Immersion Timer

Cmar-Ireland

I want to fit a timer on my immersion and I was wondering if this one would be suitable

Can anyone tell me if it will suit. I have a dual system (sink & bath) in the cylinder. Will this type work, even if it is just heating the bath coil.

I'd imagine that the timer will do the job. It will depend on whether how you have the sink/bath switch set. If you want to time the bath element at different times to the sink element you will probably need a 2 channel timer. Check to make sure your bath element is rated 3kW or less for use with the timer you listed.

i've fitted lots of them for gold-shield homes where theres two single immersions.in your case it'll likely replace the existing switch .its's two channel but the second channel is just a boost for washing dishes etc so that'll likely switch the sink element with the timed channel controlling the bath side

Just been reading up on the manuals on the Horstmann site.
i figure that if I connect the timed circuit to the bath element and the boost circuit to the sink, it should work properly.

Am i correct in saying that the bath element will heat the whole tank as it heats from the bottom up and hot water rises so circulating the entire tank and the sink element just heats the top as the water cannot rise so the bottom stays cold??

Cheers for the replies!!!

Reading the manual on this timer, it seems the shorts switching time is 4 hours. I wonder if this is too long? How long does a typical tank take to heat up using the bath element?
Is the electricty rate cheaper here in Ireland?

1 hour for the bath - shorter in summer an longer in winter.

Approx €0.43 (3 units)

10-15 minutes for the shower

Approx €0.06 (0.4 unit)

i forgot to say.the timed section is fixed to come on for 3 or 4 hours every 24
it's really designed for night saver/gold shield where the cylinder is fully heated at night on cheap rate

Sounds like a waste of money.

Set it to suit your own requirements. Perhaps an hour on Bath in the morning before you get up to heat up the whole cylinder.

you can't. it's specifically made for nightsaver .heats the cylinder at night-rate for a few hours with a manual boost during the day.it's a quality timer but you might need to consider night-saver for this timer

Any recommendations for a quality timer that has shorter switching times?
I've seen ones in the local hardware shop, but they seem very light quality.

The flash immermat time switch is a quality one ~€25 in an elec wholesalers.
There is a teac one, but I find them crap.

In my experience they dont tend to last as long. But it all varies.
It doesn't mean it wont work, you can trust it, but I like using the Flash ones.

A customer one time told me she got charged €45 for a flash timer in woodies, and it was the old model.
