World Executives Digest | What would cause no hot water in the house? | Did you know that 780 million people in the world still do not have access to clean and safe water? This fact can help to put a lack of hot water into perspective. Of course, in the Western world, we generally take hot water for granted. But, the fact is that it is still a luxury or unobtainable item for many people around the world.

We notice the hardship of surviving without hot water best when we have no hot water. The first thing you’ll want to do when you realize this is to contact your local plumber and get them to take a look at your system. In fact, it’s a good idea to contact an expert in your hot water system and get them to resolve the issue.

However, that shouldn’t stop you from being aware of what the issue is, you may even be able to resolve it yourself.


The most obvious issue is that the hot water heater is simply not getting power. Even a gas-powered water heater will need electricity to tell the water heater to come on. Electricity will create the spark that ignites the hot water heater.

Of course, an electric water heater uses electricity and no power equates to no hot water.

Check your breakers and your hot water circuit as well as ensuring power is on to the rest of your house and your neighborhood. You can also consider buying electric showers at Kitchen Home, which have bigger control over hot water.

Size of Unit

The size of your water heater should be dictated by the number of people that live in your home. The higher the number the greater the size of the tank.

Put simply, if you have children and they are using the shower more, you’re likely to run out of hot water simply because the tank isn’t big enough. If this is the case you’ll have to add a second tank or install a bigger tank. 

Assuming your hot water needs haven’t changed then it could be that one of the heating elements has failed. The good news is that the element can be replaced surprisingly easily.


One of the most common issues with a lack of hot water is actually leaks in the system. These can reduce the pressure in your system and will prevent the hot water from reaching temperature as there will be a steady supply of cold water entering the system. This will replace the leaking water and prevent the tank from heating up properly.

You’ll need to inspect all the joints in order to find any leak and then replace the joint. This will hopefully restore the hot water to your home.


The inside of your tank is favorable for rust. There is oxygen, metal, and water. Most tanks have an anode to prevent the heating element from corroding. However, ids this has been eaten away the rust can start to coat and corrode the bottom of the tank and the heating elements. This will reduce the efficiency of the heater and prevent you from getting the hot water you want, and need.

Knowing what the problem is can help you be prepared for the repair bill. But, it is always best to get the professionals to take care of it for you.
