At home, the water comes above the level, and when the pump stops, the air rises in the panels. Hence my question.

Because it creates a stir, conducive to the creation of emulsions.

In terms of sealing and pressurization, one solution would be to vent with a condenser which brings the water back into the tank. (a coil and/or a long sloping pipe that goes through cool places)

The exchangers are the secondary circuit, I was talking about the primary circuit which circulates in the panels, with air bubbles...

Hi Christophe, and everyone, Not a bad idea of ​​wax, less "gross" than the LHM... :mrgreen: Were you able to measure the melting point temperature? In your buffer, how does the hot water from the panels arrive? under or on the surface? And where does the air come from that fills the panels every so...

Thank you Izentrop for this document. It is clear that the cos phi only applies to purely inductive circuits, with electronic devices it is more accurate to speak of power factor. For the oscillator, I have one that has been lying around in the attic for fifteen years, I hadn't managed to make it work...

Hello,
I don't have a swing...
The box is glued, no screws, I will still do a few tests before sawing it.

... If you put it on a socket further away from the measurement, like 10m (so more on the cables), what does it do on the Sinotimer? He has to be after the counter, of course, but the distance doesn't matter. I tried with a 40m reel. I do think, however, that the distance between the fa...

Haven't opened the box yet. It's supposed to improve the fp, but it does the opposite, it brings it back to 0.00... for the Chinese meter. For the pm231 it also lowers it, because of the 140mA it consumes with an fp of 0.01, the measured values ​​remain logical. With 0.5W of additional consumption! ...

I found something weird in some recycled boxes. I thought it was an ultrasonic mosquito repellent, but it's an "electricity saver", it's called "power factor saver", it makes sense from the packaging to lower the electricity bill :P pfs graph.JPG pfs plaq....
