Good afternoon,
Our very simple solar water system has been up and running since the end of March. Even on cloudy days it provides more than enough hot water for our needs. We had no previous experience with solar water heating, so put this together in the simplest way.

You supplied the IT300-HP-HX, we hooked up its internal heat exchanger to our existing electric water heater by removing the electric heating elements and adding a manually switched circulating pump.

We find that by switching on the pump for only 15 or 20 minutes in the afternoons, we have plenty of hot water for the next 24 hours at least. * *In freezing weather, we rely on the heating coil in our wood-stove for hot water, as in the interest of simplicity, our solar system has no anti-freeze and will be drained.

This simple system works far better than expected, and your customer support has been over the top. I give you full marks in every category.

Many thanks and kind regards,
Jack and Erika W
