Why is my shower not hot?

Our electric shower is producing water that is not very hot, even on the hottest setting… what might be the reason for this? It used to run much hotter… sometimes when we switch to high power it gets a bit hotter initially but then levels out again…

"It sound's like the temperature sensor could be on its way out. They can get damaged if there is a change in water pressure which the manufacturer won't cover under their warranty. The cost to change against buying a new one depending on style can work out cheaper and most come with a 2-year warranty whereas changing the part is only 1 year and something else could go wrong ending up through good money away apposed to just replacing with a new unit."

Economically it's best to buy and install a new unit that will have a limited warranty and give you controlled hot water."
