adding radiant loop - hot water coil?

hey guys-



I haven't been around for a bit.  Installed my own Smith G8 with Carlin EZ gas burner last year, and i've been basking in the heat since :-)



i'm thinking of adding a radiant zone to my house.  I have available BTUs.



What's the consensus, can i design it using a hot water coil?  Is that common practice?

    Here is what I got

    I have Everhot tank feeding hot water tank 2 hot water baseboard zones, eventually one will turn radiant. (at the time of picture I only have 1 hot water baseboard zone in)

    looks great man

    what size pump are you running?



    if i use the smith 'tankless coil', i can get 1.75gpm continuous feed from it.



    off the cuff, that would equate to about 17,000BTUs, of which i have in my boiler.



    If i were to change the firing, i could get 2.0gpm.  This would be enough to heat the two small rooms that i want to heat.  I'm not doing a radiant floor, i would be using Euro wall radiators. 



    I'm just wondering why i see lots of Everhot tanks, and i never see anybody using their tankless coils for radiant.  Is there a problem with that?
