Shipping across the EU
ACV parts ship by PostNL parcel from our warehouse in Alblasserdam near Rotterdam (the Netherlands) across the EU. Shipping costs €9.95 per order to Austria, Denmark, Italy, Spain and Sweden and €12.95 to the other EU countries, VAT included. Free delivery from €199. In-stock items usually arrive within 3–5 working days, made-to-order items within 5–7 working days (a longer lead time is shown on the product page). You pay by credit card, Apple Pay, Pay by Bank, PayPal or Klarna.
To EU countries outside the Netherlands and Belgium we only ship what can go by parcel post: genuine spare parts and small items (thermostats, taps, filters, sensors, pumps, circuit boards and the like), plus electric heating up to 32 kg. Complete appliances — central heating boilers, heat pumps, storage and heat pump water heaters, radiators, split air conditioners — and home batteries are currently not shipped there; compact kitchen water heaters are. Customers in the Netherlands, Belgium, Germany and France have their own sites: instalpunt.nl, instalpunt.be, instalpunt.de and instalpunt.fr.

Frequently asked questions
I live outside the Netherlands. Can I order ACV parts here?
Yes, from any EU member state. Parts and small items travel by tracked PostNL parcel: €9.95 per order to Austria, Denmark, Italy, Spain and Sweden, €12.95 to the other EU countries, free from €199. Complete appliances are not shipped outside the Netherlands and Belgium — see Shipping.
My ACV appliance was installed in another country. Are the parts the same?
Mostly. ACV uses the same manufacturer part numbers across Europe; what changes between countries is the model name on the casing, sometimes the gas type, and the language on the labels. Go by the series on the rating plate and the number on the old part, not by the marketing name.
How do I make sure I order the right ACV part?
Find the series and model on the rating plate, open that series in the catalogue and match the position number in the exploded view. Or e-mail a photo of the rating plate and the old part to info@instalpunt.com — we reply in English with the part number.
Are these original ACV parts or copies?
Original manufacturer parts. All 189 items carry the ACV part number, so your engineer can check it is the exact part they would have ordered.
What if it turns out to be the wrong part?
EU consumers have fourteen days to withdraw. Unused parts go back in their packaging; items ordered specially from the manufacturer and parts that have been fitted are the exceptions. Details on the returns page.
