What changes a Thermia repair bill
- Brand tier — This factor rests on a single item and is deliberately not passed through as calculated. The only comparable Thermia main board observed at jsenergi.eu is 'Main card Kretskort' at EUR 512.09 -- a raw ratio of 0.64 against EUR 805.18, below the 0.80 scale floor. Reported at 0.85, closer to the baseline than the single observation, because one board is not a whole-brand basket. The shop's manufacturer filter shows 22 Thermia items overall.
- 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 — Most Thermia repairs are a professional job — this brand's parts and diagnostics usually need a qualified technician.
