Low temperature fin tube

Charlie from wmass

If by work you mean transfer heat to the room then yes. Lots of reset systems on baseboard in mass. just need to match the heat curve to the heat load is all.

Low temperature fin tube

Questions about the low temperature ratings of fin tube bb. What are your thoughts on the bb when the temperature is really low during reset? I am figuring 260 btu/ft @ 130 supply water temperature. This temperature will meet the heat loss requirements at design. My question is how well will the bb work during really low supply water temperatures in reset? Has anyone installed such a system? My concern is that when the bb is receiving low water temperatures below the 130 design will the bb work?

Thanks,

Marc

Clarification

My concern is when the delivery temperature is low (100 degrees) or less, will this still heat the space? I know it will work at 130 degrees. I would think that the but/ft will drop off alot and then the fin-tube would lose it's ability to distribute the heat.

Thanks,

Marc

I do it all the time

I program the base temp of bbd curves at 100. If the water temp is high enough to make the bbd warmer than the surrounding air, then heat transfer will take place.

I've got one house where the garage slab, basement slab, 1st floor plated tube, and the 2nd floor fintube bbd all run at 120F.

Key is "over size" the BB >> I run 130-140° at DDT-9° and 90 - 120° in the 25-40° >> heats the home effortlessly

Mark,...

In the past we have used: http://www.hawkstoneindustries.com/html/htgedge.html

and other baseboard at temps as low as 90' as an add on in radiant systems as well as multiple times in children’s nurseries and school common areas because of the concern of scalding at higher temps. At higher supply temps the heating edge output is phenomenal! You can considerably downsize as another advantage as a design consideration.

In one installation we have about 16 feet of heating edge in a 15 x 18 room, three outside walls running at about 100' supply temp, it heats the room in about 15 min, on 0 degree days and is the most comfortable room in this installation full of rooms with other cheaper baseboard. It far outperforms conventional perimeter heating and is very durable much more so than any conventional baseboard.
Unfortunately many supply houses don’t stock it, but many can order it quickly enough.

Make certain that the boiler "brain" or the control system has a "minimum temperature" function. Most, but not all do.

Optimize the reset curve for "normal" weather and "typical" operation by the user. If you then find a problem not enough heat in quite moderate weather you'll then use the "minimum temperature" function to say, "Hey--my emitters need at least this temperature to be effective." Without the "minimum temperature" function you [could] be forced to use a reset curve that's far from ideal.
