How to protect your water heater from limescale?

Limescale is undoubtedly the worst enemy of your household appliances. It affects both their performance and their lifespan.

The harder your water is, the more likely you will have significant limescale deposits, which will prematurely damage your equipment. Fortunately, there are solutions to mitigate the adverse effects on your water heater.

Descaling your water heater

Descaling your water heater should be done on average every five years. In short, it consists of emptying the tank, opening the tank to clean it and then refitting the tank. This process will ensure that the water heater works properly.

Install a water softener to remove limescale

If your water is very hard, it may be worth installing a water softener to remove limescale from your pipes permanently. It will protect your water heater. A water softener is a device that eliminates limescale through a chemical process. It is often installed near your water supply.

Installing an anti-limescale filter

The anti-limescale filter has a cartridge that contains polyphosphates (in the form of crystals or beads). The water will flow through it, and the limescale will remain suspended in the water instead of settling in the pipes. One filter is sufficient to treat your entire water system.

Depending on the hardness of your water, the filter should be replaced more or less often.
This type of device must be maintained regularly.

Tips to limit the scaling of your water heater

To limit the scaling of your water heater, you should set your thermostat to heat it to a temperature slightly above 55°C.
