Newby question - hot water heater control

Hi,

I'm fairly new to the home automation game so treading rather carefully. I have installed a Proliphix thermostat for the heating which I am very pleased with. As the next step I would like to be able to remotely turn on and off the (electric) water heater. I think the element is around 3KW.

Does anyone have a suggestion for an off the shelf solution for this? Ideal would be a suitable contactor with a built in webserver, but I've not found anything sensible so far.

It doesn't have to be wireless, wired to the network is ok.

Ideas?

TIA

/Simon

Check Poseidon, for example the Poseidon 3468.
hw-group.com/products/poseidon/poseidon ... 68_en.html

I use this also together with the Proliphix http://www.proliphix.com/

Poseidon 3468 alerts the operator to critical situations (contact opened/closed, or temperature/humidity out of safe range).
In case of an alarm, Poseidon sends an e-mail and connects to your NMS (Network Management System) with a SNMP trap.
Configuration and current sensor readings are accessible through a graphical WWW interface.

-IP thermostat function to control outputs locally
-2 outputs rated at 250V (double-throw relay contacts)
-Connect up to 4 temperature or humidity sensors and 4 Dry Contact inputs
-When a contact is closed, e-mails or SNMP traps are sent to multiple recipients

Thanks - looks like a nice unit, however a bit of overkill (and expensive) for what I was looking for.

I've now realised I may be able to use the fan relay contacts on the Proliphix to do what I need. There isn't a specific 'off' setting for the fan, but in my case, if I switch it to 'auto' it is off anyway,
