Will your next water heater be gas or electric? The choice requires you to consider cost of installation and operation, as well as safety. Electric water heaters are usually cheaper to buy and require less expense to install.
If there is not already a gas supply run to your home, this may be a significant cost advantage. Not only are electric water heaters cheaper to purchase, but they require only water and electric connections, already existing in most homes. In addition, the need for the extra smoke and carbon monoxide detectors is eliminated, as no fuel is being burned on the spot.

Modern electric water heaters can be very efficient to operate, and may compare favorably with gas water heaters, when the total cost of purchase and operation is considered. However, both gas and electric water heaters should be installed by a qualified professional heating and plumbing expert. Common sense safety precautions as well as zoning requirements require the expertise of a trained professional. Your local plumbing contractor can help you make an informed choice, and properly install your new gas or electric water heater.
