Oh yea , right B4 I got out of the binnus they ( salesmen) came around with the plastic pipe w/crimpers that went into/under a wooden floor, If thats what your talking about. And like you said a warm floor cant be beat....exept maybe a warm toilet seat lol !check out radiant floor heat with pex..........simple and easy to do. Very silent. Standard cheap water. The pex connectors are not bad. you would only need a few and there are some cheap crimping tools for the few connections you would be doing. Its just another option to consider. OH and your bare feet would be warm everytime they touched the floor.
