Is maintenance mandatory?
For rental or warranty sometimes yes; we in any case recommend annual maintenance.
For private homeowners, CV-ketel maintenance is not always legally mandatory, but strongly recommended — for safety, efficiency and a longer lifespan. For landlords and under some warranty terms, periodic maintenance may be required. An annual check by a certified installer spots wear and safety risks early. Klimaat 040 handles CV-ketel maintenance in and around Eindhoven from around €79, for all brands.
