Lochinvar Corp. has unveiled its new and improved Copper-Fin® line of gas-fired water heaters and boilers. Upgrades include a built-in combustible floor shield, a built-in low-profile draft hood, electronic intermittent ignition, and a two-stage firing control system for boilers. The redesigned Copper-Fin boiler features two-stage electronic temperature control, saving fuel by regulating boiler output to match system demand. The new Intermittent Ignition Device also reduces fuel costs by eliminating the need for a continuously burning pilot light. This feature is now standard equipment on both the Copper-Fin boiler and water heater (CW315-500). The Copper-Fin continues to feature 82% thermal efficiency. Lochinvar Corp. Circle 4.
