I'm planning a remodeling project which will include converting existing attached garage into living space and adding an attached garage and additional living space. Since this is a grade level area I'd really like to add hydronic floor heating. My question is, would it be cheaper to add floor panels over the existing slab or have the floor cut and install pex tubing and repour the floor. I don't want to pour on top of the existing floor because of ceiling height restrictions. The area that would need to be cut would be about 800 sq ft.
I got a preliminary estimate for panels from WarmZone to the tune of $4300 (matierials only). I would do the installation. With flooring material (tile) this would add about about 1" of height to the floor.
The existing garage (about half the square footage of the living area part of the project) would need concrete poured anyway (1") due to a cracked floor and to level it with the existing floor. Also, I have to have some floor cut to accept a new drain line for an additional bathroom.
I'm unfamiliar with the costs involved in cutting concrete so any guidance would be helpful.
