How to Fix No Hot Water in Shower

A hot water problem can cause a lot of inconveniences. What should you do if your water heater fails? Find out why your water isn't getting hot and how to fix it.


When you do not have hot water, there are two possibilities: either the problem comes from the water itself, or it comes from the water heater, the device that heats cold water to make it hot. Here are the possible malfunctions with the hot water in the shower.

Why Isn't My Shower Getting Hot?

Whether your water heater is electric or gas, with or without a tank, malfunctions will eventually occur over time. The consequences of these failures are numerous, and we find in the first place the phenomenon of the water, which no longer heats. It is necessary to look at the various components of the equipment to determine the causes.

Electric Heater

First, you must check that the temperature of your water heater is correctly set. The problem may be with the temperature control or the equipment itself. If you have an electric water heater, it could be an element that has burned out.


Before carrying out a diagnosis with an open water heater, it would be a good idea to turn it off and reset the circuit breaker. If that's the problem, your water should be hot in less than an hour. Otherwise, call a professional who will be able to guide you better.

Shower Taps

The problem may not be unique to your shower. If it does not heat up, you will understand that the failure is generalised and must be a defective dip tube. In such a case, you must know that your shower is not broken.


The solution is pretty simple if dripping from the shower hose fitting. The shower hose can be unscrewed and examined in an entirely uncomplicated manner and without tools.


If the connection point of the entire fitting is leaking, things are a bit more complicated. This is usually due to a careless or worn seal of the pipe connections. To get to the bottom of the problem, you must dismantle the entire fitting.

Gas Leak

A gas leak from your water heater is potentially dangerous. If this is the case, or if you have the slightest doubt, do not hesitate to contact the gas company as soon as possible so that a technician can intervene quickly and avoid any damage.

Q: What kind of fuel does your boiler use?

A Leak in the Tank

The primary role of this type of device is to heat water. However, if a leak appears in the water heater tank and empties faster than it fills, there is likely very little hot water, or even more. Therefore, you will need to check connections between equipment and its components as well as the contents of the tank.

Boiler Does Not Heat Water

Do you know the reasons for your boiler failures? The water may acquire a slight temperature, but it does not go beyond being lukewarm, and no matter how much the tap is opened, the temperature does not increase.


One of the possible causes may be the water flow since boilers usually heat the water instantly. This means that once the tap is opened, the water passes through the boiler and is thus heated.


This is where the problem arises because if the water flow exceeds the power of the boiler, then it will not heat properly. If this is the case, the solution is quite simple. Just by reducing the flow, the boiler will be able to work efficiently.

Basic Faults of a Boiler

To give you an idea of ​​the most common problems your boiler may have and the possible causes, we have compiled a list of the most common faults and problems.

Boiler Does Not Heat Water

As we have mentioned, this particular issue can be caused by various reasons, including low water levels and motorised valve failure.

Frozen Condensate Pipe

A frozen heating pipe is quite ordinary for the condensation in the lines to freeze due to the cold generated at the time with the lowest temperatures. This creates a blockage causing the boiler to shut down as condensate backs up.


Thermostat Failures

It is pretty common for the accuracy of thermostats to decrease as the years go by. This causes the temperatures not to be appropriately set, and even the heating is turned on or off without any control.

Radiators Do Not Heat Up

When air builds up in the radiator, it causes the bottom of the radiator to heat up, but the top does not. Another cause may be that the pipes need cleaning, as they may have dirt clogging them.
