Frequently asked questions

I live outside the Netherlands. Can I order A.O. Smith 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 A.O. Smith appliance was installed in another country. Are the parts the same?

Mostly. A.O. Smith 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 A.O. Smith 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 A.O. Smith parts or copies?

Original manufacturer parts. All 473 items carry the A.O. Smith 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.
