No vacuum on the HBV is not a problem in winter because vacuum turns the valve OFF to provide no heating when using the air con in the summer.

hang on have i made a mistake   i think no vacuum means water runs through hbv therefore giving you heat

I'm guessing now, possibly the outside temperature sensor tells the Climate Control its cold outside so do not turn off the heating even though the A/C is on to dry the air.  Or maybe its the internal temp sensor tells the CC the cabin temp is too low (rather that too high) so keeps the heating on.  Or possibly a combination of the two.

vacuum turns the valve OFF
