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.
How Long Do Water Heaters Last. — The majority of water heaters last between eight and ten years. While ten is the age at which heater replacement is generally recommended, the actual need to replace a heater could arise before or after this timeline.
Tankless water heaters typically have a lifespan of 20 years or more. Traditional water heaters with standing water tanks can last around 10 to 15 years before you notice signs of age.
When should I consider replacing my water heater? If you suspect your water heater is more than 10 years old—it is time to consider replacing it before you're left with an emergency decision. To determine the age of your water heater, you'll need to identify the Brand Name and Serial Number for your unit.
Either due to the high load on the electric system or short-circuit, it is possible that an MCB (Miniature Circuit Breaker) has tripped and has shut down the power supply to the electrical socket powering your water heater, and that is why your geyser isn't turning on.
Our well trained and qualified plumbers will always make sure that a geyser is replaced and repaired according to SANS 0254 standards and specifications as your safety is our concern.
Many are installed above the ceiling, and so noticing any issues with them can be tricky. If you happen to hear dripping in your ceiling, or notice any wet spots or water leaking from that area, it could be a sign that geyser repairs are urgently required.
The average lifespan of a traditional water heater is about 11 years, but they can last anywhere from 6 to 15 years. Factors like how often you use hot water, the size and location of your water heater, the quality of your water and how often you maintain it all play a role in how long it will last.
Hard water can cause sediment to build up in your water heater, leading to corrosion and shortened lifespan. We recommend installing a water softener or using a filtration system if you have hard water. This will not only extend the life of your water heater, but it will also improve the quality of your water overall.
Absolutely! After 20 years, your tank water heater is well past its life expectancy. If you have a tankless water heater, it's approaching its life expectancy. At this point, you should expect additional repairs from wear and tear.
The System Age
Most systems can last from 15 to 20 years. If a water heater is older than 20 years, it's usually better to put in a new system, even if the current water heater is working adequately. A decline due to age is going to start soon, and it's best to get ahead of it with a new water heater.
The current, estimated cost to replace and install a geyser is about R7 500 – so budget towards this amount of savings, at the very least, if you are not insured. The average household uses a 150L geyser. A steel 150l geyser cost about R5 500.
Turning off your geyser will not save much electricity according to most professionals, and this is included Eskom's Geyser Fact Sheet. You will only see 10°C of heat loss in the 24 hours after your geyser is switched off. This is what is called 'standing loss' and this is also a quality standard set forth by the SABS.
Regularly servicing your geyser will increase its life span. A geyser should be serviced every 3 to 4 years in areas with good quality water. However, in areas with hard water or low water quality, your geyser should be serviced every 2 years.
Sediment can block or clog your water heater's pressure relief valve and can cause your water heater to lose efficiency. If the pressure relief valve gets blocked, it's no longer operating as a safe pressure relief outlet, and the safety of the water heater tank is compromised.
If your water heater is more than 10 years old, leaks around the base of the tank or if it works erratically, it's probably time for a replacement. You may also choose to upgrade to a more energy-efficient model to cut your energy expenses. In some cases, repairs and troubleshooting can save your existing water heater.
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.
As stated above, the average lifespan of a water heater is about 8 to 12 years. If your water heater is approaching or exceeding this age, it may be time for a replacement. If there is any sediment build-up in the tank, it will eventually solidify at the bottom.
Once you decide to (or are forced to) replace your current water heater, there are a few decisions you need to make to get the process started. If there are no issues or complications, a licensed plumber should be able to complete the process in 2-3 hours.
Beware of Turning Your Geyser Off
This, he says, can lead to welding damage over time and may result in a Geyser bursting. Ryan Moore, Managing Director of Roto Rooter, says that while a Geyser can be switched off during the peak demand period, it should be switched on before 10h00 to prevent damage to the Geyser.
If your geyser drains when you have a water outage, there is a high likelihood that your element will burn out.
