Fig. 12 Unmixed and mixed heating circuit
An absolute prerequisite for the connection is that a minimum flow of at
least 70% of the nominal flow can be maintained throughout the year.
* If a bypass is used and an external circulation pump is fitted, the flow
over the heating system can be reduced by 40% of the nominal flow of
the heat pump. Ensure that most of the thermostat valves are fully open.
Otherwise an accumulator tank of at least 100 litres in capacity must be
installed. The bypass length must be at least ten times that of the pipe's
inner dimension.
