The answer to 'which is better gas water heater or electric water heater' is that both gas and electric water heaters have their own advantages and the best option depends on your specific needs and situation. Gas water heaters are generally more energy-efficient and can heat water faster, but they require a gas line and proper ventilation. Electric water heaters are simpler to install, don't need a gas line, and are often less expensive upfront, but they can be more costly to operate in the long run.
When choosing between a gas or electric water heater, consider factors like your home's existing utilities, energy costs in your area, your hot water usage needs, and your budget. Both types can be good options, so it's important to evaluate your specific requirements to determine which one is the better fit for your home.
