One of Ferguson Enterprises' branches in Washington, D.C., worked with several manufacturers and its own resources to produce a promotional hydronics heating equipment jigsaw puzzle. The idea to create the puzzle came from Carl Anderson, hydronics manager, when he couldn't get hydronics pieces out of his mind while working on a puzzle with his children.

The puzzle shows the outline of a house, with parts from Taco and the rest of the sponsors, including Peerless Boilers, Riello, Slant/Fin and Amtrol, melded into a hydronics system inside the house. The puzzle's border is filled with facts about the hydronics industry and the names of children and grandchildren of the people involved in the project.

The puzzles were given away to attendees of training classes, as well as with purchases of participating hydronics equipment manufacturers. “I have customers that want them that don't buy hydronic heating equipment,” said Anderson in an e-mail to Dan Holohan. Anyone who finished the puzzle had to have it checked by a Ferguson or sponsor employee, and was entered into a drawing for a grand prize trip for two to Las Vegas. The drawing will be held in the fall. The first 100 that finished also received a free T-shirt.
