The answer to 'difference between gas water heater and electric water heater' is that gas water heaters use natural gas or propane to heat the water, while electric water heaters use electricity. 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 and maintain, but can be more expensive to operate in areas with high electricity rates.
The choice between a gas or electric water heater will depend on factors like the available utilities, your home's layout, energy costs, and personal preferences. In general, gas water heaters are a better choice for larger households or homes with high hot water demand, while electric water heaters may be more suitable for smaller homes or those with limited access to natural gas.
