11.6 Basic system diagram 6:
1 collector array, 1 storage cylinder, auxiliary heating, return line temperature increase
System 6 has one collector surface, one
storage cylinder, one auxiliary heating
function (thermostat, timeframe) and one
return line temperature increase. The
control unit controls the solar function
(temperature difference regulation), the
auxiliary heating (thermostat, timeframe)
and the return line temperature increase
(temperature difference regulation). Heat
metering is also possible, e.g. using an
impeller flow meter.
