Water change and heater cool down

[Negseven]

haven’t done a water change yet when I have had to turn off the heater to cool it down, so the element doesnt blow when the water goes down. How long do you reckon it takes before the Heater cools down? thanks

No time needed heater is never hot to touch mate i turn my off and start with maintenace immediatly no waiting at all.
Turn or pump also if u have internal its not recomeded to run it with no water.

I concur. No need to wait for it to cool down. Just un plug the heater and go on with your WC.
