Finding the right size water heater

There a 3 Major water heater manufacturers in the USA with different types size, shapes and heaters. But which water heater is the right one for your family.

Plumbers say for 2 people a 30 Gal. standard heater is plenty big. 4 people need a 40 Gal. standard heater.

Reality check:

Let’s see — a 30 Minutes hour cycle uses 42-50 Gallons. A dishwasher in 30 Minutes will use 12-18 gallons of water. 1 toilet will take 1.6 gallons of water, a quick short shower 8 minutes with a with a 2 gallon shower head uses 8 gallon of hot water and if you preheat your shower 16 Gallons.

A good shower has a good showerhead that uses 6.5 or more gallons per minute and lasts 12-20 minutes 78.gallons- 130.gallons

In our family showers are first, than the dishwasher, and laundry through the day.
