS FIRED WATER HEATERS
COMMERCIAL WATER HEATERS
The Copper-fin Atmospheric water heater features a simple design to deliver trouble-free installation, long-lasting durability, and prevention from lime scale buildup.
STANDARD FEATURES
Copper Finned Tube Heat Exchanger
The heart of the Copper-Fin water heater is its copper-finned tube heat exchanger. The gasketless copper tube heat exchanger] design reduces the risk of leaks or system failures that are common with] conventional water heaters.
- Built-In Draft Hood: With our built-in draft hood, the Copper-Fin water heater installs easily in applications where overhead space is limited and headroom\ restrictions exist.
- Loch-Heat™ Ceramic Tile: Our incredibly durable, Loch-Heat ceramic tile will not crack or split and provides the benefit of an overall water heater weight reduction of 25% over other refractory materials.
- A Better Idea: The Better Idea system combines the Copper-Fin water heater with a separate round] jacketed storage tank to provide a high performance water heating system.
- Serviceability: The water heater’s design allows for easy access to all major components for servicing. The heat exchanger is designed to slide out the front of the water heater for faster maintenance.
- ASME Temperature & Pressure Relief Valve: Factory installed.
- 3-year limited Heat Exchanger Warranty, 1-year parts warranty: See warranty for details..
