Question about Heating & Cooling

Open Question

I have a vaillant VP4-ZE 15 PC water heating system and I have just moved into a property and there are no instructions for the heating system. I cannot work out how to use the timer switch for water/heating to come on automatically as the red light on the boiler stays on constantly.

SOURCE: Vaillant combi boiler problem

when the tap is turned on and the water light on the boiler doesn't this means the diverter valve is not operating it could be down to low water pressure in the house this can be checked at the cold tap in the kitchen. if there is plenty of pressure then it could be the diagphram in the diverter valve is worn or split. the diagphram is only a few pounds but it depends on the engineer you get as to how much money he wants to fit it.
the egg timer symbol (or two pyramids together) is an ignition indicator turn off and on again to see if it will fire with the tap running. reset the boiler with the lower right hand control knob.

Hi my vaillant combi gives hot water for only 15 seconds then runs cold turn the tap off, run the water again & gets hot then runs cold some told me it might be the diverter valve can any body help...


yes it is your expansion vessel it sounds under charged to me?your expansion vessel needs to be recharged to 1 bar at least,but check manufacturers instructions it could state different.if the heating is fine and your getting hot water in intervals your diverta valve is moving and working?

Vaillant boiler no central heating but hot water ok


Could be a lot of things, but the issue appears to center on the heating circulation system. Possible causes I can think of:
  1. Thermostat setting is incorrect
  2. Thermostat is failing
  3. Main circulation pump for heat has failed
  4. Valve for heat circulation is closed

I have a Vaillant boiler Turbo Max VUW 242/1E, central heating is working but no hot water


Hi,

You have a faulty diverter valve, this is a fiddly job, you need to call in a 'Gas Safe' engineer to diagnose and replace this

I hope this helps
