Your hot water tank won’t turn on anymore, a few small adjustments and then the hot water will come back in time to enjoy it, that’s a promise. This problem is quite frequent, sometimes you only have to change one part or adjust one component. But which ones ?

Did you know that to reduce the risk of breakdown and to insure yourself in case of a disaster, a hot water tank is serviced annually? That your tank must be emptied every 2 years? That the maintenance of your tank reduces the risk of corrosion?

Your hot water tank no longer lights up, your circuit breaker has blown…
Yes yes, we know, it’s the most common problem, the most surprising and above all the easiest to solve. Your hot water tank must be overheating. If your settings are at maximum, a risk of over-consumption of a hot water tank can cause everything to break down.

Indeed, this over consumption of electricity can lead to overvoltage and block the resistance. An effective way to avoid this kind of unpleasant surprise is to reduce the heating power. In addition, you can check the correct setting of your hot water tank in order to get the best possible performance.

If the problem persists, then the problem is not the energy consumption but the beginning of a leak. It may also be one of the components to be replaced (safety group, thermostat or electric resistance).

The thermostat is incorrectly set
When the hot water tank is heated more than necessary or to the maximum, the thermostat is set incorrectly.

It is preferable to lower the thermostat setting. Using the thermostat too much for heating water can damage it. If your thermostat is not working properly, you should check its settings. However, if it no longer works and your water no longer heats up, it will have to be replaced.

In addition, an accumulation of a deposit at the bottom of the tank can cause the thermostat to overheat. Over time, nearly 15L of limestone, sand and gravel prevents the water from circulating properly.

This is why it is necessary to drain the tank every two years. This allows the components to be checked and descaled.

The electrical resistance is scaled
Limescale is the main cause of failure or leakage for a hot water tank. In addition, maintenance is essential, especially in areas where there is a high level of limescale in the water.

For example, too large a deposit at the bottom of the tank can block the electrical resistance. Indeed, the scale blocks the resistance, which causes overheating and may damage the thermostat as well as break everything.
