More info on the maintenance of your heating system

Are you new in Brussels ? As an expatriate, navigating the regulations surrounding heating system maintenance might be unfamiliar territory for you. Don't worry! Here's a comprehensive guide to help you understand your obligations.

Why maintain your heating system?

The government mandates periodic inspections for several important reasons:

  • improve energy efficiency: a boiler and a heater need energy to work, whether it is fuel, wood or gas, it leaves combustion waste which may interfere with a well-functioning system.
  • ensure your security: those combustion wastes may endanger the security of the member in your household, for example, by producing carbon monoxide.
  • reduce air pollution: a clean heating system produces less carbon, therefore, less pollution.

How often should the maintenance happen?

It depends on the Region where you live, but also on the energy you use to heat your house.

In Brussels, gas heaters and boilers must be inspected once every two years while liquid (fuels) and solid (wood) need the visit of an expert once a year.

Who can provide this service?

In order to be considered as valid, the maintenance has to be carried by a professional heating engineer. Moreover, the expert needs some certifications (EPB, GI, GII or L for gas and a regional licence for fuel)

What kind of heating system would suit you?

First of all, the choice of your next heating system will depend on several factors such as the initial installation cost, but also ongoing maintenance, energy efficiency as well as the price for the fuel or other energy source used to operate the system.

  • In the vast majority of the cases, an engineer will advise you a condensing boiler. It uses the exhaust gases before they are vented outside during the combustion process. It means you can benefit from an efficiency exceeding 100%.
  • Wood-burning stove uses wood as a fuel source to produce heat, which is then distributed throughout the home through natural convection or a fan.
  • Solar panels are also an interesting option. They may have higher upfront installation costs but can provide long-term savings on energy bills.
  • In contrast, electric baseboard heating systems do not cost much at the beginning, but are far more expensive to operate over time due to the high cost of electricity.

Do not forget the maintenance of your boiler

In Belgium, there are a few rules to follow in order to make sure your entire heating system comply with the legal standards. These often have ecological and safety goals. The frequency of the controls depends on the type of energy you use: fuel and wood require a visit per year while gas should be inspected once every two years. This difference is due to the fact that the combustion of solids and liquids create more waste, which may result in a fire or other kinds of problems (such as carbon monoxide leaks) if the burner is never cleaned. All the heating engineers who intervene must be certified by Cerga. This is a government-registration that prove the competences of your specialist and that the maintenance will be legally approved by the authorities.

A few tips to control your heating system

Depending on your habits, your use of heating and hot water may represent half of your energy spendings. If you want to reduce the bill, there are a few things you can do:

  • Use a room thermostat: it will help you have a better control on the temperature in every room of your house or apartment. For example, your bedroom has enough with only 18°C while a living room may need up to 21°C. The thermostat will also stop the heating system once the temperature is okay, therefore using less gas or fuel.
  • Turn off the radiator during the night: either you don't use the room that will be heated, either your bedsheets are enough to keep you warm.
  • Use a programmer or a smart system: you can decide what time the heating will turn on and off, for example, just a few minutes before you come home after your working day.
  • Do not forget to ventilate: it is a common misconception to think that you need to keep the heat inside at all costs. A home needs an air flow to get rid of condensation. If you skip this, you could see moisture appear which is dangerous for your health. Moreover, it expels cooking odours and inner pollution. Also note that a humid atmosphere is harder to heat than a dry one.
  • Arrange the disposition of your furniture and decoration: avoid placing a cabinet or a couch in front of your heater, it would block the air flow and, as a result, the heat propagation inside the room. If you have curtains, use them to keep the warm inside as soon as you don't need the natural light anymore. Put rugs on the ground, etc.
  • Make a quick check of your radiators once in a while in order to know if your material is still working as it should. If not, you can call a heating engineer to have your maintenance done.
