I have inherited the boiler with the property. Heating comes on OK with timer or manually and gives good heat. The Domestic Hot water is however a problem as when the tap is on full bore it only then starts to heat and is very cool.
My first instinct is the Flow Sensor as I have had a previous boiler with a similar issue however this boiler is considerably different to anything I have had before and there looks to be only one sensor of this type in the Viso 24.
If it was a thermistor issue I think we would have no hot anything or too hot so need urgent advice to get this working before the cold weather bites !
Suggestions please.
