They're specifically talking about replacing gas appliances with heat pumps -- e.g. heaters. A moderate sized 3-ton unit uses around 5kw to heat on cooler days where a gas furnace might use 0.1kw to turn the blower motor. I live in a weird house that has 3 gas furnaces but only one of of the furnaces has AC attached at the moment. I'm going to swap out two of the three for ducted heat pumps, so my peak electrical load in both seasons will increase by roughly 5kw. Replacing the third furnace (with the AC) would surely reduce the cooling electrical load since it's old and outdated, but would add another few kw to my winter heating load if I were to do so.
