An Energy Star Water Heater Can Save You a Bundle

If you are looking for a way to significantly lower your utility bill you can look no further than your hot water heater. Second to only your in home heating and cooling system, your hot water heater is the biggest offender to inflated bills. In fact, these outdated more standard water heaters are using energy whether you are using the hot water or not. Standard water heaters work off of a tank. What this means is that at any time during the day they are running to keep anywhere from 30 to 70 gallons of water at a temperature of about 120 degrees F. This is simply a waste, as for the good portion of the day you may not be actively using your hot water or even at home at all.

For an answer to stopping this wasted energy and then pass those savings onto you from your utility bill you can do well to outfit your home with an Energy Star water heater. These water heaters have proven to save you anywhere between 7 and 30 percent off of your current bill, which definitely add up. There are five different kinds of water heaters that can earn an Energy Star certification: storage, on demand / tankless water heaters, gas condensing, heat pump, and solar.

Storage Water Heaters

Storage water heaters are what you most likely are already using in your home today, yet newer models are coming out that are more efficient than the previous makes. These are still relatively larger energy consumers, but in order to merit the approval of an Energy Star certification they must be at least 7 percent more efficient than those of the past and with an Energy Factor score of 0.62. The upside is you will save money in the immediate purchasing and installation as these are the cheapest of the energy savers, but you will not be saving as much cumulatively over the years.

On Demand Water Heaters

Tankless water heaters, also known as on demand water heaters, don't have a reserve of water and instead heat the cold water coming into the pipes as they are being used. These will save you up to 30 percent off of your utility bill, and to be Energy Star Certified they must have an Energy Factor rating of 0.82. Most of them meet these guidelines easily. There is one drawback to a tankless water heater. Because they heat the water as it is being used, the more hot water you have running at once, (say showering while running the dishwasher), the temperature may not be as high as you'd like.

Gas Condensing Water Heaters

Gas condensing water heaters may appear much like a storage heater but operate differently. They are able to more efficiently heat up the water that is being stored and will save you more than those that are storage water heaters. These must be rated at least 0.8 on the Energy Factor to be an Energy Star which puts them way ahead of the storage options and are a good choice for heating water for a big home. The draw back is that they are going to be much more expensive than the tank water heaters.

Heat Pump Water Heaters

Heat pump water heaters work off of electricity and this allows them to be much more efficient. Those with an Energy Star seal of approval will have a rating of over 2.0. This is much higher than any others. Yet while they are the most efficient at heating water, they will be drawing energy from electricity alone which is more expensive than those running off of gas or propane. What this means to you is you may not be seeing much of a savings in the amount of your electric bills.

Solar Water Heaters

Finally, solar hot water heaters work off of the light of the sun by converting it into energy to heat up the water. While these will not use any of your home's energy, they don't always come with an Energy Star certification due to the fact that many of them aren't large enough to generate enough hot water to make much of an impact. Yet if they are rated with an Energy Factor of at least 0.5 they will pass.
