Unlike gas boilers, heating oil boilers are subject to annual mandatory maintenance in Brussels, rather than every two years - burning heating oil generates more soot and deposits, which justifies more frequent inspection.
What the annual maintenance covers
Beyond cleaning the burner and heat exchanger, the maintenance includes a combustion check and, a point often overlooked, an inspection of the condition of the tank and its fittings: a heating oil leak is a costly environmental incident that is largely avoidable through regular inspection.
Planning ahead
The Brussels-Capital Region is gradually tightening the conditions for installing new heating oil boilers, with a clear trend towards favouring gas and renewable solutions for replacements. While this doesn't require the immediate replacement of an existing, well-maintained appliance, it's a factor to bear in mind as soon as a major breakdown or an ageing tank raises the question of replacement.
We support our heating oil customers both with routine maintenance and with assessing a transition to gas or a heat pump when the time comes.
