heating always on in warm start mode

[petejaniec]

hi
could anyone advise so i can then get someone in please
ecotec . when hotwater is set to 80 percent on knob its fine and rads dont get hot
when i turn knob to max and boiler is warmstart mode with c the heating just stays on constantly and hotwater is still warm. i was told it wasnt whats called a diverter valve because the water is hot and not luke warm and in warmstart mode again water is warm not lukewarm, help please many thanks

I wonder why you want to put the knobs into a non usual operating position.

But it sounds as if the diverter valve may be jamming or not moving the full travel.

The warmstart function on the Vailant ecotec boiler is designed to give you immediate hot water, and it does it by switching on the boiler to keep the water hot. It just wastes gas. Switch it off, and it'll just take a little longer to heat the water from scratch. When you say the heating stay on, do you mean the boiler seems to run, but the rads aren't actually getting hot.

need it rammed up otherwise shower and bath is not that warm. dont mind having warmstart but not when heating comes on. rads are hot yes when in preheat mode! as said it cant be diverter valve as when hotwater is on with no prewarm heating reamins as it should be off. bizzare . only comes on and stays on when prewarm on

Sounds like a faulty boiler module. I almost get the impression they're saying it's supposed to work that way, but I can' see why.
