New Heatline Boiler - CH Perfect but no DWH

[Blasphemous]

Hmmm, I'd try my suggestion above mate....

'Disconnect the DHW supply to one of the hot taps, connect a decent tap to the tap connector and try running it to see what the temp is like'.

Its not a massive job and it would at least discount the possibility of it being Poor Quality Taps that are the cause of this.

I also noticed that the picture you posted is a 'Shower Mixer Tap'. Is that the same 'Shower' you are having the problems with?

I'll give it a go mate, cheers.

I can isolate the hot water at the kitchen tap and swap the flexi's onto a new tap.

And yes the shower is the bath/shower mixer tap (i've tried it on both modes). I hope thats not the problem as its boxed and tiles under the bath
