Finalist in Plumbing and Water Management in Consulting-Specifying Engineer's 2011 Product of the Year competition
The Rheem-Ruud Spiderfire line of condensing-type commercial water heaters offers a wide range of Btu inputs with thermal efficiencies from 92% to 95%. The 350,000-Btu-input unit can deliver 460 gal of water/hr at a 100 F rise. All models are equipped with a 100-gal storage tank and can operate on either natural gas or liquid propane. They can be installed as a single-pipe, power-vented product, or as a two-pipe, power direct-vented product if negative air pressure or indoor air quality is a concern. The tubes inside the heater’s flue system are coated with porcelain enamel to resist corrosion.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
