Hi,
I hope someone experience in combi boilers can help...........
When i turn on the hot tap, it stays warm for an age, and may eventually rise to an acceptable temp for a shower etc. There seems to be a trick though... If i reduce the flow considerably, the water will get hot, and if I then increase the flow to normal, it all seems to be OK for a time, then it will go luke warm again.
Observations:
- Central heating is fine
- The gas 'flames' look steady and do not modulate in height at any point
- A firm has diagnosed the gas control valve saying the pressure one side was different than the other side??
Can anyone confirm that this valve may be causing the fault?? - My reservation is that the Central heating is OK, so why could it be the valve
Many thanks for some expertise here
