Central heat pumps are like $5k more and you won't need gas installed or pay the plumber to run lines. 2. 200amps is common now and $200 more than 100 amp. Ovens and heat pump waters heaters need the 200amp panel. Plus size, more breakers than older homes for dedicated appliances. 3. Rated breaker is sized for 80% max load, 2 50 amp breakers != 100 amps. Stoves are an exception for NEC reasons. 4 What homes are built with a gas only, no electricity needed heating? We had a 2 week electricity outage in our area and some water heaters need a fan for the vent pipe. 5. Electricity usage has dropped so we are consuming less KwH and high efficiency hvac systems also use less. If you are worked about power outages, a <$1,000 gasoline generator would power essentials for one room.
