For a 10.5kw electric shower. Will it make a difference or is it not something you should do?

Hi a9blue,
Generally electric showers are designed to work with constant mains pressure of a minimum 1-1.5bar depending on the manufacturer. It will depend on the type of booster you are proposing, most cut in when flow is detected so if you have say 0.5bar mains it is likely that your shower will turn off because of low pressure before the pump activates.
