flow in fin tube baseboard heat

mdwdrw69

Does running more than 4gpm in a standard high output fin tube base have any effect on the maximum output
Or is the maximum achieved at 4 gpm and anything faster just stays capped at the maximum output

The only thing changing flow rate will do -- within reason, that is -- is change the delta T across the radiation. In principle, a smaller delta T, for a given input temperature, will give slightly higher output, since it is the average of the input and output temperatures which determine the output.

plus velocity wear and noise at high flow rates
