Ducted Aircon/Heater drawing over 250 watts in STAND BY!

Postby wattstar » Fri Oct 26, 2012 8:47 pm

I just recently had an efergy e2 energy monitor installed and I did the usual run around the house to see what uses what. To my shock I was still using about 500 watts with almost everything turned off. I have previously gone around and measured devices at the points so I have a rough idea of what uses what in stand by, my estimation I should be using 200 watts. But for some reason it was much more.

I decided to test at the fuse board and noticed that when I switched the aircon circuit off it dropped dramatically, I also checked the meter by going into the alt1 display and checking what the watts were with it on and with it off in case monitor hadn't been installed properly but it confirmed what I thought and is using over 250 watts when turned on at fuse board but off at control panel.

Has anyone else noticed this and is there anyway it can be fixed?

It will most likely be the compressor crank case heater, stops liquid refrigerant migrating to the compressor and causing damage on start up.

Thanks, I was worried there was something wrong with it.

Does turn off when the weather is warmer or does it just run 24/7?

Is it possible to find out how often it is drawing 250W for?

I can't monitor that exact appliance without having the other clamps removed but I can get a rough idea by checking it when everything else is turned off.

I only had the extra clamps installed today to measure hot water, stove and air con. I haven't noticed any drops as yet.

How often do you use it this time of year. You might have to get a switch hooked up that cuts all power to the unit and just switch it on 5 minutes before start up.

Surely you could work out a system with a delay on start relay and switch the whole thing of, until really needed, climate wise ...

I believed that the heaters were needed in cold climates. Try Google to see what you find.
There must be a practical way that it can be disconnected until really needed. eg. an external switch or a thermostat . You don't find them in normal smaller systems ..
