1/17/06: Watts Radiant PEX with oxygen barrier 1/2 inch pipes about to be covered in concrete for the ground floor slab.
Cheapest way to do radiant heat since heat spreaders are not required as with radiant under a wood floor. Kitchen area
pipes on the left are not as closely spaced since it will have tile which lets the heat thru better than carpet in the
living room area on the right. The brick chunks under the reinforcing wire are used to hold the wire closer to the center
of the slab for better strength and to keep the pipes nearer the top.
