could a fan be added to old baseboard

[Rugar]

Thinking of designing a fan for baseboards to gain more usable heat(delta)
Or just call me crazy and rip out the old baseboards and try another approach. Small old house. Would have difficulty running air vents.

Baseboards have worked for years but have got to have boiler hot to get much heat off them.

The fins are vertical. Think lots of computer fans placed below the baseboard.
Consider panel radiators.

We just sold an old (1860's) property, which my father purchased and renovated in 1971. It had been an enormous house, converted to apartments by some prior owner, and my father converted the first floor to office space (used by lawyers, realtors, engineering firm, over the years). Under what was the too-crowded kitchen, later the lobby, was a custom heat exchanger built by my father. It consisted of a large galvanized metal box (likely some large rectangular ductwork sections), in which he arranged a blower and several lengths of finned copper baseboard tubes. This hung between the joists in the basement ceiling, and exhausted thru a standard 4" x 10" register in the floor (or was it the toe-kick of a cabinet? can't remember now...). It worked very well for the 40 years we owned the joint, and is likely still working today. Might give you some ideas...

Jaga sells a 'dbe' for their radiators to boost output.

A few pc case fans and a 12v wall wart and a a snap switch you could hack a similar setup for baseboard. I've been thinking about doing it for a while but my house stays warm with low storage temps.
