Yes as I said, it looks like a combi cylinder, but the OP says they get near mains pressure hot water from taps, so dhw supply is more than likely passing through some sort of heat exchanger making it a thermal store and hence the need for a tmv.
Would like to see what's behind the red jacket to left of cylinder.

Kevin, I took out a thermal store which looked just like that!
The top section was a header tank for the store and heating system.
I dont remember that one but I dont think there was any mixing valve on the outlet.
However, on another store I took out there was a mixing valve.
I am still concerned that this reg installer is apparently unable to determine whats wrong. That does not do much for the reputation of our trade.

Guys thanks everyone for all their comments and help.
There is a 3 way valve, it's actually to the right of the cylinder in the photo I posted. The installer is here at the moment and he's going to change it for me at no cost. He'd already come to the conclusion that it was probably the issue. I'm going to make sure he stays here until I'm happy this time!!
Unfortunately he's also here doing another "boiler" installation fix. The condenser outlet pipe froze on Thursday night when it was around -15 here so the boiler locked out and hasn't been working since. He's rerouting and putting extra lagging on the outlet pipework.....
Apparently this is the 8th job he's had to do like this this year with some people he did installs for 3 years ago having to call him back.
Once again though thanks everyone. I'll let you know how it's worked out.
Very impressed by this forum so far!
