Shelly for Immersion Heater?

[SUNRAY]

That's not the type of landlord that I would work for!

For air B&B properties this is a totally standard arrangement for when the property is empty, also on night storage heaters.

The biggest problem is some hirers think they are doing a good thing by lifting the DO NOT SWITCH OFF cover on isolators and switching them off.

 

[SUNRAY]

You could use a bog standard smart relay to drive a contactor which then switches the load, it'll need a little wiring and some kind of enclosure though.

This tends to be the way it's done.

One of these is fine if the idea is not to control usage during tenant stays:

One of these can easily be left on advance and boost the leccy bill

I leave my car out in the cold all the time

 

[SUNRAY]

Also one of the horsmann units had a physical switch for boost without any timer involved in that setting.

Aahhhhh

Aahhhhh

No it's colder than that...

Oh no it isn't...

My apologies panto season strikes again.

Not the unit I was thinking about but this modern version looks like both elements could be left on 24/7 (Subject to of peak being active)

I am sure it won't allow that

Unless the place is on economy 7

Has no one read the requirements?

OP wishes to be able to remotely switch the heater off when unnoccupied which is a very common requirement for AirB&B properties, there is no need to retain a tank full of hot water for days or weeks on end.

But the OP is a daft proposition

My suggestion gives a simple alternative solution

Without personal experience of them I don't know, however with the top switch on what is there to stop the heater being enabled?
With the bottom switch on what is there to stop the heater being enabled during cheap rate E7?

That feels like 24/7 to me.

But the OP is a daft proposition

For wishing to save the planets valuable resources, for wishing to reduce the greenhouse gasses, for wishing to save money.

All I can see you're offering is a timer on the boost. Unless you're suggesting that as the only method of control (one which I personally think would be a silly and unreasonable system) how does that switch anything off?
