We are new owners of a Harman Accentra Insert installed in 2008. Saw a huge jump in our electric bill when heating season started and are trying to tease out the pellet stove's role. (We have solar, oil radiation, and mini splits as well as the pellet stove.) Can anyone help me locate the Watt Kwh specs for Ignition and then running for this older insert? We have a Kill A Watt to measure usage and it is not looking good.
