Yet another (again!) boiler Q

[oldmotherfoccer]

i fkn hate my combi, wish i had never had it, when it goes wrong, which in my case is often (main boilers hang your head i shame) we have no hot water, i will be fititing an electric shower, and i would say that should be mandatory if you are considering a combi. 

new pump, 2 new main boards, new gas tap, new regulator, new condensate unit, new timer, new burners, infact apart from the cover its all been replaced...... oh and its just about to be 4 years old !!!!
