These systems are all over south america. I stayed somewhere using one in Argentina and the water coming out of it was hotter than from our gas boiler at home. They work almost too well!!!

It’s very location sensitive, but I think hybrid systems with heat pumps could help out a lot decarbonization.

In frost free locations these are very interesting because both upfront cost and yield will be much better. The reason is simple, you don’t need antifreeze, so you don’t need an extra heat exchanger or pump. These units work without any pump, by putting the buffer volume on top of the thermal solar panel you get circulation automatically (hot water will rise from expansion and colder water will flow through the panel).
