    Hot Water problem

    When the hot water is switched on (emersion system) the central heating comes on at the same time. I have turned the hall thermostat down to zero, thinking this would help, but it doesn't. Any suggestions?

    3 way motorised valve

    I have recently drained the hot water and heating system to replace a radiator. Having flushed the system both HW and CH the only way I get get hot water is to run the central heating. I suspect the valve maybe clogged with the usual black gunge or could there be another explanation?
