High Duty baseboard

Can any tell me how many feet of high duty baseboard can be placed on a normal 3/4 loop. I know it's about 67 feet for standard output tube and fin

High Duty Basebaord

I'm not familiar with that brand, but several manufacturers offer heavy duty or high output variants.  The length limit for a 3/4" circuit would depend on the flow, which would in turn depend on the ∆T for the loop.

Typically...

40,000 btu on 3/4" copper. So if normal baseboard is around 600 btu/ ft that is around 66/67Ft.

You could go more but your output will not be 600/ foot after the 67'.

Typically high output is 750/ ft. (ie.. Sterling Senior)

That puts you in the 53' range on 3/4" copper

Beware

of the disclaimer that  "this includes a 15% heating effect factor " ,. this is a fictitious number that should be subtracted , making 600 per foot actually 510 per .
