Poor shower pressure with combi boiler and accumulator

    I have just had a boiler, hot water tank and power shower pump replaced on advice by my plumber. I have two separate boilers, heat/hotwater systems in the house. This boiler was replaced by a combi boiler as it only heats the lounge and master bed and provides hot water to en-suite bathroom and utility room. Once installed the en-suite rainfall shower flow/pressure was woeful and so an accumulator was then installed. However mains pressure is so low, it can only charge accumulator to 1.5 bar so shower is more than a drip but still barely squeezes the droplets out. Water company says pressure is within acceptable limits.


    Looking for advice on how to solve without throwing the brand new combi away. Can I pump the incoming mains? Can I pump up the accumulator? Looking for a good solution that limits how much more money I need to spend but can get a decent shower.


    Many thanks

    Fit a cold water tank, then it can be pumped.
