Hot Water Baseboard
The hot water baseboard heater is a zone equipment used to meet any remaining zone load not met by other equipment in the zone that have higher heating priority. The unit is connected to a hot water loop (demand side) with an inlet and outlet node.

This field specifies the heat transfer coefficient for the baseboard heater at design conditions. The UA factor is used in a Number of Transfer Units (NTU) calculation.
An estimate of the UA can be obtained from:
q = UA x (T water, avg - T air,avg)
Where:
q = heat transferred from water to the air (Watts)
Twater, avg = average water temperature
Tair, avg = average air temperature
