Macgregor Hall
Circulated Hot Water Radiator

Macgregor Hall is heated with circulated hot water and Fin Tube Radiation. Steam from the Central heating Plant is piped into the building where it is used to heat the circulated water. The water is then pumped around the building to heat the spaces.
Sensors located throughout the building monitor the room temperatures and report that information to an Energy Management Computer System also located in the basement. This information is transmitted to a Master Computer System in the Central Heating Plant where it is checked against a heating program dedicated to the Macgregor environment. The automatic valves respond to this program to maintain the spaces at Setpoint ( the equivalent of a Thermostat setting).
The Engineer operating the Heating Plant when necessary can override this program.
Along the outside wall of each room is a section of Fin-Tube Radiation. The radiation is behind a face board which has an opening at the bottom and two openings on it’s face. These openings provide for airflow over the heating pipes, and this design depends upon a clear path for air to naturally enter and exit the radiation area in order to heat the room. A Thermostat located in each room controls fans installed in the face board. If the room temperature falls below the setting on the thermostat the fans pull the cooler air from the floor area and force it across the hot fin-tube radiation and then blow this warm air into the space. The warm air rises displacing any cooler air, which then returns to the fan / fin-tube system to be re-heated.
There is no other individual control for a system like this. Any change to the flow of hot water through a single piece of radiation would have a significant effect on all the radiation on the same piping loop.
This system provides generally even space temperatures and automatically compensates for outside conditions.
