can you do geothermal and radiant floor heat?
I am confused. We are looking for a cost efficient and comfortable way to heat the house that is also as clean and dust free as possible. Which is the best option? Do you do both? What is the source of the heat for the radiant floor heat and does it work to cool the house or must you do a forced air A/C unit anyway? Most important, which is the most economical at installation?? Please help!!!! Thanks!!
