Baseboard Radiators

[trehugr]

Wondering if anyone uses Runtal Baseboard Radiators. They claim usable heat down to 140º. Might be a solution to my overtaxed main floor loop.

Any radiator can use lower temp water, they quote output using 180.

 

[Como]

40°C 0.75 72°F
45°C 0.88 81°F
50°C 1.00 90°F
55°C 1.13 99°F
60°C 1.25 108°F
65°C 1.39 117°F
70°C 1.51 126°F

This is from Myson, but the conversion factors are probably the same.

Centigrade, Multiplyer, Fahrenheit

I don't have baseboards, but a while back I ran across a reference to this product, which looked potentially promising:

I had not come across those, looks a bit clunky, there are several baseboard replacement products:

We use slant fin, and Haydon. Both have ratings for 180 degree water, but if you look deeper into the literature, as one would expect... higher temperatures bring higher btu output, lower temperatures lower btu output, and they're similar.
I imagine any fin tube will have similar properties

You can use lower baseboard water temps efficiently by adding more baseboard.
