About 40-Gallon Water Heaters water heaters
The 40-gallon water heater is the volume size for 2–3 person households — second only to 50-gallon in residential install volume. The 40G saves $30–$80 upfront vs the 50G and fits the same standard 22"-diameter footprint with slightly less height. For 1-bathroom homes and smaller households, 40G is often the right sizing.
