What method do you use for sizing fin-tube baseboard?
That method do you use for sizing fin-tube baseboard? If you’re like many practitioners your sizing procedure probably goes something like this:
Estimate the design heating load of each room.
Assume there will be a 20 degree F drop around the baseboard circuit.
Subtract half of this 20 degree F drop, (10 degrees F) from the boiler outlet temperature to get the average temperature of the water in the circuit.
Look up the Btu/hour output per foot of baseboard element in the manufacturer’s literature.
Divide this heat output per foot into the design heating load of each room to get the necessary length of baseboard.
