Hi I Have an ideal logic+ combi 30 boiler when ever I run hot water I struggle to get any if I have tap on to high it cones through warm at best if I turn the tap down ill get hot water (not enough to do washing up) but if I turn it down bit to far it'll go cold and boiler says pump over run and then post fan perge or if I run the hot water for to long it does the same. I have had a plumber out 4 times he has even called the manufacturer wile here both saying nothing is wrong with it but this can't be true as it would make the boiler completely useless for hot water as the heating seems to work OK.
