We can now conclude that the LHM is by far the most efficient (I continue the experiment, it does not cost much), if I left the bottle of LHM under the same conditions and if the 1g lost is not a measurement error. , it would take more than 5000 days to empty it, or more than 13 years!
5W40 engine oil blocks evaporation fairly well .... factor of 6 compared to the indicator.
The other oils are between 2 and 3 reduction factor, i.e. 2 times less than 5W40.
The 3 oils made emulsions + or - degeux with water except ISO 46 and especially LHM ...
The balls stop almost nothing (but slow down a little anyway: -20% daily evaporation) ...
Small more general question related to your solar system, it is the feedback that interests me, I am considering such a system for a new construction.
Did you put somewhere on the forum the sizing of your installation and the balance sheet?
Sensor surface, buffer volume, buffer insulation (?), Wall insulation, house surface, additional heating?
