August 24 began as an unseasonably cool day in New York City, which made for a fitting scene as the community gathered to discuss a range of heating-related topics at Wetstock 2019.

Erin Holohan Haskell, President of, began the event by addressing the sold-out crowd with attendees visiting from across the US. “We’re thrilled and very grateful to be among friends here today in this beautiful landmark building of the General Society of Mechanics and Tradesmen of the City of New York. We’re going to have a wonderful afternoon learning from one another, surrounded by all of this remarkable history.”

Throughout the afternoon, attendees gathered at different tables to discuss various topics including radiant heating and controls, geothermal, solar, indoor air quality, innovative construction, hiring and training, making steam heating more efficient, tricks of the trade, the future of our industry, and more.

Attendees also had the unique opportunity to tour Larry Weingarten’s recently donated antique water heater collection and see Gil Carlson’s original System Syzer (now the Carlson/Holohan Award for Industry Excellence).

“I could feel the past generations who built NYC all around me in that place. It was a feeling of pride to be in that building and around all of the great people present. It was awesome to see and catch up with everybody,” added John Ruhnke.

Erin Holohan Haskell noted, “At we have a saying we call A Century of Pride and it goes like this: ‘A hundred years from now, they will gaze upon my work and marvel at my skills, but never know my name. And that will be good enough for me.’

“Consider that as you gaze upon the steam pipes around the perimeter of the skylight up you share your knowledge with friends here today...and as you continue to leave your mark on this world.

“We thank you for all that you do and are so pleased to have you here with us today and in our community at”
