    Timer to control more than one circuit.

    Timer to control more than one circuit. 17th May 18 at 9:05 AM
    Hi folks.

    We have a timer for our underfloor heating (UFH - electric) and I'm thinking of getting another timer to control the on/off of the heated towel rail in the bathroom. It's only needed during summer months, as it is a dual wet/electric.

    The thing is, I'm wondering if I could get just one timer to control both the HFH and the towel rail. One timer, two circuits and two sets of independent on/off times.

    Has anyone come across something like that?

    It would save having two unsightly timers with separate ways to set up and change. Also, I'm not impressed with the UGH timer we currently have - too inflexible.

    Cheers.

    You will need to find a two-gang timer, that is one with separate input and output with two independent timers all mounted in one box. Good luck with that search. If the electrical feed to the UFH and to the bathroom towel rail/radiator are close by then it makes sense to do what you are suggesting. If they are far apart or in separate rooms just go for two separately mounted timers. You could buy a couple of separate timers and mount them on a box yourself (assuming you have the competence/confidence).


    Something like this.

    In my experience, wall-mounted timers are expensive, inflexible and often unattractive (compared to central heating timer-thermostats which do a similar job).

    I've never seen a dual-circuit timeswitch in any of the main outlets (though that doesn't mean they don't exist). If you can find a central heating timer that has independent circuits for heating and hot water, then you might be able to use that?

    Thanks both.

    I did think that what I'm looking for doesn't exist. Just thought I'd ask.

    The problem is the loading. Most CH timers only switch 3 or 6 amps, your underfloor heating load especially is likely to be a lot more than about 700 watts.

    You could use CH timers along with contactors to switch the loads, but they're often comparatively expensive and make clicky noises as they clunk in and out.

    As above this could be done with contactors. Going to be expensive though. Get an Electrician to quote for the job.

    If you're putting two circuits through the same timer switch, you also need to consider where they are fed from, how they are fused and how they are isolated for safety and whether the timer affects that.

    Probably easier to keep them separate.

    The electronic hardwired timeswitches work well for towel rails - you can now even get WIFI controlled one (not got one of these myself)

    Dual channel timer, will switch 2.3kw.

    not a cheap solution

    https://uk.rs-online.com/web/p/surface-mount-time-switches/3970558/


    Should be able to find something to replace the existing wall plate(s) switch there are a lot out there when you google.
    try immersion heater timers


    800w towel rail drying solution, does not time for warm towel in the morning

    I've seen similar to the runback timer you mention - eg:

    https://www.ebay.co.uk/itm/Horstmann-E30-Electric-Towel-Rail-Digital-Timer-Switch-Energy-Saving-timer/282262243206?hash=item41b8240786:g:5soAAOSwNZtZv4j f

    But of course they don't allow you to time the towel rail to come on in advance. Still, that might be a solution for the summer, where we just want the towels to dry quickly but don't need the room heated.

    Cheers.

    We had a Sangamo 26404 4 way timer at work, expensive but worked well. There must be cheaper ones out there.

    That would work - if a little overkill - but you would need a large box and would need to mount a piece of DIN rail in it to mount the switch.

    Seeing that one prompted me to search for more Sangamo products and they do one called PR2N which claims to have two separate channels but when looking at the wiring diagram there is a common Live for the clock and the two channels. Check out the installation instruction here.

    We went with separate control and timers for our bathroom refits ... the underfloor had fancy controllers linked via WiFi to an app but were single channel.

    We opted for these...

    http://www.timeguard.com/products/time/immersion-and-general-purpose-timeswitches/wi-fi-controlled-fused-spur

    ...to control our dual fuel towel radiators. These were installed in our airing cupboard as they aren!!!8217;t IP rated but could easily have been installed outside the bathroom(s) adjacent to the towel rads, it was just neater to have them out of the way.

    You do HAVE to control these with an app, but they can be manually switched. There are no timer controls on the unit though.

    Find it handy as we can just switch them to boost if we have a bath and change the program for early starts etc without having to physically touch the thing. Works for us.
