What type and how would I install Hyponic heat under the subfloor of my mobilehome (which is in no way mobile anymore). I live in Texas so the winters are pretty mild. My central heat went out and it is extremely expensive to run since I only have electric heat. I am planning on replacing my fireplace with either a wood burning stove or insert. Then I am interested in doing the entire underbelly of the home with the Hyponic heat even if that means installing a seperate water heater for it.
What I need to know is if this is possible, what it would cost for a 54x28' home, and if a 50 yr old "beginning DIYer" could undertake this with the help of a teenager?
