Was just preparing to move these heaters, trying to rotate the heater inside the protective ribing, when I managed to twist the outer black cap by itself. I then discovered the red platic rod attached to the thermostat knob had sheared... 
I've managed to set the thermostat to the correct temp using a small screwdriver, but I'm worried if the waterproof seal has been comprimised?
Going to install the non-broken one for now and hope someone on here may have had a similar experience they can divulge.
