Evening, we have a Potterton Promax HE Plus combi boiler.
Over the last few days the hot water has started be very intermittent
When you turn the hot tap on it fires the boiler and we get hot water, then after a few minutes if drops out water goes cold then kicks back in again. The temp guage goes to creepes upto 90 then kicks the boiler out this then drops to about 60-65 then the boiler kicks in again giving hot water but as soon as it hits 90 off it goes again.
Anyone any ideas ??
Thanks in advance
