Hi Guys,
I have a holiday flat which I use every couple of months. The heating system and hot water system gets its heat from a 9kw electric hot water tank. Essentially this tank is on all of the time.

I don't want to just physically turn it off top safe power. As well as the convenience of having heat when I arrive, I would also want the heating to work if temperatures head to freezing.

I have broadband and wireless in the flat.

I'm looking for a way to turn the 9kw heater on/off remotely using the internet. I have saw some products that can mount directly in the fuse panel but I far as I can tell they can only switch 2kw.

Does anybody have any ideas.
