Immersion Timer Switch / Gas Boiler Setting

    Hi there,
    I'm looking for a timer switch for my immersion to feed the showers in the morning as I don't have the central heating on.
    Is it possible to get a switch that integrates the timing and also the sink/bath switch on the existing immersion?

    Alternatively, is it possibe to adjust the gas boiler to just heat water without having to turn off all the rads. I've tried lowering the thermostats in the hall and landing only to discover that these are broken and have since been overridden at the box in the hotpress. Does turning the boiler down to minimum work?

    Yes, you can pick up an immersion timer in any hardware store.
    You have to manually change over the sink/bath function though.

    There is usually an electric valve on the piping to the rads which will isolate them as required. Depending on your requirement, this could be set on a timer, or integrated into a control unit.
    The valve is usually a box approx 3" x 3" x 3" near to the boiler. If you aren't able to locate a valve, best get one fitted!

    It depends on how you're heating was plumbed in. If there's a separate pipe feeding the coil in the hot water tank then it should be possible. I.E. If the hot water pipe branches into two pipes near the boiler

    Look for a valve near the boiler to turn off the central heating circuit and leave on the water circuit

    Or you should find something looking like this

    though it might be like mine and not working.
    Its supposed to work fron either a timer or a room thermostat.
    It turns off the water to the rads but you can still have the cylinder being heated.

    I didnt bother replacing mine, just fitteed thermostatic radiator valves instead, does the same thing on a more granular level.
