What's wrong with your hot water?

Symptoms
01 — Common problems

What can go wrong with your water heater.

What's usually behind each symptom and what you can check yourself while the technician is on the way. Without touching anything inside.

The water comes out cold or only lukewarm

The most common cause is a burnt-out heating element or a thermostat that no longer cuts out properly. It could also be that the water heater is now too small for your household.

In the meantime · Check whether the water heater's indicator light comes on. If it never comes on, tell the technician.

It takes longer and longer to heat up

Limescale builds up on the heating element and at the bottom of the tank, so the water heater needs more time and more electricity to heat the same amount.

In the meantime · Note how many litres it holds (it's on the label) and how many people live in your home.

It drips or there's water underneath

If it drips from the safety valve while it's heating, that can be normal; if the water is coming from the tank itself, it usually means it's corroded inside.

In the meantime · Put a bucket underneath and, if the dripping doesn't stop, close the water heater's stopcock.

The power trips when you switch it on

It's usually a heating element with an earth leakage or damp in the connections. It's best not to keep resetting the trip switch (RCD) again and again.

In the meantime · Leave the water heater switched off at its own switch, or unplugged, until the technician has seen it.

It makes noise when it's heating

Clicking and bubbling sounds are usually limescale at the bottom of the tank. It isn't dangerous, but it means the water heater is working harder than it should.

In the meantime · Notice whether the noise gets worse over the days; it helps decide whether it's worth repairing.

It's old and you want to replace it

When a water heater starts failing often, it's usually worth replacing it with one of the right capacity for your home.

In the meantime · Take a photo of the water heater's label and of the space where it hangs.

04 — Questions

Questions about water heaters.

Q.01

What size of water heater do I need?

It depends on how many people live in your home and how you use hot water. The professional recommends the capacity after looking at your case.

Q.02

How long does an electric water heater last?

Between 8 and 12 years, depending on how hard the water is and how much it's used. By that age it has paid for itself: if it starts failing often, the usual thing is to replace it.
