Most of the new valiant boilers you can on the boiler Display give so many KW to heating and hot water just check this . if the heating has not been used in summer most times the pump gets stuck free this up with big screwdriver I have also seen the nut behind the chrome screw on pump turn but the impeller stays put? As with Most of the new Boilers Valiant. Glow- worm. Worchester 30 CDI you can Map the Pump you should look at this as well . I think you should be ok if you are only touching the wet side of system To put it another way if AAV went in boiler and water flooding every were and in order to stop this you could turn off isolation valves I know what I would do
