SIEMENS STP23 AC 230V 2-POSITION/PDM ELECTROTHERMAL ACTIVATOR.

This part is based around the diverter valve section. The diverter valve is a directional water mechanism that is only found on a combi boiler, which is designed to allow hot water to be directed to the taps in a hot water system or to the radiators in a central heating system. This is the main difference between a combi boiler and a normal boiler due to the fact that a cylinder is not needed to provide hot water to the central heating system and taps .

We dont have this part listed against any specific appliance present on our website, if you have been told that this is the part you require please contact us.


The SIEMENS STP23 AC 230V 2-POSITION/PDM ELECTROTHERMAL ACTIVATOR is a genuine, brand new Siemens product, covered by a Siemens manufacturer's guarantee.
