How to Choose a Tankless Water Heater

The ideal size for a tankless water heater depends on various factors such as your household size, insulation level, and personal preferences. A general rule of thumb is to choose a tankless water heater with a capacity that is 10-15% larger than the average square footage of your home.

Factors to Consider

• Household size: Larger households require more hot water, so a bigger tankless water heater can handle it better. A general rule of thumb is to choose a tankless water heater with a capacity that is 10-15% larger than the average square footage of your home.
• Insulation level: If you live in an area with very cold winters, consider investing in insulation to keep warm water hot longer. This will also impact your tankless water heater's overall size and energy efficiency.
• Personal preferences: Some people prefer a warmer temperature for their showers or baths, while others like it cooler. Choose a tankless water heater with adjustable temperature settings if you need them.

Calculating Your Needs

To calculate your needs, consider the number of people in your household and the amount of hot water you use per day. A good rule of thumb is to have at least 10-15 gallons of hot water per person per day.
