As I said in an earlier post, we got delayed in our construction over the summer. We got a six-month extension on our building permit, so mid-December is our new target for completion. Still lots to do, but now that the hot weather has broken I am able to get more done. My #1 priority is to get the heat tubing in place so we can schedule the final concrete pour(s). (#2 priority is to get the rooftop solar collection tubes up.)
Here is the 1000′ roll of 5/8″ Uponor AquaPEX tublng I am putting down. The make-shift support of sawhorses, pipe clamp, and 4″ PVC pipe is working OK, though at first it took two people to unreel since the roll weighed in at 86 lbs.
The first step was to put rosin paper up to protect the painted walls from concrete splash when the final pour is done. Next was stretching out poultry netting that I will attach the tubing to with zip ties — not really sure about this method but I read about on the Internet so it has to work well, right? Right?? I started with the trickiest of the three 300′ tubing loops, the one under the loft. Among other challenges was the fact that we had to thread the loop through the wall between the bedroom and galley kitchen.
It took 4 days but the first heating loop is now complete. (FYI, I HIGHLY recommend that you not wait until you are in your late 50’s before undertaking something like this!) The only hitch was that I had miscalculated the layout and end up with some left-over footage that I had to get a little creative with around the bedroom closets. (Besides from the one time I kinked the tubing, but that is exactly why I chose PEX-a rather than -b or -c: you can fix a kink with a heat gun or hair dryer).
