Where can I get a Computer operated power controller?
hellonearthisman: Would the US one need to be modded? It's 120v @ 20amp, would that have issues working on 240v?
Have a look at this link
Thanks, http://www.aviosys.com/ippower9258SX.htm looks more like my electrical skill level but the AMPs look a little low for a hotwater cylinder.
hellonearthisman: It's starting to make more sence.
I sorry for asking, but have you got some links to your other postings?
I also found these ARLEC Remote Control Power Switch - Triple Socket
Have to find out if they can handle the load, IR controlled.
