How about the best of both? Keep your hand-fed stove for extended power outages, and get a stoker boiler to evenly-heat your house and provide domestic hot water the rest of the time. That is what my brother did in his house...EFM boiler keeps every room whatever temperature you want, and the big-bad-Hitzer sits next to it waiting for the call to duty.
Also, most stoker boilers do not require any kind of constantly-running fan to keep the fire alive...they merely run the stoker motor a few minutes per hour to keep the fire alive. I think LL and Keystoker use a small fan that runs full time, but I'm not sure on the LL units. They use a few pennies of electric per hour to idle, but the savings is big when you get a warm afternoon and the boiler just "sleeps" instead of overheating the house.
