Water heater servicing in Brussels
Brussels water is hard: without servicing, your water heater scales up, uses more energy and eventually gives up. Our technicians descale it and check the anode and the safety valve, for reliable hot water all year round.

Why service your water heater?
In Brussels, tap water is hard: limescale settles on the heating element and at the bottom of the tank, year after year.
- 01
Lower consumption
A scaled-up heating element heats less well: your water heater runs longer for the same amount of hot water.
- 02
A longer life
The anode protects the tank against corrosion. Replaced in time, it prevents the leak that means changing the whole appliance.
- 03
More safety
The safety valve protects the tank against overpressure. It still has to work: we test it at every service.

What the service includes
- Partial or full draining of the tank, depending on its condition
- Descaling the heating element and removing deposits
- Checking the anode, with a replacement suggested if it's worn
- Testing the safety valve and relief valve
- Checking the thermostat and the set temperature
- Checking the connections and seals
- Checking the power supply (electric water heater)
- Advice on settings to limit limescale and consumption

Which appliance do you have?
The servicing depends on how your hot water is produced. If in doubt, a photo of the appliance is enough for us to point you in the right direction.
Electric water heater
A tank of water heated by an electric element. It's the one that suffers most from limescale.
- Descaling the heating element
- Checking the anode
- Testing the safety valve
Cylinder linked to the boiler
The water in the cylinder is heated by your boiler through a coil. It's serviced like a water heater.
- Checking the anode and the safety valve
- Checking the sensor and the coil
Combi boiler
No storage: the water is heated on demand by the boiler itself.
- Checked during the boiler service
- Descaling the hot water exchanger if needed
Signs your water heater needs a service
- 01
Lukewarm water, or water that cools quickly
The scaled-up heating element can no longer heat the whole tank.
- 02
Kettle-like noises
Crackling or whistling while it heats: limescale is building up at the bottom of the tank.
- 03
Cloudy or rusty water
A possible sign of a worn anode and a tank starting to corrode.
- 04
Safety valve running all the time
A little water while it heats is normal; a constant flow isn't.
- 05
Electricity bill going up
A clogged water heater uses more for the same comfort.
- 06
More than 2 years without a service
With water as hard as in Brussels, a service every 1 to 2 years is generally recommended.

Frequently asked questions
Frequently asked questions about water heater servicing
Can't find your question? Ask it on WhatsApp, with a photo if that helps, or leave your number and we'll call you back.
A gas water heater service costs €129 VAT incl. and an electric water heater service €220 VAT incl.. If a part needs replacing, you get its price before the work.
With Brussels' hard water, a service every 1 to 2 years is generally advised, depending on how much hot water you use.
The anode wears away instead of the tank, protecting it from corrosion. Once it's used up, the tank starts to rust: that's why it's worth checking regularly.
A little water while it heats is normal: it's the water expanding. If it runs all the time, the safety valve is probably faulty and needs replacing.
On average 10 to 15 years, depending on the water quality and the servicing. A water heater that's never descaled in Brussels ages much faster.
For a short absence, just lower the temperature. For a long one, you can switch it off: when you're back, let it heat to at least 60 °C once before using the water.
Yes. No hot water, a leak, a breaker that trips: we come out for repairs 7 days a week, within 24 hours.
