8.4 System Type 6*
System 6 includes pool heating.
Additional heat can be mixed with heating from the buffer tank and output
into the heating circuit by a bivalent mixing valve (Y1).
Heat pumps 1 and 2 can be connected using 3-way valves that direct the
flow either to the DHW system or the heating circuit. The other heat pumps
are connected to the heating circuit.
Solar heating can be connected either to the DHW tank or to a buffer tank
using 3-way valves, or to a ground heating coil.
Cooling can easily be connected to the bedrock/ground source heating
circuit.
