Thermostatic mixer tap

[ssmith3110]

We just moved into our first flat and have one of these taps. Heating is hot, kitchen tap water is hot but the bath is Luke warm even at full temperature. How can I fix this?

Press Red button (override) down and turn at same time.

Yeah I tried that already and it’s still not very hot

Blocked filter on hot supply side ,possibly. But more likely the thermostatic valve needs adjusting ,or replacing.

How new is the flat?

What boiler do you have?

Ok, that should rule out no one has fitted a thermostatic mixing valve underneath. If you can remove the bath panel, run the tap on max hot and feel the pipe, if it’s hot I’d suggest the tap/thermostat is faulty.

First thing to try is take off the thermo head and see if the mixing setting can be increased to add more hot. You'll probably need to get hold of the MI's for the product to indicate how this is done... Usually something like turning the spindle with your fingers to get it hotter and then replacing the head at the same position you removed it... There's often a locking ring of some type that may also need rotating and reattaching.
