Its Ok, you are supposed to be able to take them off and put those plain caps on for decorating and so on. It won't cause a leak - just screw it back on again.

there is probably a knurled chrome nut on the bottom of the plastic top, that screws down onto the metal valve. Screw it up to max temp before putting it on/taking it off, as that reduces pressure on the pin. Only let it press the pin downwards, not sideways.

If the plastic part has broken, or the nut has come off it, you can get a new one if you know the make and model. Although spare parts are available, it is easier and cheaper to buy a complete new TRV and swap the tops.

The top is not a water part so it will not leak. Set the temp to about 3, or half way. You should not need to turn it up or down often, as the thermostat will maintain your desired temperature.

Turning the stat up does not make it heat up faster.
