Luke Warm Water from Hot Tap

[Riley]

The water should be leaving the hot water cylinder at a higher temp than 37°c your system has either not been set up correctly temp wise or you have cold hackfeeding. The only way you are going to diagnose is to isolate micers

Has someone checked the non return in the shower? back flow issue

I also believe it to be a backflow issue. Will get someone to check. I assume the non return would be built into the cartridge. Right?

It might be behind the shower valve depending on what shower you have. If you can isolate the shower valve you may have you answer. Unfortunately some of the cheap mixer taps can also create the same problem. If its the shower you may be able to just replace the front section.

I don’t know where to look for that. No obvious controls without removing covers.

Sorry its nothing you will be able to check without removing covers. It will need to be check by someone qualified. How do you know the water leaving the cylinder is 37c?

Heat probe gun (IR) pointed at the pipe ...

If your cylinder is fully heated to 60-65c I am surprised it is only leaving at 37c is that at the top of the cylinder?
