What Size Water Heater For A 3 Bedroom, 4 Family Home?

We currently have a 56 gallon, but i believe that it is too large for the home. We have a 3 bedroom, 1 1/2 bath home. 4 people living inside.

    a typical size is a 40gal but it depends on bath size,Jacuzzi tub ,etc. i used to have an 80 gal, and it went out ,so i replaced it with a 40 gal and the cost of my utilities went down by over 100 dollars. a 40 gal should be more than enough for your family size. also be sure not to have the heat themo, any higher than 130* f. also get one with an energy saving symbol on it.

    I would say a 50 gallon heater is the minimum for a three bedroom home with four people living there.
    When our children were still living at home we had a 50 gallon heater and it was adequate but not oversized.
    There is very little down side to having an over sized heater and a lot if it is too small.

    We fixed our place like a duplex. My son & family (3 people) in lower lever with full bath, dishwasher, washer/dryer. Main level has (2 people) full bath, whirlpool tub, washer/dryer.
    We have a 40 gallon tank for the 5 of us. Washers set at cold or warm wash. Whirlpool tub filled during non-peak shower times. We have had no problems.
