Immersion timer for consumer unit?

peking97

Considering fitting an immersion timer soon.
Anyone know if its possible to replace the immersion circuit breaker in the consumer unit with a breaker that has a timer integrated into it?

Yes there is timers that fit into consumer units, not sure if they are rated for immersions though, have seen them used on heating systems once or twice in the past.

WIf you are considering it, it would need to be fitted by a RECI as only they can work on the consumer unit, for your safety!

Fitting a timer with booster button away from the fuse board is a far better option imo.

I know my immersion timer is completely separate from the consumer unit, and as above has a boost function.

If you already have an immersion, there should be no real extra wiring required only between the timer and the sink/bath switch.

Any thoughts on this particular timer?
It seems to be capable of switching up to 16 amps into a resistive load.

Dont believe this is the one you want, I had the timer in my consumer board in my previous house - it was double this width and was digital. It can be done and is useful if not boosting only timer as stops others messing with it.

Its rated 16a resistive but realistically you'd be using a contactor with it for the immersion if you want it to last.

A simple Apt timer under the distribution board or a economy 7 timer outside the hotpress would be better

I would consider the need for a contactor overkill.

it might last but generally those timers would be control and not switching of 3kw loads

Do happen to have a data sheet that suggests that it should be done with a contactor?

I have never seen the need for anything extra with a purely resistive load using a correctly rated switch.

Is an immersion timer that keeps going through power failures available ?

( So that the time on the time clock will not need to be adjusted following a power failure ... not that the immersion will continued to be powered during a power failure. )

I have this one installed around 10 years now. Keeps the time during power outages. It has a boost function so you will never have to worry about immersion being left on. There might be sexier looking ones out now but this one I highly recommend

Note it has a 4 hours memory reserve.

I saw that in the specs but ESB replaced a wooden pole with a metal one on the road a few weeks ago. Power off from 9:30am to after 6pm & it never lost a second. I'm guessing it's a guaranteed 4 hours minimum.

I expected that that was most likely, as 4 hours would be a bit tight. There are a few plug in timers out there that might do the job, but not as neat a job as those dedicated units.

Not for the immersion obviously-plug in timers
