Hi, Just moved into a house with a Vaillant EcoFit Pure 835 boiler that is 3-4 years old but the previous owner did not bother to register with Vaillant, so Vaillant says its not under warranty.
Apart from a leaky PRV that I noticed on the outside valve that is causing me regular pressure drop, I've noticed that despite setting the CH to 60 degrees on the boiler's control panel, the boiler heats to 75 degrees with the radiator LED blinking. The DHW is set to 50 degrees but I am pretty sure the output from boiler is much higher than that.
Can someone please clarify what is happening here and how can this be fixed?
Many thanks in advance.
