How do brand and quality tier change the repair 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 for a class-typical estimate, or a specific Spanish brand to override it.

Boiler no heat / not firing up: what usually causes it? Estimated
-
Replacing the circulation pump
Pro recommended€230–€470
The condensing boiler with radiators is the dominant heating system in northern and central Spain, and the circulation pump is its star fault: the boiler fires, the water heats, but nothing reaches the radiators. The price moves with the brand — Junkers or Saunier Duval pumps are appreciably dearer than a compatible one — and with how accessible it is inside the appliance. Work for a registered gas installation company, because the appliance has to be partly drained down and then recommissioned as a gas appliance.
-
Replacing the room thermostat
Pro recommended€60–€180
Many 'I have no heating' calls end in a thermostat that is not sending the demand: flat batteries, a dirty contact or a badly set programme. It is the first thing the technician checks because it is the cheapest to rule out. The cost is set by the device fitted, from a €20 analogue unit up to a modulating one linked to the boiler over a communication bus.

How much is a service-call fee for boiler repair?
Most Spanish companies charge a call-out / diagnostic fee of €36–€97, often credited toward the repair if you go ahead. It is separate from the repair totals above. Spain's standard 21% VAT (IVA) applies to heating and cooling repair services, and consumer prices are shown VAT-inclusive. A repair carried out in a dwelling can fall to the 10% reduced rate (Spanish VAT Act art. 91.Uno.2.10º) when three conditions hold at once: the customer is a private individual, the dwelling was completed more than two years ago, and the materials supplied by the firm are under 40% of the tax base. Labour-heavy jobs with little material often meet all three, so 21% is the standard rate but not always the effective rate on the invoice — treat it as a ceiling, not a guaranteed add-on.
Is it worth repairing a boiler, or should you replace it?
A common rule of thumb: if the repair cost exceeds roughly half the price of a comparable new unit — or the appliance is past ~8 years for a boiler — replacement is often the better value. The calculator's localized totals give you the number to weigh against a new-unit quote.
