Tribune HE - luke warm water in shower but hot in kitchen

[KrisR]

Hi

I have Tribune HE electric boiler in my flat. It has been no problem with it for at least 5 years now. However recently I noticed a worrying problem. When I shower, I noticed the water became luke warm, not hot enough. I have a scale on my tap. Previously to get hot water, I had to turn the tap on at 30 - 35C. Now, to get hot enough water, I have to set the tap to even 45C, then the temperature is right.
But water in my kitchen is normally hot and I haven't noticed any problems.

Can you advice what could be a problem? Maybe there is something I can adjust on my boiler and solve this before I call a plumber? Thank for advice.

The only thermostat I can find in the system is located on heater element. It can't be this because heating element is warming whole boiler. I wouldn't have hot water in the kitchen.

The shower is likely to have an integral thermostat, which you won't be able to see. If all hot water other than shower is OK, then, as above, the most likely culprit is the thermostatic shower cartridge.

If you can find a name an model for your shower, you should be able to find a replacement via a plumber's merchant or the internet. If you can't find a name, send a photograph to showerdoc.com.

Thank you all for your advice. You are right, the shower has internal thermostat. I've already ordered replacement and waiting for delivery. If I don't post anything within a week, it means the problem is solved.
