Replacing Convection Heaters

Hey Everybody, I have a customer who would like to replace his convection heaters with long runs of baseboard on a monoflo system, are there any problems with this or any special concerns I should address?
Thanks, Bob Gagnon

    What exactly are convection heaters?
    And why does he want to change them?—NBC
  • Convection heaters are like radiators, made out of finned copper, in an enclosure to encourage convection. He wants to install baseboard because he doesn't like the radiator sized enclosures. From what I remember about monoflo systems, you had to space the tees supplying the radiators far enough apart to encourage the heated water to flow through the radiator, it's impossible to get to the piping, so I believe the long lengths of baseboard needed , would have too much resistance, and the hot water wouldn't flow through the baseboard, does anyone know if that is correct?

    Thanks, Bob Gagnon

    Yes @Bob Gagnon plumbing and heating, you’re correct. Unless you plan on repiping or installing baseboard of the same width with means of bleeding both ends, I wouldn’t advise it.

    with flow restrictive emitters I think two tees are required to add enough pressure drop in the common pipe. Fin tube, even TRVs can be piped in the branches.

    Chapter 11 in Siggys Modern Hydronic Heating has all the math required to design, about 16 steps required. Good info for troubleshooting also.

    How about runtal radiators? They look amazing when done right. Pricey... yeah... but best looking IMHO
