11.14 Basic system diagram 14:
2 collector arrays, 1 storage cylinder, auxiliary heating
System 14 has two collector surfaces, one
storage cylinder and one auxiliary heating
function. The control unit regulates the solar
function (temperature difference regulation
for 2 collector arrays) and the auxiliary
heating (thermostat, timeframe). Heat
metering is also possible, e.g. using an
impeller flow meter.
K1 = Collector array 1
K2 = Collector array 2
