Electric showers heat water at the unit
They can still produce hot water if the boiler is unavailable, but flow can feel lower in cold weather. The existing cable and protective devices must suit the unit power.
Mixer showers use the home's hot water
A thermostatic mixer can give stronger flow where the boiler or cylinder and pressure can supply it. Other water use in the home may affect performance.
Think about servicing and controls
Exposed mixers are easier to reach, while concealed valves look cleaner but need planned access. Choose controls that every user can grip and understand.
What to remember
Survey the water and electrical systems before buying either shower. Product power alone does not predict comfort.Bathroom fitters Glasgow
