How to Replace Water Heater
Before you rush out to buy a new one, you'll want to find out which type of water heater is most efficient. Your decision will be heavily predicated upon whether your home is set up to run an electric or a gas water heater. One general piece of advice is valid regardless: Don't assume you need to buy the same size water heater as you currently own. It is possible that you can install a smaller water heater if, in recent years, you have replaced other household appliances, such as dishwashers and washing machines. Newer products often include power and water saving features, and thus, you might be able to buy a smaller water heater that will cost less money and use less energy. Whether your requirements dictate gas or electric, learning which models are most economical is fairly straightforward. Federal regulations require that water heaters display Energy Guide labels. These labels include the Energy Factor (EF) that measures the overall efficiency of a model; the higher the number, the more efficient it is. The labels also will have a First Hour Rating (FHR) that indicates how many gallons of water that model will produce during a peak usage hour. Additionally, you can get energy savings information and rankings on some of the most popular brands of water heaters through consumer organizations and reports. A word about on-demand water heaters: On-demand water heaters, also called tankless water heaters, or spontaneous water heaters, can be fueled by either gas or electricity. This design is much more efficient than standard models. An on-demand water heater is smaller and does not keep a reservoir of heated water on hand for anticipated use. Instead, as soon as you turn on the faucet, the fuel source fires up and the hot water is delivered. This type of water heater requires some refitting during installation in order to provide powered venting and possibly a larger gas line, so it is best to hire a professional to do the job. On-demand water heaters are especially practical for small apartments or single-person households. Larger households will require multiple units. Once you have installed your new, energy efficient water heater there are even more ways to increase its efficiency. Remember to purchase insulation blankets, lower your thermostat, add an overnight shutoff timer, install heat traps, insulate your pipes, and be diligent about regular maintenance. If you take these steps, you can rest assured that you will have the most efficient type of water heater available.
