Energy Star Water Heaters – Energy Star has specific criteria for the various water heaters available on the market. To meet these criteria, a manufacturer has to apply its product to Energy Star testing. Furthermore, they also pay a fee that is for costs. However, the charge is mainly for laboratory testing for the product.
The water heater is test tested for the Energy Star specific criteria, and the numbers calculated. Furthermore, if the water heater meets or exceeds the requirements, then the manufacturer can put the Energy Star label on the product. Additionally, the Energy Star name is a sales point for many different brands.
Water Heater Anode Rod - Modern water heater tanks are constructed of steel with a thin glass lining to protect the steel from corrosion. The glass lining will eventually crack, but there is another level of protection from corrosion inside of the tank: the water heater anode rod.
What is a Water Heater Anode Rod?
A water heater anode rod is a long metal (usually magnesium or aluminum) rod that attracts the corrosive elements from water in order to protect the steel tank. Anodes are often screwed into the top of the tank and go almost all the way to the bottom. It is sometimes called the sacrificial water heater anode rod because of the way it sacrifices itself in the tank to protect the steel.
Because the molecules of magnesium and aluminum give up their electrons quicker than steel, rust will only occur on the anode rod while it still has metal to sacrifice. By diverting the rust to only occur on the anode rod, it can extend the life of your water heater. The water heater anode rod’s lifespan depends on a few different factors, namely: quality of the water, the water temperature, amount of use the tank gets, and the overall quality and construction of the tank. If there is salt added to the water as in the case of softened water, anodes corrode at a faster pace.
Anode Rod Options
Adding an additional anode rod should be considered if your model allows for it. By taking up more surface for it to absorb corrosion you can increase the life of your water heater even longer. However, it may not be a good idea if you are having odor problems as it can make the problem worse.
If you are thinking about adding an additional anode rode to your tank, make certain that both are made of the same metal. If one is magnesium and the other aluminum, the magnesium will be consumed more rapidly and you won’t get the desired outcome.
Another option is a powered anode rod or impressed-current anode. These do not sacrifice themselves in order to protect the tank, they instead are plugged into an outlet and stops the tank corrosion by releasing a continuous but small amount of electric current in the water, which prevents the electrochemical reaction that usually causes metallic corrosion. The benefits of a powered water heater anode rod are that they last much longer than a regular anode rod, they usually can take care of smelly water, and are better for the tank if you have soft water in your home.
Anode Rod Types for Different Tanks
There are two anode rod configurations, hex-head, and combo or outlet anodes. Hex-head water heater anode is often found on its own port on the top of the tank. Depending on the model, the hex-head might be exposed or under a plastic cap halfway from the center to the edge. Combo rods have a steel nipple that is plastic lined and used in the hot water port. Frequently tanks with a longer-term warranty have one combo and one hex head, although some just have one combo rod with no option for a second rod.
Anode Rod | Conclusion
Most tank water heaters last approximately 10-12 years, and they are not cheap to replace. Anode rods last 3-5 years and are about 20-50 dollars. Powered anode rods are about 250 dollars. By periodically checking your anode rod and replacing it when necessary, you can prolong the life of your water heater significantly.
Electric Water Heater Elements Diagnosis – It is truly very frustrating when you want to take a shower and there is a problem with the hot water heating system. You want to call a plumber for the fix but there are some easy fixes you can check yourself if you are a DIYer.
If you own an electric water heater element problem then this guide will help you solve your water heater problem. Diagnosis and repair of your electric water heater will require some basic mechanical and electrical competency so if you are not comfortable with the basics then the best thing you can do is to call a plumber to help you fix the water heater and get the hot water heater working properly.
Sometimes when you try to light the pilot it does not want to stay lit. You know you have a problem. Often times the problem turns out to be a bad thermocouple that needs to be replaced. But how do you know if the thermocouple is bad? Additionally, is it the thermocouple that is the problem, or is it something else?
Troubleshoot Standing Pilot Gas Water Heater – I am wondering how many people have had issues with lighting their pilot light on their water heater. I am sure it is many as I have responded to calls that turned out to simply going through the proper procedure to light the light and as complex as finding a bad gas valve to get someone’s hot water heater working again. I know it’s frustrating going without hot water especially when you don’t plan on lighting the pilot light and waiting the time it takes for the water heater to heat the water. (more…)
All About Hot Water Heaters - I have been transformed into a believer in tankless water heater systems. A few years back, I moved to Ukraine for professional reasons. When I first arrived in Ukraine it took a while for me to adapt to the culture, language, services, and way they do things here. Power failures, water outages, and occasionally natural gas outages are quite frequent here although it is tolerable and a minor inconvenience. (more…)
Water Heater Types - Selecting a hot water heater can be confusing especially if you are not aware of the types of water heating systems available to you. When you go out to buy a new car you want all the information you can get about the car you are buying from how economical it is to how reliable it is to the type of engine it has under the hood. (more…)
Water Heater Selection Considerations - Whether you are building a new house or getting ready to replace the old water heater in a home improvement project there are things to consider before making the decision which water heater to get to replace the old one or a new water heater for your new home. You want the best system for the money but you don’t want high utility bills to get the best system. (more…)
HVAC Tip - Did you know the human body produces approximately 250 BTU/h when sleeping? Here is a basic list of the approximate BTU/h produced by the human body for various activities:
Watching Television - 400 BTU/h (any sedentary activity)
Cleaning the house - 700 BTU/h (moderate activity)
Mowing the Grass w/push mower - 1800 BTU/h (heavy activity)
Running a marathon - 2400 BTU/h (extreme activity)
The number of people occupying a dwelling or space is a consideration in the load calculation for sizing air conditioning systems simply because humans do give off heat. BTW, the Matrix over blew the numbers. In the movie Morpheus states humans give off over 25,000 BTU's. Only the author of this website is that hot..............))))))
