customer complaint they got central heating but got no hot water on a Y plan system. my 1st thought was diverter valve. when around to have a look, here's what happen-
turn thermostat up and then turn central heating on- boiler fires up and diverter valve moves to heating side.
while the central heating was ON i turned ON hot water, but diverter wasnt moving to the middle.
so i put central heating OFF, diverter valve still staying at the heating side and boiler back to stand by mode.
then i turned thermostat down to 10oC then diverter valve moves to the hot water side and boiler fires up.
turn heating back on and thermosat up diverter valve moves to the middle. i got hot water and central heating.
why wont the hot water come on while the central heating is on or the thermostat is above room temperature?
