Lochinvar Introduces the Efficiency+ Residential Gas Boiler
1/1/1999
by Lochinvar

Lochinvar Corporation is proud to announce the introduction of the Efficiency+ residential gas boiler, combining energy-saving efficiency with unsurpassed performance and reliability. Ideal for residential and light commercial use, this high-efficiency, direct-vent boiler is the latest in Lochinvar's line of high- efficiency water heaters and boilers. 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 boiler. The Efficiency+ boasts an 84% thermal efficiency rating, which means 84 cents out of every fuel dollar are used to create heat. The efficiency rating is outstanding considering most competitive models peak at 80%. The Efficiency+ has a standard two-stage burner that saves fuel by closely matching output to system demand. And it allows a longer burner-on cycle to maximize operating efficiency. To maintain maximum reliability, the Efficiency+ has an integrated boiler 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. Thanks to its direct-vent capabilities, Efficiency+ can draw its combustion air directly from outdoors, eliminating airborne dirt particles or chemicals. The direct-vent feature also isolates the boiler 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. And it's a feature that makes Efficiency+ "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+ is efficient in size as well as performance, fitting easily where other boilers 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., Dallas, Tex., and Philadelphia, PA., Lochinvar stocks equipment at all locations. ###
