How do brand and quality tier change the repair cost?
Brand and tier adjust the parts portion only — never labour. NIBE of Markaryd is the Swedish volume maker of ground-source, air-to-water and exhaust-air heat pumps, and its board prices set the 1.0 reference line every other brand is measured against. Panasonic and Samsung carry the lowest parts prices, followed by Thermia, Värmebaronen and Bosch. Fujitsu and Mitsubishi Electric sit highest, followed by CTC, Daikin and Vaillant, with Toshiba, Mitsubishi Heavy Industries, IVT and LG moderately above the line. On the ventilation side Systemair, Flexit and Östberg sit at the reference level and Swegon above it. ComfortZone and Energy Save have no published Swedish board price and are left at the reference level; EVI Heat, Viessmann and Swegon have none either and are set to the premium band median. The factors below are parts prices relative to the reference line — not a quality, reliability or market-share ranking — and they do not track the price tier: premium-tier Panasonic sits lowest because a split-AC board is a physically smaller item than a hydronic main board. Pick a tier for a class-typical estimate, or a specific Swedish brand to override it.

Boiler leaking water: what usually causes it? Estimated
-
Sealing a leaking joint on the boiler or the radiator circuit
Pro recommended2 500–5 000 kr
The most common and cheapest measure for a dripping boiler is sealing a single joint: SEK 2,500–5,000 before ROT, roughly SEK 2,000–3,800 after the deduction. It applies to visible joints in the boiler room, at the pump or at a radiator connection. Pipework on tap-water and heating systems follows the Säker Vatten industry rules, and an installation that departs from them can cause problems with the household insurance in the event of a future water escape — that is the reason this is not a do-it-yourself job even when the leak looks trivial.

Replacing a short length of pipe or a connection at the boiler after a leak
Pro recommended4 000–9 000 kr
If the leak is in the pipe itself and not in the joint, a short length of pipe under a metre is replaced, which costs SEK 4,000–9,000 before ROT and about SEK 3,200–7,000 after. The spread is driven by access: a freely exposed length of pipe in the boiler room sits in the lower part, a pipe that has to be uncovered behind panelling in the upper. The median hourly rate for Swedish plumbers is SEK 725 and the hourly rate including VAT SEK 1,125–1,375 during normal weekday hours. If the job is done out of hours, a surcharge of SEK 1,200–1,800 is added.

How much is a service-call fee for boiler repair?
Most Swedish companies charge a call-out / diagnostic fee of 450–900 kr, often credited toward the repair if you go ahead. It is separate from the repair totals above. VAT (moms, 25%) may or may not be included: heating, cooling and ventilation work sits on the standard rate, and Sweden's reduced repair rate applies to an enumerated goods list (bicycles, shoes, leather goods, clothing and household linen) that does not reach heat pumps, boilers or ventilation units. Many small firms and sole traders fall under the small-business VAT exemption (turnover under SEK 120,000 per year, since 2025) and charge no VAT — so treat 25% as a ceiling, not a guaranteed add-on. The ROT deduction is not a VAT cut but a tax reduction on the labour cost (30%, up to an annual cap per person), and it never applies to materials, the equipment itself or the call-out fee. Prices here are shown before ROT.
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.
