I have 2 of these pumps, running a solar hot water panel and a heat exchanger. The hot water panel one runs almost every day and has performed perfectly for nearly a year now. The flow rate is perfect for solar hot water from my 4 m2 panel.

The pump is outside, and is pumping a water and screenwash mix (antifreeze) without any problems in all weathers.
