Their taller counterparts are more suited for large open areas that have a lot of headroom.

Determine the right capacity of water heater for your household
In order to calculate the right capacity, here are a few steps you need to follow:
Analyze the peak hour of hot water demand in your house. Is it at 7 am when all your family members take bath? Or at 8 am when your washing machine is operating simultaneously along with a dishwasher?
Once you have the peak hour with you, calculate the individual water usage in each activity and add them up. Here is a rough chart to help you out:
- Water used in shower: 10 gallons per person
- Water used in laundry: 30 gallons per use
- Water used is dishwasher: 15 gallons per use
Calculate all the other water requirements the same way, and add them up. This would roughly give you an estimate of the required capacity of the water heater.
It is important to have an idea about the specification of your water heater and all your appliances for easier repair and replacement. Did you already know the capacity of your water heater? Let us know in the comments.
