With energy saving being the current fad you might get along with the existing setup for quite a while. And, people move in 7 years, on average.
If you get new appliances, try to get 'soft start' to reduce the start-up current surge.
How much of your house's energy input is handled by natural gas/propane appliances?
If eventually necessary, and if there is no penalty for doing
an incremental rewire vs. a complete, one-time rewire
then go incremental.
