    check your pressure...if it is on the first floor, you'll
    be running at 10-12 pounds pressure...versus 1-2 on your steam system...ie, watch for leakage

    steve..

    Its done every day. BTU ratings differ from steam to water so make sure to size it correctly. What kind of forced water system do you have? Prep the tappings and clean it out REALLY good, install your bushings, plug(s),remove the upper plug and install your bleeder(this is always enjoyable) ect. then pressure test it before painting and putting it into service you'll be glad you did.

    taking a few steps back (more info)

    my foyer is cold! my i have 2 sets of doors leading outside from the foyer. both are 100 year old solid oak with large single pane 1/4" glass pannels. I weatherstripped and chalked but its still the coldest part of the house. I wouldnt consider replacing them though and im ok with the added cost of heating.

    my heating system is a 2 year old hydro-air with 3 zones. I was hoping to tap into the zone that heats the foyer area (and its surroundings) and add a radiator since the air register is too far from the door and too small to overcome the large heat loss. im also looking into installing staple up radiant tubes under the foyer from the basment - not sure yet.

    so, i guess my first question should have been:

    Can i connect an addtional heat source "in series" (to use an electical term since im no plumber) to the outlet of the radiator in my air handler in the basment (can do this myself = save $$) ? or should i make it a seperate zone (hire plumber - and run new thermostat wiring = more $$)?

    make sure rads are nippled top and bottom and are two pipe for hw circulation if there was a thermostatic trap, remove the guts add air vent at top of the rad [you will see a threaded plug be prepared to drill and tap the hole] re-pack rad valves good to go. also adding another zone is a good idea to handle a high heat loss area think about a freezestat if area under is uninsulated
