Reasons You Should Change your Hot Water System

. 4 min read

Water heaters typically last for 10-15 years. There are some signs that it is time to replace the water heater. How to identify them? Let us find out!

The water heater is one of the electrical appliances your family relies on. From cooking to bathing to cleaning, we all rely on the regular supply of hot water. If you ever face any issue with the water heater, you can also get a water heater test. Can you imagine getting up to take a cold shower?

But how do you know if your hot water system needs to be replaced? We're going to clarify how to decide whether you need to fix the heating system. Gold Coast Plumbing Experts can help you out with their expertise.

How to determine if you need to change your hot water system?

An Aged Unit

How old is the heating system? The duration of the water heater usage suggests that it needs to be fixed. According to the maintenance method, a standard water heater's service life should be 8-15 years.

Water efficiency is also an aspect to be considered when determining the lifespan of the equipment. If you use hard water, the machine may even be damaged within the guaranteed time if maintenance is improper.

If you remember its manufacturing date, you can know when you need to change it. If it has completed ten years, it's the best time to replace it rather than waiting for it to collapse completely.

The lifespan of the heating system will depend on the number of users in the residence.

A Leaking Tank

Water leakage is a serious problem for water heaters. If there is water around the appliance or an obvious leak in the water heater, it means that it needs to be replaced. A leaking water tank cannot be repaired.

Attempting to use a leaky water tank poses a risk of flooding or major failure. However, the water system or leakage needs to be tested. It is possible to patch certain types of leakage, such as when the pipe leaks but not the tank itself.

Here are some signs you might have problems with the tankless heating system.

Lukewarm or Cold Water

A functional water heater should supply hot water fitting on the thermostat. If the machine is providing hot water and suddenly starts to provide cold water, there is a problem.

If the thermostat regulation sees no temperature changes, the heating unit has burnt out. It means that you have to use a new water heater to restore the hot water supply.

The increased demand for hot water in your home can cause the water heater to produce cold water. Check the hot water requirement.

If the hot water requirement is too high, replace it with a new heater with a larger capacity.

Rust and Corrosion

Most rust and corrosion in the water tank are signs of the end of the equipment's life. If you find that the tap or the water in the shower is rusty, it means that the water heater needs to be replaced soon.

It clearly shows that it has worn out and could even damage your entire system. Rust in the storage container can impact your equipment like washing machines and dishwashers. It may also affect the pipe system.

Therefore, rust is a sign of the end of life of the water heater. It is also necessary to verify that reinforced piping cannot cause corrosion to prevent removing a functioning heating system.

Noise from the Tank

After a while, the water heater may start to make noise, especially when water is heated. If you frequently hear crackling and rumbling sounds from the water heater, the appliance may be worn out and is at the end of its life.

Noise is usually caused by deposits that have accumulated around the heater. Noise is generally caused by deposits when heated. The deposit corrodes the heating element and creates a layer (scale) on the heating element, hindering the system's efficient operation.

Constant vibration will make it worse, so it's necessary to fix your heating system.

Drain Valve Not Working

Over time, sediment will begin to build up at the bottom of the water heater tank. When deposit starts to build up, it can damage the inside of the water tank and eventually block the drain valve.

It is what prevents the water from flowing out. If there is not sufficient water coming out of the system to activate the drain valve, the heater should be replaced.

Sometimes a clogged drain valve can cause a leak. It is also necessary to fix or replace the heating system.

Increased Demand

The volume of the heating system is dependent on the family's needs. How many users or devices are in your home? Maybe you installed a water heater when your needs were limited, but they have grown over time.

There may be few water-using appliances in your home, but you've added more. These are just some of the factors that increase water demand and reduce equipment performance.

Therefore, to meet the accurate water requirements, it is necessary to substitute the heating system with larger efficiency.

Metallic Smell and Taste

Notice the variance in flavour and scent if you drink the water straight from the tap. If you realize that the water in the water tank has a metallic and peculiar smell, the water heater is malfunctioning.

It is mainly due to internal corrosion. Another reason could be rust in the hot water tank or worn heating elements. These metal parts in the water can be harmful to health, so the water heater should be replaced immediately.

Reduced Efficiency

It is very easy to judge if the heater is performing poorly. If your energy bills are increasing without the addition of new users or new devices, it indicates that your heater needs to be replaced.

Inefficiency means that the machines need more electricity to heat the same volume of water. It's important to change it if you've tried all the strategies to enhance performance, yet none of them succeeded.

Frequent Repairs

Frequent maintenance of the hot water system indicates that the system is worn out. If this happens after the water heater has been used for ten years or more, it must be replaced.

At this point, maintenance does little to save the day. You will likely solve one problem, and another issue will pop up. It’s better to replace it in this situation.
