My house is brand new, foundation poured 14 months ago. I want to install radiant heat in the basement using a tankless unit that will also provide hot water to the rest of the house. My basement (not incl. crawl space and bathroom) is about 700 - 900 sq.ft. with engineered hardwood.

What is the approximate cost? Can I install after removing wood or do I need to have concrete floor jackhammered out first?

You can install after removing the wood, but remember since the heat will be travelling through the pipes you are installing without some thermal resistance (insulation) the heat will go down into the slab more than will make it into the room (wood is an insulator). this won't be a problem if you have enough ceiling height.

Another option that is popular in Scandinavian countries is to install radiant heat in the walls instead of the floor. You would not need to install higher than 4' off the ground.

Depending on what is included you will be looking at $5 - $8 per sq ft plus the hardware to install a separate loop. Make sure you separate your domestic hot water from the space heating loops (legionnaire's disease).
