Connecting New Boilers to Old Pipes - Heating Help

For commercial buildings with a kitchen, the discharge hot water temperature to the building should be around 140°F. Many facilities are using this temperature now to kill the Legionella inside the pipes. To raise the incoming water temperature from the ground temperature to 140°F, the boiler water has to be higher than 140°F.
