Heat Exchanger & Domestic Hot Water Storage Tank - In the front is a commercial heat exchanger. Behind the commercial heat exchanger is a domestic hot water storage tank.
The entire system is monitored by direct digital controllers to control the water temperature, the boilers, the valve actuators, and the heat exchangers. It is important to monitor the temperature of any domestic water system. Temperatures above 130° F. should be avoided as it will scald people. This can result in legal issues so it is important this is controlled accurately. Direct Digital Control can offers alarms for this issue in case something goes wrong or something fails.
