How to Choose the Best Gas Water Heater for Your Home
Choosing the right gas water heater depends on your household’s specific needs, the size of your home, and your energy-saving goals. Here are some things to consider when shopping for a gas water heater:
1. Assess Your Household’s Hot Water Demand
The size and number of people in your household will determine the capacity of the water heater you need. Larger families or homes with multiple bathrooms may require a 50-gallon or tankless model, while smaller households can opt for a 40-gallon model.

Installation requirements can vary based on the model. Tankless models often require a professional installation and may require upgrading your home’s gas supply. Make sure to factor in installation costs when budgeting for your new water heater.
