Yes I am, Greg. I don't know how much of a benefit it will be with the fire on a lower burn all summer, but it will definitely help out in the cold weather.
One benefit I have already noticed: Before I connected the loop the oil burner would fire during moderate use, since the aquastat is near the bottom of the tank. The recovery is so fast that the water in the top of the tank (and out the outlet port) would be way over the 120 degree set point. Now with the loop installed the water temperature through the tank is more even, I haven't noticed the extreme hot water. I assume the oil burner also shuts off sooner due to the circulation of the water in the tank.
The only things left to do are insulate the pipes, build some kind of a jacket for the stove to wear during the summer so the cellar doesn't turn into an oven, and install a thermometer on the return line. I had a spirit thermometer installed before but the tube fractured, I need to find a new one. I can't really adjust the flow with the gate valve without a thermometer.
