40A Flow Switch

[LED Lighting]

Hi everyone

I am looking for a water flow sensor/switch to turn on a 11.5Kw shower.

The flow sensor/switch must be capable of handling 40A for a period of upto 2 hours of use.

Does anyone know of such a thing if one exists?

What's wrong with a contactor ?

Not herd of that before exactly how does it work

As Kasi says. Why would you want an electric shower to be on for 2 hours? Is that for continuous use?

Whatever it is for I would be checking with the manufacturer that the shower would be able to sustain 2 hours of uninterrupted use.

That was my question why would you use a flow switch you turn shower on get washed and then turn it off in my house lol

 

[driverman]

Exactly itselectric

It's probably a shower being adapted for some other use lol

Think you will find that showers are not designed to run for this length of time.

I knew you had heard of a contactor..........

I should of explained in the op.

the issue is this property is using a 5L (under sink) hot water tank to fill a bath, sinks, shower (non electric). The current tenants won't use the shower!

they have asked me to find away of filling the bath with hot water, I have looked at demand hot water heaters but can't find anything suitable.
I think the 2hrs was an over guess but could happen as tenant has been known to leave hot water tap on for hours.

has anyone else got any other ideas?

So basically you need instantaneous hot water heated by electricity in a sufficient quantity to fill a bath before the first water goes cold?

I hope this property has 3 phase.

No only single phase - domestic property

Think about the kw rating of gas combi boilers then work out why it can't be done with electricity.

What wrong with an old fashioned hot water tank with an immersion heater?
