Electrical – How many wattage is your bathroom electric heater actually

electrical

The omni wattmeter can't show power factor. The US KillAWatt meter can? But it doesn't have 240v version so I'm stuck with the only wattmeter in my country.

I need to determine maximum wattage that can be drawn because i'm migrating it to subpanel with total whole house GFCI breakers.

This is the heating elements:

Notice the last 2 were wired shorted. So are these one or two heating elements pair? How is it wired?

This is thermal scan of the heating elements a few seconds after turning on the faucet.

It shows all are energized.

This is the reading in the plug-in wattmeter showing 1278 Watts while the faucet is turned on and thermal scanner on.

This is top left side of heating elements showing the thermal cutoff fuse (once it tripped and the technician taught me how to push it to turn it back on):

What kind of usage that you can enable the entire 6000watts of heater element? I can't seem to get the wattage in my WattAMeter. Is it an overated heater? Based on the internal parts. Which one is the heating elements? I want to know how many there are. Also if it's really 6000watts/240v= 25A, the plug is only rated for 15A and could melt.

It's a Multipoint electric heater in bathroom. Since it has no EGC, it's connected to a GFCI breaker. I'm trying to estimate the wattage actually used. I plugged a KillAWatt meter to measure wattage consumption. It has at most only 1800 Watts maximum at all temperature which is about 1800/240v= 7A. Although it averages 1200 Watts most of the time. I have two of these exact units so it can't be both are defective. They heat well. But the specs of the heater says it is 6kW. Why is the meter showing smaller value of the wattage? Also the temperature setting is supposed to just control water flow, right? I used medium and maximum setting, the wattage didn't change. What wattage did you actually measure and what is the theoretical one that should come out?

I only see 1 heating element on that 6kw heater is there a second one in the back? I did notice one of the wires going through what may be a current transformer so the unit can detect the amount of power being used. With the temp control being electronic there may be some calibration settings since it has electronic control turn the temp knob all the way up and flow as much water through as possible. If your water is reaching temp it may not draw the full 25 amps that a 6kw heater can require. If your water is not reaching the correct temp and you are not drawing full amperage the control board(s) may be faulty, contact alpha. From looking on line this could be a common problem if less than a year old it should be under warranty and the comments on line were positive about alphas customer service.
