Ideally with three details: the brand of the appliance, the exact type or model number and, if legible, the article or manufacturer number of the old part. These are on the rating plate. Then search our spare parts catalogue by brand, appliance or part number; the product page shows which appliances the part fits. If in doubt, check with the manufacturer or your installer before ordering.

On a gas boiler usually underneath or behind the front flap; on Intergas and Remeha often underneath, on Nefit Bosch behind the control flap or on the side. On a heat pump it is on both the indoor and the outdoor unit; on a ventilation unit behind the front panel or on the side of the casing. Photograph the brand, type, serial number and any product codes. Do not remove covers if that is not safe or would give access to gas or live parts.

No. One brand has several series, years and versions with different parts. A pump, sensor or PCB from Intergas, Remeha, Nefit Bosch, Vaillant or ATAG can look the same and still have a different connection, software version or dimensions. Always order on the basis of the full appliance type and, where possible, the part number of the old part.

Not every part. Work on gas-carrying parts, the burner, gas valve, heat exchanger, flue and recommissioning must be done by a qualified gas engineer. Outside the sealed combustion section, a competent DIYer can often replace a siphon, room thermostat, thermostatic radiator head or ventilation filter; always follow your appliance’s manual. We will tell you honestly when an engineer is needed.

No. Instalpunt supplies parts within the EU but does not install them. Please use an installer near you.

Our products are covered by the statutory guarantee and, where applicable, by the manufacturer’s warranty. Duration and conditions vary by product. More on our warranty page.

An original part is made by or officially supplied for the manufacturer of your appliance and carries its part number. An alternative part comes from another manufacturer and is offered as compatible. For technical installations we recommend the original when the manufacturer requires it, when the part is safety-related (gas valve, burner, ionisation, flue parts, PCB) or when compatibility is not certain.

Yes. For stock items you have a 14-day right of withdrawal after receipt; notify us within that period, then you have another 14 days to send the product back, complete and if possible in its original packaging. Return shipping is at your expense; we refund the order amount including delivery costs within 14 days. See Returns.

To a limited extent. You may examine a product as you would in a shop. If a part has already been fitted, connected, used or damaged, a reduction in value may be charged. So only fit a part after checking the type, connection and application.

The water pressure (cold, between 1.5 and 2 bar), the thermostat (batteries, setting, programme), whether the gas valve is open and the appliance has power, and whether the siphon or condensate drain is blocked. One reset is fine; if the code returns quickly, do not keep resetting. Anything behind the casing in the combustion section is work for a qualified engineer.

Enter it in the search box of the spare parts catalogue; we search by manufacturer number, article number and EAN. If nothing comes up, the number may have been superseded. Send us a photo of the number and of the rating plate and we will look up the successor for you.
