Water heaters are one of those appliances that works perfectly for a decade or more, until out of the blue they stop working. Some precaution and routine service can greatly extend the span of your water heater, and will also keep it efficient and safe.
Add a 2nd anode rod
The addition of a second anode rode will increase the life of your water heater. The anode rod is a sacrificial rod. It is made up of magnesium or aluminum which overtime goes through galvanic corrosion, thus preventing corrosion of the tank.
Use an Expansion tank
The installation of an expansion tank will help you double the life of your water heater especially if you are on a closed system. When water is heated from 10ºC to 48ºC, it expands by approximately 2%. If you are using a closed system, there is no valve which will prevent the water from back flowing into the water main. This water has nowhere to go. Since, the nature of water is not particularly compressible, it will cause rapid increases and decreases in water pressure. This expanding and contracting will lead to stress on both the water heater as well as your plumbing system, which can cause damage as well as premature failure.
Cleaning or flushing out your tank
If you have an older tank, then flushing out annually will allow you to prevent a buildup of sediments and will also lead to higher efficiency for your tank. Most newer model water heaters are self cleaning.
Installing a Pressure Regulating Valve (PRV)
If you have very high water pressure in your household, which is generally above 90 PSI, then, your water pressure can damage your appliances. This can also result in the failing of your water heater prematurely. If you install a pressure regulating valve, system pressure will be reduced. The decrease in system pressure will also reduce the wear and tear on all of your appliances. If you are installing a PRV, then it a good idea to install an expansion tank as well.
Install a water softener
There is always a chance that the area that you live in receives water with very high mineral content. This kind of water is often referred to as hard water. Hard water leads to scaling. Scaling is the precipitation of minerals which ends up getting deposited onto surface of an appliance. This potentially can reduce the life of a water heater.
Installing a water softener will help you reduce the wear and tear that the plumbing system has to go through due to hard water.
Maintaining your appliances is the key to have them running at maximum efficiency even after years of use. If you are facing any issues with heating appliance and would like a professional to take a look at it, then get in touch with Pro Plumbing.
