If your hot water is no longer coming out hot or is only hot some of the time, it may be time to replace the heater. Sometimes the devices and mechanisms inside will wear down or break, causing your heater to stop
Common signs that it's time to replace your water heater include its age (usually 10-15 years), rusty or discolored water, strange noises, leaks or pooling water around the tank, and insufficient hot water supply.
Water heaters show several signs of going bad, including lack of hot water, temperature fluctuations, decreased water pressure, strange noises, rotten egg smell, visible leaks, rusty or discolored water, and increased energy bills. If your water heater is over 10 years old, it may be time to consider a replacement.
While today's water heaters are better designed than older models, they still require regular maintenance in order to prolong their lives. With regular inspection, draining, and flushing, you can expect a gas water heater to last anywhere from 8-12 years and an electric water heater to last anywhere from 10-15 years.
Water Heater Lifespan
If your tank water heater is more than 10 years old, it may be time to consider replacing it. With proper maintenance, a tank water heater tank should last six to 12 years. A tankless water heater can last for more than 20 years. Check your water heater's warranty for the most accurate timelines.
The cost for an electric water heater replacement runs between $2,000 and $3,000, depending on the specific model and size you choose. Although you may purchase an electric water heater for a low price, they're typically more expensive to run than gas models.
Flush your water heater every six months or so. If you have harder water, or water that contains more minerals, you may want to flush it more often.
Sediment can build up over time in a water heater, shortening its lifespan. To prevent this, you should flush your water heater at least once per year. Flushing will help to remove any sediment that has built up and improve the efficiency of your water heater.

To test the element, use a voltmeter. Touch one probe to one screw of the element and the other to the opposite screw. A lack of resistance indicates a faulty element that needs replacing, while a resistance reading means it's functioning correctly. Repeat this process for the lower element.
Poor water heater performance can sometimes stem from an anode rod that's overdue for replacement. If you notice signs of poor performance, such as discolored or rusty water, sulfuric or rotten egg smells, popping sounds from the tank, or high heating bills, inspect your water rod to determine if it needs replacement.
A Corroded Water Heater Could Cause Significant Damage
If the tank rusts through, it could fail catastrophically and flood your home. You can avoid this disaster by replacing your water heater before it fails.
Installing a water heater isn't as simple as twisting and screwing a few tubes together to complete the project. Water heaters are usually connected directly to your home's plumbing and electrical systems. Installing all the necessary plumbing fittings can be quite complex.
Crackling and hissing sounds are perfectly normal to hear every once in a while in electric water heaters. If the sound is happening a lot, you may need to drain your tank to see if there is something blocking your heating element.
The life expectancy of a hot water tank varies depending on its size, how often it is used, and how well it is maintained. A standard 40-gallon tank will last between 10 and 15 years while larger tanks (50 gallons) have a lifespan of up to 20 years.
The short answer is yes: your hot water cylinder and your boiler should be serviced every 12 months.

If you are on a budget, a 40-gallon may be the better option for you. Water Heater Efficiency: When it comes to efficiency, a 50-gallon water heater is going to be more efficient than a 40-gallon water heater. This is because it will have a lower recovery time, which means it will take less time to heat the water.
-Reduced Efficiency: As scaling collects at the bottom of the tank, your water heater will become less effective at heating the water in the tank. -Corrosion: If your water heater goes long enough without a proper flush, you could also have corrosion attacking the tank itself, weakening its structural integrity.
The national average cost to flush a water heater is $160, but prices can vary in increments based on the tank size. A 30-gallon tank will cost between $90 and $120 on average, while a 70-gallon tank could cost anywhere between $180 and $250.
Keep an eye out for debris suddenly showing up in your water. If you notice sediment or any brown sludge coming out of your faucet, that's probably an indication that it's time for a water heater flush. If you see any of these signs, it's a good indication that your water heater needs maintenance.
