What changes a Bulex repair bill
- Brand tier — Bulex is the Belgian boiler badge of the Vaillant group and is fitted in a great many Belgian homes; its spare parts are in stock at every Belgian parts supplier, which is why this brand carries the reference price in this guide. An original main control board for a Bulex wall-hung gas boiler costs between EUR 361.94 and EUR 464.05 incl. VAT at a Belgian parts supplier, with EUR 396.76 as the mid-point. For older and heavier ranges a board runs up to EUR 1,131.52 at another Belgian supplier. That two suppliers ask exactly the same amount for the same part number (0020037670) shows that this is the going Belgian price level. Anchor entry. Bulex main boards at BekaTech restated on one incl-btw basis (+21%): 0020037670 EUR 299.12 excl = 361.94 incl, S1047000 EUR 327.90 excl = 396.76 incl, 0010028087 EUR 383.51 excl = 464.05 incl; median EUR 396.76 is the anchor for every board ratio in this guide. Cross-shop validation and anchor sensitivity: VEPA lists 0020037670 at EUR 361.94 incl (exact match with the normalised figure) and goegekeurd lists S1047000 at EUR 399.60 incl (0.7% apart), while the goegekeurd Bulex board range spans EUR 312.25-1,131.52 with a median of EUR 529.47, so the chosen anchor lies between the low and the high alternative. Excluded as not main-board class: the three-way-valve board (EUR 82.33) and filter board (EUR 104.37) at goegekeurd. Also observed at BekaTech and used as standing comparators elsewhere in this guide: veiligheidsventiel 3 bar EUR 22.90 excl (= EUR 27.71 incl), expansievat EUR 207.11 excl (= EUR 250.60 incl), driewegklep EUR 98.38 excl (= EUR 119.04 incl).
- Parts vs labour — the brand and tier shift the parts price; labour tracks your area's wage index, not the brand.
- The specific fault — a sensor, seal, or valve is far cheaper than a compressor, motor, or control board.
- DIY vs professional — Some Bulex faults (filters, seals, hoses) are DIY-feasible for confident owners; sealed-system and control-board work is a professional job.
