I've got a 3 yr old combi Vaillant TurboMAX plus 824E and i've got a problem with the HW temp.
During the last few weeks i've noticed that when the CH is on, the HW isn't working properly. The HW comes thru at the right pressure, but the temp isn't warm enough - it's not freezing cold but it's prob at approx 20% temp of what it should be.
But then say for eg, if the CH is off, the HW is always ok. I've checked for leaks etc (of which there aren't any), there's no error codes at all & the pressure is at 1.3b & is ok.
Like I say everythin seems ok, until the CH is on & only then we seem to be getting the problem with the HW every now & again. But i want to resolve the problem before it gets serious, any advice would be welcome + would anyone recommend a service by a CORGI plumber for eg?
Thanks to all in advance.
