i've got a worcester bosch highflow cdi floor standing combi.
problem is if the domestic hot water is off and water is run, then the pressure in the system falls from 1.5 bars to .5bars
when the domestic hot water is switched on the pressure rises back to 1.5 bars.
i thought the domestic hot water and the pressure were not connected in any way. this has been happening since christmas.
does anyone know what could be causing this ?
