I have a ground source system which is generating 105-110F ish water for my 3 floor zones.   I also have a baseboard radiant zone supplying a bedroom and a bathroom.   The house is 13 years old.   These were the baseboards used for a oil fired boiler.  So they are designed for much higher temps and did warm that room up.     I would like more BTUs to get into that bathroom.   Does anyone have any experience/suggestion as to what I can use to accomplish this with this temp of water?  I have seen low temp baseboards on the web, flat panel units, I even read about in line temp boosters ( did not make sense)

Thx
