How do brand & quality tier change the parts cost?
Brand and tier adjust the parts portion only — never labour. Value brands such as AWB and Agpo Ferroli carry the cheapest, most widely stocked parts; Intergas, Remeha, Nefit and Vaillant form the core of the Dutch boiler market, while ATAG's parts run clearly dearer. Itho Daalderop, Orcon, Brink and Zehnder are the nameplates on Dutch ventilation and heat-recovery (WTW) units, and Daikin, Mitsubishi Electric, Panasonic, LG and Nibe cover heat pumps and split air conditioning — where the priciest boards in this set sit. Pick a tier in the calculator for a class-typical estimate, or a specific Dutch brand to override it.
| Brand | Parts factor | Basis |
|---|---|---|
| Basic tier parts ×0.85 | ||
| AWB | ×0.85 | Parts ×0.85 (AWB is the Dutch brand of the Vaillant Group and is found mainly in older ThermoMaster and ThermoElegance boilers. Its control boards and burner control units cost EUR 119.79 to EUR 168.19 including VAT, with roughly EUR 142 as the midpoint, against some EUR 188 for the benchmark brand. The fans are cheap too, at EUR 90.75 to EUR 127.05. An electronics repair on an AWB therefore usually comes out below the benchmark. Do note: AWB and Vaillant share the parts catalogue of the same group. The SYMSI7.0 burner control unit, article number 2000802734, is listed at EUR 156.09 under both brands; the difference between the two brands in this list comes from the models the webshop shows per brand, not from a price difference on that shared part.) |
| Agpo Ferroli | ×0.85 | Parts ×0.85 (Agpo Ferroli is found in many older Dutch boilers, such as the Econpact and the Ultima. Individual burner control units for these appliances are offered in the trade from EUR 25.00 up to EUR 149.95, where the same kind of part costs around EUR 188 for the benchmark brand. Please note: none of the burner control units on the page reviewed is marked as new, so these are presumably take-out or reconditioned parts, and what you pay depends heavily on the condition of the part. This is also work on a gas-fired appliance: since 1 April 2023 only a company holding a valid CO-vrijcertificaat (Dutch carbon-monoxide safety certification) may carry out that work, and the consumer is required to engage such a company. On balance, Agpo Ferroli is cheaper than the benchmark on parts.) |
| Mid-range tier parts ×1.05 | ||
| Intergas | ×1 | Baseline — no parts adjustment |
| Remeha | ×1 | Baseline — no parts adjustment |
| Nefit (Bosch) | ×0.9 | Parts ×0.9 (Nefit, these days Nefit Bosch, has a broad and readily available parts range at Dutch webshops. Its burner control units run from EUR 119.00 to EUR 205.70 including VAT, with roughly EUR 151 as the midpoint, so about twenty percent below the benchmark of EUR 188. Against that, a Nefit fan or gas valve block sits at or above the market level: EUR 225.00 for a fan box and EUR 182.62 for a gas valve block. That is why the brand sits just below the benchmark and not far below it.) |
| Vaillant | ×1.05 | Parts ×1.05 (Vaillant is a German boiler brand found in Dutch homes, and its parts are widely available. The burner control unit and the main board cost EUR 156.09 to EUR 189.00 including VAT here, which puts them almost exactly on the benchmark of EUR 188. The difference is in the fans: those for the heavier hrEXCLUSIEF appliances cost EUR 301.29 and EUR 349.69, well above what a fan costs for most other brands. That makes a repair on a Vaillant come out on average just a little above the benchmark. AWB is the Dutch brand of the same group: the SYMSI7.0 burner control unit, article number 2000802734, is listed at EUR 156.09 under both brands.) |
| Itho Daalderop | ×0.85 | Parts ×0.85 (In the Netherlands Itho Daalderop is above all the brand on the mechanical ventilation box and the heat-recovery unit, and on central-heating and hot-water appliances besides. On the ventilation side the parts are cheap: a service module or control board costs EUR 59.29 to EUR 139.00 including VAT, with EUR 119.00 as the midpoint, well below the benchmark of EUR 188. Because that is the part this brand is in practice most often repaired on, Itho Daalderop sits below the benchmark. On the central-heating side it runs the other way: there the burner control unit is listed at EUR 471.00, so that side of the brand is clearly dearer than this figure suggests. Work on such a gas-fired appliance may only be done by a company holding a valid CO-vrijcertificaat (Dutch carbon-monoxide safety certification).) |
| Inventum | ×1.05 | Parts ×1.05 (Inventum is a Dutch brand of, among other things, air heating, ventilation and hot-water appliances, found in homes with an Ecolution or Modul Air installation. The fans offered with a price in the Netherlands cost EUR 225.00 and EUR 240.79 including VAT. That is at the top end of what a fan costs for other brands, where EUR 90 to EUR 156 is usual. Inventum is therefore placed just a little above the benchmark.) |
| Brink | ×1.25 | Parts ×1.25 (Brink Climate Systems, from Staphorst, makes the heat-recovery units fitted in many newly built homes, such as the Renovent and the Flair. The control board for those units costs EUR 484.00 including VAT new, while a comparable control part from the benchmark brand costs around EUR 188. For anyone wanting to keep the bill down there is a lively trade in reconditioned Brink boards, which are offered for a few tens of euros; this is ventilation work and does not fall under the certification requirement that applies to gas appliances. New Brink electronics sit clearly above the benchmark.) |
| Zehnder | ×1.2 | Parts ×1.2 (Zehnder, long known in the Netherlands under the name J.E. Stork Air, supplies the ComfoAir heat-recovery units that handle the ventilation in many homes. The control board for the ComfoAir Q costs EUR 332.75 including VAT, against roughly EUR 188 for the comparable control part from the benchmark brand. This brand's electronics therefore sit above the benchmark.) |
| Orcon | ×1.1 | Parts ×1.1 (Orcon, also known under the names Ubbink and Rucon, makes the ventilation and heat-recovery units many Dutch homes have. The main circuit board for an HRC unit costs EUR 249.00 and the complete fan module EUR 390.00, while the control part from the benchmark brand costs roughly EUR 188. Smaller boards, such as the one for the humidity sensor, are cheap by contrast at EUR 45.98. On average that puts Orcon slightly above the benchmark.) |
| Duco | ×1.2 | Parts ×1.2 (Duco supplies the DucoBox ventilation units that are widely fitted in Dutch new-build and renovation work. The parts are on the expensive side: a complete fan box costs EUR 988.00, a separate fan EUR 295.00 and a humidity sensor EUR 154.19, while the comparable control part from the benchmark brand costs around EUR 188. Repairs on this brand therefore usually come out above the benchmark.) |
| LG | ×1 | Baseline — no parts adjustment |
| Bosch | ×1.05 | Parts ×1.05 (In the Netherlands Bosch is the brand name on the central-heating boilers of the HRS and HRC series and on the Compress heat pumps; many Dutch boilers from the same group carry the name Nefit. At a Dutch spare-parts webshop the burner control unit for a Bosch boiler costs EUR 185.00 including VAT, virtually the same as the roughly EUR 188 of the benchmark brand. The fans cost EUR 72.60 to EUR 170.01, with EUR 170.00 as the most common price, a little above the EUR 90 to EUR 156 of the benchmark brand. That places Bosch just above the benchmark. This figure is about the parts of the gas boiler: no price for a circuit board for a Compress heat pump was found for the Netherlands. Work on the burner control unit of a gas-fired appliance may only be done by a company holding a valid CO-vrijcertificaat (Dutch carbon-monoxide safety certification).) |
| Samsung | ×1.05 | Parts ×1.05 (tier median (parts pricing not separately sourced) — Samsung supplies split air conditioners and EHS heat pumps that are fitted in the Netherlands. Only small parts for this brand can be found with a price in the Netherlands, such as a motor at EUR 130.29, a filter at EUR 31.68 and a board relay at EUR 12.63. No price for a circuit board or a control part was found for the Netherlands, so no price level of its own can be established for this brand: the figure above is the midpoint of the other brands in the same price class and not a measurement of Samsung parts. The webshop does not state whether these prices include or exclude VAT.) |
| Premium tier parts ×1.15 | ||
| ATAG | ×1.35 | Parts ×1.35 (ATAG, from Lichtenvoorde, has the most expensive central-heating parts measured in this list. The E-series control unit is listed by two Dutch webshops at EUR 464.82 and EUR 527.56 including VAT, against roughly EUR 188 for the same kind of part from the benchmark brand. That is more than twice as much. The fans, at EUR 151.25 to EUR 181.50, are also at the top end of the market. ATAG is therefore placed at the upper limit of this list.) |
| Daikin | ×1.1 | Parts ×1.1 (Daikin is one of the brands Dutch climate webshops stock as standard for air conditioners and air-to-water heat pumps. The parts offered with a price in the Netherlands are for the most part ordinarily priced: a fan motor costs EUR 157.85, a cross-flow fan EUR 137.00 and a fan EUR 114.00 including VAT, against EUR 90 to EUR 156 for a fan from the central-heating brands in this list. The coil for a motorised valve, at EUR 215.00, is dearer than the EUR 128.00 to EUR 129.95 that a three-way valve motor costs on a central-heating boiler. No price for a circuit board for a Daikin appliance was found for the Netherlands. Daikin is therefore placed slightly above the benchmark of EUR 188 and not at the upper limit of this list.) |
| Mitsubishi Electric | ×1.15 | Parts ×1.15 (Mitsubishi Electric supplies split air conditioners and heat pumps that are fitted in Dutch homes. Few parts for this brand can be found with a price in the Netherlands: a wired controller costs EUR 245.00 including VAT, a bottom louvre EUR 144.00 and a handle EUR 112.00. That controller is dearer than the roughly EUR 188 the control part from the benchmark brand costs; the other two parts are not. No price for a circuit board for this brand was found for the Netherlands. Mitsubishi Electric therefore sits above the benchmark, but not at the upper limit of this list.) |
| Panasonic | ×1.1 | Parts ×1.1 (With the Aquarea heat pumps and the split air conditioners, Panasonic supplies climate appliances that are fitted in the Netherlands. At a Dutch spare-parts webshop the parts for these appliances cost EUR 36.07 to EUR 238.93: a coil costs EUR 111.13 and an evaporator EUR 238.93. One price for a circuit board was found in the Netherlands, EUR 276.00 at a wholesaler for installers. That is a gross list price from a trade catalogue and not a consumer price, but either way it sits above the roughly EUR 188 of the benchmark brand. Panasonic is therefore placed slightly above the benchmark. Neither webshop states whether its prices include or exclude VAT.) |
| Nibe | ×1.2 | Parts ×1.2 (Nibe supplies ground-source and air-to-water heat pumps that are fitted in Dutch homes. Few parts for this brand can be found with a price in the Netherlands: a complete cooling module costs EUR 2,999.00 including VAT and a set with an RF receiver and transmitter EUR 289.00. That set is dearer than the roughly EUR 188 the control part of a central-heating boiler costs, and a cooling module of that kind is a complete assembly rather than an individual repair part. No price for a circuit board for a Nibe heat pump was found for the Netherlands. Nibe therefore sits above the benchmark, but not at the upper limit of this list.) |
