What questions should I ask a plumber about Radiant heating?

I'm looking to get in floor hydronic radiant heating added to about 1500 sq. ft. across 2 floors of a house my wife and I are purchasing. We're fully replacing the floors so this seems like a good time.

There is currently a 250k Btu boiler to support radiant heat in the kitchen and also radiators in a side room. The house also has forced hot air for most rooms.

I'd like to install radiant heating but I'm unsure what questions to ask to make sure I get a good system setup and hopefully not get overcharged for things I don't need.

So any help with good questions or suggestions for system specs (like if I want a second pump on the second floor or whatnot) would be greatly appreciated. Thanks!

    Adding pics of the current system. The manifold is in a room about 20 ft from the boiler.

    This is the time for a full evaluation of the entire hydronic system. At first blush, the boiler seems oversized.

    I would give a couple of the major radiant manufacturers a call and ask for factory trained installers in your area. Uponor, Viega come to mind. This is one of your best chances to get it right. Things like floor loading, possible supplemental heat, floor coverings, home infiltration values, zoning, radiant heat loss, etc are all critical design criteria for a successful job.
