These Pro-line heaters offer ultimate flexibility in that the element is submersed in the pond water (no added flow restriction) and thermostats can be used independently.
Should either unit fail, they can therefore be replaced individually and systems can be upgraded from 2kw to 3kw using the same thermostat.
