Immersion tank with two immersion?

[grandfortune]

Hi all, on a job and have three flats with immersion tanks in a separate boiler room. Immersion will be doing the hot water for the flats, I did run a 6.0mm to each of them as they are 15mtra away lucky I did as there are two immersion on each tank, just wondering the best way to wire it, I assume I can use a click cooker outlet that has two outlets in it but will a normal time switch for immersion be OK or is there a heftier one I'll need as I'm switching both immersions at the same time?
Cheers grand

Probably a time controlled contactor would be best.

Do the flats have economy 7?

If they do you probably want the lower immersion on a separate timer......

No economy 7

Panel heaters for heating the flat and hot water tank with the immersion in for hot water.

Cheers grand

I don't know the total kw but I would use a contactor.

Why does the architect think it needs 2 immersion per flat ?

Are you controlling each tank separately?

Use a contactor controlled by the time clock would be my choice

Do you mean 2 elements on each immersion heater? If so the bottom one would be used as the main heating element perhaps on a timer. and the top one as a boost. They wont be on at the same time.

Are the hot water tanks properly insulated?

If so, you probably don't need a timer.

thanks guys,

only small 1 bed flat so will just connect the bottom stat up, cheers

Without economy supply,it seems to me the top immersion is nothing more than a spare
It could be used as a small capacity heater for hand washing or such, then the choice of switching on the bottom immersion for baths and full capacity

Is this a HMO?
