Choosing a Energy Efficient Electric Water Heater with a Tank

Read quick facts about 5 manufacturers of energy efficient electric water heaters with tanks on the web, read what they are and find quick facts about 5 manufacturers.

When I told the plumber to just bring a new one and install it, he plumber said that the energy rating was about 85% for $800 and more than double for a 93% rating, I chose the cheap model. The plumber came on Thanksgiving, bought the water heater and installed it. That was almost 15 years ago. I was able to proceed with my holiday plans with only a few hours of delay and annoyance.

With the economy as it is, increased awareness of global warming and the environment, and improved electric water heater designs, homeowners should be aware of their options and be ready to make a informed decision before the crisis hits.

My suggestion: Be aware that a tank water heater is likely to wear out in 12-15 years and plan for the upgrade.

Finding out if there's an Incentive Program

In writing this article, I went through quite a few articles, I'll include many of them. A web site offers a complete list of all incentive programs and their terms for every state in the country, see Sets Systems to find out more. This web site is rather complicated so unless you are sure what you want to do, you may want to just ask someone. Your local plumber, electric water heater salesman or manufacturer will probably be able to tell you if any of the incentive plans apply to your purchase of an electric water heater-they are motivated to know.

Choosing a Tank or Tank-less Electric Water Heater

The first decision you will have to make is between an old-style tank or tank-less electric water heater. I myself love my gas water heater because even during power outages I can still take a shower. The bad news for me was that many of the tank-less electric water heaters are more energy efficient than gas tank or tank-less water heaters. This didn't really surprise me since I had experienced how nice tank-less water heaters were when I visited my sister in Europe. The tank-less electric water heaters save energy by not heating water when it is unneeded. Costs are very similar to tank electric water heaters. An article by Consumer Search cites retrofit costs for tank-less electric water heaters as be difficult and best left to an expert because of the need for ¾ inch supply line and 4-inch venting. Also if your house is like our current house with most of the electric circuits maxxed out, a switch to a higher amperage circuit might cause difficulties.

My suggestion: get quotes from your plumber for both models.
