Installing an immersion timer

st0nk

Hello,

So i want to install and immersion heater timer.

My timer is this one: http://imgur.com/a/WYJmu
At the moment I only have one switch and look like this: http://imgur.com/a/2wV71


So my questions is:

- Do I need to keep the old switch? or Can i replace the switch with the new timer and that is?

Thanks

Is that an On/Off Sink/Bath switch? If it is then if you want to replace it and the old timer, you will need to install a dual element timer, that's a timer that you program to come on and go off at times dictated by you and for each On/Off cycle you will have to select sink or bath.

To keep it simple, you can replace the old timer with a single element digital timer, that means that you keep the old switch and manually select Sink or Bath but leave the On/Off switch permanently On, as it probably is at the moment. Then if you're going on holidays, flip the old switch to Off and the timer settings won't matter because it will stay off until you come home.

Coylemj, thanks for your replay.

I only have a switch at the moment and no timer. I want to install a timer because i'm wasting so much energy.

My actual switch is only one way is on/off, is similar to this: http://s7g3.scene7.com/is/image//ae235?src=ae235/4343J_P&$prodImageMedium$

You can do either. Keep switch as a back up or just replace with clock. Just make sure clock is an immersion rated one.

+1 As above.

With only one element in the immersion (i.e. no Sink/Bath option), you can have a timer by itself and just manually set it to off when you're going away for a few days. Or keep the switch if you think that you might install a dual element at some stage in the future. If you have a timer and a switch, the mains feed should go to the timer first, then to the switch.

Some timers are designed for central heating and they cannot handle big loads so as punisher5112 says above, make sure that your timer can handle the current going to an immersion.

It says so at the top of the right-hand page in your second link - 'immersion timer'.
