Lochinvar Introduces the Efficiency Pac Commercial Gas Water Heater
by Lochinvar

Lochinvar Corporation is proud to announce the introduction of the Efficiency Pac® Light Commercial Water Heater. Ideal for light commercial use, this high-efficiency, direct-vent commercial water heater is designed for people who depend on hot water to stay in business. The Efficiency Pac combines the thermal efficiency of Lochinvar's Efficiency+® light commercial water heater with a Lock-Temp storage tank. Working together, these Lochinvar products combine to make an extremely efficient system, eliminating high operating costs. And with the rock-solid reputation of Lochinvar, the Efficiency Pac will make constant replacements a thing of the past. Thermal efficiency is the most accurate measurement of real efficiency because it determines the exact amount of heat transferred into the water during operation of the heater. The Efficiency Pac boasts an 85% thermal efficiency rating, which means 85 cents out of every fuel dollar are used to create heat. The efficiency rating is outstanding considering most competitive models peak at 80%. The Lock-Temp storage tank utilizes the Lochinvar baffling system to deliver 80% of the tanks volume without a drop in temperature. Combined with the Efficiency+ water heater, this not only yields a higher first hour delivery, 264 gallons for the EPN 200-85, but also lowers operating costs and provides longer equipment life than traditional tank-type units. To maintain maximum reliability, the Efficiency Pac has an integrated water heater control that ensures safe burner operation and prevents nuisance flame failures. Also an internal diagnostic panel monitors flame performance and can quickly restart the ignition sequence automatically. The Efficiency Pac fights the lime/scale build-up that all but destroys the thermal conductivity of a typical water heater and sends energy bills through the roof (just a quarter-inch of scale increases fuel consumption by nearly 40%). With its high-velocity water flow and its solid copper tubing, the Efficiency Pac fights scale build-up, saving far more operating dollars than conventional water heaters. Thanks to its direct-vent capabilities, the Efficiency Pac can draw its combustion air directly from outdoors, eliminating airborne dirt particles or chemicals. The direct-vent feature also isolates the heater from uneven air pressures caused by large exhaust or ventilation fans often found in mechanical spaces. The unit's pre-mix burner ensures clean, quiet combustion in all atmospheric conditions. It's a feature that makes Efficiency Pac "environmentally friendly," with an extremely low NOx rating. Additionally, the burner is designed so that the combustion air fan is on the air inlet -- not the flue discharge -- to greatly extend fan life. The Efficiency Pac is efficient in size as well as performance, fitting easily where other heaters won't. The unit is also remarkably light because of its copper tube heat exchanger and other design breakthroughs. For example, the unit uses Loch-Heat® tile, similar to material found on the Space Shuttle, to reduce unit weight by 25% compared to conventional cast refractory materials. Lochinvar Corporation is a leading manufacturer of high-efficiency water heaters and boilers, ranging in capacity from small residential units to three-million-plus BTU models. Based in Nashville, Tenn., with facilities in Detroit, Mich., Tampa, Fla. and Dallas, Tex., Lochinvar stocks equipment at all locations.
