the system was designed in several zones. the first floor of the "north house" is one zone, the kitchen and great room two separate zones and the second floor of the "north house" a fourth zone. the layout was such that we could build all of the interior structural walls before installing the tubing for the hot water to run through. however, in order to be very efficient and heat each zone correctly a few of the non-structural walls had to wait until we could install the pex-aluminum-pex tubing.
we finally received the tubing yesterday and we were eager to install it. first we had to really clean all of the areas where we were going do the installation. all of the grooves in the sub-floor had to be free of debris to ensure that the tubing will not be punctured or damaged.

the loops of tubing can only be so long in order for the hot water to not cool down as it is running through the system, so that for example the second floor is one zone but is made up of three separate loops of tubing which go through the floor and then back up to the manifold location in a panel in the bathroom. matt and björn drilled holes in the floor for the tubing, and used a grinder to make sure the aluminum and wood around the holes was smooth in order to not puncture the tubing.

|the pex-aluminum-pex tubing must divert around the toilet, so that it |
does not melt the wax ring
|each tube is clearly labeled for return and supply for each loop, the manifold|
