Our WF1K Wet Flue wetback module is designed and engineered in Melbourne and developed to work with pressurised and non-pressurised solar hot water systems.
It works very well with low pressure thermosiphon or you can add a TOPSFLO circulation pump to assist water movement.

Stainless steel welds are impeccable and workmanship is of the highest standard.

With over 18 metres of piping between two stainless steel walls you get consistent and even heat with a long lifespan.
