I have just had a heatline C24 boiler installed but for some reason when you put the boiler into summber mode just to heat up the hot water and not the central heating nothing happens. As soon as you switch it over to winter mode which is the heating and hot water the boiler kicks in no problem and my heating works fine, but for my hot water i might get a minute of hot/warmish water but not for long. Anyone got any advice they could give me please as to why it wont heat my hot water?
Thanks
Paul
