Not saying this isn't bad, but as long as the blackouts are frequent but short, I feel like heating is probably the least of our worries? Heat stays in a room for a while and most heaters don't stay on all day anyway. This is, at least, from my experience living in India (in a part where it does get cold). Heating was whatever since the blackouts Werner long, and since blackouts are normal, we had backup generators and UPSs for things like WiFi routers and elevators.
