What does that really meanr a boiler manufacturer such as Wocester Bosch, Baxi, Glowworm etc.
Below is an example:
Gas Valves on most British Gas Boilers are made by Honeywell, Sit, White Rogers etc. This means that these manufacturers are the OEM for the Boiler Manufacturers, so as long as the original part is purchased (Honeywell, Sit, White Rogers) from the OEM it can be sold as an original OEM product.
OEM parts are also referred to as After Market Parts.
