How do brand & quality tier change the parts cost?
Brand and tier adjust the parts portion only — never labour. Value brands — Cointra, Ferroli, Fagor and Daitsu — carry the cheapest, most widely stocked parts; Baxi (Roca), Junkers Bosch, Saunier Duval and Ariston form the mainstream core of the Spanish boiler market, alongside LG, Samsung, Fujitsu (General) and Haier on the air-conditioning side; premium makers — Vaillant and Viessmann in boilers and air-to-water heat pumps, and Daikin, Panasonic, Hitachi and Mitsubishi Electric in air conditioning and heat pumps — use higher-grade components, often sold through the manufacturer's official channel (piezas de origen). Pick a tier in the calculator for a class-typical estimate, or a specific Spanish brand to override it.

Is it worth repairing a thermostat & controls?
If the repair quote exceeds roughly half the price of a comparable new thermostat & controls — or the unit is well past its typical service life — replacement is often the better value. Localize the repair range above first, then compare.
