Homeowners don't know when their heating boiler needs replacement, leading to unexpected breakdowns and expensive emergency repairs

Dutch homeowners actively search for guidance on CV-ketel (central heating boiler) replacement timing because they lack clear indicators of when replacement is necessary. Current solutions fail because boiler maintenance is opaque—homeowners either wait for catastrophic failure (costly emergency repairs) or replace functioning units prematurely (wasted money). This creates anxiety about timing and budget unpredictability.
