Works very well. Efficient enough to work in winter – I’ve had my Envirosun thermo-siphon with E25 panels through a Sydney winter and am able to run our household of 4 off 100% solar for many, maybe most days. Way more productive/efficient than my previous … My electricity consumption is down consistently throughout the year, on many winter days down by 40%/10kWh consistently (excluding overcast days).

Can’t be any happier after a couple of weeks of procrastination and putting up with cold showers because our system had died on us. Scott was able to respond immediately and had our new system installed in a timely manner. Wife is happy and that means life is good. Great price as well so many thanks guys. Highly recommend these guys.

Fantastic product and even better support. When I had a question about installation the Envirosun team called me back within the hour — no offshore call centres, just real Australians who know their stuff. The hot water savings speak for themselves.

We’ve had the Envirosun heat pump running for 18 months now and our electricity bills are down by nearly half. Lightweight system, straightforward install, and quality you can see. Exactly what it says on the tin.

I’ve specified Envirosun on three new builds now and every homeowner has come back to thank me. The 10-year warranty gives clients confidence, and the trade pricing gives me room to move. Genuinely the easiest recommendation I make.
