Slant/Fin Corp. recently released its new Hydronic Explorer heat-loss calculator and boiler-based specifier. The CD is free to heating contractors as a business tool to help them quickly and accurately size heating jobs and specify boilers and baseboard.

"The Hydronic Explorer is one of the coolest tools I've ever seen," said Dan Holohan, Wet Head guru and PM columnist.
