can vary based on your heat loss Adam. You need to start with a room heat loss and see how many BTUs you need per square feet. That being said you will want to supply ROUGHLY about 140 deg. supply & 120 deg. return.
Don't go above 85 deg.surface temp. even if you have to add some supplimentery heat.
If your doing this type of heat for the first time make sure of all the details or they will come back and bite you in the you know where.

    I was just wondering what the average supply and return tempurature for injoist staple up heating .The floor covering is 3/4 inch hemlock planks with 1/2 maple hardwood.This is the original floor from 1912 it is very dry ,so should I be concerned about humidity or lack there of?.

    Radiant will not affect the humidity of the house. If this floor has "cured" for a hundred years, you probably won't hurt it with radiant unless you are dramatically overheating it....


    ....which you might have to do if the house isn't insulated up to modern standards. As AJ said... a heat load calculation is the first, non-negotiable step to any heating system install. Especially radiant!
