Is this normal in an electric shower?

In an electric shower if you have it running and at a nice temperature, then switch it off, should the water be very hot for a second or so when you switch it back on.

I did this the other day and was nearly scalded.:eek:Couldn't jump out of the way of the water fast enough.

Mines the opposite, if I turn it off and then on again shortly afterwards it goes freezing cold for a about 30secs before going back to normal temp.

This is perfectly normal.

When you turn off the shower you have a heating can full of hot water. The element is still hot & therefore still heating the water. If you turn it on again within a minute it will be scalding. I'm pretty sure that it warns of this in the manual.

It's always a good idea to run the shower on cold for 10 seconds before you turn it off. When you leave the heating can full of hot water this is when limescale builds up the most.

Thanks Sleeper, good to hear its normal.

Manual you say? What are these strange things you talk of?
