The house I just bought was built in 1952. It's a 3 bedroom, 1 bathroom with the standard screw in fuses (total amps unknown). Presently I'm doing a remodel. Adding a third bedroom & extra bathroom, washer & dryer, dishwasher, newer & larger refrigerator, bigger microwwave, probably 3 window air conditioners and a tankless hot water heater which this house never had before. My question is should I upgrade to a 100 amp or 200 amp service to accommodate everything I'm doing. Thanks
