Immersion losing heat

    Hi all, I'm not sure if this is a plumbing or electrical question.

    Over the last couple of weeks we've notice the amount of hot water we can get for a shower from our normal immersion setting has decreased. It starts warm but becomes cold much quicker than usual.

    I think I can track this back to when I removed bathroom towel radiators a couple of weeks ago for painting. I obviously had to reintroduce some water back into the system when running the gas boiler again to refill the radiators and bleed all the air out.

    I used the pressure gauge near the hot water tank to refill the system. I'm regretfully not sure where the turning valve was positioned before I started the process and feel where it is now might be letting cold water into the tank when the immersion should be heating the water. The valve has an "A" turning one way and a "C" turning the other. I've tried fully turning each way and somewhere in the middle with no help each time I use the immersion.

    Does it make sense that this might be affecting the water or am I way off?
    I've also read about resetting the immersion by taking the cap off the top of the tank and pressing the reset button. Would this help?
