Yes, 100% with wood. A backup is just that, a backup and doesn't account for any part of the percentage unless you regularly use it and then it is not a backup it is a second source. My backup heat has not come on at all and is set for 60, the source is individual electric wall heaters. Each room has one and each heater has a stand alone thermostat. The kids' rooms are set for 60 and the stove room too but haven't fallen below 65 yet this year.
The heritage has gone through about a cord of softwood and our winter has been mild. The house loses 5-10 degrees overnight and reheats in about 2 hours. With modern construction or good insulation, is not difficult to deal with with wood heat.
