No problem Jan,
Its a shame some installers are only interested in making a sale, and forget to tell the end customer the ins and outs of vacuum tube solar water heaters.
I have seen a few failed units due to constant over heating, especially the high pressure type, steam is very powerful !
and if the safety valve becomes blocked ( with calcium build up ) something has to give !
In my opinion solar water heaters with a vented tank are better as water can boil out of the vent in the event of over heating.
Cheers Tony
