The hot water system is one of the most frequently used appliances in every household. Due to various factors, even the best hot water systems will eventually wear off. Thus, every house owner should know when to replace the hot water system in the house. The replacement may not be necessary in all cases. So, let us first understand the factors that affect the life span of a water heater.

Hot Water System Maintenance

Factors that affect the durability

  • The type of system

Hot water systems can either be powered by electricity or gas. An electric heater has an average life span of 10-15 years. On the other hand, a gas-powered heater will last anywhere between 8-12 years. If the system completes its lifespan, it is always good to go for the replacement, even if it does not show any signs of wear and tear.

  • The quality of the system

The durability of a hot water system greatly depends on its quality. Houses that install high-quality systems from reputed brands can expect a longer lifespan of around ten years. If not, the system will corrode quickly and become defunct.

  • Frequency of use

The heater has to withstand changes in temperature for years together. Although it is built especially for the purpose, it cannot work forever. A hot water system that is used frequently will have a shorter lifespan. The frequency of use depends on a host of factors, such as the number of people in the household and what they do. If most members are working adults who stay outside for many hours, the user may be less. In such cases, the house owner can expect the system to last long.

When to replace the system?

An efficient hot water system is crucial to the smooth functioning of a household. If your heater starts showing any of the signs given below, consider replacing it with a new one.

  • Rust

Over time, dust accumulates in several parts of the heater. When it reaches a threshold limit, the hot water coming out from the taps and faucets will also have rust. It could be due to the dust accumulation in the pipes, valves, or inlet. An easy way to spot the source is to drain the tank. If it is rusty even till the very end, the rust is likely in the tank itself. It is essential to replace the system when the water gets rusty. Otherwise, it can lead to the next issue.

  • Leaks

Leaks are not just a sign of wear and tear. It is the most serious problem that one can encounter with a hot water system. When a rusty system is not replaced on time, the rust further eats steel parts and causes leakage.

Another reason could be the expansion of the metal. As the machine is subjected to numerous heating cycles, the metal within the tank expands. It can cause leakages on the floor around the tank. Other common causes include problems with the fittings or the temperature pipes.

  • Not heating/noise while heating

The most obvious sign that the system needs replacement is when it does not heat the water. It may occur due to overuse. Sometimes, the family grows, and this warrants high usage of the system. When the tank is unable to match the growing requirements, replacement is the best option.

Sometimes, due to damage or sediment buildups, the heater makes noise while functioning. Again, this is a sign that the house owner should consider installing a new system.

When one observes the signs mentioned above in hot water system, one should immediately consult an installation/repair service to solve them.
