"Max operating temperature up to 100°C/212F with external circuit board"
Odd that it mentions the external circuit board, that leaves it unclear if that means the pump is good to 100ºC or if the board/controls are good to 100ºC.
6.5m of head is not insignificant and it is nice that the units come with their own power supply. Wonder how easy it would be to hack into and extend the wires to a control panel?
Will ride for beer!
