Well, after buying the stove in the spring and waiting all summer, I finally had the E2 installed this past week. I chose it over the AE because of its simpler design, less expensive parts (i.e. control board) and its almost all cast iron construction. She runs nice and quiet, although a bit too hot in this 90 degree weather!! My house was built in 1763, so not the easiest to keep warm without an oil truck having a reserved parking spot in the driveway. I'm looking forward to having the thermostat set above 62 for the first time!
