What changes a Riello repair bill
- Brand tier — Riello is the burner fitted to a great many Belgian oil-fired boilers, even when the boiler itself carries another badge. At a Belgian supplier an original oil pump costs EUR 174.06 to EUR 397.65 incl. VAT, with EUR 214.73 as the mid-point, and the small parts cost little: a solenoid valve EUR 229.97, a solenoid coil EUR 20.59, a pump filter EUR 8.39 and a pump cover gasket EUR 3.30. Burner parts are more simply built than a modulating gas board and therefore cost about half the EUR 396.76 a Belgian supplier asks for the reference board. Basket-derived and floor-clamped. Seven observed oil pumps incl btw: EUR 174.06, 200.74, 214.73, 214.73, 231.22, 266.81, 397.65; median EUR 214.73. The only possible comparison is cross-class against the boiler baseline: 214.73 / 396.76 = 0.541, below the 0.85 floor, so clamped up to 0.85 with the raw reading printed. This pump median is the standing comparator used for De Dietrich, Weishaupt and Elco. Small burner items (magneetklep EUR 229.97, magneetklepkern EUR 46.37, magneetspoel EUR 20.59, pompfilter EUR 8.39, pompdekselpakking EUR 3.30) confirm the level rather than set it. Caldaria applies per-product discounts, so the pump median is a lower bound.
- 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 Riello faults (filters, seals, hoses) are DIY-feasible for confident owners; sealed-system and control-board work is a professional job.
