Why replace your old gas appliances?

The older your appliance is, the more cost-effective it will be to replace it. This is because new gas appliances are much more energy efficient and will gradually pay for themselves.

In addition, many old appliances are incompatible with the new rich gas, and there are currently grants for their replacement. So why wait?

What equipment is affected?

All new appliances that run on natural gas: boilers, water heaters, convectors and built-in fireplaces*.

Appliances powered by gas cylinders (butane, propane) are not affected.

*See general conditions on the website (in French)

Replacement = up to 30% savings!

The efficiency of modern gas appliances is such that they can save you up to 30% on your gas bill! This is why the cost of purchasing a new appliance will be written off over the long term, more or less quickly depending on the scenario.

In the case of a boiler, investment in a new central heating boiler pays for itself as soon as it is over 20 years old. It can easily save you 25% on your energy consumption.

As a general rule, the older an appliance is, the more expensive it is to use and the more likely it is to pose a safety risk (leaks, fires, etc.). If your appliance is at the end of its life, you might as well replace it as soon as possible to start saving on your energy consumption now.

Avoid the cost of switching to rich gas

If your gas appliances are getting old, this is the best time to decide to invest in new ones. Remember: since September 2020, gas has been changing in Brussels.

You are responsible for the mandatory checking of all your gas appliances by a certified technician, as well their regulatory compliance. Therefore, it is probably not necessary to incur all these costs to extend the life of an old, energy-intensive appliance when you will have to replace it anyway in years to come.

If you are not replacing your old gas appliances, there are two possible scenarios:

Scenario 1: Your appliance is incompatible

You'll have to throw it away! In theory , this applies to all appliances dating from before 1978, as well as those purchased abroad that are incompatible with rich gas.

Scenario 2: your appliance has to be adapted

One out of five appliances dating from 1978 onwards have to be adapted in order to function properly. The rule is that the older they are, the more likely it is that an adjustment will have to be made by an authorised technician.
