How much Slant fin?

[nporter]

How many feet of baseboard can one amass in one zone? I have a Tarm 30 with storage, 3/4" copper pipe, and a need to expand a zone that has 30' at this time and would like to add 20' to this existing zone. Is this a no no? (The space has grown recently and needs some of that good wood generated heat in this new space)


If this is not possible:

Is there a simple way to put a Y in an existing zone to establish a second zone?


Thanks,

3/4" = 67 feet of element max.

Is this the math for that result? 3/4" at 4 gpm rating and delta-T = 20 is 40,000 btu; baseboard is 500-600 btu/ft; 40,000/600 = 67 ft.

I suspect that the issue is temperature drop. The longer the loop, the cooler the water is by the time it reaches the last baseboard. If that's the one that keeps your wife's feet warm, it's not a pretty sight.

Any possibility to add another parallel zone?

We all are ruled by " All i got to do, is keep my wife warm, and life is good." If she ain't happy, you ain't happy! Sorry to high jack the thread.
