Copper-finned tube, non-condensing appliances are the foundation of Lochinvar's success. In 1993, Lochinvar introduced the Copper-Fin® II, the first horizontal chassis, copper-finned tube water heater to operate with fan-assisted combustion. Now, the Copper-Fin® II is even better. Along with high thermal efficiency, gasketless heat exchangers and multiple venting options we have added Lochinvar's exclusive Smart System™ control.
