Our Vaillant ecoTEC plus boiler was installed in March 2012 by an accredited installer. About a year later, we noticed that the pressure in the central heating circuit was creeping up requiring us to bleed the system quite often to reduce the pressure. No solution was found.
In May 2014, another engineer was advised by Vaillant to replace the 'Changeover valve' (£170). With installation and testing this cost us £432.40 in total, but the problem returned after only a few months.
Vaillant advises "I am very sorry to learn of the problems that you have experienced. Please be assured that we manufacture some of the most reliable and efficient product on the market and the model that you have selected has proven very reliable in the field. Your appliance was supplied with a two year guarantee supported by our Group Service organisation in order to protect our customers against manufacturing defects. Outside of this period, our customers are offered the option of either taking out an extended warranty policy or enlisting the services of our, or a local engineer, on a chargeable basis as and when is necessary." Annoyingly, we were never made aware of this option by the installer or later.
If Vaillant are so confident that their boilers are "some of the most reliable and efficient product on the market" it is somewhat surprising that they only offer a basic 2 year warranty. This video shows the weekly procedure to reduce the excess pressure in the circuit.
