Delivery of unit. The order date was Oct 13 2015. So delivery was within the formal delivery time of
90 days.
Jan 10
Connecting unit to grid. No load on unit at all. Monitor of Watts is inserted between wall socket and
the cable strip that is BEFORE input to Power Unit. This phase is 220 V/10 A fusage.
Jan 13
First load connected . 2 LED lamps. 6W + 9W . This load and all load from here on is added to the
OUTPUT side of the Power Unit.
Watt meter show 15-16 W
Jan 17
Status before new load is Watt meter 16 -18 W and no nano coating seen on the bare cables. Little
interesting the Watt increased a bit since load connect. Still it’s within fault margins for
measurement. Also we could see the total energy taken from grid was 1.5 kWh (kilo watt hours).
That’s pretty much what you should get from 16 W load 4 days.
16 x 24 x 4 = 1536 Wh = 1.5 kWh
What we add now is 3 table fans each adding some 27 Watt load. This ended up total load, all non
resistive very near 100 W.
Jan 20
Status after 3 days with the 100 W load. No nano coating seen. Total energy from grid now is 8.4
kWh. The last 3 days of 100 W load should add

100 x 24 x 3 = 7200 Wh = 7.2 kWh
If we add 1.5 kWh from previous metering give us 7.2 + 1.5 = 8.7 kWh total from start …. That’s
what energy we should have used in theory. So it’s 300 Wh more than what we see on meter.
Possibly a tiny indicator we are using less grid power than a normal house grid. Still it can also be
within fault margins.
Anyway after running the 10 min load of 428 W I could see the total W usage was down to some 72
W. Instead of 100 W ….
But then I noticed one of the 3 27 W fans was not running. Turned out it was broken. Did not work at
all even when I tried on the “normal” house grid. So my initial thinking that the power from grid was
reduced after connecting heat fan was not so. It was just one of the fans broken.
When running the heat fan we could see 545 W as input from grid. Theoretical we should have seen
524 W ( 96 + 428 W, see table 1). Not major diff enough for me to guess any about it … just like we
seem to see a tendency that meter from grid is slightly above what you expect from theory.
I will go on testing, not replacing the broken fan. My thinking is the 80 W load of the 3 fans has
already been doing it’s job. I don’t see it as a game changer that one of the fans broke.

Watts from grid gone down from 524 to 520 during these 67 days. Tell us nothing really since it’s
within fault margins. The kWh was a little surprise. We had 24.8 kWh. The energy increase in theory
should have been
2x(10+15+20+30+40+50+60)x524/60 = 3.9 kWh
If we add that to what we had before we get
8.4 + 3.9 = 12.3 kWh
What we read is pretty near double of what’s expected. Don’t have any good idea on this so far.
We’ll have to see what trend we get with the next load …
Jan 28
Total Watts gone down to 490 W during 20 hours of permanent heat fan. Is this a true decrease ?
Can’t really say.
Anyway we can check a little on the kWh now. I had 35 kWh on meter. Added this 20 hours now
should be
20 x 520 = 10400 Wh = 10.4 kWh
Adding that to yesterdays value
24.8 + 10.4 = 35.2 kWh
This makes more sense than the 24.8 value we had from yesterday ….
Adding the next heater we have 50 W less on meter compared to total Watt load
Again, is this a true indicator we consume less from grid ….. maybe, maybe not ;)
Next step will be to increase load time for the 1170W heater during 4 days. So on Monday Feb 1 we
will see what happens when we change the location of the 1170W load. That is going to be the most
important step trying to verify this device.
