Water not heating up to the proper extent can be a frequent issue associated with electric shower systems.
There are two main problems that tend to lead to lukewarm water emerging from electric showers – the first of which is a lack of power managing to get through to the micro switch.
The other most common cause is a fault with the heating element, which will curtail the water from heating up in the way that it should.
A micro switch will typically be less expensive to replace than a heating element, so the former problem could prove less troublesome to tackle.
