Where in Tn,are hydronic classes

There were some Johnstone Supply branches across TN that had some hydronics training offerings. A bunch of them were owned by the same group out of Kentucky, and had nice training rooms.

Caleffi does online hybrid trainings if you have a wholesaler that is interested in getting a group together. Reach out to the Caleffi rep in your area here. They do trainings on all their different lines, constantly.
