EVANSVILLE, Ind. - After spending thousands of dollars annually maintaining its leaky and antiquated boiler and radiant heat piping system, Karges Furniture decided replacement would be more cost efficient.

In fact, the 115-year-old furniture manufacturing building's piping had become so unreliable that the heating system was routinely shut down at night to prevent after-hours pipe breaks which could damage Karges' in-progress furniture pieces, which are all handmade works of art sold to interior designers and fine furniture retailers.
