Ive changed over my oil boiler for a new gas fed cd 32 worcester condensing boiler .The heating is fine but the shower flow pulsates and if we turn a different tap on the water flow drastically reduces can you help/

a) Get yourself a combi friendly shower unit.

b) A combination boiler is only really suitable for supplying x1 hot tap at a time, some models like the Vaillant AquaPlus can supply several, but even they are limited as they can only supply say x2 taps for upto 5 minutes or so.


There's not much else I can advise, your installer should have warned you of the differences between combi's and system boilers at the time of sale.
