i have a Worcester 9.24 electonic central heating/hot water boiler,the
problem is unless the hot water tap in the sink is run very slowly the
water will not get hot,and when it does if you turn the tap up it gets
cold,the bath water upstairs does not get hot unless the central
heating is on,this is supposed to supply hot water on demand,when you
turn the hot tap on the boiler fires up but as described doesnt heat
the water,we have had the plumber out but all he says is the water
pressure in the taps is to much for the boiler,now this boiler used to
supply hot water on demand,so am i right in thinking the boiler is
misfiring(ie knackered),and is the plumber blagging so as not to give
us a new one,my landlord are the local authority,he stated that there
needs to be 3 things wrong with the boiler before they replace
it,,,,,just off now to clean up after my grandaughters rocking
horse,any assistance would be greatly appreciated

This sounds like the diverter valve (the bit that switches between water
heating and radiators). Perhaps the contract with the LA is very
unfavourable for undertaking such work?

Anyway keep banging away about how it was workable and now isn't. Ask for
second opinions. If all else fails go to a law centre or CAB and get heavy.

the bath water upstairs does not get hot unless the central
heating is on,

Sounds like a broken diverter. There are other possibilities, though.
