So, I finally got round to sorting this... I noticed that the hot feed to the upstairs shower was hot when running the shower - too hot to touch. So on a hunch I bought a new bar shower (non-thermostatic this time) and fitted it this afternoon. Lo and behold, everything is now wonderful...

Yep, there are isolators on that one. That is the newest of all the sink mixers though, I changed it myself a couple of years ago.

65 is as high as it goes for DHW... only CH goes to 70. I can check the hot water in the kitchen tap as that is ~2m from the boiler

Heh, the box was put in after the last service - the same bloke who does the servicing (and installed the boiler)... I asked him to box it off when he serviced it last time.

I have just tried something with the upstairs sink - mixer over to hot, full on, water comes out quite hot but not too hot to hold my hand under. Switch the flow down to around half and it immediately goes completely cold. Does that suggest the mixer being fubar and the mains cold is pushing...

That's what I though, but they are all sealed up by the guy who did it... Even though I asked him not to and he said he wouldn't! Oh well, I'll have to crack it open and reseal it.

I'm not sure how to do that - all the pipes to the boiler are boxed off

It's a combi so no hot water tank and all cold is mains fed.

Hi all, hope someone can give some advice. We have a 2.5 year old Vaillant Ecotec Plus 837 (installed May 2014) that has had it's 2 annual services (May 2015 & June 2016). CH is fine, no problems at all. HW goes to kitchen sink (mixer), downstairs sink (separate), downstairs shower...
