It was peace, love and a harmony of ideas at this premiere event.

Jimi Hendrix, Janis Joplin and Jim Morrison didn't show up - because they're dead. And you had to be dead not to come away from "Wetstock" invigorated in the art of hydronic heating.

Some 200 hydronic heating aficionados gathered in Marlboro, Mass., on Sat., Nov. 23, to discuss their craft and their business. Most were contractors, but included among them was a sprinkling of wholesalers, reps and manufacturers. But they were all "wetheads," to use the term coined by Wetstock's sponsor.
