electric water heaters

Think about all of the hot water you use every day.  For showers and baths. For dishes. For laundry.  Hot water is a necessity and, with an energy efficient water heater, it is affordable, too.  Choose an energy-efficient electric water heater for your home to get the most out of your energy dollar.  

The Right Water Heater for You

The efficiency of your water heater will be determined primarily by what type of water heater you choose and, in some cases, its capacity.  The most common water heater is the storage water heater.  These heaters maintain a reserve of hot water that is ready when you are.  Choosing the right size for your needs will increase your energy efficiency. 

Compared to other options, electric water heaters are the cleanest and quietest. They're also the least expensive to buy and install. When all the costs are considered, electric water heating is a smart choice.

CMP recommends you work with a professional to choose the best location and do the installation. With an electric water heater there are no combustion by-products, no open flames, and no need to vent, so your heater can go just about anywhere it will fit. Consider placing a new hot water heater close to the room that uses the most hot water.  Usually that's the bathroom. The less distance the hot water travels, the more efficient your system will be.


For additional energy savings, lower the temperature to the lowest setting that provides you with sufficient hot water.  For many households, 120 degrees will be a reasonable setting.  In addition to saving energy, you will also reduce the risk of scalding, a factor especially important in homes with small children.

For Best Results

If your water heater was installed before 2004, you may be able to boost its efficiency by adding an insulation jacket to your water heater.  This will reduce the amount of heat lost through the walls of the tank and reduce the amount of energy you need to heat the water.  Most newer models come with hefty insulation, so always follow the manufacturer’s recommendations regarding insulation jackets.  You can also boost your energy efficiency by adding extra insulation to your hot water pipes, which will reduce the amount of heat lost on the way to your faucet.
