Haven’t had to use our generator this winter either, its actually a rare occurrence that we need it in the winter. Live on a state highway and the state park is hooked up after us so they tend to like to keep the lights on at the cabins etc. Usually spring or summer when a severe thunderstorm rolls thru is a greater chance of losing power.
Happy with the G400, heating a 2800 sq ft farm house that had the last addition in 1908. Heating a 40x45 shop plus 120 foot of sidewalk, used less wood heating everything with the G400 than the old boiler used to heat just the house and sidewalk. But was a milder winter as well. Used up about 2 cases of spray foam in a can in the shop and a couple rolls of fiberglass tightening everything up in the shop, plan on some ceiling fans between every other rafter by next winter and pretty sure a G200 would be fine then, especially if I can come up with a little extra coin and finish changing out the last 14 wood framed single pane windows in the house.
