Progress being made on the right collector.
The 2 heat exchanger loops (one for each water heater) being secured to the tank. Zip ties, a mending plate and a generous dose of silicone kept the unruly 1" pex under control.
Another angle. To the left of the 4 heat exchanger pipes are the two inlets for the collector (just 2 black T's at this stage). The collector inlets pull from the bottom of the tank from the pumps outside the tank up to the top of the collector. You can also see the weatherstripping foam on top of the composite decking, this will create a nice seal for the lid later on.
Another shot of everything.
