At Stillorgan Gas, we’re here to help you make the best decision for your home and ensure you always have hot water when you need it.

 

Sign 1: Age of The Hot Water Cylinder

 

Hot water cylinders typically last between 10 and 15 years. If yours is older than that, you may want to consider buying a new cylinder.


To find out the age of your hot water cylinder, look at the label on the tank. This label usually includes the date of manufacture. If you can't find the label or the date is unclear, you'll need to check your records or contact the manufacturer. 


Old hot water cylinders are risky. As they get older, they become less efficient, leading to higher electricity bills. They're also more likely to have leaks or other problems, which can lead to water shortages in your home. In some cases, the old cylinder may even stop working, leaving you without hot water. 


If your hot water cylinder is getting older than 10-15 years, it's wise to consider replacing it. This can help you avoid unexpected problems and ensure you continue to have a reliable supply of hot water. 

 

Sign 2: Water Temperature Not Constant

 

If the temperature of your hot water keeps changing, it could be a sign that there is a problem with your hot water cylinder. This instability can make everyday tasks like bathing or washing dishes frustrating and uncomfortable.


Some common causes of water temperature fluctuations are:


Bad thermostat: The thermostat controls the temperature of the water in the cylinder. If it is not working properly, the water can get too hot or too cold.


Sediment build-up: Over time, minerals in the water can settle at the bottom of the cylinder, forming sediment. This build-up can obstruct the heating elements and make it difficult for the cylinder to maintain a steady temperature.


Worn heating elements: The heating elements in the cylinder can wear out over time, causing uneven heating of the water. 


When the water temperature does not stay constant, it affects your everyday comfort and can be uncomfortable. No one likes a shower that suddenly turns cold or dishes that aren't cleaned properly because the water isn't hot enough.


If you notice the water temperature constantly changing, you should have your hot water cylinder checked. Fixing or replacing the cylinder can keep you comfortable and give you hot water when you need it. 

Keeping a good cylinder means you have to invest in a good product which can be useful for keeping warm in winters.

If you notice colorless or rusty water coming from the tap, this is a sign that your hot water cylinder may have a problem.


How rust and sediment enter the water:


Rust: Over time, the inside of the cylinder can rust, and these rust particles can get into your water.


Sediment: Minerals in the water can settle on the bottom of the cylinder, forming sediment that can also change the colour of the water. 


Health effects:


Drinking or using colorless water can be unhealthy. Rust and sediment can contain harmful bacteria and other contaminants. 


Long-term damage:


To the cylinder: Rust and sediment can corrode the inside of the cylinder, weakening it and eventually causing it to leak or fail completely.


To the plumbing: Colorless water can damage your plumbing system, causing blockages and reduced water flow.

Sign 5: Strange noises in Hot Water Cylinder


If your hot water cylinder is making unusual noises, this could be a sign of trouble. Here are some common noises and what they could mean:


Types of noises in Hot Water Cylinder:


Gurgling: This often indicates a build-up of sediment at the bottom of the tank. The sediment traps water bubbles, which create a gurgling sound when heated.


Popping: Like gurgling, popping sounds are usually caused by water bubbles trapped in the sediment.


Hissing: A hissing sound could mean there's a leak causing water to escape and hit the hot heating element, or it could be a sign of pressure problems.


What these sounds indicate:


Sediment build-up: Over time, the minerals in the water settle at the bottom of the tank, forming a layer of sediment that interferes with heating.

Pressure problems: If the pressure inside the tank is too high, this can cause a hissing noise and could indicate a leak or tank failure.


Solution:


Flushing the tank: Regularly flushing your hot water cylinder can help remove sediment and prevent buildup.


Checking the pressure relief valve: Make sure the pressure relief valve is working correctly to avoid pressure problems.


When replacement is necessary:


If flushing the tank or other maintenance doesn't stop the noise, it may be time to replace your hot water cylinder. Persistent noise can be a sign of serious internal problems that could lead to a leak or complete breakdown. 

 

Sign 6: Reduced hot water supply

 


If you're getting less hot water than usual, there may be a problem with your hot water cylinder.


Possible causes for a reduction in the amount of hot water:


Sediment build-up: Minerals in the water can settle at the bottom of the tank, taking up space and leaving less room for hot water.


Worn heating elements: Over time, the heating elements in the cylinder can wear out, making it difficult to heat water effectively.


Bad thermostat: If the thermostat isn't working properly, it may not heat water to the right temperature, reducing the amount of hot water available.


How sediment build-up affects capacity and efficiency:


Reduced capacity: Sediment takes up space in the tank, which means there's less room for hot water.


Reduced efficiency: A layer of sediment can act as an insulator, making it difficult for the heating elements to heat water. This means the water heats up more slowly and the cylinder uses more energy.


Deciding between repair and replacement:


Repair: If the problem is minor, such as a faulty thermostat or a small amount of sediment, repair may be sufficient. Flushing the tank to remove sediment may also help.


Replacement: If the cylinder is old or has a lot of sediment built up, it may be more cost-effective to replace it. A new cylinder will be more efficient and provide a reliable supply of hot water.
