Does it have to be a new construction or can it be installed on an old house? And if yes, how much for a 2000sf home? Rough estimate, I won’t hold you to it??
For parts and labor, pencil in $20/sf for any radiant system. Warmboard will have higher material costs (higher quality, better performance), but lower labor costs. But there are many variables to consider in this number, including where you are building. If you want to give us a call, we can get you a much more accurate number for you based on the specifics of your project.
