Nice job on the install Mark, the "smart" pump control is an excellent addition.
Where does the recirc loop return to? I'm guessing it runs back into the cold feed, triggering the heater when the pump is activated? I'm also curious about the aquastat install and how it is integrated into system.
I have a recirc pump on my NG fired conventional tank controlled by a simple timer. It's about 75 feet of 3/4" copper to the guest bath at the other end of the house, the pump is really a necessity. I added a 1/2" copper return line feeding back into the tank drain, with the total loop being around 150 ft. All lines are insulated through the crawl space.
I've thought about going tankless, moving the heater into an existing outdoor closet. The new location is adjacent to the kitchen and main bath, while the guest bath pipe would be cut to 30 feet or so.
