Commissioning a HI Delta Raypak Boiler at Torrey Pines for a UCSD building. Had issues commissioning the boiler and was given Heasletts number for tech support. Called them and was put on the line with Keith. He was very helpful and knowledgeable about the boiler. Not only that, but he is a great person to talk with over the phone. I’m glad to have reliable tech support for Raypak boilers.
