baxi 105e pressure at zero in morning before system starts?
in morning, no preheat on or central heating and pressure at zero, after preheat turned up pressure increases. is it normal for pressure to be zero when system is off
On my baxi 105e, the pressure remains above 1 unless water is being lost from the system.
Check to see if you have a slow leak at the back of the hot water diaphragm housing.
