slow heating up

[davedrew100]

hi
i would appreciate some advice. i have an intergas raid 11radiators 3 years old. i've noticed rads are now slow to get pipping hot. boiler temp slow to rise . i put in service boast mode for 15min to get the boiler temp up to 80 degrees which does the trick and all is well. just a pain in the ass having to do this everytime just to get it up to temp.
i thought it was scale sludge etc but considering it fine on service boast and stays nice and warm for the duration thats not the reason. sludge filter needs cleaning im sure as its 3 years now since cleaned!
would anyone know why it is slow getting up to temp? thanks a mill

Perhaps the boiler temperature needs turning up maybe?
