What Is The Lifespan Of A Water Heater?
A standard water heater has a lifespan of eight to twelve years. Most tanks sold in the market today are steel lined along with porcelain or glass, and they can start to oxidize and deteriorate over time. Sometimes these tankless water heaters can have a slow leak, and sometimes the leak can be really dramatic, ruining the heater completely.
Most homeowners tend to use these water heaters for more than their allotted lifespan; some homeowners can use these heaters for fifteen years whereas some opt for twenty years. However, most tankless water heaters lose their efficiency over time due to sediment being built up. To make your tankless water heaters last longer than their average lifespan you will have to maintain it.
Keep on reading this article, and we will let you know about things you can do to extend you tankless units life.
Tips To Extend Your Tankless Water Heaters Life
Replace Your Anode Rod
Checking the anode rod is the first and foremost thing to do as it will help you in figuring out how long your water heater will live. An anode rod protects your unit from rusting by sacrificing itself. This rod is screwed on your water heaters head and made of steel wired usually by magnesium, zinc or aluminum depending on the water condition.
An anode rod can last for five to ten years, however; to extend the life of your tankless water heater make sure that you replace this anode rod before you tank starts to rust away or leak. Keep in mind; once your tank starts to leak, you will have to replace the whole unit.
Make Use Of An Expansion Tank
If you are using a closed system then fixing an expansion tank can help in doubling the life of your tankless water heater. When water gets heated up, it starts to expand for example if it gets heated from 45º to 120º it will expand by 2% so a fifty-gallon tank will have an extra one gallon.
Now if your heating system is closed your water will not be able to flow backward due to the valve present and will have no place to go. Since this extra water cannot be compressed, it will instead increase and decrease the water pressure rapidly thus putting stress on your water heater. This expansion and contractions can also put a strain on your plumbing lines and damage it.
Clean Out Your Tank Sediments
After some time your water heater may have built up sediment, and this can cause serious damage to your water tank. This sediment makes your unit work harder, decreases its efficiency and also corrodes the walls causing it to leak.
To prevent this from happening you must flush your tank out annually and prevent any sediment buildup. Turn off the electricity or gas and then place a garden hose to the drain valve located at the bottom of your water heater. Once connected, the sediment will start to move out from the hose so make sure to place the end of your hose in a tub or outside.
Repeat this step until the water heater is clean and the water coming out of it becomes clear.
Keep A Check On The Pressure Relief Valve
All tankless water heaters have a pressure relief valve. This is a built-in safety feature; this valve opens itself up as soon as the pressure of heat gets too much. This pressure relief valve also helps in protecting your water heater from damage and prevents risky explosions.
Checking the pressure relief valve will help in extending the life of your tankless water heater and also let you know if your unit is functioning properly. This valve also keeps you updated on your safety. Sometimes sediments and residue can get buildup and block the opening of this valve; make sure that this valve is checked regularly.
Install Water Softeners
Most areas have water with high mineral content and are known as hard water. This kind of water can lead to scaling which is due to the mineral that deposits on the surface of the appliance and starts to perspire. This can reduce the life of a tankless water heater drastically. In most cases, placing a water softener can help in reducing the damage caused to the plumbing system by this hard water.
