Adding radiant heat to existing hot water radiator system

Yep no problem with access, I have a full unfinished basement with good views of all the pipes.

How do the 'taps have to be plummed' to be proper for this type of system?
Currently the 'dead end' pipes are capped and consist of one inflow and one return to the main inflow and return which eventually flow back to the boiler. All the radiators run off the same inflow and return pipes, they just branch off where they are needed.
Will the radiant flow still work? How can the radiant system get water without all the water flowing through all the radiators? I suppose it can because it uses a much lower temp., right?

    Adding radiant heat to existing hot water radiator system

    I have a hot water radiator heating system in my home. In my kitchen, the radiator was removed and pipes capped.
    Can I use the 'dead end' radiator pipes to create radiant floor heat in the kitchen (during renovation), or do I have to run the hot water from the boiler?
    It it is possible, what sort of mixing valves etc. might I need?
    Can I have the radiant floor heat on a different zone than the radiator heat in the rest of the house?
    I've yet to contact a pro regarding this as I am currently drawing up the new kitchen and I was wondering if I need to make space for a radiator!

    Paddy, It can be done

    espceially if you can get under the floor.

    Yes, you can use the taps if properly plumbed.

    Yes, you can run new pipes from the boiler. I would only do that if the first yes fails.

    A manual three way mixing valve is a beautifull thing properly plumbed.

    Zoning is an easy opption with an injector pump and a relay.

    If you add a well designed and installed radiant floor in the new kitchen, you can discard the foot print of the radiator. The new kitchen will be the favorite room in the house. The quadrapeds WILL find the warm spots.

    I needed to sleep

    Which is what happens at my age.

    I am off to work, but you can check out Norm Harvey's PDF drawing on the, "Remove hot water baseboard in a single room" thread. Norm posted @ 6:04 on 11/10/08

    Will check back later.
