You really should get a whole house monitor and get ready for an eye opener on how much power draw all those little " trivial " devices can have.
Believe me, they do add up quickly. Also great for showing your significant other why you don't set the thermostat to 75+ in the Winter. My heater pulls 11Kw when running :|
The one I use is called TED ( The Energy Detective ). It's not the current generation model, but it gets the job done. The newer one is more accurate and has a few bells and whistles I don't have. Go read about it here I'm not sure if they make them for overseas customers ( it's US based ) or if you all have similar products available to you.
Once the thing is up and running, the first thought you have is what the hell is drawing all this power ? You then wander around the house turning various things on and off to see what the power draw actually is. My entire entertainment center is now on a power strip that I can kill with a single switch. ( Except for the damn cable box, rebooting those means a 10-15 minute wait while it goes through it's boot process :| )
In the end, I was able to get the power draw down to ~250-280 watts when we're not at home. Some things I simply cannot shut off. ( Bird cage lights, aquarium lights and pumps, alarm, etc. ) The fridge is the only thing that really cycles on / off as we have the hot water heater on a timer of its own.
Very useful little gadget imo.
