Have any of you used appliance power use monitors to measure how much power a device is using? I recently bought one that plugs into a wall socket and then you plug the appliance into the device and it tells you the voltage, amp draw, wattage and Kwh the appliance uses.
If I plug a fan heater into it with no other devices running, it says the heater is using 3300-3400 watts and 14 and a bit amps (we use 220-240volts here) However, if I plug a multiboard surge protector into the power monitor and plug the heater into the multiboard along with a computer, the heater is now only using about 2200 watts on the same setting-about 2300-2400 overall including the computer equipment (the heater still feels just as effective too). Then if I plug the power monitor into one of the multiboard sockets and the heater into the monitor,(so just the heater on the monitor without the computer) the monitor has it back at 3300-3400 watts. I don't know a huge amount about electricity but what could account for this difference in power use? Poor quality power monitor?
I have had this heater run before on 15amp circuits for more than half an hour plenty of times in the past with a PC running on the same circuit and no issues. It causes me to have a hard time believing the heater could really be 3300 watts.
Apologies if this isn't the right area to post this
