6 Reasons Why Your Ariston Storage Water Heater Is Not Hot

A lack of maintenance and heavy usage can cause your Ariston water heater to stop providing hot water. We have listed down 6 reasons why your Ariston storage water heater is not hot.

  1. Demand Is Too High


If your Ariston water heater is not producing enough hot water, the unit might be too small to meet the needs of your family. If you do not have an undersized unit, chances are that either both or at least one of its heating elements have failed.

  1. Sediment Buildup

If you have a hard water supply in your plumbing system, it might indicate that there is a sediment build up in the heat exchanger or on the bottom of your storage water heater.

  1. Incoming Water Is Too Cold

The Ariston storage heater has a dip tube which ensures that the cold water entering the water heater does not mix with the hot water in it. If the dip tube gets damaged, it might cause the water heater to leak.

  1. Thermostat Problems

If due to an electrical problem that the water from your heater does not come out hot, try to check the thermostat and make sure it is set in the right way.

  1. Reduced Incoming Water Pressure


One of the most common reasons behind low water pressure is sediment and other debris (e.g., calcium deposits and rust) collecting within your water pipes. To resolve this, you may choose to install a new water heater.

  1. Worn Out Water Heater


If your water heater is too old and has worn out, it is unavailable to provide hot water. In this case, it will be best to opt for a new Ariston storage heater to enjoy hot water again.

Aside from water heater not hot issue, you may also encounter leaking issues. Learn more about the possible causes of an Ariston storage water heater leak.


Possible Causes of Ariston Storage Water Heater Leak

Ariston water heater leaks can be quite troublesome for homeowners in Singapore. There are a few possible causes of Ariston storage water heater leak:

  1. Rusty Water Heater Tank


Your Ariston storage heater is made of steel –  which is mostly made up of  iron. You will be able to identify this issue if your tap water comes out rusty – water is usually brown in color.

  1. Sediment Buildup


Sediments will begin settling at the bottom of your Ariston water heater. This may create an insulating layer which increases the time needed for a water heater to heat the water. This may cause overheating and deteriorate your storage tank.

  1. Internal Pressure


In the situation that the relief valve is leaking continuously when it is not heating up water or the water heater has not been turned out for some time.

  1. Inadequate Insulation

An improper amount of insulation on your Ariston water heater’s pipe may cause a rupture. An uninsulated pipe can get quite cold and the water inside the tank may begin freezing.

If you are experiencing the said problems above, you should be aware of the things to do when your Ariston storage water heater is leaking.


What to Do When Your Ariston Storage Water Heater is Leaking

If your Ariston storage water heater starts leaking, it might be one of the signs that show something is wrong with it. Here is a list of what to do when your Ariston water heater is leaking.

Confirm the Cause Of The Leak


Check out any nearby appliances and the overhead pipes for leaks or drips. Use a mop to remove the collected water, and after some time, see if it collects yet again. If the storage water heater is the one causing the leaks, the puddle will be forming again and again.

Disable the Power Supply


Since the Ariston water heater is an electrical water heater, there might be chances of electrocution. You can disable the power supply by using the circuit breaker box.

Shut Off the Water Supply


In case of a serious leak, then you can turn your dial gate valve clockwise or pull down the handle to close the valve. You can also shut off the main valve to stop the leakage completely.

Drain the Tank

The next thing you need to do is to drain your Ariston storage tank by doing the following:

  • Find your heater’s drain valve (which is present close to the bottom) and attach your water hose to it.
  • Run your hose to a floor drain.
  • Open your valve. Now, at this stage, you may observe that the water does not flow properly, or it does not flow at all. This is simply because a vacuum is present in your Ariston storage heater.
  • To break this vacuum, just open any of the hot water faucets in your house. This will allow air into your water tank and let it drain with ease. Once there is a good flow, the entire tank should be drained fully in approximately an hour.

Call a Professional

You can try to fix the water heater leak if you could identify the cause of the leak. In the event that you cannot repair the water heater, consider calling a professional to help you repair or replace your water heater.

In some cases, when homeowners do not know how to choose the right size for their heaters, they encounter more issues other than water heater leaking. That is why you should also be aware of how to choose the right Ariston storage water heater size.


How to Choose The Right Ariston Storage Water Heater Size

Every household may require hot water for various activities such as bathing, washing dishes, washing clothes and other purposes. There are several factors which you can take into consideration when deciding the right Ariston water heater size for your home.

Physical Size of Heater


The size of the water heater is an important factor to take into consideration as there is limited space in the bathroom. The capacity of the heater is directly proportional to the size.

Household Size


The amount of hot water required will depend to a great extent on the number of family members in the household. This will ensure that hot water is quickly available for bathing and other purposes. Family members do not have to wait till the water becomes hot.

Flow Rate and Temperature Rise


The preferred temperature of the hot water might vary across family members even though 65 degrees centigrade is preset temperature for some water heaters. If a higher temperature is required, the heater should have a better heating capacity.

Peak Hour Demand

You should also consider the peak hour demand in the house for Ariston water heater selection. It is advisable to calculate the amount of water required in bathrooms and other areas during peak hours before finalizing the right size.
