A water heater that no longer heats properly can quickly become a frustrating problem, especially during periods of extreme cold or high demand for hot water. If your water heater isn’t providing the heat you need, there are a number of possible causes. In this article, we’ll explore the common reasons why your water heater may stop working properly, and how to remedy the situation.
Heating element problems
Heating element defective
In an electric water heater, the heating element is responsible for transforming electrical energy into heat. If this element is damaged or worn, it may no longer heat the water properly.
How to react?
If you suspect a problem with the heating element, it’s often necessary to call in a professional to check its condition. A technician can test the heating element and, if necessary, replace it.
Thermostat problems
Thermostat faulty
The thermostat regulates the water temperature in the water heater. If the thermostat is incorrectly calibrated, defective or faulty, it may not detect the correct water temperature and prevent the water heater from heating properly.
How to react?
Check the thermostat settings and make sure it’s set to the desired temperature. If the problem persists, the thermostat may need to be replaced.
Scale build-up
Limescale blocks proper operation
Limescale build-up is one of the main causes of water heater malfunctions, particularly in regions with hard water. Limescale can build up on the heating element, reducing its efficiency. This leads to a drop in water temperature and higher energy consumption.
How to react?
If you live in an area with hard water, we recommend installing a water softener to prevent limescale build-up. If limescale is already present, it may be necessary to descale your water heater to remove deposits.
Reservoir problems
Cracks or corrosion in the tank
Over time, your water heater’s tank may corrode or crack, affecting the efficiency of the water heating system. If you notice leaks or signs of rust around the tank, this may indicate that your water heater has suffered internal damage.
How to react?
Once corrosion has occurred, it is often more economical to replace the water heater than to attempt repairs. A professional can inspect the tank and advise you on the best options.
Incorrect settings or electrical faults
Water heater not receiving enough electricity
If you have an electric water heater, it may not heat properly if the electrical circuit is faulty, a circuit breaker has blown or a fuse has blown.
How to react?
Check whether the circuit breaker or fuse has blown, and replace it if necessary. If the problem persists, it may be necessary to call in an electrician to inspect the water heater’s electrical system.
Water pressure problems
Water pressure too low
If the water pressure is too low, this can affect the operation of your water heater, particularly for gas models or storage water heaters. Insufficient pressure can lead to inefficient water heating.
How to react?
Check the water pressure in your pipes and make sure the valves are open. If the pressure remains low, contact a plumber to inspect the plumbing system and solve the problem.
