You can see live performance charts and gauges of my heating system on this page of my website. On a good sunny day in the winter the system can raise the 80 gallon storage tank temperature by over 40°F. The stored heat is then fed to baseboard radiators at night as needed. If the stored water temperature drops below 140°F a Bosch Aquastar boiler automatically makes up the difference to ensure that heating water is always delivered to the radiators at 140°F.
