I have a vaillant turbomax 28kw which is working fine but gives the occasional trouble.What is does is reaches its temperature very quick if and then turns off.It only happens on heating demand.If i select the control knob on 3/4 of the system it says 72 degrees on the display.The boiler then starts and the temperature rises very quickly on lcd.The boiler then turns off and starts again after few minutes.I have no issues otherwise as pcb was changed just last week( a reconditioned one off ebay with a year's warranty)
The gas safe engineer who changed the part said he can get a Worcester fitted and supplied for £1000 but said that the old one is good enough so it is up to me to make my mind up.
What are the thoughts on this please.Is it worth it as the present one will probably last me another 10 years as it has regular maintenance except the above problem.I have discussed it with the engineer and he did not know what was causing it so recommended a new one.
