NH150-DV and NH199-DV tankless hydronic boilers from Noritz.
The NH150-DV and NH199-DV tankless hydronic boilers from Noritz are available for constant room temperature comfort for various heating choices, such as panel radiators, baseboard flooring, and radiant floor heating. Significantly smaller in size than conventional hydronic boilers, the direct-vent units appear similar to tankless water heaters and weigh only 66 lbs versus a conventional boiler at 300 lbs. Featuring a gas-consumption range of 55,500 Btu/h to 150,000 Btu/h for the NH150-DV and up to 199,900 Btu/h for the NH199-DV, the units are ideal for residential or light commercial applications. They also offer nine temperature settings (140 to 180 F) for hydronic heating applications. Each unit has a high-flow capacity of 14 gpm with a three-speed Grundfos Pumps circulator, providing multiple pump curves, rather than the one-pump curve of a typical single-speed pump. The units also include an outdoor reset control.

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.
