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
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
