In this article at https://ensia.com/features/solar-water-heaters-israel-renewable-energy-thermal-photovoltaic/ these are the opening words:-
“October 28, 2020 — For Gershon Grossman and Ed Murray, 1978 was a big year. Grossman, then a solar energy pioneer at the Technion, Israel’s premier technological institute, was launching the first International Conference on the Application of Solar Energy. Murray, an idealist attending college, joined an upstart solar heating company in Sacramento, California’s capital, drawn by a prescient concern about climate change and, as he puts it, an impulse to “save the world.” For both, the excitement was palpable. Solar water heaters were surging into the market, solar thermal energy showed broad potential, and the two were riding the wave.
Four decades later, however, they live in two different worlds. In Israel, 85% of households get hot water from a dud shemesh, or “sun boiler.” But in the U.S., despite decades of advocacy by Murray and others, the number of households that have a solar water heater is less than 1%. In California, many people don’t even know the technology exists.”
As colleagues will know, there are very many of these throughout Greece and in other Mediterranean countries.
I am aware that technically the name for these in Greek is θερμοσίφωνες but I want to know whether there is a commonly used term for these like the Hebrew dud shemesh, which means literally ‘sun tank/ boiler’. Is there a corresponding simpler and (more accurate?) Greek term for these objects? A ‘hot tornado’ is a possible translation of θερμοσίφωνας when I heard the term first. But that is down to my ignorance!

And it seems to me necessary to dd the qualifying adjective ηλιακός to θερμοσίφωνας which on its own could mean any type of water heater.
