Baseboard heat...most BTU per foot

in Radiant Heating
I took some walls down and turned my kitchen, dining room and living room into a great room. I have baseboard heat on the walls I can get it on. The heat is OK, but it takes awhile to get it there. I have hi output on one of the walls, but the smaller Slant fin on two of the others. I do not want a kickspace unit, hate the noise. I’d like to replace the 20 or so feet of the smaller baseboard with a higher output baseboard. What base has the highest BTU per foot?
Thanks

    Smith Environmental's Heating Edge baseboards have high output.
    Sterling baseboards also have some high output units, including the Synergy, Sun Temp HO, Petite 9, and Heat Trim Plus lines of baseboard.
    There are probably others, too.

    Do you have a mod-con or a conventional boiler with fixed 180F supply water for spaceheating?

    It’s a peerless 160-180

    At 170F AWT the Smiths Heating Edge will put out 813 BTU's/ft if piped parallel.
    Your 20' run would put out 16,000 BTU's... enough to heat a small house :)

    The Sterling high output models mentioned by Brewbear have btu/hr/ft ratings 620 @ 160 degF and 800 @ 180 deg F. Their Classic HO a little lower. All of these basis 3/4" tube and nominal 1 GPM flow.
    Don't underestimate appearance. Dimensions are similar for all these models, but the enclosures vary. Some are better looking than others. You would probably want to match your existing HO or replace all with the look and heating output that suits.

    I suggest you review the test details Smith Environmental uses to rate the output of their Heating Edge. We tested it using the IBR/AHRI test procedure and the actual output did not come close to their published ratings. If you review their test method you should understand why.
    Using the IBR/AHRI test procedure our Slant/Fin HD-850 using H-1 element had higher outputs at ALL water temperatures...high or low. Slant/Fin rates all of our baseboard and finned tube products down to 110F water temperature.
    I cannot comment on Sterling other than stating I believe they use the IBR/AHRI test procedure to rate their products.
    I do work for Slant/Fin and certainly am biased. However, I believe we should all play on an even field and use the same standard to arrive at performance ratings. I assure you, the Heating Edge ratings are NOT based on the standard we use to rate baseboard...it is not apples to apples.
