Is it usual to run a shower off the combi hot water - I thought most people had electric showers.

Been this way always,no problems
The boiler is lit by a diaphragm operated switch. If the switch is faulty (torn diaphragm?) it will need a bigger water flow to operate. Maybe the water flow to the shower is insufficient. See if it works at the tap with just a trickle.

On the tap It does not work until a steady flow so thx
Hubby says check your pressure and if necessary turn it up.
Our combi boiler runs our shower quite adequately.

The pressure setting is the pressure in the radiator system - nowt to do with the hot water.
