The challenge

Lochinvar, based in Lebanon, Tennessee, is an industry leader in the U.S. for condensing boilers and water heaters. The specialists were looking for a solution to increasing demand for progressively more powerful and yet compact condensing boilers. The problem: Since the boilers are also installed in retrofitting scenarios, they must fit through doors and narrow passages. The second problem: The solution needed to be found quickly, as a prototype was to be showcased at the ISH in Frankfurt which was three months later. This was just the right challenge for ebm-papst, who has been a close engineering partner to Lochinvar for years.

The first project for the new Power-Fin high-performance gas-fired boiler was a building complex in Las Vegas with 300,000 square meters of floor space. Three large-volume gas boilers were replaced with a total of 24 independent, high-performance gas-fired boilers. Controlling the heating line has been considerably improved, and the efficiency of the complete system has been improved by around twenty percent. And, of course, the compact Power-Fins fit without any issues through every standard doorway.
