Hot water issue...

[Muckerz]

hey guys!

I'm Jonny, from manchester... new to the forum, joined today when i came across a post that helped me get my boiler firing again.

so anyways, I've got an problem with my hot water, so i figured i'd see if any of you guys can help me.

Just recently i havent been able to run a decent bath... if you open the hot water tap fully, it gets moderatly warm for about a minute then runs cold.
If you open the hot water tap just slightly it runs warm, not hot, just warm.

It seems to get better if i turn the heating up to full before attempting to run a bath...

In the kitchen sink, the water runs hot when you turn the tap on, although perhaps not as hot as it used to.

Our boiler is a Worcester Combi 240 RSF.

Can anyone offer any advice on this problem?

Many thanks in advance

with the flow pipe off the boiler to the rads, cold. turn on your dhw. if the ch flow pipe gets warm.it could be your divertor valve passing to both heating and hot water,usually caused by a worn diaphragm in the diverter valve, easy to change though.try that first.
