Lotta new schools around here. Chillers & boilers. So maybe that's how the big boiler makers last. Or churches. We have a new 2M Fulton Pulse and a bunch of Carrier splits with air handlers in our renovated building.
In a big city, there's often district heat. Indy has one of the largest in the country. Most older buildings don't have boilers and get their steam from the district plant. About all new buildings in reach of their lines get their steam and chilled water from them. Many older buildings that lose chillers also tap into the lines.
